How are they planning on powering these devices? The original article doesn't mention . . .

Solar seems the most obvious choice (to me).

Solar in Scandinavia?

One of the real problems with solar is that you need a lot of surface, which means more weight, which means more power needed...

Solar cells can generate around 80% their peak energy even on cloudy days.
