"Hidetsugu Yagi attempted 
<http://en.wikipedia.org/wiki/Wireless_energy_transfer>wireless 
energy transfer in February of 1926 with this antenna. Yagi and Uda 
published their first report on the wave projector directional 
antenna. Yagi managed to demonstrate a proof of concept, but the 
engineering problems proved to be more onerous than conventional systems."

   I think is a misunderstanding of what he actually did.  His 
papers include measurements of antenna patterns with current in the 
receiving antenna shown but this was not an attempt to transfer power 
in the same concept that Tesla proposed.  He was experimented 
with  numerous configurations of high gain antennas (called them 
"Wave Canals") and his designs are very popular unto this day.
