I kid you not.
Back in my teaching days.. Yes, I used to teach Computer Science in College and Graduate School... Not the sexiest job for a man based on surveys I know, but it was my first serious job so.. there was this lecture I gave on technological innovations and we were talking about Bluetooth (it was new back then.. makes me feel real old thinking about it) and I jokingly said that someday there would be wireless electricity as well. I remember the class laughing when they imagined themselves walking over a wireless electrical connection and electrocuting themselves. That was less than a decade ago. Now lo and behold, it's actually here.
It's called WiTricity, a research that had its beginnings in MIT back in 2006. Led by Professor Marin Soljačić, a team of physicists started working on the model and came up with what they call a Source Resonator, which when paired to a another coil (receiving device), will deliver electricity to an appliance. Wirelessly. The secret? Magnetic field.
