For the survival-inclined, from the Harvard Press:
“Around the corner at Madigan Lane, John Sweeney, a member of the town’s conservation-minded Heat Advisory Committee, took a characteristically green approach to powering his home during the [ice] storm. He reported his achievement in an e-mail, saying it was no big deal, but that his wife thought it an impressive tale worth sharing: Sweeney ran his refrigerator, freezer, TV, woodstove fan, and several lights through his Prius, for three days, on roughly five gallons of gas.Nice, huh? From what I can tell, there are several kinds of power inverters. Best check with someone knowledgeable--for instance, an RV outfitter accustomed to recommending power inverters to run appliances from a vehicle battery--to see what kind will work best for your needs. [Note: I'm not specifically endorsing the roadtrip america site. I list it here only as one of many possible sources for background information only. Use it or any other information source at your own risk.]
“’When it looked like we were going to be without power for awhile, I dug out an inverter (which takes 12v DC and creates 120v AC from it) and wired it into our Prius…These inverters are available for about $100 many places online,’” he wrote.
“The device allowed the engine to run every half hour, automatically charging the car battery and indirectly supplying the required power.”
