Solar Powered Laser
One way of creating renewable energy is to use magnesium. Some scientists call it the magnesium combustion engine. Magnesium is very abundant and is able to hold a lot of energy. One of the problems is the intense heat needed to make it work and that is where the laser comes in. Here is a link to more details about this solar powered laser: http://www.technologyreview.com/energy/19402/
