In July, Spain’s Gemasolar concentrating solar power plant became the first solar project to generate electricity for 24 hours straight. The 19.9 MW Gemasolar plant features power tower technology with molten salt storage that allows a steam turbine to run for 20 hours each day on average. 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:

    There are lots of ways to harness solar power. Lots and lots of ways.

    There is solar silver buckshot everywhere.

    The news coverage seems to be about “24 hours per day”, yet this has been easily achievable for many years. This is not a record made by effort, but by accident. I suppose that any of the Andesol plants could have done the same just by cutting their power production down to the same level to conserve the hot salt for 24 hour operation.
