  • Usando cobre en lugar de acero inoxidable obtenemos mayor rendimiento

  • try mixing in a bunch of charcoal with the steel wool

  • Fried your camera at 3:50 huh?

  • 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?

  • That's the ticket to instant boiling...steel wool. Good move. Long time watcher, first comment...keep at it!

  • Imagine how much more efficient this would be if it was on a raised platform, and therefore closer to the sun. !!!

  • Great vids.

    Rojas, thinking about ordering one of your mirrors. I priced plexiglas and it is on the capitalist out the roof $ list. No, DIY for me on this one. Tango Yankee

    

  • Capitalism is where money makes more money. (Remember the young American Revoultionary Thomas Jefferson warning

    "If private banks are ever allowed to subvert the Constitution of the USA by setting the value and coinage of money the corporations

    (now called Big Immortal Persons) that spring up around them will

    Socialism for the Bankster Monopolistic Capitalists

  • que aburrido eres...

    

  • This video turned a little squirrelly at the end :),Tks for all your great video posts.

  • 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.

  • Dan, I have a question. When you magnify the suns rays are they harmful to your eyes?

  • 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.

  • why not just hang some b lack  pe film in there.

  • If you built a steam engine using this method, how much energy could you collect from this compared to solar cells using equivalent sunlight?

  • Need to marry you **busizz4me.info**

  • so you could put 3 0r 4 tubes of 1" dia. running thru that focus and you have an on demand hot water heater or steam generator depending on your rate of flow......... Interesting possibilities from a 2 sq meter? lens.........

  • 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!

  • awsome she'll never know lol

  • Will the glass hold high pressure steam if used as a boiler ?

  • Is it just me or does the glass get brighter and glow? It looks like a chubby light saber one of the fat characters would use :X lol

  • That looked really cool before you adjusted the camera at 2:50.

    Very interesting video.

  • this is the best way ive seen.

  • should paint the steel in black, use high temperature paint (like the one used in car engines). you are loosing a lot of the energy with the steel reflecting sun light ;)

  • 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?

  • @bshupejr

    Late reaction, but in your case I would go for a batch heater in an isolated box painted black from the inside, and adding some mirrors at the outside for more sunlight exposure to the tank.

    The tempered glass on top retains the heat during the sunny and less sunny parts of the day.

    Fresnell lenses are good for direct and powerful heating with full sun; see their video about solar cooking, Denise bakes an ommelette there and has some problems with clouds.

    Regards from Mexico

  • @321ozzy

    (2) The reason for painting the box black from the inside is that black also has a radiation effect which heats up the tank in the box, on the contrary if you add mirrors on the inside, pretty much light will be reflected out.

    Regards

  • 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!

  • You try to make a barbecue with this? It will be a good experience video....

  • Pity you didn't catch the squirrel on your high speed camera...

  • Your wife's gonna kick yer ass for using her fancy chinese tea maker for your backyard experiments!

    I heard you say, "...she'll never know what happened" HAHAHAHA

    $10 say you drop it and break it !! HAHAHHA

  • :-) Bought my own for next video.

  • @GREENPOWERSCIENCE

    "I'm going to pretend that I bought my own for the next video" -Fixed

  • @STARFIRESOLAR ... my name is kenneth van horn and you should use the solar dishes to send light through mirrored piping then piping is sent into a mirrored box and inside the box will be several solar panels that spin or use a cooling system.exhaust from this box will be used to help something else to save lives.

  • outstanding!!!!  Now what do you plan to do with it?

  • 6:50 "i really don't think they know what they are doing" .... :) made me chuckle

  • Your videos are fantastic! I've learned so much. Would you tell us the type of camera and software you use for uploads?

  • Dan is the Man! Just a suggestion though, to make your project more efficient, go with flat black! I don't know how many times I've said that lol... You should have flat black metal in their.

  • Also, I am debating whether simply a flat black piece of metal will work better in the container.

  • Mirror the inside of half the inner tube and blacken the same halfs back while placing it into a mirror trough.

  • do you know exactly what temperature this is? Seriously, the bigger lens the better? You could possible smelt metal or do blacksmithing with just sunlight HA! No smoke and no wood to burn (but can only be done with good sun) Hey, it would save money on buying logs or gas :D

  • The last guy who used my Teavana Tea Rhapsody Glass Tea Tumbler to zap with a Fresnel lens after filling with steel wool:-) LOL Hey, question, does all double glass have a vacuum. I am guessing it to be yes as the heat process of making would have to? Or not, you should buy your own and break it to see if it makes the woshing sound. I think the answer is yes, any thoughts. How do you get your videos to be so damn pretty looking? Better than SD TV.

  • They are filmed in HD, usually with an HD camcorder.

  • It's amazing how easily you can boil water with the sun!

  • seriously man these experiments are so cool !

  • 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.

  • 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

  • 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!

  • Are you talking in Fahrenheit or Celsius? When I heard you say that the steel wool would make it hotter, I thought, "what the fuck, he grabbed it with his bare hands?". A real scientist uses Celsius.

  • or Kelvins

  • If it was 70 kelvin, his hands would be frozen solid after touching that steel wool. Oh and the water itself would have already been frozen.

  • my comment was in regard to what a real scientist uses.

  • Oh yeah, but that's not entirely true. A lot of chemists and physicists use Celsius, at least part of the time. No one uses Fahrenheit, its points of reference are almost completely arbitrary and its increments are stupidly small.

  • Why so much steel wool?

    Wouldn't you just need enough intercept the light?

  • Fantastic!!!!

  • Actually, a candle would work to heat the contents. Candles are hugely radiant in the infrared spectrum, and infrared travels through a vacuum just as well as the rest of the electromagnetic spectrum. Otherwise, someone just wasted a ton of money on the Spitzer telescope.

  • I would have been more impressed had the tubes been made in the USA. Sick of seeing made in China, a communist country. We need our industry back in the USA. Other than that, good demonstration.

  • lol n00b

  • Really thrundar - you would have been more impressed? Why, I wonder. Is the physics of heat and boiling different in Chinese glassware? I'm pretty sure it would be no more or less an impressive demonstration whether the tubing was manufactured in China or Chicago.

    But hey, way to wedge your simplistic economic views in. A clue for you - communism isn't eradicated by refusing to trade - witness N. Korea and Cuba - it's eradicated by extensive trade with capitalist countries.

  • Tell that to all the unemployed Americans thanks to NAFTA and such programs that are destroying the US economy. Those Chinese workers are better off how? Only their masters profit I believe.

    Yes, "simplistic" is a compliment. Ever hear of K.I.S.S.? Keep it simple stupid. Thanks though for keeping it clean. It shows just a touch of maturity.

  • Your problem, in addition to reading comprehension (where did I endorse the NAFTA disaster?) is your lack of faith in capitalism. We didn't win in Vietnam with bullets or bombs - but we're slowly winning it today, one McDonalds franchise at a time. The communist ideal in China is being turned on it's head by capitalist trade, and there's no going back. Simply branding a nation as "communist" and exiling them financially just doesn't work, and it is simplistic in the extreme to believe otherwise.

  • @47f0 Totailitarian Monopolistic Capitalistic is Entropic not sustainably syntropic and you have taken the short term view and are in awe of a cancerous economic model .

  • @rwsandham - sorry, but capitalism works. It works because we are greedy little monkeys who want one more banana than our neighbors have. HOWEVER, unregulated capitalism is absolutely malignant. Like fire, it must be controlled, so it cooks our steaks on the grill without burning the house down. I am an unabashed capitalist socialist - nature suggests that forces should counterbalance each other, and pure socialists are just as deluded as pure capitalists.

  • I wonder how much more efficient copper wool would work?

  • Interesting. Will be more interesting how you you about constructing glass vacuum tubes . Do you expect the tubes to withstand the pressure that may be needed to do any real work with the steam engines?

  • 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.

  • Your awesome!

    I think this is the science ideas of future energy.

    This is the inventiveness we need to move forward.

  • thats pretty neat....

  • ROFL! @ "she'll never know what happened" You get in trouble a lot don't you? lol

  • I think it is part of life:-)

  • Make a solar still, Dan!

  • Is the insulation of the double glass container good enough to boil water with no lens?

  • Not user if this one is, the borosilicate tube will. I need to test the tea thing today.

  • This video was filmed at 11:58. I know because i was hiding behind the foam crocodile on top of your purple ford mustang convertible.

  • awesomeness!!

  • Comment removed

  • Your so lucky to live in a place where you actually get to SEE the sun.

  • 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.

  • Dan rule number one in any marrage never touch the misses stuff, ever! But good deal you got away with murder this time I just hope she don't find out but good experiement!

  • LOL that's the first thing that came to my mind too. Borrowing her stuff and hitting it with high intensity heat didn't sound like a good idea. :-)

  • lol, if she watched his videos she'd know!

  • :-)

  • 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)

  • Teavana is not a mad scientist like you Dan. How long did you have to play with Denise's stuff before she came home?

  • keep at it dan! we need ya!

  • Where can I get one of those wood things?

  • LOL...'wooden thing'

  • instance skin cancer

  • instant noodles

  • What works good is a green beer bottle. I've seen that work in 30 seconds

  • where can i find a fresnel lens at

  • @hillbilly766

    order one from Dan

    I got two from him at a great deal

  • Where can I buy a jar like that ?

  • nice, thx a lot mr Dan.

  • 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...

  • Epic squirrel music xD

  • she will never know... untell she watches this :p

  • lol 3:17 wow uh er pretty instant if ur wife asked why her tea taste funny just say u cleaned it with steel wool :x

    lol the squarel at the end*looks back* uh oh i ruined his vid scampers off and hides 5*

  • great videos.

    but please edit a bit more in scientific manner.

    but i'm wondering: aren't there any metallic residues (even microscopic) that stays in the water? like BBP with plastic bottles ?

  • 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.

  • great video as always...loved the random squirrel!!

  • Hi Dan,

    I combined a 3' by 4' mirror with my small sallite dish, it cracked the glass! Learning not to have such a small focal length with that much solar energy. One concern I have with your setup is that you may be getting impurites in the water when you heat up the steel wool in that way. Might not be safe drinking water.. Great ideas, and don't get Denise mad at you, we hope to see you back he he he .

  • Can you cook some chicken in those beekers?.... I think perhaps you have the makings of a great bbq and smoker oven broiler there. Theres an idea for ya big guy.

    Love the lab work man keep up the great work.

  • is this a viable way to run a small model steam engine for display purposes?

  • I love your experiments! Always making great progress.

  • nice
