Tesla is building a secret battery in Texas. A VERY BIG battery!

Tesla is best known as an electric car company, but the firm also has a thriving business in battery storage—including utility-scale battery installations to support the electric grid. Bloomberg reports that Tesla is currently building a battery installation in Tesla CEO Elon Musk’s new home state of Texas. The project is in Angleton, about an hour south of Houston.

Tesla hasn’t publicized the project, which is operating under the name of an obscure Tesla subsidiary called Gambit Energy Storage LLC. When a Bloomberg photographer visited, a worker discouraged picture-taking and said the project was “secretive.” The project appears to consist of 20 large banks of batteries that have been covered by white sheets…

The installation will use lithium iron phosphate batteries that are expected to last 10 to 20 years. The document says that it will generate around $1 million in property tax revenue for the city of Angleton. The site will be unmanned but will be remotely monitored at all times, according to the document…

Cripes, you could produce a different documentary film, every week, on all the off-the-wall – but useful – projects Elon Musk is working on. Might do our boffins in Washington some good to take lessons.

Urban black bears are a fixture of life in the city, scouring neighborhoods for acorns, unattended bird feeders, and unsecured garbage, says Corey Arnold, a photographer and Nat Geo Explorer.
