Subject: Non-Radiative Evanescent Waves are back in the news...
By using a weakly coupled resonant receiving coil 1/2 meter in diameter,
the research team that rediscovered induction and Tesla wireless power
transmission last year have successfully lit a 60 watt bulb 2 meters
away from a transmitting coil. I wonder if the lamp was continuously
illuminated or a flash (when the lamp was connected across the fully
"rung up" receiving LC circuit). The researches claim 40% efficiency.
Will be interesting to get the complete story instead of this snippet:
