I don't think so - the energy would just be absorbed by "something" (walls, air, you name it - and turned into heat).

Not to mention that this isn't being sold as free energy, just another way of not having to keep changing batteries.

MrMobodies:
If they did manage to make it work could it also interfere with wifi operations like affect signal/thoughput and latency depending on how much charge it is draw from it?

tszaboo:
It is just virtue signaling. Rechargeable battery is only worth it, if you can charge it at least 10 times during it's lifetime, otherwise their environmental impact is larger than Alkaline batteries. With this, you need to place a rechargeable battery, a USB port, a solar panel, charge management IC, protection IC, and so on.
I was basically estimating for my product, that all these cost a lot more than a simple lithium primary battery, that would also give virtually infinite lifetime to the device. Just a high quality solar panel and an energy harvesting IC costs more than the battery.

Quite possibly. And bandwagon jumping. But without such efforts many things wouldn't get a start and lead to actual useful products years later.

Who said that there are batteries inside ?
It may as well be a supercap.
