Running on Batteries

Neat stuff!

...a team of specialists in advanced materials and electrochemistry has produced what could be the single most important breakthrough for clean, alternative energy since Socrates first noted solar heating 2,400 years ago.

The prize is the culmination of 10 years of research and testing -- a new generation of deep-storage battery that's small enough, and safe enough, to sit in your basement and power your home.

...Ceramatec says its new generation of battery would deliver a continuous flow of 5 kilowatts of electricity over four hours, with 3,650 daily discharge/recharge cycles over 10 years. With the batteries expected to sell in the neighborhood of $2,000, that translates to less than 3 cents per kilowatt hour over the battery's life. Conventional power from the grid typically costs in the neighborhood of 8 cents per kilowatt hour.

...A small three-bedroom home in Provo might average, say, 18 kWh of electric consumption per day in the summer -- that's 1,000 watts for 18 hours. A much larger home, say five bedrooms in the Grandview area, might average 80 kWh, according to Provo Power.;Either way, a supplement of 20 to 40 kWh per day is substantial.

The other large plus for this system is that it will not require a "do-over" of the entire electrical grid. It will be a supplement.
