Micro Hydropower : Turbulent Turbines

Hydropower has been with us for millennia, but the 20th Century race to build huge centralised hydropower dams in many parts of the world has caused untold environmental damage. Now a new micro-hydropower technology is working with the natural flow of water and wildlife rather than against it, to bring much needed constant baseload power to off grid areas in remote areas of developing nations.

The Tesla Mafia: How Elon Musk’s Ex-Employees Are Becoming His Top Rivals | Forbes

PayPal is famous not just for its pioneering of electronic payments but also for its mafia—a group of successful alums who went on to start or fund companies ranging from Yelp and LinkedIn to Palantir and Affirm. Now Elon Musk, the gang’s most famous capo with his vast Tesla wealth, has spawned a newer mob that might one day rival the original. A string of former employees at the carmaker have gone on to form electric vehicle and battery companies, mostly in California. (Dozens of others have landed at EV companies like busmaker Proterra and truckmaker Rivian.) These ex-Tesla staffers are poised to have an outsize impact on the $6 trillion global auto industry in the decades to come.
