THIS IS GENIUS. Why haven't we figured this out before? Whenever I go to Africa and South America I always make sure to pack a ridiculous amount of batteries. People always ask me for them because batteries which you purchase in country are horrible. This blending of an ancient technology with a new technology is a game changer, and as a mechanical engineer, I find it to be super exciting.
For those wondering, the units are just under $10, so the payback for a family in a developing nation should end up being about 3 months. This effectively eliminates the kerosene lighting poverty trap that millions of people fall into. I absolutely love it when engineering innovation solves an economic and environmental issue.

Turning heavy into light.
Hey, who turned on the heavy?
+BBBuilds12 Your mom.
+Caleb Limb There's that word again! Heavy! Why are things so heavy in the future, is there a problem with the Earth's gravitational pull?
+Caleb Limb Yeah, it's not turning gravity into anything, it's turning the force/effort used to lift the heavy object up off the ground into depreciated power output over time...
+LeastComicStanding So, it's just turning gravitational force into light.
back in the 2019 they thought gravity was infinite... here we are now.. floating around. It all started with this lamp
Daniel De Lauretis this commet is golden 😂
Daniel De Lauretis They HAD to monopolised everything including gravity
Lmao
I'd say it does not work with gravity, It works by the force and energy we put in the weights when we lif them up and hook them.
@@sajjadjafari2612 yes, that's where the energy comes from. You're transforming your calories into gravitational potential energy by lifting the weights up, which then becomes kinetic energy as the weight falls, driving a motor producing electrical energy, that then runs through an LED to produce light. Pretty darn neat.
Stop wasting gravity.
+Rodrigo Appendino ha ha ha. Just tell anyone you don't like to go stand in a gravity powered generator so at least their existence will produce something... :P
lmao
this is my favorite comment in a long while, thanks :)
Gravity
2015: 9,8 m/s²
2115: 5,6 m/s²
Exactly, children in Africa could've eaten that gravity.
Brilliant!
The most impressive part is subtle. The LEDs are shunt voltage limiters, so at a certain point they want to draw excessive current. Start to approach that higher current and the extra load makes the motor/generator harder to turn, and that is like pinching the last high speed gear - it wants to stop. A super simple electo-mechanical governor. Love it.
but I imagine there is a heavy enough gravity load that could be applied that would blast through the resistance of the motor, right?
@@vincent21212 sort off.. the motor (generator really) wants to stop because the high current makes it very hard to turn, but if it stops turning, it produces no current and if it produces no current, the led would not be a load and the generator would be free to turn, so it automatically finds its "sweet spot" for a particular LED load.
If the led was removed it would fall as fast as its mechanical resistance would allow.
If the led was shorted the fall of the gravity load would be slowest.
In every case, the motor always turns.
Very Cool design.
I hope some philanthropist looking for a tax write off starts sending them out to where they are most needed.
pfff I was just gonna say that ...;)
Physics is cool! The only weak link in that system is the belt. I made my living changing belts like that. They turn into chewing gum in a few years.
Thanks for this explanation but I can't quite wrap my head around how the voltage limit of an LED makes the motor turn more slowly?
I do some very very basic (electronic) prototyping and if I don't add a resistor, the LED will draw power until it burns out.
Do you have any sources I can use to learn how your explanation works?
Things like this restore my faith in humanity, but then I turn on the news and it quickly goes away.
+Awaken the Evil That's why I quit watching the news. Ignore it and it effectively doesn't exist. Nothing they ever talk about on the news ACTUALLY matters, anyway.
+Awaken the Evil The solution is simple: don't turn on the news.
+Awaken the Evil Don't watch the news (Y)
Just follow some news outlets, not fox news and the likes, who just put out what people want to hear, why do you think they have hot woman reporting all the time lol IF you follow them on Facebook or wherever you can click on the article if you want to read it
+Awaken the Evil There is actually less violence than in past times.
the light is not exactly powered by gravity. It is powered by your muscle when you raise the weight. The falling weight is just a store of energy that was created by the person
+ambrous shut uuuuuuup
+ambrous Well TECHNICALLY muscles are made of star stuff, and the sun is a star, so really it's solar powered. :)
+ambrous but if there wasn't any gravity it wouldn't fall and it wouldn't create any power to power the light so gravity wins (gravity falls to be more accurate )
+ambrous thanks i was actually a bit confused
yes it is the potential energy
Great video! But I feel like you failed to explain why/how an LED light can prevent the generator from moving regardless of how much weight is applied. That seems like the most fundamental part of this invention!
+karmakazi219 There's a video that explains that which will be uploaded to the shell channel shortly
+SmarterEveryDay The Shell Oil channel? Interesting. Thank you!
In short: A LED has a sufficient resistance so the motor doesnt get shorted. As soon as the voltage of the motor gets too high (happens when it goes faster), the LED loses resistance and is therefore getting closer to a short.
Now, you have to know that a generator that is shorted will stop immediatly. in this case, it will just be like braking a car. it limits the speed at which it can go.
You're not explaining how or why a generator that is shorted 'will stop immediately' therefore I'm no closer to understanding the answer to the question than before you made that reply.
*****
In short, it works like a watermill: If you hang something up to it, as in an actual load, it spins slower. Now, a short circuit is the equivalent of trying to power a huge city from a small little river that is hardly half a foot deep. It simply will never spin.
To explain how the generator works:
Electricity is generated by a magnetic field that is spinning around copper coils.
The magnetic field that the copper itself generates (which increases the higher the current is you pull from it) counteracts the spinning motion. So, a short circuit (which means maximum current) will simply stop the generator.
The LED is not a short circuit though, so it will simply counteract its motion just enough for the LED.
I love how their faces lit up for a split second when you said "that's genius"

+doombringer6s Crawlspace habits? I guess with the layout of the shop, he probably got that habit after bumping in others a few times, spilling the content of his mug everywhere. By walking with his mug behind his back, he increases the time he has before bumping in someone as well as reduce the movement of the mug by the factor of energy transfer not reaching fully down his arms, reducing spillage. (Sorry if that doesn't make much sense, I'm not sure how to word it correctly for it to actually make sense.)
It's amazing how simple this is, yet only just been developed. Got to love engineering!
+TheRecreationProject it is not that simple, these gears needed some serious calculations and the manufacturing process might be expensive so you need millions of customers to make it affordable taking into account the main objective is to provide underdeveloped countries like Africa with this product.
+Luis Fernando They didn't need serious calculation. They required the same level of calculation that you would perform in any base level physics course at a university. The process mimics that of old grandfather clocks. Would it take time to perform the calculations, yes. Are the calculations difficult or highly advanced, not as much.
+TheRecreationProject I know right? It seems like this would have been low hanging fruit.. something we did ages ago!
+SmarterEveryDay Why hasn't it then? The only thing I can think of is that LEDs are relatively new and other light bulbs wouldn't have been very practical.
+Steve Balsamo Because most people have access to batteries and the electrical grid. Batteries are far more convenient (and mobile!), and the electrical grid is far more convenient, cheaper, and powerful.
We have being turning gravity into light for years in hydro plants...
@yeah I'm John Assal Well Solar Fusion only exists because gravity exists so...
@yeah I'm John Assal Haha
Even so, little devices like this make for a nice, practical invention. Maybe with a big enough gravity load (weight) we could create a nice general-purpose generator.
@@ORagnar i dont think its scaleability is practical.
@@Ian-ie3hy Maybe it can work as a light house of sorts...

Connect a bunch of these to a single weight that travels down a deep well and you can light up an entire small village for a couple of hours.
+Neumah Or a single bigger generator?
+Neumah Or build 1 wind turbine.
+Deline Needs wind, gravity is more consistent.
+attrem Also needs a large space. This is tiny in comparison.
+Neumah Muscle isn't a great way to make electricity beyond a dim one-room light.
"Click here to see how Shell used to drill arctic for oil and now tries to look good saying they support renewable energy"

+Smadonno "...Whilst still drilling for oil in the arctic".
+Smadonno Shell and any other company should be given the opportunity to explore new and more ethical paths, like this gravity light. They shouldn't be dismissed as irredeemable just because they are in oil right now.
+Tristan Patterson actually you can live on 100% renewable... and its not that much more expensive, a home can easily run on renewable... in fact my electricity and gas only come from renewable sources.
You thought it was gravity, but it was me, muscle power!
Yeah I was thinking about that
This would be a neat item to even charge your devices.
Which is also a challenge to do at night in developing nations.
+SmarterEveryDay or any airport.
+KiddsockTV Seems impractical. Gravity isn't really a good way to store energy, since it just takes so much stuff so high up to store any real amount of energy.
To put this in perspective, their 12.5 kg/27.5 lb weight would need to be 300m/1000 ft in the air to have enough energy to charge a current gen iphone, and that's assuming perfect efficiency.
Really, this solution is great to provide some basic lighting, which requires incredibly small amounts of power with LEDs, and there are a few other applications where this would be great, but for charging something like your phone and so on? No.
+seigeengine
*SO WHAT'S THE PROBLEM !?*
When the weight eventually reaches the ground - you just hoist the weight back up again - unless you're super lazy - people in 3rd world countries don't have time to be lazy - quit being so negative.
VL VIDEOS The problem is if you used this set up, you'd need to haul the bag up a couple hundred times to charge your cellphone.
Also, point here... it would be more efficient and more compact to drive the system yourself rather than going through the intermediary of storing energy against gravity, and then using that.
This is actually along the lines of what people are proposing as a solution to storing solar power on mass.
Because lithium batteries can only hold so energy and they lose energy too fast for large reservoirs. Using solar power to lift an object while its getting energy and letting the object fall when there is no more sun gives you the ability to store energy theoretically until gravity stops working or something physically brakes.
The trick is translating solar energy into lifting energy efficiently.
Sean Peery Actually gravity is already used as storage as pumped hydro-power
Sean Peery oh and their efficiency is around 70-80%
matucha123 Thank you.
This is not practical. A small solar farm with an output of 10 megawatt will need to store 180 billion joules (10 hour day, half of the energy is stored for the night). You will need to lift an anchor that weighs 1 billion ton to 180 meters. If iron is used, it will cost around $88 billion not accounting for the labor, structure, and lifting mechanism.
I think you've made a mistake here: 1 J is 1 Nm. 1 N is approximately the weight of 0.1 kg under Earth gravity. So you don't have to lift 1 billion tons 180 m but only 1 billion times 0.1 kg or 100,000 tons. The hydropower plant near the town where I grew up has a head of more than 800 meters, so to store 180GJ you would have to pump up less than 22500 m³ of water. Doesn't sound that bad. (And in fact using reservoir power stations to store excess energy has been done since at least the 1960s.)
This is very clever, but can you turn light into gravity?
All energy exerts a gravitational force so yes
pineapplepenumbra yes. Cody's Lab does an experiment where he does just that.
Billy Dengel
Thanks, I'll look it up.
solar light heat up water -> vapor go up and fall
Believe it or not, yes. If you were to take a powerful enough array of converging laser beams focusing on a single point, they will form a black hole.
_Exactly, precisely, Exactly_
Precisely. ;)
Absolutely 🤣
Indeed
it's a human powered light... that uses gravity and potential energy as a medium to store the energy, like a windup toy that uses a spring instead.
Grip Limit exactly. A humen still has to hoist the weight in position. That uses humen energy.
Still, technically it's the gravity that moves/pull the weight. We usually call a windup toys a "spring powered" toy, just like this a "gravity powered" lamp.
Immanuel Herman sure those examples are how we define the way we store the energy, but we (humans) still put the energy into it. unlike your cell phone that you plug into an external power source, or buying batteries for a flashlight.
And humans are food-powered. Which is sun-powered. So I guess it's a fusion-powered light ;-)
Diego C. you are correct. almost all energy on the surface of this planet comes from that big ball of plasma in the sky.

What are the plastic gears made from? What is the plastic casing made from?
Alternative energy doesn't hurt fossil fuel companies. They are diversifying their products since the fossil fuel they're relying on is not permanent anyway. In fact, it give them more initiative if they want create context, the "switching" point on the market when their stored resources are running out.
i am sure you have helped a lot more poor people than this light made with Shell's money will ever help. /s
This video just made a bunch of people dumber (every day) by making them think gravity was some form of energy which could be harvested.
+Joshua Pearce you can't be serious.
i thought they teached potential energy in like pre-school.
hydroelectric plants work on the same principle. store potential energy and harvest it slowly.
+Joshua Pearce Yeah, thanks Shell!
***** Yes, potential energy is what's at work here. Gravity is not consumed during this process. It would be almost just as wrong to say it's turning bags of sand (or whatever the weights are) into light.
And the title is "Turning gravity into light", not "A machine that produces light as a result of gravity."
+Joshua Pearce Your comment should be titled "Turning a douchebag into a comment."
DragonTech Assuming I'm the douchebag, I'm still here, so I was not turned into a comment.
BRILLIANT! I still don't understand how the LED prevents it from spinning faster, why wouldn't the weight just fall faster and over volt the LED?
Agreed. Just at the most interesting bit (as a student of physics) - the mechanism for the linear decrease in GPE - his explanation is "Once the generator turns up to a certain speed and that voltage limit is reached, the LED won't let it turn any faster." Other than the circuitry having a threshold on V_emf, that is no explanation whatsoever!! *How* does the LED not let it turn faster?! That's the crux of the matter. Just stating it happens doesn't explain it, Mr +SmarterEveryDay. As such, I would very much like to see a supplementary video explaining this key (missing) explanatory step. Thank you for reading this (if you did). All the best.
PS This is an amazingly simple concept. Why has no one done it before?? As the potential energy comes from lifting an object (i.e. GPE), I'm thinking about the applications to a gym - storing electrical energy that can be used for any number of appliances one could connect to it.
((Proof of concept: Have several GravityLights in a row, lift many objects and have a larger amount of light! But then imagine creating a device where one can lift ONE object several times to store that same amount of total GPE, which can be used for whatever purpose and when the user chooses.
I also watched your video on the ARED, so maybe those guys would have some idea how to go about it.))
Electrical resistance I would assume.
bossmanham
Yeah it makes sense to say it, but when you ask yourself why it wouldn't just over volt the LED I can't seem to see any reason why it wouldn't. For instance if I had a hand crank generator hooked up to a tiny light bulb, why would it be impossible to just crank it faster until the bulb burned out?
95TurboSol Think of it like water going through a hose. The certain electrical connection, in this case the LED, can only fit so many electrons through at once. Just like a hose can only fit so many water molecules through at once.
Not 100% physically accurate, but pretty close.
bossmanham
In theory it sounds right, however it's definitely not physically impossible to fit so many electrons through something that it just melts the medium that it's flowing through because of heat. For instance, if you took a tiny string and flung it up to a high voltage power line, it would kill you even though the string is tiny, and back to the LED case, I know for sure it's possible to send enough power through an LED to burn it out, so why wouldn't it do that instead?
Is no one else concerned that this legend was alone in the Amazon rainforest AT NIGHT, ALONE?!

+Blu3Emperor I love it. It's like christmas present in advance! :D
+santiago Marroquin also the shots of awe uploaded a new video
Just watched "the engineer guy" literally before this video and they both talk about gears... I was mind blown!
Wait, the generator is the thing that prevents the bag from falling down so fast? The LED won't let the generator turn faster, I get that, but HOW?
+CheeseWithMold Yeah, I wish they'd explain that in more detail.
+CheeseWithMold It's magic, don't question it
+CheeseWithMold The LED sends a back current that causes the motor to short out and lock magnetically until the current drops again, at least I think so. So really the weight is jittering really really fast as the motor locks and unlocks
+CheeseWithMold I'm confused by this too. If you were to switch off the light, the bag would stop dropping? I'd love if you could explain this, Destin.
+CheeseWithMold +jatzy
From the resistance of the LED, voltage=current*resistance.
Since LED's only run at a certain voltage, the resistance and therefore the current of the LED change to achieve that voltage. Think of it as a funnel, if you pour sand into the funnel it will slowly drain out at a constant speed. decrease the size of the hole at the bottom (increase the resistance) the sand will flow through slower (current). Pretty much if the resistance increases, the current decreases causing the voltage to be steady state. So to keep the voltage constant, the current and resistance is changing (internal property of the led) depending on how much mass is in the bag. hope that helps explain it to you! if not feel free to ask away.
Now that is freak'n genius! The secret societies are thinking, "Now, how do we monetize gravity? Moo ha ha haaaa....!" ;-)
At 70 bucks a pop they already have...

😂😂😂😂😂😂
This guy always presents very interesting but offbeat subjects.
+SmarterEveryDay can you make a video explaining how the electrical energy of the LED limits the mechanical energy created by the gears and weight. That blows my minds and completely don't see how that works.
+Tim Fevens I also want this. Does the led have a current limiting resistor? or is the generator not able to produce too much current because of mechanical resistance?
+kwanarchive I know that much but my problem is Why? I don't understand why/how an LED emitting light slows down physical matter.
+Tim Fevens I have the same question, too. LEDs do consume a fixed amount of voltage, but they usually have current-limiting resistors, which will consume as much voltage as you throw at them. (Wires are just low value resistors as well.) Without them, more voltage will increase the current , heating the wire and/or blowing the LED. But either way, I really don't see how the electrical characteristics slow the physical movement of the weight. Are you sure it doesn't just fall at a slow rate because of the friction in the gearing? What happens if you replace the led with just a resistor? Is Destin saying the weight would fall more quickly?
+Tim Fevens As an EE student, my best guess is that either the dc motor they are using has a speed limiter based on the output voltage (i.e. a system that won't let the motor over volt) or there is additional circuitry involved in that process. I don't actually have that much experience with motors atm, but the thing about the LED, and diodes in general, is that they have their set voltage limit that is used for many different applications. Look up zener diodes for example, where the breakdown voltage is specified by design. Hope I got close and was at least a little helpful!
+Chris Godley I have another guess.
I think, this is pretty simple to build. All you need is a zener diode (controls the voltage the flowing energy) and an electric generator.
The generator can act like a motor, so it slows down when its energy is not used. There's the gravity on one side and the electricity powering (yes, powering) the generator on the other side.
Better explained by an electric motor: The faster a motor runs, the more electricity it will produce (yes, produce). A generator on the other hand, will slow down if it doesn't power anything and the electricity/electrons search(es) the easiest path on their way.
And this is used in this contraption. I am pretty sure that they do everything to control the exact voltage of the diode as a slight increase of the voltage causes an immensive rise of the current. And this would cause a lot of lost energy as well as a decreased lifetime.
*I'm so poor that I don't have access to gravity.*

That's some awesome engineering right there, and reality at the already low cost i could see everyday consumers covering the cost to tool up for mass production to provide them basically free to people in need while the market covers rest.
These sort of Ideas is why we should have more Co-Ops so that it can be shared around instead of having to do it all yourself.
I foresee a gravity shortage by 2025! This is great, I have spent time in countries where this would not only be life changing but life saving!
Reduced gravity will cause the seas to rise and polar bears to migrate into cities.
yes but we will definitely start flying on earth. Its gonna be a great achievement.
Technically, you aren't powering by gravity, you are powering by food since the energy input comes from lifting the weight.
Gas power comes from solar energy stored by plants and microorganism that became petroleum. So, petrol cars are solar powered.

I absolutely love this! This is a beautiful feat of engineering. Not only does this eliminate the use of harmful resources, it can be used anywhere, at any point in time by any person on earth. This is such a clever design, it is blowing my mind how simplistic it is. Thank you so much for sharing this.
Technically it's just harnessing your body's energy; the work done in lifting the sac results in the gravitational potential energy which powers the lamp.
So in some ways it's just like a hand-crank lamp, except you do all the work required in a matter of seconds by lifting something heavy. 😛
Plus there is no battery
could you have a large scale version of this power a house? use a car jack-like tool to lift a very large weight high up, and reset it every morning as part of your chores?
excuse my possible ignorance.
good idea
and connect it through a gearbox to i dont know may be your treadmill. so that 2 times exercising(morning and evening) may full up all the weights and power the lights for the nex day.
Good idea, if it was on a large scale, the generator must power a battery to power a thing to re lift the weights thought, that is the only challenge.
Sounds like the clock.
I can imagine this being applied for a giant battery.
I wonder if the energy generated can be used to lift the weight back up via a motor or something, and still manage to produce more than it wastes :O
it cant
no perpetual motion, my friend
No one has attempted to convert gravity into light..
The sun: *Im a joke to you?*
Hi Destin, my 5yo son would like to say; "I kinda like the light because I want to see, and I like the video."
I play videos for my son at bedtime and I watch to see which of them capture his attention spark his imagination. Smarter every day is his favorite, he has been watching your videos for about a year now with no signs of loosing interest. Thank you Destin for opening his mind to bigger ideas.
Give me a minute to assess the "gravity" of this situation... This is what we've all been "weighting" for.... I have seen the light..🤔🤯😅😂🤣
You say gravity.. fair enough.
I say it is a inequationated theory on a yet unexplained downward force.
Nice of you to weigh in on the topic, WC.
@@EnlightenedTurtle Quantum Physics explains this downward/negative force gracefully without gravity, and CERN scientists confirm on their home website that they've never found the graviton supposedly applying this force...
Heavy man. Weighs me down.
@@MikhalisBramouell lol what you lying for... it is theory not fact.
Like literally 100% theory!
This idea doesn't need the hard shell, it shells itself. Sorry, couldn't resist.
LOL
Who would have thought Shell would pedal an invention that used renewable energy in the place of burning a filthy hazardous fossil fuel. The sweet delicious irony.
Still can't believe I missed you when you were in my home town (Salisbury)! :(
It's been a long time since I've enjoyed a commercial so much, thank you!
I wonder how easy it is to replace the belt? As rubber belts get old, the rubber cracks and they break.
+freesk8 Awesome product! I hope they sell millions.
+freesk8 I'm sure the bearing will break faster due to the high stress it has to withstand. Also, the plastic won't last for decades. After 5-10 years the device will be broken, but it shouldn't be too expensive to build.
+freesk8 Good question; fortunately in several developing countries in South America and Africa they have acres of rubber trees that they sell to developed countries. So really all they have to do is continue to do what their doing but keep a little more of it for their little light belts.
+freesk8 third world country have well developed repair shops that can fix most simple things, it did not look that complicated
*****
have you been in a third world country, there is a loooooooooot of rubber and plastic(it is cheap). their is no organized way to get rid of the stuff
There are so many great technologies that can make the world run efficiently on minimal power, but when we talk about climate change it always shifts to mega projects instead of every house having their own systems. If someone suggested we power our lights using gravity, planners would design a gigantic skyscraper-sized version to power thousands of homes at a cost and timeline that doesn't make any sense compared to building things like this into all homes and buildings. Why don't I have an exercise bike that is raising a heavy weight to the top of my house that I can use for powering the lights? Even a small windmill with proper gearing could do all the heavy lifting for those who don't want to exercise. This is a simple way of storing renewable energy, e.g. when you have wind/sun it raises the weights and generates potential energy for when the wind stop / sun goes down.
Actually, the eco-terrorists would file suit to stop the production because some small amount of petroleum is consumed in the materials and processes. Don't you know that oil is pure evil? Oil becomes the daemon Satan in their religion of environmentalism.
We should all do it but in many countrys they now taxe you or make you pay to use the sun and if you are a good nieghborg and share for free they put you in jail...
Humm some big corporations are running this earth
Kids in Africa could have eaten that gravity!!
Well the potential energy does come from the food they eat.
What food?
Felipe Hdez gravity
I bought one for my son for his birthday a while back. He loves it better than any other gift I have ever bought him. We regularly feed treats to our cats that come in plastic canisters. Using the canisters, we filled them with pea gravel we got at Lowes. We don't have to worry about spilling the gravel or it wearing through the bag. Finally, something that really works. I wish this guy would reinvent the toilet flushing kits. It would save billions of gallons of water a year.
wtf what are you doing in the Amazon...
Rich people travel to make YT videos.

Lets go to africa and sell gravity so they can use these lamps
Sure they would love to buy it from Shell in the delta of Niger river. Shell has a lot of friends there... and a little spill of oil.
The thing is to have open and free blueprints of the device and make it from recycled materials. That's the way you do it for everyone.
I'll wait to see how this is not a image washing campaign.
Short: It's a good idea, but evil corporation funding. Not much hope
This stuff is so costly that with that money, those Africans can eat for a month
Ah, capitalism.

This was an awsome one i love this gravity light a great emergency light for anyone anywhere. Thank you.
You have so many great videos!
I can't stress that enough, not even with bold, italics, exclamation marks, and all caps!
Thank you!
"...and we will see if we can come up with any bright ideas". He said it and turned on the light.
Guys, he made a pun.
Everyone wastes energy on oil and gas companies instead of helping everyone find a solution for the future. This video is so valuable
Great video, right. A few supposed platitudes: It is NOT necessary to FIND a solution. Everyone can see and feel this solution every day - sun and wind (energy storage and power lines are not witchcraft either). What one should do has been known for decades.
Laziness and fear of change prevent the urgently needed implementation (not to mention lobbyism, greed, idiots denying anthropogenic climate change etc.).
That is amazing! I never knew this even existed. That's awesome for areas prone to natural disasters. I'm going to have to get one to add to my hurricane preparedness kit. 😊
Hi Destin,i m just want to say you are a great human being that this planet earth need more like you.I m not much educated but is people like you that inspire me to move on and see the world differently,thanks

Wow, what an amazing inve tion.. thank you for sharing this with us.. this is why i love watching your videos, i learn something new every time from em
My favorite gravity based invention that ive seen recently is the simple rail cars they use excess renewable energy to power the car up a hill. Then when they have low energy times, Cloudy, no wind etc. They set the rail cars off down the hill and use the break system to generate electricity. Kinetic batteries. So simple but brilliant.
the co founder of gravity light is similiar to the young professor x in x-men
it's just my oppinion
Or Loki
was searching if someone thought the same XD
10 kg lifted 1 meter up gives you 100J or ~0.02778 Wh of energy storage. That's ridiculously bad. One 18650 lithium-ion cell holds about 10 Wh for a cost of about $3. Enough to continuously power that pitiful light for about a week. Small solar panels cost about $1 per watt. So, fits into $10 budget easily, even if you make it several times brighter.
Have you calculated the energy it takes to make this verses the energy to make the others? ROI on this purchase keeps going up the longer it is used.
R Kimpel wtf does your gibberish mean?
But then you have to maintain and protect (from nature and thieves) the solar panel. And that's more parts that can break and pieces to the puzzle. So if something is wrong, do they buy the whole system again since they don't know how to fix it? With this, it's probably being donated to them and if it breaks, so what, they go back to lamps or buy a new one. Different solutions for different situations, this is just one more solution to choose from.
Andrew Jones it would be much tougher and have a much-much longer life (on the order of 10 years). Yes, it might be more appealing to the thieves, but only by being actually useful.
The problem is, batteries degrade in time. In a year of continuous use and recharge, the led lamp would probably be on half of the time.
This is really a cool idea. Although, i don't get the voltage limit thing. How does it stop the generator from turning faster? Does anyone know a good article or something where this is explained well?
When the load on a generator is increased (that's the sharply rising current graph in the video) it creates something called "counter-torque' in the generator, an electromagnetic force opposing the rotation of the generator - effectively acting as a brake.
Norman Higgs
Ah, thank you. Now I know what I have to search for. Sounds really fascinating. :)
this is nothing new i can assure you that. people have been powering light off of gravity aka water reseviors/ dams .. nothing new here, it only new to him because he has nothing else to report
Chris Prime
By this logic, there was nothing new in the last 7 decades or so, as every new technology was derived or inherited from already existing technologies.
If not mistaken the "votlage limit" mentioned by Destin is about the forward voltage of an LED (diode) where at certain point of voltage increment, the diode will allow a lot of current through, essentially loading the motor a lot more, slowing the motor down like a short circuit.
I think the "counter-torque“ mentioned by Norman is one of the effects but only obvious when there is little to no load.
As someone from Salisbury I did not expect my sleepy little city to pop up the very first day I'm learning about Smarter Every Day! Super cool
Gravity is ancient technology.
Probably invented by China in ancient times.
Or Switzerland.
that's as far as you think it is?
much before that there were extraordinary inventions,
check about how the pyramids are built from the insides...
Hi guys, look at the history of ancient Europe before the renaissance, when the caliph Harun Al Rashid sent a watch as a gift to the European King Charlemagne, the clock that every hour tolled, supposedly by Charlemagne, that inside the clock there's a satan and the spirit in it. So, when the clock's tolling, making people who watched it became frightened,
Just like the first case, they thought there were a satans inside the clock that automatically tolling for its every hour.....
Just reminding this history, so then we'll know who is the inventor and where the technology using gravity energy's came from....
@@louismargareth1960 Do you have a reference to this story?
@@jeanbaptiste3470 go to the library and look at the history of habsburg dynasty....
Charlemagne, the king of frank, was considered to be the king, he was the first guy who define united Europe after the fall of Rome, in the 4th century AD
And He ruled from 768 to 814 AD Pope Leo III, bestowed himself as the Augustus Imperator in Rome in 800 AD
That was the caliph harun arrasyid era....
China found gravity buried in the Australian outback when China took over ownership of Australia.The traditional owners of Australia are trying to get gravity back as they think it's an ancient spirit from the dreamtime...
Literally tons of ways of doing things, but i never thought about gravity. Dam!
was that suposed to be a pun
neither the clock or the light is powered by gravity. they are both powered by human beings doing work by lifting weight.
No, the direct work is done by gravitational pull where potential energy is converted into kenetic then into electricity. otherwise by your logic the it is powered by the sun.
And you're BOTH correct. Human work is put into lifting a mass to a height where it obtains potential energy. The system of which it is part is then initiated and the human input of potential energy is then used as kinetic energy because the mass is attracted to the Earth due to gravity. It's all about energy. Calling it a 'gravity' powered system is a misnomer, although gravity induces the potential energy.
[And as a side note: Gravity is present in all energy, not being a property of only matter. If there is energy, there is gravity. The more energy within a conformation, the more gravity. I don't know why this concept is hard to grasp except for the fact that we don't have instruments capable of measuring the gravity of an EM wave/photon. But we know this is the case because EM radiation is attracted to black holes.]
Nakruf SteelCore so, no people needed? just gravity?
Eric Cameron Dummy ;:D , What i am saying is, a system where a human is part of the system does not mean the system is soley based on that. We could have some machie doing the liftwork i.e giving it potential energy but then we don't say the energy is directly converted from mechanical to light. There are other procesies that are in place where energy loss becomes greater.
And human beings are converting the chemical energy from foods to the kinetic energy of pulling the weights up. Foods get chemical energy from solar energy. So, you can say, it's solar energy that's running the clock and powering the light.
I bought 2!! They are quite rugged and perform really well. Surprisingly heavy and built to last which is not projected in the video.
Interesting! In a certain way, isn't the sun turning gravity into light as well, though ?
Viktor Hofer gravity only triggers the fusion. It's not where the heat and light of the sun comes from. Like if you shoot a gun, when you pull the trigger, the chemical potential energy stored in the gunpowder releases into combustion energy which pushes the bullet out of the gun. The energy of the bullet (heat and light from the sun) didn't come from the energy of you pulling the trigger (gravity) but rather the energy of the combustible inside the gun (mass of the sun, which is its actual source of energy).
dam. I would hate to be in space with that.
Zadott Erazo you could pull it down
to much effort
bungee cord
Easy, centrifugal force!
Now you only have to get those lamps to africa
+dxxPacmanxxb Turns out they thought of that and set up local production. Seems they'll actually be an export. Check out the website.
***** i like that
Call of duty care package... Stuffed to the brim with these things.
after the you get a 4 kills streak whilst fighting in the civilwar
This should have 1.8 billion likes. My mind is blown by such a seemingly simple solution!
Wouldn’t it be better if it just recharged batteries so then you could power lights or other things at the same time instead of one light that needs to be constantly reset.
Watch from 06:41… they talk something about using a connector to redirect the power to another appliance.
Sreenikethan I. Thanks for pointing that out. I guess I wasn’t paying attention. 👍
That is truly awesome. Have they made ground in making it cheap and distributable to the 3rd world? That is the common point of failure.
Of course not. No money to made there. Why would they.
The whole "they did it because of the poor" is just advertisement.
They cost less than 10$ so even a poor family in Africa could afford this
David Burke but the question remains: do they have the intelligence, self-awareness and lack of apathy to actually save $10 and buy one? Let me help you out with the answer: no. The problem here is and has always been the people we're trying to help and not a lack of us coming up with new, fancy ideas and tech.
79.99? Well there goes the chance for this to actually do something. No developed country would ever purchase any of these, and no poor country could ever afford these. At that price, you could buy a portable lamp and enough batteries to never warrant buying these at all.
David Burke Yeah I saw another company selling these for $60.
Gah!!! I had this idea in high school in 1987!!! timing is everything
MrSmackdab Gravity was only invented in 1992.
Dave Ravenswood yeah, before Isaac Newton invented it
issac newton was Fig's gggrandfather.
This is Insanely Genius...
Thank you so much for this...
I loved it...
So... can africa afford it?
Yeah this was my concern too. Not so much getting them over there, but actually keeping them running. It'd be interesting to share these methods with people in Africa and allow them to develop similar devices with local resources.
+Insane CoolAid I just don't see how people living out in nowhere are even going to get access to these things let alone be able to afford them. If you live in a house made out of mud and straw with no electricity, far away from "civilization", then you might not even have money to begin with.
+huldu the same way they get their other supplies like their kerosene or whatever... there will be some sort of market system in place, be it a local market place or mobile traders or whatever
+Michael Edmond But getting kerosene is quite a bit different than little plastic gears or a led. Everything is in place for them to be able to get kerosene and has been for quite a while. There will need to be a huge investment push to get this out there and then easy ways to distribute the replacement parts. It's an amazing idea and maybe everything is much simpler than I'm imagining, I'm no expert. Hopefully it is.
Chad Worthy they are.. Their manufacturing plant is out there and they are training people out there to make and repair them, also I think their idea is to engineer them so they are not likely to break, and in the video he strips one down rather quickly too. And who is to say the kerosene salesman can't also sell these too!
It's not light from gravity. It's just the energy (from your muscles) you use to raise a weight and releasing it over time.
akeslav that's technically true, but following this line of logic.
The energy your muscles create come from the chemical reactions inside your body.
Those come from the food you eat, the food is created through the use of energy and/or mass from the sun or nutrients (which ultimately have their trace elements come from stars)
Stars trace their elements from previous stars, and keep going back until you reach the big bang.
So everything you do is Big Bang powered.
And what are your muscles pulling against? . . . . Gravity. When you lift the rocks you are storing a form of mechanical energy (potential). As the rocks slowly lower to their original height, the conversion from mechanical to electrical energy via the gears and electromagnetic generator is in progress with the end result being light. Gravity is the source of the energy. If you were in a micro-gravity (environment) like Earth orbit and you performed exactly the same motions, there would be NO LIGHT because there is NO GRAVITY, so no potential energy was stored. Gravity IS the root energy source.
Oh, this is just genius ! Thank you for sharing. This is a game changer!
This is Amazing! Great job thinking outside the box GravityLight! You just helped persons save goods or money on fuel costs, helped preserve the health of their lungs, and possibly their eyes as well.. and... helped a family with getting homework/sewing/other housework things needing done after sundown! Proud of you guys!
it's very old trick, potential energy into kinetic energy that will give working to gearbox and it's turned generators and light started to glow, every hydroelectricity dam used this technology
Yes
They used the same concept but technology differs.
if they are using uphill roller series setup then worldwide pollution solution become easy because we are using only gravity as a fuels which is totally free energy and pollution free, whole world scientist are welcome to discussed over it with me, i spread this concept world wide already from many years on various platforms
weird that an oil company funded an alternative to oil
Made of plastic, which is made of oil
+Emil Carr Helps them look progressive. The P.R. is worth more to them than whatever small profit they would make off of kerosene lamps in 3rd world countries.
+Emil Carr Oil companies aren't the source of all evil that you think they are.
VintageLJ Nobody said that they thought that.
+Emil Carr As already said the PR is probably worth a lot, but most oil companies are constantly looking at and investigating alternative power. They are not in the oil business because they are evil, they are in it to make money. If they can find an alternative energy source that can make them more money they will certainly invest in it. This gravity light is not something they are going to make massive amounts of money from directly, but it gives great PR.
No scripture reference at the end?
I was waiting for it, too!
Yeah I was waiting - and a little disappointed :)
+wallyhall might be because the video was sponsored... Perhaps they put some restrictions in place.
+Craig Gilbreath It seemed like an easy one to reference too. Matthew 5:16
I was thinking John 8:12
It's a really good idea ok 4 years old now but still it was a really good idea, the only problem I envisage is over time the rubber band will deteriorate, ok it would take years, so you would get your monies worth out of the device but still if you kept it for emergencies you could to use it and find the rubber band had deteriorated in which case you would then have no light.
That's the problem with having things that use rubber bands as some kind of drive, the band deteriorates over time, stretches crumbles or what ever then it's useless.
But it's a really good idea.
@flitsies Great point. I have a 400 cd wurlitzer-like player that no longer functions because of a rubber tube around two pullies. Stupid little part that probably costs 5 cents. I haven't figured out yet how to fix it. It got old and stretched.
