FRESNEL LENS SUN COLLECTOR Heating a Swimming Pool with the Sun Solar Swimming Pool Heater
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.
Agreed:-)
Thank You for the comment.
o yes it dose and it works ! tks!!
Mike!!!
This would work best if the bottom of the swimming pool was covered by a giant copper heatsink, but had a glass surface (to stop people’s feet getting burnt), with holes in the glass to allow the hot water to circulate through the heatsink.
Hi Dan, Always enjoy your videos and also appreciate that you now use a tripod.
Following your acute perception of the EXAMPLE given, did you realize that it would not work at night also? His videos are more than interesting, they are very informative if you pay attention. I think those black shapes on bottom of the pool were doing what you so sharply suggested after watching the video. Ha! I’m not really that serious.
Love the refracted light mixed with smoke from the wood, amazing effect. Amazing refraction too!
I wonder why pool owner don’t just attach a equally wide swatch of black rubber (or something flexible and heat absorbent that wont leech chemicals) to their pool cover?
The black mat separated from the pool cover itself by several feet of connecting rope, it could sit in the shallow end, and be “rolled” up on top the pool cover (a white underbelly on the mat would make it indistinguishable when rolled up.)
aaaaaaaaaaah! it’s so frustrating to watch you try to focus the lens continually for 3 minutes!!!
Why can’t you edit this out?
You owe 3 minutes of life to every viewer
Light show:-)
awesomee ideas!!
I don’t think you’d need the glass cover. The water would be sufficient to cool the heat sink. You could have a black (classic oil treated finish)
Presumably, the glass cover would be there to stop people from hurting their feet on the sharp edges of the heatsink?
That demo was using a spot fresnel, right? Not a linear.
Yes, this is a spot Fresnel Lens. Linear lenses work best on a long pipe.
music from sxephil jerks lol
You people ROCK! Excellent video library!
Nothing better than something other than those darn humans, and how much money they can make on wasted resources! Peace!
PEACE!
im taking that to dragons den
would they get burned by the UV rays? they should have a separate little area that has water circulating but is closed off from the rest of the pool? ya?
dragon’s den?
its a canadian show where people pitch ideas to rich investors..
dont worry, i wont
originally english
Or just paint the pool black.?
I guess.. if you want a big black pool.
A downside to that might be that the black wil discolor not very uniformly and more quickly, looking patchy. Also, metal closer to the surface might be a better heat sink than a black pool floor.
Anyway, QUIT WALKING ALL OVER MY DREAMS MAN!!!
Yes the pool does go patchy and doesnt look too good, just a thought, keep your dreams alive. MAN!!!.
