just spray paint a radiator black and run? your pool water through it.

How about? focusing the lens on a 1" diameter copper pipe with the pool water flowing slowly through it via a small pump for better heat transfer before the water flows back into the pool?

You? have to focus the light on a dark mass inside the pool, works like a charm.

Hi @GREENPOWERSCIENCE - Thanks for taking the time to reply to my questions. I was still wondering if you? could answer the last question I asked regarding how much of the pool - (a 15 foot above ground 4 feet deep round pool) - would have to be black and how long would it take to heat it up a few degrees? I'm considering putting some 4 foot round black vinyl on the bottom - as long as it sinks!

@EDDIEPIRRERA sq M of light is the same, Fresnel lenses concentrate so 1 sq M focused on a dark object is the same as 1 sq M of black material in a pool without the need for tracking. I could sell? a lot more lenses if I pushed the pool concept but simple black objects are better. If the sun reaches the bottom of your pool, sink some black plastic to the bottom. Make sure no kids get tangled up in it. Plastic works as good as metal in water.

Hi, I'm interested to know a little bit more about the comment you made at the end of your video. You said that something black at the bottom of the pool - if the same size as the fresnel lens - would produce the same amount of energy as the fresnel lens. I have a small 15 foot round pool that I'd like to heat and was wondering if you could you explain this concept further? Thanks! PS - would you have any idea how much of the pool? needs to be black and how long it would take to heat it up?

Hi, can you tell? where you purchase such a large fresnel lens? Thanks

@icelez ? yum, smart thinking

its a? small pool my friend! i am too big for this !! ;)

Also, Perhaps a small "waterfall" or a couple of sorts could collect heat with a solar tracking rotor and target the lens on the fountain and a 12v module? or more can provide a steady trickle or flow into the pool. No sun burns that way too! I swear she was just swimming and the fresnel lens melted her bikini off.. officer!

the problem with the burning the table is the focal point is on the table not in the middle of the water? you can boil water with any lens
By: AreaQNH870. on 01 Feb 11, 19:34:11
Solution: Make bottom of pool black. Or blue. Or? anything non reflective.
By: LizzyAston. on 31 Jan 11, 22:54:04
in? theory, you could point this at yourself whilst under the water - you'd get a tan but you wouldn't burn!!
