Companies showed off their latest clean energy innovations at the ARPA-E Summit.
1. This is a model of a generator being developed by the Georgia Institute of Technology that looks to take advantage of natural air movements in hot areas. When the sun's heat hits the ground, a layer of hot air forms at ground level. If that ground-level air is hotter than the air above, it can create upwardly moving whirlwind. In nature, this columnar vortex phenomenon creates "dust devils," or spinning whirlwinds that lift dirt off the ground. In the device, hot air rises through the turbine, generating electricity.
