He built some real world devices where he can transmit energy wirelessly with what he calls, scalar energy. Interesting guy, has a few talks in german, pretty interesting, sadly had a stroke recently.

I have heard a little about scalar, but need to learn more. These things have been discovered by many and I am confident that the basis for all of these things is working off of the same principles, with very specific geometric field arrays.
They all tried to patent and/or monetize it and it never ends well. This needs to be open sourced and published widely.
