What do you think? Completely Impossible?
To quote the 1st of Arthur C. Clarke’s three laws of prediction
“If an elderly but distinguished scientist says that something is possible, he is almost certainly right; but if he says that it is impossible, he is very probably wrong”
Is this the 1st stage of Clarke’s Law of Revolutionary Ideas, or just Science Fiction? If it is for real, this would indeed be a revolution in antenna design. If not, it's still an intriguing thought, and on that alone the video is worth a look.
In an article from Technology review back in 2009, a process for creating nano-capacitors developed by Sang Bok Lee, and Gary Rubloff was described. The process was similar to the ones used to make memory chips, orders of magnitude more difficult than the "spray on" method described in the Solve for X video.
