Another Step Toward Space Based Solar Power

 From Space.com: "Space-based solar power may be one step closer to reality, thanks to this key test (video)." From the lede:

    A first-of-its-kind lab demonstration shows how solar power transmission from space could work.  

    The demonstration, carried out by U.K.-based startup Space Solar, tested a special beaming device that can wirelessly transmit power 360 degrees around. That would be important for a potential future space-based power station, as its position toward the sun and Earth would change over the course of each day due to our planet's rotation.

    The demonstrator is a key component of the CASSIOPeiA space-based solar power plant concept that is being developed by Space Solar. The company envisions that CASSIOPeiA could be in space within a decade, providing gigawatts of clean energy much more efficiently than solar plants on Earth. 

Cool as this is, I would note that Tesla was demonstrating broadcast power 100 years ago.
