No such thing as free energy, yet.
Nobody said anything about free energy. ‘Free’ in terms of there are free electrons that form the beam, not light photons..............
Wait 'til the State of the Union speech. I think Obama promised to cure cancer in his first SOTU, so he may promise free energy in the upcoming one.
"Why sir, how can you doubt me? As sure as the sun rises.... it's FREE! In fact, dear sir, DOES ANYONE CHARGE YOU MONEY FOR THE SUN? NO! NO, I say! The sunlight you have on your dapper suit, RIGHT NOW, is FREE! That, sir, is free energy and may God strike me dead right now if I lie."
