Coiled up in a tornado is as much energy as an entire power plant. So a Canadian engineer has a plan to spin up his own twister and extract energy from its tethered tail. http://www.msnbc.msn.com/id/25374237/ The real interesting part of this possible new way of generating energy is where to get the warm air supply from. Waste heat Michaud imagines the AVE could get its warm air from the exhaust of a power plant. "Most power plants reject more than half of the heat that they make," he said. Shame the guy has not received any funding to date to work out the kinks of the system as all funding has come from his own pocket. Oil prices keep going higher we will continue to rapidly advance technology for alternative sources.
