Any information on this one? It looks like the coffee can is full of a hardened material. A 13 year old playing a joke?
It says is uses "radio waves, thermal, and static energy". Probably never hear about this one again.
I don't think it's a joke. They say it runs on radio waves. Probably not unlike holding a fluorescent light under power lines that lights up in your hands.
Just in case, I have contacted Exxon headquarters and expect the boy to have an unfortunate accident within the hour. The system works.
