I've got to visit something similar at Sandia National Labs. https://energy.sandia.gov/energy/renewable-energy/solar-ener...

(The video at about 6 minutes shows cool footage of spaceship material being tested)

I got to see it just as a tour, I don't work in that field and don't know how it compares to the Odeillo solar furnace.

There's a group of three such power stations near Las Vegas. I passed them on the way from LA a few months ago.

I don't know if they permit visitors. There's something odd about the way the light makes the air glow near them. From a distance, they look unearthly; almost CGI'd.

I wish I had, I just finished up a month working in the area (Osseja) this summer, always wondering what that big shiny thing was on the hill across the valley. Turns out I was 18km away from this really cool structure, what a small world feeling figuring out what it was here.
