Do you have a Generator? I'm buying one for my house in case of a power outage.
Just remember to test it every year. I bought a portable generator in 1992. In September 1998 it saved us during a 7 day outage due to a severe local windstorm. I let it sit until last year when the remnants of Hurricane Irene were approaching Northern NY. It took me a couple of hours of tweaking to get it running right the day before the storm hit.
An interesting note: I screwed up the speed governor trying to get it running, so that it was producing power at too high a frequency. I had MIT grad student working on his PhD. in Electrical and Computer Engineering visiting that weekend. I challenged him to figure out a way to synchronize the frequency of the generator to that of the commercial power (that was still on). While I worked on something else, he developed a plan to use the microphone on his laptop to input to a Fast Fourier Transform program to analyze the frequency of the exhaust tone from the engine. He couldn't quite make it work. Then I took a little electricians neon test light and connected it between the hot legs of the generator and the house power, and adjusted the generator speed until it stopped flashing. (The light flashes at the rate of the frequency difference). Old tech beats new tech!
