marshall min: do you schematic of the converter used?
George Louis: what is the difference between the two sides and which side has to be
heated and which side has to be cooled to generate electricity?
imtiyaz ahmad: sir how i can make this peltier systm,plz help me
Random Man: You could stick 100 of these on the back of a solar panel and use them to
pump the heat away from the PV and use the shaded side to cool.. 3
advantages, 1: Cooling hot solar panels increases PV efficiency, PV can get
real hot in summer. 2: Cooling can allows more light to be focused on PV
allowing an increase to the traditional output from PV. 3: The ability to
milk another light frequency (Infrared) source PV fails to convert in the
process. If you could stick a 100 of these = 60 watts?
George Louis: I ordered some of these from China. (that's the only place that makes them)
So when I get it how do I plug it in?
63saif: could u plz tell me something about its cost....because i want to generate
about 200w could u plz tell that how much cost it will get and also what
should be temp. range on both sides? w8ing for u reply
superdau: Yeah, but put a heat-into-steam-into-turbine-to-generator onto a
satellite. Or build a reliable heat-gas-sterling-generator the size of a
Ryan Willis: It doesn't really matter- if you heat the wrong side you will get the
opposite polarity on the wires and that's all. Just measure with a meter
before you hook stuff up.
T3CHNOTURK: generate licht into licht :D
Chad Harrington: Something mirrors could also do... for allot less money :)
Guile Williams: Those peltier modules are fun to play with. Consider using a PC case fan
for cooling as it uses less power. I was able to get 5V 2.1A from my module
using a portable cooktop stove for the source of heat (to measure the
performance of the peltier module) and a decent CPU heatsink w/ fan.
Larskro: The efficiency is max 6% at peltier elements. If you keep a 60 watt element
against your skin and keep ice on the other side for cooling, your skin
will quickly become cold, and yoy have electricity only for a moment. It
required a lot of heat / cold. If you have a wood-burning oven, it will be
good. It would be better to connect the 6 x 60 watts in series, then you
have 6 to 12 volts. A peltier element does not tolerate heat above 100 c,
or it will melt inside.
George Louis: What the hecks a meter? You mean that if I heat the other side then the
electrons will flow in the opposite direction and it doesn't matter if the
electrons are going forwards or backwards?
theoutmoreproject: why are you plugging it into the blue battery phone charger? why have a
battery at all?
brian burnett: this Is No Fake. , just Normal test. Far out. yeah alll true.
Larskro: Search on -- ebay.com -- (Emergency AA mobil charger) and here you can buy
the inverter. Works from a AA cell 0,8volt in and out 5,5 volt. You need a
resistor about 300 ohm in series with a diode. A white diode need only
2,9volt and a red ned 1,8 volt.
Zach Beydoun: you can buy a peltier device on ebay for $3
Ryan Willis: if you can convert 2% of the heat generated from a candle (candle makes
70-80 watts and one lumen) to electricity, you can power a 1.5-watt LED
which will make 80-150 lumens. Candles are really not efficient light
hooXpoo: Nice design:) Looks like a very nice phone and more charger. Thanks for
Ryan Willis: That is the problem with these things, they almost always put out less than
5 volts so it's hard to do anything with the power they generate. I'm
planning on making a version of the device in the video but using a
dc-to-dc step up converter to power a single 1-3 watt LED with it. Send me
a PM and I'll give you a link to what I'm going to use.
Larskro: Hej There is not a battery in the phone charger. See the wire going in.
Larskro: Hej There is not a battery in the phone charger. See the wire going in.
Pașca Alexandru: Where did you find TECs at $3.5? I can't finf anything below $10 here...
Ryan Willis: I correct myself: a candle puts out a whopping 13 lumens. Still only an
efficiency of 0.16 lumens per watt. Modern LEDs are capable of 150 lumens
per watt or better.
marshall min: what was the converter u used??any circuit diagram or components
Azazel ciort: Wow, you burn more electricity to make less energy , we suppose to think
that smaller quantities of energy is better, you genial genius.and don't
make as dumb
Lodoz: Why do idiots keep posting these stupid fake videos?
Larskro: Hi, 1pcs 60 watt peltier cost 3.5 $ and give only 2watt out. With a
temperatur difference on 60 degrees.
thesituashawn: so why have it at all??? fail imo
overunitydotcom: Well done ! Nice converter ! Where did you solder the Peltier element to ?
I broke my Peltier element by heating it too much, so the soldering points
inside the Peltier element got broken and melted too much.... So be careful
with too much heat at the junction points... P.S. How much current cam you
draw at & Volts from it ? Many thanks. Regards, Stefan.
brian burnett: Yes Very Small power supply ,,isnt it. i got a dozen and still think its a
waist of time Now after testing One, but when i get the full 18 units of 40
mm High Temp TEG Very Soon ,So I hope i can Get good Amps on my test. With
Yours Im Wondring the Top Vltage and Amps. Have you Cheaked.
Random Man: But doesnt a candle output more heat than it does light and leds outputs
more light than heat? He aint burning no electricity sonny, he is just
taking advantage of the utter inefficiency of one device, "the candle"
converting for use to a more efficient device the Leds. He could improve
the passive cooling with huger heat sinks and his results would improve.
Larskro: You can apply Materialer as du need on "ebay.com ``
SurvivalGrounds: woah COOL.. this gave me so many ideas. a wood burning stove covered in
these could provide quite a charge!
Larskro: @overunitydotcom It gives 1.5 volts at 0.25 amps when the differential
between the cold and hot side is approx. 40 degrees censius. Most of the
energy will be needed by the engine for cooling. At a temperature
difference of 60 degrees delivered approx. 2 volts and the current is 0.5
amp = 1 watt
Larskro: Graphene in new ‘battery’ breakthrough? Mar 8, 2012 58 comments
Researchers at Hong Kong Polytechnic University claim to have invented a
new kind of graphene-based "battery" that runs solely on ambient heat. The
device is said to capture the thermal energy of ions in a solution and
convert it into electricity. The results of, such a device might find use
in a range of applications, including powering artificial organs from body
heat, generating renewable energy and powering electronics.
Ryan Willis: I meant an electrical meter, one that can measure volts and amps and
whatnot. You are correct: if you heat and cool the "wrong" sides, the
electricity will just go the other way so black will be positive and red
will be negative.
TheMrBeaton: He is only using it as a voltage converter. This would have been obvious to
you if you had read the description and the comments. And since the only
sport you seem to excel at is jumping to conclusions, allow me to
participate - you are either A) American, B) Under the legal age to attend
school, C) Generally dense, or D) All of the above.
marshall min: where the fan get its power source???
Larskro: Hi. A white leed need 2.7 volt to light, a red led only 1,7volt . If you
have the 2 peltiers in series, the voltages will be higher. The blue
converter raises the voltage from 1 volt to 5,5 volt so that the 12 LEDs
alissondjean: @SurvivalGrounds How about the SUN my friend! it has been developed before
(you can check it at the NEW ENERGY SERIES) imagine a bigger version placed
under the sun! WHAT A GREAT EXPERIMENT ! Thank you so much for sharing! is
there any prototype i could by so i could study it? please and thank you !
restu pamungkas: Good job. Is reall experiment
91makarov: sir,im buying 2pcs TEG1-12710.but until now.i still cant light up even 1
LED.can you help me with this problem?
cmlundin: You could also build a voltage multiplier circuit. You will loose amps, but
it does bump the voltage up to a usable level.
Yefatbastard: The man with the million dollar question.. I was not there to see his
setup.. but based on his comments on the power output of his TEC/TEG and
that the fan was running before he even puts the candle under the chimney,
I would say it's the battery in the "blue converter" I would ask the poster
to show the setup again with a look in the blue bit included.. If the
poster deletes this I will have my answer and will send it to you in a
thesituashawn: do you feel good about yourself now? did you pat yourself on the back?
someone give this guy a cookie please...
cmlundin: a small amount of electricity is diverted to power the fan from the thermal
Paxmax: oh geez, peltier are 6% effective? I knew it was bad, but 6% !!!
wahahahaha. Then any heat-into-steam-into-turbine-to-generator is WAY more
effective. Or heat-gas-sterling-generator.
