Popular Mechanics calls this a "generator," though it is a very advanced rechargeable battery pack, and does not generate electricity, itself. That, though, does not alter the fact that a home with a solar roof could charge this pack quite efficiently, especially in the US sun belt, or in countries that enjoy exposure to sunlight for much of the year. The initial price of this pack is high. But then, once you buy it, if your home does have a solar roof, you will not have to spend any money for the life of the pack. Ditto for states like Texas that have highly efficient wind power systems, and where utilities offer free electricity at night. Plug it in when you have free electricity, and use it when the billing cycle starts . . .
