Ivan Cerovec: a bit silly, but stoves like that produce more heat in the exhaust than on
the casing,. why dont you make an exhaust that has copper pipes in it and
then use that heat to heat up the peltiers..
UofA RoadHogs: Cat got your tongue? Would have been nice if you told us about this setup.
Harmen: How much does it cost? What temperatures are needed for 50 watts? How much
heat does it transport? Thanks, really interesting!
brodie1709: @tubefed420 the water pump that cools it.
flesvik: @Super98chevy yeah pointing out typing errors instead of addressing the
argument. THAT is an epic fail....
blogobre: I'd like to know that too actually.
Insect0man: Show Me Da Amperes. Otherwise - NO SALE.
Paul Sowinski: @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.
gizmoguyar: It depends how you define efficiency. From the newtonian physics point of
view, sterling engines are extremely efficient. Or at least they can be.
But they're much larger per unit of energy output than other forms of
energy production. I guess that's why we son't see them in commercial use.
Tim Attwood: 200,000 hours
Jay Igaboo: Exactly! I have a remote weekend shack here in Scotland, and I am going to
try some cheap tegs for my 12v lighting. Thermal efficiency in unimportant
as any inefficency in the machine is heat-- what I ahve the fire on for
anyway! It's like a refrigerator in winter is the nearest thing to a
perfect machine- fridge keeps your food fresh and the evaporators throw out
the "waste" heat.
pushka48: how much it will cost to you buy a sistem like that
Insect0man: There's a "THERMOELECTRIC POWER GENERATOR TEG MODULE " on EBay for 7.99 How
does your TEG differ from those Peltier devices?
ursmarts: thats pretty good for using waste heat
gizmoguyar: That's true. But they *are* incredibly inefficient. I personally like the
idea of steam turbines or sterling engines.
naturalbornhazer: is there a step by step of understanding? anywhere along with a list of
Insect0man: "1. Peltier Effect: This effect introduces power to the module with a
resultant cooling of one side and heating of the other. These types of
modules are low amp (typically in the 6 amp range) and are designed for low
temperature exposure of no more than 70°C to 90°C hot side. Higher
temperature exposures will cause the module to either break apart, couples
joints to melt and are not good power generators!" Google "HOW
THERMOELECTRIC TEG GENERATORS WORK" ( and don't work )
jbiasutti: Condenser on the back of the fridge throws out the waste heat. But that is
oldford71: are these units still available?
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.
Charles Hammond Jr: When it's cold... there's no such thing as 'waste heat.' The fact that you
can use it for Electricity generation is a plus though.
ChicharonyPresidente: The truth hurts doesn't it? You are the bitch, it seems your video is mute
because you had you man in your mouth and couldn't speak. Yeap, you're the
bitch. And your video is a crap, this is still useless no matter how much
you want to insult other.
n5syr01: how effiecient would the cooling be if you eliminate the pump, and try to
use a thermal siphon effect to circulate the coolant?
ogi22: You have probably seen something like a Peltier panel (or similar thing
converting the flow of heat directly into the flow of electricity). Those
things are sometimes used in computers to cool down processors, also used
in small car refrigerators. Just in those last two examples they force the
heat transfer when current is applied.
djmaur: Would have preferred a narrative. Where this may have been produced for
someone that already knew what was going on, Youtube is a medium that
brings in those that may not know anything about what you have produced. I
leave this video without having gained any information.
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
orbit9a: So this can almost power a 60 w light bulb??
tzmdomeguy: If your radiator were mounted above the peltiers and away from the stove
(or even outside) the water would be naturally circulated by gravity. On
cold days your heat transfer, thus, electric output would be increased by
the extreme heat differential. Peltiers do not opperate on heat, they
operate on "heat differential". But to conserve as much heat as possible
you could blow cold air from the floor through the radiator. Any heat not
used by the peltiers would be put into the room.
field16: Looks nice, but I would like to see how you calculate 50 Watts on that
Luis Burgos-Jankovic: 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 .
Insect0man: You can find everything required on Amazon.com
sizemorej: 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.
BoobTubeBob: Thanks for taking the time to demonstrate , you sure get some loosers
commenting . If these punks mommy would take time to change their poopy
diaper maybe they wouldn't crank and cry so much . This is a whole new WAY
of thinking for a generation that's been spoiled ROTTEN with everything
handed to them but I see there's a lotta brilliant young folks too with
clear minds that use their brain for thinking insteada their ass .
kistuszek: The stove could suck air through the cooling fins to make a better cooling
and to re-use some heat.
Paul Sowinski: @field16 np, I just saw this message, 2 watts is assuming you have a heat
sink/fan set up or are water cooling it.
Hogwit: What is the real world power output? On that stove for example, minus the
power for the cooling system...what is the net? Probably less than 20
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.
tubefed420: @brodie1709 Would you be able to also power some leds or anything useful?
or is this just a demonstration that it works? Thanks
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.
blogobre: And the size of the TEC1-12709, Dimensions : 40mm x 40mm x 3.6mm. Since
they are pretty similar devices, I would have thought that was a good hint
for further investigation. The 'main' thing is they are rated for different
things, the TEC1 is rated for cooling, being the power required to cool and
the other the power generated. Since best case for TEC/TEGs [again same
thing really] is a 5% conversion of heat to electricity, you'll see why the
difference. Do look things up next time eh.
Insect0man: 15 Watt High Temperature TEG Panel Model: TEGP15 Retail Price: $79.99 VS:
TEC1-12709 Thermoelectric Cooler Peltier 90W 138.6Wmax Price: $10.99 Uhuh.
There's one born every minute, isn't there. NO SALE.
TheDarwitch: 200k hours or about 22.8 years and they normally come with a 20 year warr.
FixedByDoc OffGrid: on the TEG website for one.
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.
FixedByDoc OffGrid: peltier devices work on a different setup and are less effiecient. is all
im saying. if there is one on ebay for 7.99 then it is probly quite small
in the quantity of power and rate it puts out or something is wrong with
it. a good teg for charging 12vdc car batteries runs about $379. there are
cold versions and hot versions. the cold ones are way less effiecient then
the hot ones. this is all im saying. but hey if you found one for 7.99 and
it works for your needs then good for you.
chipus2: Put the reservoir and radiator higher than generator and discard the pump.
HomeDistiller: @field16 and i think hes mute
FixedByDoc OffGrid: yes it is measured by the wattage but if you have ever compared a 6volt to
a 12volt you would understand that the wattage can be the same but the
longivity and consitancy of it differ. there are two types of these. one is
based off of cold which draws very little power despite it saying it is the
same wattage and the other type draws power from heat. the hot version
produces more power at a faster rate. get a clue. buy them and find out. i
will not be responding back.
AircondGypsy: Co$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.
