The James Webb mirror is a rigid, astonishingly precise focusing element. A solar energy mirror could instead be merely approximately parabolic, made of a foil instead of cryogenic, made of metalized kapton instead of gold-plated beryllium, would forego focusing elements, and so on. However, the thought of a telescope-quality mirror 250x the size of the JWST is pretty amazing :) |
