Or in other words it would be possible to continually power an iPhone with the temperature difference and area available in a tent. I think the context is important to whether this is presented as something negilable or something useful. Though there is absolutely no doubt that we aren’t going to see extreme amounts of power from this in tiny devices.
- taneq 8y agoIt also depends hugely on the nature of the generator - if it's a flexible sheet which can be used to make a tent, then awesome. If it's a rigid sheet then you'd be far better off making your tent out of solar panels even if they only saw an hour a day of sunlight.
- tomtimtall 8y agoThey are not mutually exclusive though. And your tent would tend to have a higher temperature gradient during the night when there’s no sun.

- cornholio 8y agoA 2 cubic meter tent has a surface area on the order of 10 square meter. The temperature differential can easily exceed 10 kelvin during a cold night, else your face will freeze off. So the potential for the application you cite is whole watts of power, enough to recharge a phone or a lantern overnight. (though, at current silicon fabrication costs, the price would be prohibitive)
