- Solar Fresnel Lens and a Tevana Tea vacuum container + steel wool nanoparticles. Superheated www.greenpowers... steel wool creates nanoparticle surface structure.
The steel wool has a vast surface area, when superheated dry, the smooth shiny surface structure opens up creating structural crevices less than 100 nanometers that act as nanoparticles. Any previously mirrored metallic object that is dulled with heat alone has this micro structure. This is different than sanding. The direct contact with the aqueous solution allows for optimal heat transfer from the heated metal surface to the water. Steel wool is a good choice over mud bath nanoparticle suspensions as the skeletal structure allows for enhanced area coverage in 3 dimension vs that of a 2 dimensional mud bath.
Green Job Career Training. BOILING WATER. I am working in a very efficient boiler that can retain more heat. The concept can also be used in the large Stirling Engine. If very little heat escapes from the boiler or displace side of a Stirling Engine, the efficiency and power will go way up.
You might consider using something under the container to slide it in and out of the sunlight. That would help to keep your hands out of the sunlight and also avoid shocking the glass with a sudden cooler temperature.
Also, love the ominous music at the end when the squirrel appears.
There's not much you could put under there that wouldn't melt.
This would be a good idea for getting distilled water! Using the cling wrap/littler marble method you can condensate the water using the cooler ambiente air into another container. A taller, trasparent wide glass/plexiglass tube can hold the boiler inside and at the same time keep the steam from escaping while letting the sunlight in. Good for having usable water during emergencies!
The steel wool is heated without water present, this turns it a matte blackish blue color.
I agree, shiny metal is not good for solar collection heat exchanging. The advantage is steel wool has a tremendous surface area directly contacting the water.
It sure seems like large scale water heating for something like steam power generation or heating a dwelling would be extreemly difficult to accomplish this way given the localization of the hear source and needing to reposition with sun movement. However, using this as a method to heat a surface for cooking seems like it would be a slam dunk. BBQ (as previously mentioned) or even a large griddle surface etc. Thanks for the video!
Oh I love these glass jar experiments.
.
Impressive, cant wait to see steam boiler built
I actually do... enjoy your videos dan.. you are passionate about what you do and for the right reasons and doing the business model you have in the right way... through kinda open source/freemium type model... which is the way business is moving.. give the idea away for free anyone can make it themselves.. but you do offer finished units and kits etc at a reasonable price.. and bing... you are chocolate chunk ice cream and not prune ice cream... difference of night and day folks.... you CAN make money by paying it forward by giving the idea or design away freely and then just charging for what you BUILD and sell to people who maybe want to have such who cant for whatever reason.. oh btw.. the dog is a very nice addition to the video channel and like I have a cat who helps me develop as well.. his name is Mr. Bill Clinton (Yes that is his registered name when I adopted him)
Try some carbon fiber roving. It's carbon, which is non-toxic (may have sizing/die lubricant agents that you'll want to wash off) and it's naturally black. Roving is essentially what fabric is woven from, and it poofs up really nice. I've used it several times to make electrodes for carbon-zinc batteries that had to be really small and flexible, and it's electrochemically stable over very long periods in ridiculously caustic conditions. Love the vids, keep up the good work!
I Suggest you make a pair of Variable cross polarized sunglasses.Before you damage your retinas if you haven't already
lol that squirrel. :D
Now convert a delorian to run on a stirling type engine using fresnel lens on panels around the vehicle, which channel the light to a central structured chamber. Still be a piston car
Dan, you really need to follow this steam through to the end and make a working steam engine that produces a goodly amount of electricity, enough to run several appliances or an A/C unit. Something worth building to help in living "Off Grid."
It's amazing how easily you can boil water with the sun!
That bottle was luminous!
try dark material like carbon powder
I am looking for about 50 PSI with a larger volume. Also if higher pressure is needed, a steel pipe inside of a glass vacuum could be the answer. If large enough glass is available, then glass-vacuum,inner glass, oil/element/steel or copper. The oil would transfer a lot of the heat to the encased water tube/boiler.
This video turned a little squirrelly at the end :),Tks for all your great video posts.
Your awesome!
I think this is the science ideas of future energy.
This is the inventiveness we need to move forward.
Only wish I could have seen this when it was first posted.Great video!! Does this remind anyone of steam powered power plants? Knowing little about the fuschl lens workings just with what little knowledge I have of this can definitely see a power plant that could operate solely by the use of these lenses.Most the steam powered plants sit abandoned for different reasons I'm sure.But one shot in the dark is they don't cater to big fossil fuel oil companies or coal companies.The use of these lenses is definitely a renewable energy source.Can't see many side effects to the environment either.The sun drives everything else so why not power generation.Hopefuly you've kept at this and discovered even more about it..Seen one video where a guy was trying to generate power from steam but was using it's pressure to drive small generators he had demised from small two-cycle engine's.He simply took out the spark plug and ran the engine backwards by the steam power. As a result turning the flywheel where he had the generators. The problem he was facing was a material that could take all the heat generated by the lenses. He could not control the amount of heat he was melting steel, copper, glass any type of pipe he tried.. Assuming these pressure systems are in need of very high pressure more so then what would be generated from boiling water alone like that of a water heater or a pan of boiling water for tha matter.. The last I heard he had some success with a titanium pipe to resisting the heat energy created by the lenses. Ironically this video came up after I had viewed an abandoned steam powered power plant. I'm the outside the box type thinker and two and two makes four every time.Can just see this as a reality in the future. One has to agree that water as well as the sun are the two most nurturing substances in the known Galaxy no life can exist without these two factors in play.. There's energy in equation one just has to figure out how to harness it. And to what angle to come at it from. Like I said hopefully you are still hammering out this I'm going to say technology. Like the great tempest of the pass keep hammering...👍✌️
Just superheat it in concentrated sunlight or with a torch. It turns a nice deep blued, the same color as the surface collectors of evacuated tubes.
been thinking about using this as a replacement for nuclear power since like 2001, nice to see a proof of concept, never thought of steel wool! I strongly encourage anybody with the wherewithall to find a turbine and an alternator ;)
Do you have a suggestion for what kind of turbine and alternator? Please. You know how important it is.
Not sure, this is for steam engines vs drinking. If you are making tea or coffee, the dark leaves or beans replaces the steel wool.
have you considered using two bottles, linked together with a hose? one bottle would be for heating using the Fresnel lens, and would have a hose going into a hot water tank, and the cold water would be fed from the bottom of the hot water tank and be linked by a hose to the bottle being heated. as the water heats, it will rise up in the hose to the top of the hot water tank, causing a siphoning from the cold water bottle which would resupply the hot water bottle - a closed loop if you will.
oh, i think i found it.Hi dan.i'm going back to the trough mirror video to ask some questions on parabolas and heat collection. i love your work.
Hi Daniel. Like your work much, but would love to see a solar powered steam engine. Definetly can imagine it with the vacuum flask you did your experiment above. You can even use a number of those simultaneously, possibly with additional lens for each other flask, and connect them to single preasure chamber (and possibly extra watter reservoir) by some valved tubing. Would that design have some point in it, or would it be much easier to simply slap there a solar panel instead?
That looked really cool before you adjusted the camera at 2:50.
Very interesting video.
Not user if this one is, the borosilicate tube will. I need to test the tea thing today.
Thanks Dan. I was using a regular camping kettle with a satellite dish parabola (burns wood real fast!) and wondering why it would only sizzle and not get a nice boil on...
obviously losing too much heat from the crappy spout, its not insulated, and of course its chromed so its reflecting energy back also!
How could you set that up to say.... heat a swimming pool. Will the focal point heat water directly or would you have to have a transfer medium?
Do you wonder how much heat the shiny steel wool is reflecting away?
i wonder if there's some kindof black stainless-steel-wool-like material.
i guess you could spray/dip black paint onto it, but i'd expect the heat (and the flex of the steel-wool) to deteriorate the paint, it may chip-off into the water. Perhaps special heat paint (exhaust paint)
Yes, but they stress easier with heat changes.
Thank you for the great comments:-)
Hey Dan, How about using a mirror to get a horizontal beam of focussed light? And then behind the object you make a white screen (Or another mirror for double focus) so the beam won't burn something when you remove the object.
My favorite coffee is made from boiling water and steel wool
Hi Dan. So far I love all your videos. There's always some good info in them.
You mentioned the stores putting candles under the tea maker. I think that, if nothing else, they're getting people to buy the candles which pumps up their sales volume.
Keep it up. I love this stuff. I wish I had your resources.
keep at it dan! we need ya!
Can this technique be used with a closed loop black pipe system for generating steam and power a steam turbine?
Could you attach that to a pressurised system leading to a Tesla turbine to generate power? Just recently watched integza’s video on Tesla turbines and it seems like this combination could genuinely be a game changer if scaled up to a big enough scale
Can a Fresnel lens be used to generate enough steam to run a generator and generate a useful amount of electricity?
yes
Zach how?
You use the Fresnel lens to generate enough steam to run a generator that generates useful amounts of electricity.
Hey great video !
Which material could i use if the fresenel lens temperature goes upto 800 degrees C. ?
most worthy mate , big thank-you for sharing
I've thought about using Fresnel lenses to supercharge a solar heat system because I live in a cold climate, but the cost of any lenses is prohibitive. I don't know all the measurements, but I've wondered how much energy could be harvested combining a Fresnel with a sun-tracking system to direct the light at a target. Probably not enough to be worthwhile where it is overcast or has a lot of snow when it's cold.
How about using a linear fresnal lens? They don't cost as much as you may think! You have some very good ideas!
lol, I like the plot twist at the end
I wonder if this could be used to heat homes in the winter ? Like a series of sealed drums full of water or oil, and heat it with the Fresnel lens, then the heat will radiate throughout the day ?
I wonder if the reflective natural of the steel wool is shoving off the light. I suspect so. I'd imagine if you could overcome this it'd be even more efficient.
Mirror the inside of half the inner tube and blacken the same halfs back while placing it into a mirror trough.
I dont understand why does the metal help the water to heat up?Would it work better if some kind of a black object was used in the water?
Kingspan Thermomax solar themal evacuated tube heaters would be ideal, The fresnel lens system could be used to supercharge the system.
You should probably invest in some laser glasses
I wonder if using a fused quartz crucible would hold up to greater heat and internal pressures.
Why on earth did you not show what you are using to heat the water?
great idea .. glass can't stand pressure ... application may come later ..
would you show videos of making thermal acoustic engine?
Will the steel wool make a good conductor of heat, cos Iam thinking of getting the heat from upstairs down to kitchen through thick copper tubes insulated with ceramic for cooking purpose
try copper tubes with copper cable chunk in it, then smear the tube with thin carbon powder. hmm i miss it so much, make some small version of them to move 3 dc volt dynamo every day, then collect them on some board, then make paralel electric circuit of them.
I wanted to see what was focussing the sun's rays!
What about copper wool? or aluminum but not sure if it exists.
Is this water safe to drink or to cook with?
yout should try boiling water in a plastic bottle i know you can do it over a fire the bottle just cant have air or somthing like that
What kind of eye protection do you use...will a welding helmet with a number 10 lens be ok???
NO GOD BUT GOD ....What Is Islam?
Islam is not just another religion.
It is the same message preached by Moses, Jesus and Abraham.
Islam literally means ‘submission to God’ and it teaches us to have a direct relationship with God.
It reminds us that since God created us, no one should be worshipped except God alone.
It also teaches that God is nothing like a human being or like anything that we can imagine.
The concept of God is summarized in the Quran as:
{ “Say, He is God, the One. God, the Absolute. He does not give birth, nor was He born, and there is nothing like Him.”} (Quran 112:1-4)
Becoming a Muslim is not turning your back to Jesus.
Rather it’s going back to the original teachings of Jesus and obeying him

great video as always...loved the random squirrel!!
Hey Dan, loved the vid, I like seeing someone that is into this out of the box stuff too. Lot's of people I talk about this stuff too either go, "Huh? What? Whatever" or they pull that SpongeBob line "Good luck with that" . I can't stand being around people that don't understand how much better things could be, and their failure to understand keeps things that way. I've always been into stuff like this from way back, Ed from Coral Castle, Tesla, etc. The government is hiding the truth.
Is the insulation of the double glass container good enough to boil water with no lens?
Maybe you could set this experiment up again on a cloudy or partly cloudy day to show the power loss? I live in the NW so I dont have the sun you do but on a nice day I could see putting this to good use. Also, what does a lens like that cost?
Find them inside old projection TV's
Maybe this has been asked and answered but I've been theorizing about this. Can you use this boiling method with sea water in a type of desalinization set up. What I've been wondering about is using the steam created to power a generator which would be used to power a tracking/positioner for the lens. Then once the steam condenses you would have filterable water to drink.
Why do you use the insulating vacuum glass container? Will it have the same effect when using normal (single layer) glass container? Thanks
Cuts losses from the hot water
Can galvanized pipe be used to distill water or will the fresnel lens break down the coating and taint the water.
What about using black gas piping¿
I wonder how much more efficient copper wool would work?
I like your solar Sterling engines better. Steam boilers are very dangerous. Even something that small is. In fact that is why Robert Sterling came up with his concept. To save lives.
what if you used anodized steel wool the black should adsorb even more
I don't think you can anodize steel only aluminium... maybe black oxide (if that works!)... good idea to make it black though.
you can but it erodes in the process. Maybe shift to Titanium, which can be... enjoy that $ bill.
Will the glass hold high pressure steam if used as a boiler ?
You have boiled water using stainless steel wool in Tevana tumbler. If someone boils water like this and gets / traps its steam as distilled water if this water will be healthy / drinkable in the long run....! Any advice.
I would use a river rocks that are naturally back in color, inert.
hi dan, I'm interested in making solar cells enough to run my window air conditioner. It cost me double to use it. i've seen your videos but still not clear on connecting the ends on a row of cells,and the backing, " what is it made of" how to seal the entire cell. I have dyslexia and it's a mess. THANK YOU!
Thank you for sharing your knowledge. can one leave the lens at a set angle or must one follow the sun meticulously? any further developments are eagerly awaited. Martin Brandt
Y q tipo de materiales puedo utilisar
so using this you could keep a small pond from freezing?
eah
Maybe fill the tank with an oil and the steel wool. Then put a metal pipe with water in the middle so you can build pressure.
How could you use this to purify drinking water?
put a lid on the top which runs out in a tube to a coil in the air away from the heat source - it will condense and then drip into a catchment vessel. You'd also have to have a feeder line for cold water into the bottle to keep it filled unless you wanted to do just one container full...
DID ANYONE NOTICE THE SASQUATCH BEHIND THE BUSHES???? AMAZING !!
Parfait comme chauffe eau solaire
Why not use aluminum wool since it has a better heat conductivity.
If you built a steam engine using this method, how much energy could you collect from this compared to solar cells using equivalent sunlight?
Hey Dan, thank for sharing your work. is that water drinkable after boiling with steal wool or do you think it had metal fragments left in it? Maybe a quick sterilizing process perhaps?
+n sling
You don't think being superheated already would be "sterilising" enough? I think any nanoparticles of stainless steel would eb inert and therefore harmless. Preumably they would sink anyway, so drinkable water could be decanted from off the top.
just put water in a pan with a lid on it and heat it up no need to add steel.
The lens size is kind of impractical in a rl situation. What if you had a bed of smaller lenses like on a solar panel with the water piping in one end and out the other like a reverse radiator effect? the distance to the water would be much shorter too wouldn't it? Still as much heat per cell but a lot more cells and replaceable. Same with the Parabolic mirror, a lot of smaller dishes under a ceramic hob or hot plate and when you want less heat turn more dishes away from the light source.
Works with fresnel as light goes through it. Though with the parabolic, the dish must be >>> size than what's being heated as the light must get around the object to be heated.
I'm sorry if this is not the right way to do this. I am completely new to computers and stuff. I was hoping to ask Dan some questions, if that is possible. Can someone tell me how?
Make a solar still, Dan!
How is it under a radioactive geiger counter
What else can be used instead of Stainless steel wool....? Say stainless steel mini orbs or nuts bolts or copper chunks or what....?
Anything dark, for potable water needs use black river rock
its possible to heat up sand and from the heat of the sand boil water and use it to generate electricity ?
why heat sand to convert ?. just a wasted step!
CUBETechie sand turns into glass when hot enough? ;) use a metal pot and a locking lid with a steam vent.
Dan Hart i hear that is a method to storage the heat for the Night to use this heat to boil water and generate electricity
try silver plated steel ball, or chunk of copper wire
where can i find a fresnel lens at
Suppose that one was able to use the already commercial evacuated SHW tubes as the basic structure, would filling the tubes with copper wool (already with say AMCRO selective surface) i) would the 'wool' prevent thermosyphon from happening and ii) would having the wool inside the evac tubes be enough to create steam instead of hot water??
Clency
Shouldn't prevent thermosyphon. Steam will be created, though it should not displace all or too much of the water
Thats pretty darned cool! Did you come up with the idea of using the stainless stell wool? That's ingenious! I lauged when you said Denise wouldnt get mad cause she'd never know..haha..doesn't she watch your vidieos? Your so busted! lol...
whats the purpose of steel wool in this project?
Danilo Majhenic Without the steel wool, the sunlight would go through the clear water without being absorbed. The steel wool is dark, absorbs the heat, and heats the water.
This gives you an idea of how much energy potential the Sun has
I have 6 lens's have you found any more use for them that I might try at home or maybe camping ?? I am giving one to my great niece to use for school and projects, I would like to give her some ideas what to do with it besides just burn things..
well for starters burn things? or heat things up? what can you make with heat?
you tell us? ........ waiting......................... ok here are a few things we can use heat for.......free solar heat... = SOLAR ENERGY .. cooking,..house,truck camper or tent warming,water purification,and to heat plastic to use to recycle plastic! .... WAKE UP !!! AMERICA!!!!
If you are indoors you can stand by a wall or other blank surface opposite a window while placing a lens at focal length from the surface and you will see an image of whatever is outside that window. it works great when the sun is behind the clouds but lighting them up so you will see a bright crisp image of them. This could be good for young people to understand about optics. I'm assuming you are talking about a lens that's about the size of a page, these can also be used to magnify the text on a page
how big is the fresnell lise ?
Imagine how much more efficient this would be if it was on a raised platform, and therefore closer to the sun. !!!
Dan, really like your videos..I would like to ask you a question....do you use a video convertor, compressor. Thanks Rick
Mp4 from quicktime Thank you for enjoying our work.
Hi Dan,
How would a recycled flourescent tube light work as a vaccum tube ?
Too flimsy
Do you have a death wish,??
how big of a lens would i need to heat my 28000 gallon pool??
That doesn't work unless you run pipes through your pool to distribute the heat. I already saw a video about that. God bless.
As aluminium conducts heat a thousand times faster than steel, would an aluminium element work better? It also wouldn't rust.
It would melt though.
i was wondering about this very idea. have you come up with any thing. i have some ideas but am still collecting materials. i am thinking of 5 55 gallon drums linked and filled with water. have a metal boiler set up with water circulating between the storage and boiler. just in the brain storming stage. if you would like to exchange ideas it would be appreciated.
Great videos! Tks I got new ideas now. ;-)
