Gregory's Server@neauoire That's so cool! 🤩 Which curve is the reflector? Parabolic? Or is it the elusive compound parabolic concentrator?

@neauoire Ooh🤔 that sounds like an involute curve, the first curve segment of a compound parabolic concentrator. @neauoire One word of caution 🚧 : I've heard of tubes freezing and breaking if they're exposed to clear night sky -- but this event occurred with vacuum tubes with interior metal tubes filled with water. The research group at UC Merced had to cover their vacuum tube + reflector experiment at night due to hazardous radiative cooling.  @clh3 ours are different, we use the household type that is normally installed on rooftops. |
@clh3 it's a piece of bent stainless that curves to follow the shape of the tube. I'm not sure what its name is
