Last week, a heavy hitting consortium of companies unveiled plans for a $550 billion solar farm to be built in the sunblasted North African desert. The plan called for the biggest ever deployment of Concentrated Solar Power (CSP), a massive effort that could supply 15 percent of Europe's power. CSP entails using mirrors to redirect the sun's rays to heat up water or oil with a concentrated heat beam. Ideally, this will also power large-scale desalination plants to green North Africa and stimulate agriculture. I spoke to Travis Bradford, a noted expert on solar energy and the executive director of the Prometheus Institute, about the project.
