they're cool, but have weird problems, the one in mojave, had issues with literally vaporizing birds, which might be worse than traditional wind turbines. Considering you can see them.

The mirrors are incredibly susceptible to dust and debris, being in a desert doesn't help all that much, so they have to be regularly cleaned. The actual mechanism of heat conversion works, but you can just do the same thing with electric resistive heat and solar, or wind, as heat storage so meh. Though it probably doesn't work quite as well.

I have high hopes for EVs being used as a decentralized buffer via V2G. I'm thinking of something like you either buy an EV outright and you have no obligations to participate in V2G, but can sell electricity that way if you wish. Or, the government subsidizes your car to a certain extent but you have to give maybe 20% of your battery up as a buffer as long as it's connected to the grid.
