Energy

Solar energy will soon leave fossil fuels and inefficient wind farms in the dust. According to Kurzweil, “the cost per watt of solar energy is coming down rapidly and the total amount of solar energy is growing exponentially. It has in fact been doubling every two years for the past  20 years and is now only eight doublings away from meeting all of the world’s energy needs.”

Emerging technology from a company called Sandia is making the reality that much closer:



Sandia’s solar cells are made of 100 times less material than the current top solar cells while operating at the same efficiency. Since the biggest hurdle in the path of solar power is the expensive and large nature of solar panels, these new microscopic cells will make a huge difference. For example, current panels are massive and require large motors to move them to track the sun. Sandia’s cells, on the other hand, would only need to be moved a fraction of a millimeter to track the sun efficiently while weighing next to nothing.

Even more amazing, they can be suspended in liquids and printed on flexible materials, allowing the cells to be places on any surface. What if your entire car was covered in these powerhouses? Bye bye, Chevron.
