50 Watt Thermoelectric Wood Stove Generator

[kistuszek]

The stove could suck air through the cooling fins to make a better cooling and to re-use some heat.

Wouldn't H&A be cheaper if you just use geothermal at say 8 to 10 LF dig? A VDC fan powered by 12 VDC batt stack charged by a combo sm. wind turbine / solar panel would work all nite. Seldom w/o sun or wind so charge is continuous. This sys. also uses a large diesel engine style radiator mounted via box on existing FAU system in attic / basement / etc. You just gotta make the effor to dig the trenches, run the S80 PVC, fill with H2o / antifreeze variant, etc. no temp variant at 10 ft. deep

The beauty of this is not how efficient it is for heat to electricity conversion. The beauty of this is that if you are heating a house with a wood stove you can throw one or two of these on the stove and charge batteries. Think ice storms with two or three weeks of no electricity. Also a good option for as a supplement of PV panels in inclement weather. Efficient to power them with a wood stove is not the issue. The issue is use heat being produced for another purpose.

[Mrinfoone]

why the radiator. don't need the max heat a viable?

[flesvik]

So you are putting out about maybe 7 000 W of heat from the stove and then you get 50 W electricity out of it..... Wow what an effeminacy.

[Super98chevy]

@flesvik Epic fail ^

effeminate — adj

1. (of a man or boy) displaying characteristics regarded as typical of a woman; not manly

[flesvik]

@Super98chevy yeah pointing out typing errors instead of addressing the argument. THAT is an epic fail....

[ackkipfer]

@flesvik Yeah, but he is right...

he is not bitching about it...just trying to help

Also...

better then say bad stuffs...

[AircondGypsy]

Co$t may be the limiting factor for me but I like that they have no moving parts to wear out and as I'll have a constant heat source in the 450 * range these units might be just what I'm looking for. thanks for the demo.

[evilspiritchild]

Your better of having the unit mounted under the a stove to improve its efficiency and not surrounded by heat after all hot air rises .

[Duckyistrippin]

@evilspiritchild the stove isnt as hot on the bottom....the whole point here is to heat the generator so it can do its thing.

[amos033]

Excellent video showing us how a TEG can be used with wasted heat from a wood stove to charge a battery..well done.

[hannas1234]

Thats pretty neat, but what good is a wood stove on the back porch?

[vampov]

No offense thermocouples rock. But if your going to do that you might as well have a steam turbine and heat water with that stove it would probably be a better use of the joule production

[marmaladekamikaze]

@vampov

I don't think a steam turbine would be a DIY project for most guys man, however you're absolutely right, this guys setup is pretty inefficient. A Stirling engine would be far better.

[eastrockaway11518]

Is this guy a mime?

[AnnBearForFreedom]

@eastrockaway11518  I don't know what he does for a living, but youre certainly a jerk. If you can't appreciate the technology he's demoinstratng, fine...but you don';t have to make nasty comments.

[orbit9a]

So this can almost power a 60 w light bulb??

[ursmarts]

thats pretty good for using waste heat

[AnnBearForFreedom]

@orbit9a or it CAN power 2 25 watt light bulbs! or, better yet, 4 12 watt CFL bulbs! or many million LED bulbs! okay, never mind the LEDs (unless youre lighting a dollhouse)...but the CFLs are bright enough to make a big difference. But I think the bigger payoff might be to charge 12 volt batteries and run 12 v appliances. Think big!

[chipus2]

Put the reservoir and radiator higher than generator and discard the pump.

[tubefed420]

and you can power what with this?

[brodie1709]

@tubefed420 the water pump that cools it.

[tubefed420]

@brodie1709 Would you be able to also power some leds or anything useful? or is this just a demonstration that it works? Thanks

[brodie1709]

@tubefed420 oh i have no clue im just saying that it looks like it is doing nothing but running itself.

[pushka48]

how much it will cost to you buy a sistem like that

[field16]

Looks nice, but I would like to see how you calculate 50 Watts on that small strip.

[HomeDistiller]

@field16 and i think hes mute

[moscowfragfest]

@field16

At 0:49 you can see there that (4) TEC units between each set of bolts, so in total there are 24 units. Each unit can supply ~2 watts. So that would be about 48 watts.

[field16]

@moscowfragfest Thanks for your explanation. When I tested a TEC, I got about 70 mW (or 0.070 Watts). My results were far from 2 Watts each. Maybe the TEG's he is using are of better quality (TEG's are supposed to be better than TEC's) or he is assuming a greater temperature differential than I used... or he did not get 50 Watts. I would request that he show the actual Watts using a meter and hope he is really getting such a good result.

[moscowfragfest]

@field16 np, I just saw this message, 2 watts is assuming you have a heat sink/fan set up or are water cooling it.
