hydrogen is time away, it's not even up and running for full scale autos yet.
LiFe is the next thing power wise, that will replace LiPo as it's more stable and user friendly, beyond that power cells seem to be the next logical step.
and i would'nt be surprised to see super conductor tech work its may into esc's keeping them super cool and efficient over the next few years.
on a more voyeuristic note, surely there will be a way in the near future to combine, VRC, Transponders and GPS tech so you could watch the race unfold on your pc in real time? The live stream is great, but useually seems to focus on one car or one section of track.
imagine being able to download an entire a-final and then follow which ever driver you want, even in car, sweet.
