Of course, that's 3 cents to store and deliver a kilowatt hour. That's on
top of production costs.

"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.
Re-read that last paragraph and let the information really sink
in. Five kilowatts over four hours -- how much is that? Imagine
your trash compactor, food processor, vacuum cleaner, stereo,
sewing machine, one surface unit of an electric range and
thirty-three 60-watt light bulbs all running nonstop for four hours
each day before the house battery runs out. That's a pretty
exciting place to live."
