eh.... self charging?
regenerative braking isn't exactly new.
capacitors aren't exactly new.

You could do the exact same thing with a lithium batter bike (car/plane)

Everything in this video is exaggerated.
Most of the energy expended while cycling is wind resistance. Energy lost to braking is minimal in comparison.

The only interesting part is the capacitors.
Even so, I see no technical breakthrough on energy density.

Granted, as soon as true "super" capacitors are developed and released publicly, all fossil fuel technologies and chemical battery technologies become obsolete over night.

I look forward to that day.
