CSP stands for Concentrated Solar Power, and it really isn't a cutting edge technology. It uses solar power, focused through mirrors, to heat water in a central tower (like in the image on the left), create steam, and spin a turbine to generate electricity. It's so simple and effective that it can currently deliver electricity at €0.15 to €0.23 a kilowatt.
