Hmm, 30 seconds? And the charging current?

Do a search, we had that topic before.

On the other paw, fuel cells are nearing production ready state and miniature internal combustion engines are already in development too.

Yes, imagine a car engine shrinked down, so that it fits into a mobile phone, driving a little generator.

And maybe we see miniature gas turbines as well...

No, I'm not kidding you, check out the usual publications (Technology Review / PopularScience etc...) and you find a

bunch of information about these.

A few years down the road, you will fill up your laptop at the next gas station...
