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.
why not paint the copper black? MAXIMUM EFFICACY
Excellent idea and like that blooper too, keep up the fine work.
@GREENPOWERSCIENCE I like the black plastic idea too, but would that end up being something requiring periodic replacement in a the high desert where the UV can be really strong?
@diamencik1 its actually probably from a old tv… check out kipkay’s solar death ray!
@bashiryu sun, steam, generator, batterie, electricity.
more carbon tax
This is brilliant Dan, brilliant….
theres a bug on your right at 3.31… 🙂
lool bloober!
what’s the ideal height for swimming?
at 3:33< something ran down that big palm leaf ting in the back, lol
@bashiryu Heat water to turn a turbine.Directing the beam at a boiler. A telescopes gps could be used to keep track with the sun. The heat is incredible so boiling water is easy. This will run a steam engine. This method here could heat your house with in floor heating.(much smaller that the glass tube systems).
I just got mine out of my 52″ Panasonic floor model 1985. Can’t wait for a sunny day to melt some concrete.
Mr Greeen, What is the real application for these FRESNEL?
in real world how this be used to produce electricity?
EEEEOOOOUUUUHHHH!!
Date one Latin women ** rockmycity.info **
30 sq. meters pool will absorb 30 kW without any heater. With your heather it will gain cca +2kW. Does it really make difference!?
3:31 look above and to the right of the copper appurattus and there is a small lizard crawling on the leaf!!
wouldn’t the copper that you are focusing the Fresnel’s light on be much more effective if it were black, rather than shiny? I would think a flat black stove paint would help to absorb alot more of that light rather than reflecting alot of it. Thanks for the vids, they are very informative.
lmao at the blooper.
Thousands of real profiles real Russian women gettop5.info
Lol, u used a computer water pump, tubes. And even looks like maybe a GPU heatsink to do this?
Combining Solar power with computer hardware… now you’re going RIGHT down my ally xD
I think you could use natural circulation (hot water rises) along with a slightly different configuration of tank and hotbox to remove the pump from the equation. I think the basic idea is have the tank ported at two different elevations, a high and a low. Water heats up in the hotbox and exits the higher hose, which displaces colder water from the bottom of the tank into the hotbox entrance. Good enough for nuclear reactors 😉
Do you have a computer program directing motors to follow the sun so I wouldn’t have to supervise the heating?
@bLuDcL0T What i mean – eg. a pyrex glass with the stainless steel wool in, with an airtight top fitted to the hose – hose goes into the water you want heated – the steam would pass through the water heating it. Extremely low-tech but it would be 100% green as no other power sources would be needed. Hope you read this, and try it sometime.
