What Elon told his top shareholders in Texas (Ad)

Late last year, Elon Musk gathered top shareholders at Tesla's Texas Gigafactory to unveil a plan to double America's energy output without building a single new power plant. The plan centers on a little-known Tesla-incubated venture already generating over 12 billion dollars a year and growing 168 percent annually. Musk says it could grow faster than Tesla's car business. A public reveal is expected on October 21, before wider attention catches on.tc pixel
