I have been looking around Youtube for various ways of generating electricity off grid. I came accross this video from MrTeslonian. About the thermal properties of Nitinol Wire and Copper Wire which looks interesting. Does anyone know if this really works ? And i'm interested to know what sort of amp this could generate ? Techman this could be useful to you if this principle works ? You could produce electricity from your wood burner to charge your batteries if this Nitinol Wire and Copper Wire would produce enough amp ? Here is a link to the Youtube video check it out

I cannot currently watch videos, sadly. I think my phone bandwidth is maybe limiting me.
But I have seen such things before. Normally they do produce some limited power, but not enough to be really useful, from what I have studied.
I am leaning more along the lines of a thermoelectric generator using peltier elements.

Re: Nitinol Wire and Copper Wire ?
You notice he says at one point "Mili-volts". Also, he never shows you the current or mah (mili-amp-hours) this produces. These devices are common, in a furnace or water heater, it's called a "thermo-couple". He got an average of about 5 milli-volts. That is .005 volts. So, if you put 1000 of these in series with just the twisted portion hot (maybe the stem needs to stay cool??) you'd have 5 volts. To charge a 12v bank, you'd need about 3000 of them to get 15 volts. And, who knows how many mah that is putting out. If it were 10 it would surprise me. 15 volts at 10mah would only be .15 watts. If it's putting out 100mah or .1 amp, that would be 1.5 watts charging power. As you can see, there isn't any potential here other than maybe to charge up a solar path light.

Re: Nitinol Wire and Copper Wire ?
Hello techman yes i agree with you most of the thermal electric generators that i seen produce voltage but not many amps I will keep an eye on MrTeslonian videos & see what his results are if they turn out interesting i will try some experimenting of my own with Nitinol Wire & post you updates on how things go

Yes, Dave, I think you are correct. These things are fun to play with and light up an LED.

Please let us know how it goes.
