I guess you wouldn’t want a hail storm with this installed.
how effective are solar vacuum tubes in cloudy weather i.e. in defused sunlight
stuck on stupid? have no fear some deranged stress monkey wants to play with you on your time with this.
How much does this cost? Where do you get it?
I wonder how helpful this would be for people in arctic tundra conditions.
