In July, Spain’s Gemasolar concentrating solar power plant became the first solar project to generate electricity for 24 hours straight.

The plant will generate about 110 gigawatt-hours of electricity per year — almost triple what an equivalent solar photovoltaic plant would produce.
CNN had a good piece this weekend looking at how the plant works. It’s worth a watch:
