Scientists at Washington State University have invented a way to harvest energy from solar wind. They estimate this device could gather 1 billion gigowatts of electricity. Their ambition is to soon power the entire world with one these solar sails, although their main problem so far is figuring out how to safely transport this energy back to Earth. The scientists also claim that making these solar sails would be cheaper than putting solar panels in space because these sails are made of copper, not photovoltaic cells. If these sails become useable, they would be extremely energy efficient, no doubt.
