Peltier Energy Generator. Solar pannel alternative.

I used a Peltier thermal electric cooler and a satellite dish to generate electricity. More info here: http://filear.com/?cat=48

HI there

I think you need to cool your coolside more.

What you can try is to attach a metal bucket ( aluminum ) filled with water to keep the side that is facing the sun right now cool

That will give you a bigger difference in temperature and therefor greater output.

Keep us posted

@rikkiesix I agree, I have also aquired some better heatsinks to play with. I will try to make time to experrement some more.

[BryansU2B]

why not use a solar panel in the center where the peltier device is.

Mirrors are probably cheaper than more cells right?

[filear]

@BryansU2B You are correct in thinking that you can increase the output of a PV panel using mirrors or Fresnel lenses, the draw back is the panel can over heat and burn up if you overdo it. Good idea though someone should do some experiments.

[electrodacus]

You can use a heat accumulator as water or solid like concrete and then the advantage is that is easier to keep a constant temperature and lower so you will not melt the Peltier also you can generate power all the time even at night or cloudy day if you have sufficient thermal mass to accumulate the heat when is sunny.

So this is an advantage since you can not store light for solar panels but you can store heat for peltier.

Your fan and heatsink are black and they are being irradiated with sunlight as well. You need to put a white material over them to shade them. Then you will get a much larger differential of heat and therefore more power. Try this again and make another video. Thanks

or a boiler with a steam turbine ,stirling engine needs to be cooled too though, also i think you need a better cooling system ,a bigger heatsync or a water pump and maybe a cpu waterblock or a home made equivalent ,i bet that would up the juice a bit, but im not sure if there is a better TEG,,so are they all peltiers essentially? or are there ones that run on heat alone and dont need cooling on one side?

[bulletproof2353]

@filear so are peltiers the only TEG"S? i mean are there any that you can just heat,and dont need to cool 1 side?or are they all just peltiers running in reverse?

i was thinking of doing something similar with 2 fresnel lenses i got from old rear projection tvs and a sun tracker to keep them pointed and focused, but i see that the peltiers wont work thanks to your video, way too inefficient, but i bet if you used mylar on that dich you could get the temp up to 4or 500 and use a stirling engine

[seennlisten]

would you tell me what to do with the yeeky paste in the square area of the cooler?

[HarryHydro]

Cool stuff. We use TEGs where we have no electric. A natural gas flame heats the one side HOT. A hugh heatsink dissipates as much heat as possible. The heat sink is by far the largest component. The electric regulator part is a compromise. It holds a load across the peltier to move just enough heat to the heat sink to keep the solder from melting. If you pull an external load, this regulator works like a boost converter. It's good for 20 watts or so.

[columbuskiter]

Cool stuff - did you try this with the fan running from an external source to see how large of a temperature difference you could achieve?

[91thpe]

Try Corsair Hydro H50 as a cooler :)

[lennchma]

@lennchma I mean you should protect HOT side from additional warming from the sun. Try some cardboard or something,.

[lennchma]

your black radiator is getting warm from the sun, so a thermal difference is getting smaller. You should protect cool side from the sun.

aww i wanted to do this too, with iron and copper wires wrapped together on a large satillite dish, like 10 ft :) there should be some energy from that baby! good job. if u got time look up the iron copper thermocouples, the first real heat sink energy producers, from simple materials..
