Why did I not think of this?

Clever idea. I wonder what kind of current she can get from the Peltiers with only hand heat. Also, I wonder how that current is affected by ambient temperature.

In high ambient temperatures, I’d imagine that current would drop off as the temperature differential narrowed. Over 99 degrees, would you be able to get anything at all?

That’s brilliant. Brings a tear to my eye knowing that there are brilliant teens interested in more than video games.

How about a video game that you invent stuff in it? lol

On a more serious note… The machines new we had the power, that is why the Matrix exists… Copper Tops… lol

That is really cool that she made that. Kudos to her. :slight_smile:

Yep :slight_smile:

@ Architect -

Sorry… I did not see your post about the flashlight.
I only found out about it this morning…

@ willgeorge - Oh don’t worry, there is nothing to be sorry about. ;D

[/quote]Ultimately that is a problem in that its the temperature delta that creates the power, so where this would work best, you really wouldn’t want to be holding onto a cold metal tube with your bare hand. That said however given she is only powering LEDs which are constantly getting more amazingly efficient. As for me I’ll continue to use my BioLite stove and Power Pot for my thermoelectric kicks. Certainly she is to be commended for a) thinking outside the box and b) designing and building it and those skills ought to be encouraged for everyone (why I love Gadgeteer for example). Perhaps the best thing she has done has made people think, ‘why didn’t I think of that’ (I know why I didn’t) and hopefully now they are thinking.

My sentiments exactly… :think:
