eevBLAB #64 - Tesla Solar City Panels Are CATCHING ON FIRE!
Not as much detail as the Meet Kevin synopsis, but he wonders what Walmart must be thinking about their order for 45 Tesla semis.
I have room for a 3x24-32ft solar collector. I was thinking about a hot air system (plus the roof insulation it would provide). Might it be possible to duct air across the backside of the PV panels for space heating?
