On a roadtrip earlier this summer, we drove past the Ivanpah Solar Power Facility outside of Las Vegas, Nevada. Each of the three 460 ft towers has roughly 115,000 mirrors directing sunlight at them. I had heard something about this when it was being built, but I did not imagine what it would look like. You can see it for miles around; they are so bright.

Another view:
You can see the mirrors a bit in this picture:
This satellite view on Google Maps shows the mirror array.
They are shutting down the facility next year unfortunately. Hopefully it’s replaced with another renewable energy source. I’m glad I got the chance to see it though.
