It's easy to make up "requirements".   Most of them are BS.   If somebody 
came to me with requirements like those above, I'd say: wow, aren't you 
special.

I could come to the US electric power grid and ask it for femtosecond 
pulses of energy on demand at any random time I choose, with the only 
constraint being that I never use more than 1 Megawatt-hour per year, 
averaged over a year, which is really a modest power consumption.

Sounds reasonable, right?   Any power network should be able to do that if 
I just connect my load across the 110V terminals, and switch it on?
