That You tube video makes no sense at all. It looks like a copper cable wrapped around a burned donut.
So how is it supposed to work?
How much energy do you expect to realistically get from it and for how long in terms of practical Kw hours or watt hours?
And what will it cost to build and operate?
No offense but if this thing doesn't drive half way across the continent on one charge its just a fools toy and a giant waste of money that could be spent far more wisely. And I can guarantee that someday it will be greatly regretted for having been spent so foolishly.
I suspect in real life operation if it works at all it will probably get its butt handed to it in a endurance race between you and the 5 year old neighbor girl with her Fisher Price Barbie jeep!
