> " ... deriving energy from the Earths magnetic fields, from solar radiation, & from industrial & environmental electromagnetic noise." If when you roll it over there is a PV panel on the other side it may almost make sense. Almost. A 1 Watt panel would charge in 14 days at 1 SSH (sunshine hour =3D hours of equivalent sun per day) and a 500 mW panel in 2 SSH/day. You might maybe sort of fit a 500 mW panel on there. Energy harvesting form local radio sources would need to be at 35 mW average continuous to meet the claim if storage was 12 Wh. IF the LED was 3W as claimed then you'd need 36 Wh which would not start to fit. It's a scam. Exactly what sort is TBD.
