Tesla Invented A Wall That Lets Households Run Entirely On Solar Energy

The innovative electric car company Tesla is expanding its scope beyond just cars. It wants to power the world.

Today, CEO and founder Elon Musk unveiled the "Powerwall," a wall-mounted, rechargeable lithium-ion battery that can power a household without using the grid, reported TechCrunch.

The Powerwall is a part of Tesla's new branch called "Tesla Energy," which is focused on ending our dependence on grid power and switching instead to solar energy.

"The issue with existing batteries is that they suck," Musk said during the press conference. "They are expensive, unreliable and bad in every way."

And, as always, he has a solution.

Powerpacks cost $3,500 for 10kWh and $3,000 for 7kWh varieties. They are open for pre-order in the U.S. now, and the first orders will be dispatched by summer.

He estimated that 160 million packs could shift the U.S. to renewables while 900 million units would be enough for the entire world.

Musk, known (among other things) for his no-patent policy, allowing his biggest rivals to use the technology he developed in order to hasten the shift toward electric cars, wants others to build on his work in order to find the best solutions. He is clearly changing the world — and doesn't want to do it alone.
