...AND CHEAPER...:

Tesla Motors may be close to eliminating the electric bill, at least for some consumers.

Company CEO Elon Musk is expected on Thursday to unveil batteries capable of powering a home or a business, giving consumers with solar panels a chance to generate and store their own energy, and to potentially cut the cord with traditional power providers.

Musk - also chairman of clean energy company SolarCity - revealed his plans in a recent earnings call, letting slip that his company will "unveil the Tesla home battery ... that will be for use in people's houses or businesses, fairly soon."
