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
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?
