| | Boing Boing: Tornado power |
 | | Sean Ness, my co-worker at the Institute For The Future, is geared-up about a Canadian engineer's invention that spins synthetic tornadoes and harnesses their energy. |
 | | This vortex would be produced inside a large cylindrical wall, 200 metres in diameter and 100 metres tall. |
 | | This is, in fact, what powers a hurricane, which can be thought of as a heat engine that takes in warm, humid air at its base, releases cold, watery air at the top of the troposphere, about 12 kilometres up, and liberates a vast amount of energy in the process. |
