It is based on inventions of Nikola Tesla long ago.
When I worked at the science museum in Chicago, one part of the electricity demonstration was lighting an ordinary fluorescent tube wirelessly by high frequency induction. We did some tricks (probably originated by Tesla, although I didn't know at the time), like "wiping" the light on and off the tube. |
I have seen these appear around here over the last decade. Nearby strip mall replaced their sodium with them, there is two or three used at the university before the next annual budget went all-LED and a few of the MoT rest stops have them. Supposedly they operate on the same principle as fluorescent but with no electrodes they are overall better technology as they last longer, use less power and have a much larger striking range.
