FRESNEL LENS SOLAR HOT WATER, Heat Solar Pool Heater Solar Swimming Pool Heater
greenpowerscience.com This is a large Fresnel Lens focused on a copper tube with a 12 V pump (powered by two 6 watt solar panels) with water circulating through the unit. Water, seven gallons, was raised from 63 F to 106 F in one hour. It is not super efficient as heat is lost at the open top of the glass tank. This is designed to illustrate one method of solar heating a swilling pool with a Large Fresnel Lens. TESTING HDD AQUA BLOCK.

They are very frosted and only produce a little warm area.

Very effective method. I must admit I did not understand the concepts behind it, but very fascinating.

Have you considered combining this with a thermoelectric generator of some sort? Would it be more efficient or would it be overkill?

It seems like the sun moving through the sky would cause the focus of the lens to move to different parts of the equipment and destroy it. I also notice that you seem to be a pyromaniac since you love to put pieces of wood under the lens and watch them catch fire 🙂 Anyone else notice this?

It’s so nice to see your work, something practical that really performs ! So many of these videos are people trying to hustle others by selling plans to make a car run on water etc. So, thanks. now, quick question : When using a lens like this, what are the reqirrements for tracking the sun ? If it is set up in a fixed position, will the output be ok without that ? Otherwise, I will design a system with servo motors to adjust it … thanks so much again, especially for input output data !
