In an effort to distract investors from its cash-burning car business, as well as to find some use for millions of Panasonic cells that it has committed to buy without being able to sell enough cars to utilize them, Tesla Motors (NASDAQ:TSLA) last week introduced a 10kWh home battery pack meant only for emergency back-up power.
It will cost $7140 installed, will be dead in fewer than five hours, and can't run an entire house or central air conditioning or charge an electric car.
Meanwhile, for the same price, a natural gas back-up generator can run all your appliances for as long as the power is out.
Thus, for anyone with access to natural gas, there's no rational reason to buy the Tesla back-up battery.
