I believe in what you are doing. There are tons of us who love your work. Please never stop!
Thank you for the nice comment, working on the extra mirrors.
i guess Im randomly asking but does anybody know of a tool to get back into an instagram account??
I was stupid lost my login password. I would appreciate any assistance you can offer me.
@Gianni Isaac instablaster =)
@Mauricio Alfonso thanks for your reply. I found the site through google and Im in the hacking process now.
Seems to take quite some time so I will get back to you later with my results.
@Mauricio Alfonso It did the trick and I finally got access to my account again. Im so happy!
Thanks so much you saved my account !
thanks for the tip mate. I'd not known that, and considering how counter-intuitive it is, you've probably saved people a lot of time here.
Rojas, you are the man! Thank you for what you are teaching people.
Excellent ! so simple, so cheap and so efficient !!
Thank you for sharing, it looks like you made a very cost effective way to make parabolic reflectors!
I'm fascinated with your tracking system on the trailer plan, and I am thinking of using something similar to power an absorption chiller to cool my home in the desert. It is insane here in Arizona that we are using grid (or fossil fuel) energy for cooling!
Keep up the great play/"work", always stay safe from those sun beams et. al.!
Great idea! Solar trailers are a brilliant idea! Thanks for another video!
Hope all is good with your health and keep the sun video's coming I really like em and learn alot.
I have learned a lot from Dan ... i will have something to show hopefully by summer
Thank you Tom.
Hey! Nice hair cut man!! Love the parabolic mirror videos!!
Looks good! Thanks for sharing!!!
Welcome back! Thanks for sharing your update.
Regarding the array table, wouldn't you need two-axis movement to track the sun?
Hi Tom,
Thank you for the nice comment. The dual axis will be required more in the summer than winter but rear legs of the easel stands will have rollers and one screw drive to adjust them. May be complex or very simple, not sure yet as I have not gotten that far. I am guessing the power may be better during the summer for an AM - PM time period vs 12 noon as the beams would be a bit linear to the target when the sun is directly overhead.
A few decades ago I was working on a 2 axis tracking system that worked only with the magnified heat of the sun falling onto bi-metal springs, expanding in the heat until aligned with the sun in each direction again.
Bro ur so talented person..
Amazing. I wonder if you could use a similar setup using scrap mylar as a mold. Just pull a vacumn on it, then layer it with fiberglass and resin, then lay new mylar on top of the resin. Just keep the vacumn on it until it dries, and it seems you would end up with a permanent parabolic mirror. Probably things I'm not considering, but just an idea.
Hey Dan great vid but I was wondering if we could get an update on that huge Aquaponics setup that you had started on a while ago. Thanks for your time brother.
Hey what you doing is just awesome , have you tried to boil water and use the stream to make electricity??
Apologies for the delayed comment, but as I explore solar power I can't help but wonder if perhaps you can apply a shellac coating to the surface of the mylar to create a rigid form which would then no longer need the vacuum interface to retain its focal point? Perhaps you can even create the first form with shellac on the top surface, then use it as a mold for other reflectors, where the shellac is applied to the bottom surface then allowed to dry? Well done! Thank you for sharing!
I love your videos.. how much enthalpy are you getting from them mirrors? how about transfering the energy to a steam boiler?
Could you please make a video about parabolic mirrors and pyrolysis?
Using the focused sunheat turn plastic into fuel?
i have built something similar to this, you should try spraying the inside of the mylar with resin before you apply the vacuum
If you were in the Mojave Desert, what would be the first experiment you'd want to try? Temperatures from fresnel lenses vs. in Florida? mirror work? parabolic mylar? or??? Thank you. I purchased a couple Fresnel lenses many years ago. ❤
I want you to try the paint called the mirror in the can
Lovely build. For an easy Sun tracker just use cross-wired electric motors, each powered by a small solar panel, they automatically face the Sun.
Can u give instructions on how to apply the resin to convert linear lenses to spot ones
I found you folks recently and really like your videos.
How about a solar heated waffle iron?
I thought of it because my friend gave me some homemade pizzelles (cookies).
Also I have a Connect for Manta black paint I would love to see you make an aluminum can home heating device
Live your work! Are you familiar with plastic pyrolysis? Someone needs to make a plant powered by a fresnel lense or parabolic mirrors. If anyone can do it you can! It's pretty simple compared to what your capable of and you already have the lenses. Turning mixed plastic garbage into fuel only using the sun would be incredible!
Will Mylar reflect 99% of UV, Visible light and Infrared rays falling on it? Is it possible to make the focused light from one concave mirror go into a cubical box via a small hole? Could you please make a video on it. Thanks
So going to build this.
GREENPOWERSCIENCE
I was wondering does a fresnel lense in front of a solar panel increase efficiency at all or a parabolic dish array.
I am not sure if you alrwady covered this before or not?
I mean I guess it's cool, but is there a practical reason to build a sun tracking parabolic mirror array? like to focus a lot of light onto a small but very high yield solar panel or heat a large amount of water very hot for some reason?
If you have a parabolic dish but in the middle you have a hole and on the Focal point you have a straight mirror would it be directed to a point with the hole?
Interesting. Could be a cheap way to collect more solar energy to a focal point for high efficiency PV or water heating! Does anyone know the approximate reflectivity efficiency of the mylar? Also, is there a more simple physical system that might be easier than a vacuum to create the concave?
That death ray was fucking scary. You are a genius!
I'm using a pressure sensor and peristaltic pump to maintain constant pressure it is not so complicated and uses very little power. Also I noticed that when the mirrors are air tight the heat from the sun makes the pressure vary and so the focal length also. With this system the focal length always stays the same.
Michel PASTOR is your system pictured on the web??
Not yet. I was planning to make a video about it but never took the time to do it. It is integrated to a custom dual axis solar tracker. The pressure management system in itself is really simple. If the pressure goes above the set pressure plus hysteresis it makes the pump go one way to lower the pressure until it reaches the set pressure. If the pressure goes below the set pressure minus hysteresis it makes the pump go the other way to raise the pressure until it reaches the set pressure. The pump is controlled with a H-bridge. It is too early in the year (winter in the north hemisphere) for me to demonstrate the entire system on video but I could do it in a couple of months.
I wish that could be used for heating during winter. It would be more useful than cooking during summer IMO.
Reminds me of the one James Bond movie where Pierce Bronson as James Bond... A giant solar powered laser in outer space melts the snow and ice ! Bond trying to escape from the instant tidal wave....
have you ever made one 10 feet diameter to see how well it does
Just watch your super moon video, Question: Can the moon power solar panels?
Working on focusing sunlight to excite a laser rod for metal cutting
Brilliant.
How about an aquarium pump repurposed to run backwards or pump backwards teed off to all the mirrors with just one small aquarium pump quiet?
Could you set this up to power a steam engine? Would be very nice to see how close this setup would come compared to an industry standard solar array.
It would require constant supervision. Robotics would greatly aid the supervisor and would be essential for a large engine generator.
I can see this working on a tower with a spyglass that follows the Sun and will funnel the Suns Rays to a centerpoint within the machine; then at the base 360° It will have the ability to direct that energy any which way... A Death Ray. It's either that or a better inexpensive solution will be to have the "Death Ray" fixed on the ground... Then directing that energy to a tower to shot a target from a very high elevation or from the ground to the heavens - as the beam of energy only has to be the size of a sowing needle to take out a fighter jet.
Because I've also seen your Horizontal Death Ray with the plastic liner on top of the 4 pillars made of 2x4's and the water bead right above it... And was shocked when I witnessed the glass bottles melt.
There are ancient inscriptions on temples that describe 4m parabolic mirrors used to melt rock. Apparently two of these mirrors where used at the same time on the same focal point to create a beat frequency of sorts and this would melt the rock so it could be cast like a polymer! Could you try this on some hard granite or something?
it can make glass from sand for sure.
Is the converged light point sized ?
Dan, I love the work you do. With that said have you ever attempted to run NITS calibrated sensors to get a actual power output reading on your projects? Im tired of all the neigh sayers scuttling anything non-standard as infinite energy devices.
they use gold surfaces on lenses to catch the infrared in astronomy and infrared detection devises, this might increase the heat comming from a Parabolic mirror
I wanna see you do clay pottery with this
nice.....
Why couldn't you put spray glue on your backing before you vacuum the mylar and then once it pulls the mylar back you could stick it to the spray glue to hold it in place and in shape forever
Do you have any max temperature data?
How hot can the reflectant energy get?
Good a table with wheels, time to move the death ray to conquer the world
All those watts without solar panels - how do you convert that into usable electricity to power a small house?
I whant answer on that too
Maybe a stirling engine
Steam engines are far more efficient that sterling engines at converting heat into electric power., plus distilled water is a byproduct if you collect condensation in an underground condenser to cool the steam
Get the mirrors big enough -
Buy stirling engine is easiest
steam engine is easiest and cheapest and most efficient.. stroke vs turbine as you scale up
Nonparabolic Flat reflector - shine on solar panel
Optional - distill ethanol from sugar
Why dont you use scrap mirrors, it should be cheap and last forever?
You can glue bunch of little mirrors 20x20cm on small steel plates with holders on them which could be aligned by hand to center focal point and than instantly welded to the steel construction of parabolic mirror.
Frame could consist of 25 mirrors 20x20cm to get 1sqm parabolic reflector.
I will paste here the text I posted on another video about green energy that could use those reflectors with sand as material for heat storage.
Ok I think we could buy old steel tank from truck at scrap yard 3-4000 liter, put it vertically fill it with sand, molten salt or whatever stores huge amount of heat.
We make one window 30x30cm with heat resistant glass, vacuum inside and coated one way heat transfer, similar like vacuum tubes for water heating collector.
Behind its black coated copper that transfers heat received from window to material (maybe molten material would be good to assure good contact with copper ribs).
Now we make alot of mirrors that would be guided with motors to reflect huge amount of heat through that window and heat material up to 400-500*C
We can also put 4 mirrors at window at 30* to collect light that would otherwise not hit the window and size receiving are up to 1m.🔳
We can then extract heat through copper tubing inside tank pushing water or some other fluid through them, even connect steam turbine to produce electricity but am not sure how much of energy can such tank store..
If that kind of tank could store big amounts of heat we could use it for making electricity through steam turbine during summer hot days and use it as battery during winter nights to heat home and make electricity.
Am not sure if about 50sqm of mirrors would be enough to make such amounts of heat during winter but its cheap and very earth pollution saving project.
Thanks for making me think of this idea and please everyone who have some recommendations or ideas to add something..
Hey can you provide link on how u made it?
remember the giant water lens you made?...do you think that mylar could be used similarly creating a mirror instead of a lens?...then all you need is a hoop and a couple of gallons of water...im not sure how short of a focal length can be achieved...it might only work well at about noon...but going large could compensate for being oriented slightly off...imagine cooking above a nice cool water mirror....about 5 or 6 feet across
I also, believe in what you are doing.!! However,
I believe that it's so much Easier to just make the parabolic mirror, keep it's shap" All the time.!! As the channel, ( Night Hawk does ).
It's just so much Easier, & maintenance free,
With a ton of less, trouble 😵💫😵💫😵💫. He ( nighthawk in Light ) also, mentioned you as his inspiration to work with, this " MYLAR "!!!
Theory that csp heliostat arrays like the ivanpah array in California could be used to find super civilizations and Goldilocks planets in space at night by aiming them at stars then cameras on the towers at night. They could also be used to air solar lasers at asteroids to redirect them from the earth.
머리가 예전보다 많이 벗어지셔서 안타깝네요. 세월을 이길 수는 없죠. 동영상 잘 보고 있습니다.
While watching something burning, as a result of the heat, is impressive and dramatic, I would much rather see this put to a practical use. Maybe the heat could be used to generate steam to drive an electric generator or operate similarly to the large commercial systems that use mirrors to beam the sun to the top of a tower?
could suspend a black cannon ball in the middle of a glass water container and set the 3 focal lengths on to it
nice
What are they for?
How are you calculating 3kw?
Why not just bend cardboard in a curve and apply the mylar directly, maybe with spray glue?
Instead of a vacuum pump, have you tried partly filling the evacuated space with water and then letting gravity create the vacuum by pulling the water through a tube to a lower place.
But what are you using this for?
have you tried a steam engine with this to generate electricity?
I have 3 larger steam engines. I need the larger footprint and thermal watts to get the sustained pressure required.
Last time I watched you was like 10 years ago and you still solar burning wood with mirror..LOL.Well, you aged a bit, but still fun to watch.
Aged for sure. When I would upload a video "back then" I would be critical on how I looked on camera. Now, I am like damn, I looked like a young person. Turned 50 years old this year so after going to my 30th class reunion 2 years ago I am holding up to most of my peers. Some I did not even recognize, others looked the same in a weird way (like their parent/s would have looked). Those of us fortunate to make it to the 40th reunion will be interesting. Thank you for watching…….and enjoy our videos.
50 ?! Ohh you look fine then.I didn't know you turned 5th cross already.Yess true, those class reunions.LOL.Damn,time goes fast.Have you thought to get into renewable energy solar business?Might be good in your area Tampa - Orlando .Down here in Naples solar is dead,people don't get it.I do run my solar house and I love it.
Can i have the simulation for this please
For every square meter of sunlight there's a KW of power....but they built a 30 meter reflective fresnel with concentric metal rings that actually puts out 53kw at peak sunlight. A 30 meter circle isnt even 30 square meters...that means lens-style concentration actually puts out 2kw per square meter, especially when the sun is directly overhead because you have gravity on your side, and a higher ambient temp.
I believe this is because you're not fighting gravity, as well as incoming photons, when you use a lens. After studying black holes, we learn that gravity does affect photons, and the space above the mirror is also saturated with photons raining down, giving it less "umph" in any direction other than the source.... so a lens is the most efficient form of concentrating collected photons from the powerhouse of our solar system. Still, having the parabolic mirrors is handy because cooking requires heat on the bottom of the pan. I love this culture I stumbled upon. I kinda want to buy a big ass mirror from his website
Boil the ocean!!! Distill water!
Fukushima working on it
You don't think the plans are already in process??? What about the seawater purification plants in CA..The only reason its not being done on a larger scale is that its not cheap enough on the corporate scale
It's not cost effective.
Dan I'm impressed with your videos and your unwavering passion. Solar thermal (especially concentration) seems to have exponentially more potential than PV.
If willing, I'd like to speak with you and pick through your experience and knowledge to see if a commercially viable heating system can emerge. Do you have a private method of contact? Thanks
Why not spread some glue inside the dish so when you vacuum it.. it glues it in that position.. or I guess the dish is not a good shape..
👍👍👍
solar hot water just heat a small aluminium computer cooling block and used thermo convection to cycle the water
Concave mirrors. CONCAVE MIRRORS! CON-CAAAAAAVE!
you look like the guy from grow your greens
But gets to the point PDQ - instead of rambling while stoned.
If you use gold colored mylar and paint the trailer gold too and give it a fancy name, then humpty trumpty wont mind you testing it out on him as his new hair dryer, because wind based hair/gold electroplated steel wool drying keeps causing insult to injury.
:-)
What's the application for this ?
You could get only 1 Kilowatt electricity at most, or 0.3 Kilowatt averaged to whole day.
You finally put your RUclips money to good use and got a haircut.
I'm strangely relieved.
Me too, at some point you realize hair does not grow evenly like it once did :-)
@@GREENPOWERSCIENCE I'm guessing your wife approves😉.
Sort of, nature/hair loss had more to say about it than either one of us.
@@GREENPOWERSCIENCE LoL. I hear ya. I have a lonely patch of hair in the middle of my forehead.
@@GREENPOWERSCIENCE I know you are the "parabolic guy" but is reflective mylar or aluminum foil better for the inside of a solar cooker box type? Not just for reflectivity but mainly to keep the heat in (regardless of insulation) ?
The sun gives out 625 watts per sq meter, those three pads of 1m2 are less than three full kilowatts per hour duration.
It would be kilowatts regardless of duration since kilowatts is just power or energy per unit of time.
@@iloveamerica1966
That is really not how solar math works; a system is energy per hour and a house needs 3kw per hour so 24 sq meters of 20% efficency panels or 12 panels of 2×1 meters, to get a full fucking 30kws per 10 sunlight hour period.
@@robinhyperlord9053 What are you powering with 72Kwh / day? My house with water pump and pool only uses 30Kwh.
Arquimides en ciracusa quemando las naves de marcelo.
I'm practicing gem faceting. Melt some different minerals into a cool concoction so I can practice cutting. Corundum. Melt some corundum. You know, the stuff sapphires and rubies are made of. Al2O3 I believe. Aluminum oxide or alumina.
We know how this works, can't we make something practical that can be used for energy production? Let's build this in a safe insulated housing with a boiler and a "Green Steem" engine and produce hot water, distilled water and electricity.
Jack the only thing I can see is heating a water tank and use steam energy to run a generator but then I'm not as up on these things as Dan is. I once asked Dan about a no electricity way to generate ice or colder temps than a zeer pot could (50 degrees F) and he said he found a way but would not tell me what that way was which I found really suspect. . Perhaps he could use a giant Peltier device with that amount of heat to do it.
HipHopKiller94 And yet you are still tuning in...
You could probably do _something_ with it in that capacity: 3,000 watt-hours is just over 10,000 BTUs per hour, if you could manage a 100% efficient conversion to thermal energy. Even assuming a 50% loss, that's still enough energy to raise the temperature of about 2 gallons of water to more than 300 degrees Fahrenheit over that hour.
Could you do something _practical_ with it? That's another question altogether.
PhycoKrusk - well people already do something practical with way less than that say 150 F. using passive solar heating systems. They can heat entire houses with them and use them to provide hot water with showers.. and a ram pump circulation system that carries the water up hill - no electricity needed at all. There's tons of ways to do Everything low tech but sometimes we need some electricity for low wattage low voltage electronics. If we could at least charge battery banks with such devices that would help out a lot. Solar is expensive.
??? I mentioned an RV fridge = absorption refrigeration, other than a cold front, there really is no other options because the cooling process is always a heat pump. The best method is a solar panel to a small electric ice chest. I do not recall any secret cooling devices up my sleeve. If I had it, I would have used it last summer.
I was working on the RV fridge _ concentrated sunlight but realized it was not a safe project to make a video on as there was a large risk for the water separator to violently rupture.
It's to bad you couldn't fill the mirrors with spray foam to keep it in that shape permanently
woa.... i'd never thought of that.
Wrong. Heat and cold will change its dimensions, even with the foam
+smasimulationshop Pretty negligibly tho i'd expect, i wouldn't expect it to change the focus. The curve will be pretty well "locked in" as the foam sets.
Does not work.
Foam does not hold its shape against weak objects, it bulges and expands to however it feels like. Place foam spray in a beer bottle uncapped or it will explode when you break the glass, once solid, break the glass, the final result is something that sort of looks like a bottle with lumps all over it.
Look on 1:16
Have you noticed the hexagon sun lately?
The mirror caused the reflection to look that way on the video.
Instead of burning stuff y not try to run a steam engine off the heat generated
Video is missing the bikini wifey
Enjoyed it last time, looking forward to enjoying her the next time
I would love to make you an intro for your channel if your interested hit me up
Will Mylar reflect 99% of UV, Visible light and Infrared rays falling on it? Is it possible to make the focused light from one concave mirror go into a cubical box via a small hole? Could you please make a video on it. Thanks
