Solar powered devices are used in many things these days and of course the military is going to take part in this as well. This robotic BAT spy plane is designed to gather up real time data to provide to soldiers and the Army has given a 5 year 10 million dollar grant to the University of Michigan College of Engineering to create it. This is a very cool concept and will us quantum dot solar cells which are twice as effective as photovoltaic solar cells. via IH
