The sleeping bag that charges your phone while you sleep

These things look like huge ads to me, they remind me of the clothing in "Idiocracy". That impression is increased by the fact that they're currently not all that useful: 8 hours sleep for 11 hours standby means you still need to charge normally, so you might as well just stick to that. Of course, this is going to become better and better, but right now it strikes me as a marketing gag more than anything else.

It almost certainly is, similar to Vodafone's solar charging umbrellas that they took to festivals[1]. Having seen the creator talking about it they're entirely unviable commercially, and were incredibly fragile.

As if anyone has ever had 8 hours of sleep in one night at a music festival...

Yeah, awesome to have technology that extracts (pumps) heat out of the sleeping bag, that sounds really intuitive.

I thought the point of sleeping bags was to trap the heat for as long as possible, insulating you from the cold exterior climate?

Exactly, this makes the sleeping bag less comfortable. It doesn't actually pump the heat though, it flows from hot to cold on it's own. It's actually like a turbine that turns the flow into electricity.
