Battery substitute for plug power supply?

Hi guys!
I want to make a cheap and nifty laptop (sort of) using Raspberry Pi. I've managed to scavenge a small monitor, a mouse and a keyboard. I wanted to know if there is some way of using a battery pack of some kind to power the machine so I can use it as a laptop. Is the power supply small, if so can I use normal batteries? And if not, what else can I do? Solar power? Anyway, thanks.

The Mag Pijust had an article on solar powering your Pi. It's in Issue 7.
There are 10 types of people in this world. Those that understand binary, and those that don't.

Remember the Raspberry Pi runs on 5 volts. Four regular batteries would be six volts. But rechargeable batteries are slightly lower voltage. So I would recommend something like four AA rechargeable batteries. You will likely only get an hour maybe two of use though.

you got to think of what voltage the screen runs on i myself use a pack of 18650's from old laptops they are in parralel so the voltage stays the same but the amp hour grows i thin use a dctodc buck inveter to take the 3.7 upto 5 volts
