In this video we will have a closer look at a fake thermoelectric generator and find out exactly why it can not charge up a smartphone like advertised. While doing so, you will learn quite a bit about Peltier modules. Afterwards I will then show you how to create a real thermoelectric generator that can charge up a smartphone through the power of tea lights and ice water. Let’s get started!

and what about the peltier module wiring through series and parallel connections
doesn't one make the output higher than the other ?
Hello GreatScott,
how are you doing?
I hope my next description doesn't pollute your pretty mind,
my idea for this is to use a joule-theif circuit to boost the 0.09 volts of the named generator (the single peltier module one) to a proper 4.2~4.9 volts then using some other booster circuit to boost the output voltage to a proper 5 volts signal to use for something useful like charging a smartphone or powering a Bluetooth speaker
if you may have tothanks for reading and hope you are doing well.

Would using salt on the cold side provide any benefit? It would increase the cooling rate, would that enable more efficient uptake on the hot side? It's already splitting hairs at this point since you would not use TECs for any serious power production.
Would putting the tea lights closer to the hot side improve the performance, assuming you can keep the cool side cool?
De hecho entre en su pagina para criticarle por poner un video fake jajaja. Pero no vi el video, supongo que lo abra eliminado. gracias por este video.
7:10 why didn't you just weld them together
I want to see what like 20 of these things can do with them new super capacitors super capacitors.
Make 4 sided boxes with the plates and stack them 4 levels high for a total of 16 plates.
Cut a square hole the same size as your TEC box stack and water tight glue it in place.
Fill the cup with ice water and raise it up off the table about 4 cm with 3 or 4 little objects.
Place a single candle beneath it.
I think we need to make micro heat pipes to upgrade out TEC modules
Why not making a A/C out of those peltier 👍
I am going to tech builder channel and spread hatred hahahaha….small price to pay for cheating
Aluminum oxidizes and develops a light oxide coating in the presence of oxygen within minutes. So you need to chemically remove the oxide with a wipe-on oxide remover before you try to Aluminum-Solder Also, I believe there are peltier TEC units designed as generators — not sure what the difference is exactly but they can handle higher heat exposures.
With heat on one side and cold on the other I find myself curious what could be achieved with air conditioners. Lol
I get that you believe this isn't FAKE, but yours is just equally FAKE. You basicly put six of them in a serie and used another powersource in the form of ice wich in time costs energy to make.. Nice tweaks it can be way better using copper heatsinks and closed walls on the hot side. 1 candle might do the trick again 😉
If you want a reliable maintenance free power source and you have a hot spring, this would work. What else could give you electricity for 1,000 years that doesn't involve radio isotopes?
What wood the volt have been if you raised the flame closer to the heat sink with only the 1 tee light? What wood the max volt be able to produce?
Maybe he had the candle closer to the generator, but lol he private the video but really, who cares becasue he still got views = money
You need to meet the guy selling Quanta Magnetics
I think there has been large improvements in the efficiency of these in general as well as models specifically to generate power instead of powered temperature transfer.
There's even a commercial product about the size of this that claims to generate 45 watts. Maybe it's time to revisit these things?
What happens if we use peltier module shed house instead of tin shed house.
In a snow fall area .
Can you pls make a pcb etching shaker and a magnetic stirrer
A bit late, but you should have use acid on the joints you want to braze to remove oxide layer
As a career EE with >20 years in RFIC design I can say you totally NAILED IT!
The fake one failed a freshman physics analysis big time…calculate the energy available from the tea candle flame (old school bomb calorimeter), account for low efficiency of Seebeck Effect and it is no where near the amount of power (volts * amps) needed to do a legit charge. 5V @ a few mA probably won't even power the charge controller in a cell phone, never mind charge the battery.
Who has a sustainable supply of ice in a survival situation besides those with a constant source of snow? It takes electricity to make ice.
Ah, if you want to "hard solder" aluminum – you need something better like Techno-Weld (yes, strange name, huh?)
Otherwise it's welding that is required..
You used the wrong thermoelectric modules. TEC (ThermoElectric Cooling) modules are optimized for generating a cooling effect by applying an electric current to them. TEG (ThermoElectric Generator) modules are optimized for generating electricity by applying a source of heat to one side of the module while cooling the other side of the module. What you should have used is the TEG 1848 module.
Great video.
Much appreciated!

Very Thanks Scott, this is very useful information!
I've made the same experiment and I can confirm – no chance to charge up the phone this way. The missing part is a capacitor. With the one peltier module and good capacitor – you can make small light for short time, so yes, quite a survival thing. Now – scaling up with the mad mind – using 500F capacitor you can make a phone charger BUT you have to charge the capacitor up for a few hours or days, the same way the solar charger is working in Ireland 🙂
