this is a completely different use for the lens, but i saw some youtube videos not too long ago about people making soda can heaters by removing the bottoms of cans and caulking them together to make tubes, where the lid of the cans compartment it so the sun has time to heat the air inside. just painted black the system turned 40 degree air into 200 degree air. i hope you see where I’m going with the focused lens… i also saw some of water heaters working similarly. hope this sparks good ideas!

@rainbowsalads that comment was meant for the latest video were the cable was heated up and melting due to the added mirrors.

mains cable = lower resistance .thin cable is great for making a nice filament , but will completely rob/convert your energy to heat, maybe even light…As we see here, smoke, at least 50 percent of the energy was wasted! Probably fortunate, in that the internal circuitry was protected due to this naf cable.

What would be the potential for combining such a panel with e.g. solar pool system to solve all problems?
By that I mean run water through capillary pipes behind the fresnel focused solar panel as a heat sink to dissipate the heat and at the same time create hot water for your pool/shower. The idea being to combine both panels into a single unit.
I’ve not seen any vids on making your own solar water/pool heating panels… do any exist, is that even feasible?

five stars
uh, wait, there are no more stars

Great stuff dude. Thanks!!

array of computer heat sinks?

Yeah. You do have a good Channel.

Thank You!+++++++

Greenpower science is awesome!! My favourite channel. : P

I know that some are wondering how to couple the two? I know how.

@brianwesley28
With the funding, I could put something like that into production in short order. I design a lot of things in my head because I don’t have the money to design them elsewhere, at present.

The Peltier cells are generally used for heating and cooling, but when they are exposed to a temperature differential, they will produce electricity. That is a form of cooling if one is converting heat into electricity, with the added benefit of producing additional electricity. I’ve also thought about fresnel lenses directly on Peltier cells, but the ones designed to withstand that much heat are rather expensive.

I’ve thought about doing something like using a fresnel lens to do what you’ve done, while coupling Peltier TEC’s into the process to help bleed the excess heat of the enclosure, while producing additional electricity using the Seebeck Efffect.

@gymsim most Fresnel lenses will bend like that. Not sure what the point would be in bending it. That makes the optics useless. I have seen patents for the bending? Some think it offers and endless tracking to a perfect point.
I have some Fresnel lenses that are made out of lexan, fresnel Rubberized but lens is bullet proof. will cut but not puncture.

Hey Dan. Nice idea with using the lens! There are some applications on the web for a ‘stretched’ Fresnel lens solar concentrator for satellites. The lense material is not suppose to be as fragile, but I’ve found no evidence of it actually being used. Are you familiar with any of those experiments or the results?
June 10th, 2010 at 10:54 pm
put a solar water heater rig to cool the panel and heat or preheat the water too.
June 10th, 2010 at 11:00 pm
Another great video Dan, but, one question regarding the use of either the mirror or fresnel lens. Wouldn’t either require some sort of tracking system to keep the panels pointed at the sun or would this method still give the same results as the sun moved across the sky.
ThankX again

Get a Heavy Duty PV plate!
There MUST be some manufacturer that had an idea to produce a specific PV plate to that purpose…
Any way, in these day, PV aren’t the better solution for energy. The efficiency still too poor.

cool. i wanted to do this kind of test myself.
for cooling i would use a natural circulation copper piping that would also heat up some hot water for your house at summer. and at winter ofcourse you have to drain system because ice could damage your system. I think its worth to try since you shown >30 % more output

true, but still pretty bad ass. lol

They have an elaborate cooling heat sink system.

isreal has focused ALOT more light that you have there on a spot roughly one square foot…it didnt melt. its on youtube . search isreal solar farm

3. There was talk of a film of water running over the cell increasing the amount of light energy hitting the cell. It would seem to me that unless a larger surface area of water was used to form a lens, no real gains could be had. Am I wrong?
I basically am going with the majority here. I believe running water over the components to cool them and use the water for household hot water. I would say experiment with running it over/under/both and combining that with the use of heat sinks.

Hello Dan,
First, great videos! I love what you are doing. I came across a video of yours today and have been watching them basically non-stop since. I have read all the comments here and I have a few questions that I do not believe have been answered. I hope I can start a discussion about some of these here.
1. Is there an optimal temp for the PV Cells?
2. Accounting for the cost of the lens vs. cost of pv cells, and the % output increase; is it efficient to use the lens to increase power?…
