There’s a scrolling banner on the Brilliant Light Power website which is announcing an upcoming demonstration of their SunCell technology.

The text is:
“We are planning an invitational public demonstration of the SunCell in the January 25-Februay 5, 2021 Time Frame. It will be video streamed by popular demand”
It appears that the exact date has not been chosen yet, but it will be somewhere in that timeframe. Hopefully the video stream will be made public, not just available to invitees
