Acouple of miscellaneous questions.

3-6 hours, depending on what I'm doing on it.

Yes. Poorly.

And I would use Nuclear.

How many hours do you get out of your laptop's battery?[/quote}
I get maybe an hour, but that's a short life.

Can gas-powered electrical generators be used indoors? If so, how do you deal with the exhaust?

Yes.
What exhaust?

My buddy doesn't want his character to die from asphyxia in his Dimensional Room, since that would suck. However, one needs electricity in there, yes?

Thanx.

What do you need electricity for?
As for oxygen, get a couple of plants.

Never recommended to use anything that causes fumes in any enclosed space, especially this one (presumably Dimensional Envelope), that has only a couple hours of air for humanoids (and 24 hours' worth of air for Dragons). Otherwise, you'll have have to roll on the Asphyxiation Table......
