FRESNEL LENS SUN COLLECTOR Heating a Swimming Pool with the Sun Solar Swimming Pool Heater

http://www.greenpowerscience.com/

This video show how a Fresnel Lens can be used to generate heat in water for a pool. It also illustrates the inability to heat water only. and the need for a dark target. The heat sink used in this video falls short of being a true dark object but the green color looked cool.

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?

@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.

This method of heating water with Fresnel Lens I would like to try it but I do not know where to get the Fresnel Lens Please help me Kindly post your comments

@cokerfarm118 Check our website:-)

what about heating up poision leeching plastics to swim in

[GREENPOWERSCIENCE]

They never get more than the water temperature. So it would only be an issue if you swam in 130f water.

Dan you are the man. Great videos as always. When do you find time to work and pay for your science park?

Hi, I wanna ask something, I have a project about how to use this fresnel lens but not for swimming pool, i wanna use it to heat the evaporating pond in the salt production, is that possible thanks...

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?

Go to solarsunpacifc website for best solar pool panel prices. We'll do our best to beat any price.

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!
