What is it: Bloom Energy creates fuel cells called Bloom Boxes that produces clean energy and the first customers for these devices included Walmart, Federal Express and Coca Cola according to The Guardian. The cost of these boxes are $750,000 but Sridhar hopes to cut that down $3,000 within a decade. That may be sooner rather than later. In order to cut down on greenhouse gas emissions, Fast Company writes that eBay purchased five boxes and saved $100,000 in under a year.
