Subject: [alt-beam] Re: BEAM Prism ??
I'll have to get working on one, but now that I think of it,
the angle between the sun and the wall spot would not remain
constant. The sun moves but the wall doesn't, so I will have to
have a mirror, also rotating, to reflect the beam exiting the
prism toward a constant spot on the wall angle of the prism to
track the sun. Might be tricky, geometry-wise that is....
