  • FIRE pooooower !

    

  • This is truly amazing. I would have never believed this possible.

  • This is very practical if your on survival situation and you have the plastic. Collect the water, dry your tinder, start the fire, than drink the water.

  • Very nice, another great idea. I took your idea and used on small scale, have a look at this video and let me know what ya think. Fire from Fresnel Lens

  • Scientifically interesting, but impractical.

  • Wow, that was awesome Dan, thanks!

  • HEY DAN, GLAD TO SEE THIS ONE. I HAVE SOME OF THE THICK CRATE WRAP. WHAT A WAY TO MAKE COFFEE.

    MUDDy

  • nice!!

  • dear dan what you discovered is actually written and discussed in the sacred jewish talmud reffering to the lighting of fire on a holy day. the scholars talk about ways of lighting fire. one by rubbing stones one by sticks one by mixing certain kinds of earth and one by water.. the way to light fire by water is exactly the way you showed only they used glass instead of plastic (i just learned it this saturday and i got your video in my email right after.. are you a prophet or what !?)

  • Cool deal 

  • I can see birds taking a bath in you solar cooker lens.

  • Dan, is there any practical application for this? Can a lens like that be used for PV? or any other renewable energy?

  • Try craft resin instead of water you may need to to thicker plastic for it will get hot as it hardens and let me know how it works.

  • Try craft resin and let me know how it works.

  • thin lexan tank filled with water might work toO..

  • very nice and smart idea

  • what about a 5 or 10 gallon aquarium?? think that would work??

  • wow nice one but your water is not clear enough :That would be more effective

  • You two should be on the Discovery Channel, I hope the people running it are thinking about making an offer soon!

  • Its to expensive :/

  • awesome!

  • Welcome back... Where you been the last few weeks? I've been bored silly with no new GreenPowerScience videos to watch!

  • @stopcraponutube :-) Thank you.

    Working and working on new stuff. I have some PV videos on the way and 2 other cheap collector ideas.

  • How do you invent such things?

  • @onmyown12 He didn't. As early as 700 BC, the Assyrians used polished crystal to magnify objects. Ancient Egypt and Babylon used similar objects and the ancient Romans and Greeks filled glass spheres with water for the same purpose. Seneca, the Roman philosopher, wrote about filling transparent vessels with water in order to magnify objects seen through them.

  • Wait but if it rained wouldnt everything be wet and keep anything from catching fire.

  • @HackSilent - Not directly under the plastic on the ground where the sun would be concentrated, at least probably not. Not unless the rain was coming down at a 45 degree angle.

  • @HackSilent It wouldn't be wet underneath the table, because all of the rain would have been caught on the plastic... nes pas?

  • I Like that a lot!

  • That's awesome!

  • Your always thinking aren't you! Love the simplicity!

  • Very clever.

  • Cool!

    

  • Pretty nifty, dude. I'll remember this tip, thanx

  • Creating fire with water?

    -GENIUS! 

  • the best idear are always the simple one's well done

  • Haha you are a genius! That looks almost like a marketable product. If you make a bag out of it with bungy strap holes on the corners. O jeez forget it! Who wants lawyers anyways? I guess it's dangerous enough just giving people the idea!

  • Excellent, very educational video Dan! I knew water could be used as a lens, such as in simple microscopes, but never thought of it as a solar concentrator. Did you come up with this on your own? If so, congrats on your ingenuity.

  • @mrbr549 :-) I had the idea about 2 years ago. This tarp was milky greenhouse wrap so it was not as effective.

    watch?v=SNVIAvdt-xM

  • can i get a payment plan ?

  • Simple experiment involved with complex principles

  • Simple thing involved with complex principle

  • Hmmm 10c is a little expensive. Do you have some sort of payment plan?

  • that was genius!

  • Great job Dan it's been a while.

  • It could also smother a small child if they play with it , it only taks a second to put it in the trash, safety first.

    Great Idea, I'm going to try this. Thanks for all the good tips.

  • Awesome!!!! Dan...

  • Can you do this with a glass bowl instead of the wrap?

  • @marylou178 The bowl would need to be literally round inside and on the bottom. If not the flat bottom would not let the glass function as a focusing lens.

  • @GREENPOWERSCIENCE Very good camera, what is it ?

  • Pretty cool man!

  • Brilliant!

  • The theory I've heard is that liquid left in bottles thrown to the side of the road is one cause of grass fires. I don't know if it's true or not.

  • Anthony Hopkins said you can get fire from ice by melting the ice into a convex shape with your hand and using it like a magnifying glass. That was from that movie The Edge.

  • are you a wizard?

  • genius lol

  • GOD you guys should make more videos, there so good and informative. Love it when they appear in my subscriptions

  • What an awesome, simple idea!

  • Great. The only problem is that it need to be flat you is not possible to rotate the lens.

  • Very well done Dan !

    Now you know how to start a fire in the desert or forrest, when you have no matches

    but only plastic foil and some water...

    Great video.

    Regards, Stefan.

  • thats pretty cool

  • Super idea Dan! Awesome, thanks.

  • Put several in a series over a water pipe and have a bit of hot water!

  • @nwstraith interesting, run a line of them along in the direction the sun travels. all day there woudl be at least 3 of those bad boys kicking heat into that pipe! genius!

  • Reminds me of an ex girlfriend.

  • Amazing!

  • You just turned water into fire.

  • We need more people like you here in Cancún, México. Do you want to come here to see all the people that would love to implement many of your ideas? :D You could be amazed. -I'm one of those-

  • The only problem : we kind of have our sun stolen from us for several days now. The Sun seems to be shining so rare now :( I was puzzled that the plastic didn't melt...

  • That is Crazy Wow...

  • Very clever Dan

  • That has got to be the most clever thing I have ever seen. Great thinking out of the box.

  • The camera person appeared to be looking into the sun - not recommended.

  • Boy, that would beat the hell out of rubbing two sticks together.

  • Why cant i watch this on my phone

  • @linutas pay your bill

  • I repeat, don't leave these things laying around in such places like on top of speed cameras.

    You'll annoy the local PD.

  • so simple, yet so effective, amazing !

  • Pretty cool! 

  • Ingenuous. I've seen them made out of shaped ice before.

  • Great video, Dan! Thanks for posting this, Man!

  • That is some MacGyver stuff right there.

  • This is actually VERY cool and creative!! And, uh....10 cents is approximately the price range I've been searching for!!!

  • cool!

  • awesome!

  • That's a very good idea. Just another reason why I love youtube so much.

  • now thats cool!

  • If you filled it up with some clear resin of somesort and let it set, would it make a good lens? if so it could be angled like a fresnel etc.

  • very informative

  • Wow, that is fantastic !

  • you can do that with a condom, no joke

  • clever !!!

  • Dan Rojas, you are the Bear Grylls of solar power survival.

  • @chrisgrizle "Solar Power with Dan Rojas"

    Can I call Discovery now?

  • clever using water to turn saran wrap into a lense

  • OMG 10 Cent is like 10 pennies or 1 dime or 2 cans!

  • @rBlobify more like 1/4th pound of cans.

  • Way to go! Fire from water! I am putting clear plastic in my survival gear. Ofcourse your in FL, and I'm in WA. All I'll probably accomplish is rain water collection, lol!

  • Awesome!
