So you're looking for a impact wrench, and you need something that's portable. Electric impact wrenches (most notably cordless ones) are no longer under-powered and over-weight, and there are plenty of reasons why they are better than their air powered cousins.
And do not freeze the battery, this can be just as destructive. If you think you may want to buy a spare Li-ion battery to have on hand as a back up, don't bother. They have a shelf life so if you do not use it before it ends you have wasted your money. Also check the manufacturing date on a battery you may be buying to be sure the lithium stocks copyright expiration is not approaching.
These bikes do have batteries, NiMH or lithium ion batterty stocks ion, which have to be charged. The average bike will run for at least three hours on a full charge.

By changing to a hybrid vehicle, it will help erase some of your gasoline bill while helping the environment. If you spend $300 to $400 a month (or more) on fuel, multiply $400 a month times 12 months, that's $4800 a year on fuel. It would take several years to pay off the Volt. By that time, the car may be shot. You won't erase your entire gasoline bill - because you use both battery and gasoline - but it will help reduce it. I think purchasing a hybrid is a good thing but it's too long for a payback. I know the technology is available but the ROI, return on investment, is not there. If you spend $40,000 to $50,000 you may not be able to get that back within 5 years or longer.
