Thread: Spherical crystal globes enhance solar energy, light interior spaces, and add architectural beauty

When I first saw this I thought it was woo-woo "crystal magic" or some such, but it's actually legitimate concentration of light energy that both enhances solar generation, and can provide an architectural light source. It's also rather beautiful in and of itself and would make a worthy addition to any modern architectural endeavor.

They claim it can even concentrate the energy enough to get solar energy from Moonlight, although I doubt it's much.

I looks like a great big Campbell–Stokes recorder.

Works off the same principles, it looks like, but with a movable target.
