There you go - scale it down by volume and you get a 2" cube providing 1kW for.. um.. a lot longer than 5 minutes anyways, the energy density is orders of magnitude apart. This technology might a be a little ways down the road for model use though..

I hope they can make it work but I don't think this will be a viable RC power source even in 20 years.

Well, maybe 50 years, who knows. In any case I won't be around to enjoy it! But man carrying electric aircraft.. hmm..

You can buy man carrying electric aircraft today.

And there are some exciting developments in electric and solar for the near future
