I was at the talk, and it wasn't very informative. Sadly, half way through the talk a free-energy wacko believing in a Hitler from the future hijacked the discussion, causing half of the people to leave. The speaker did not address the transmission efficiency and got heavy criticism of a physics professor contradicting his explanation for the power transmission. Nevertheless it's worth watching this talk for his sophisticated simulations of Tesla coils showing the electric and magnetic fields generated by them.
