Dutch scientists have successfully demonstrated a technology that could harness wind energy, by flying a 10-meter kite. Used in the U.S. mid-western wind corridor, the kites could possibly generate electricity more economically than windmills -- but unotrusively and silently. The kites capture the energy of faster-moving wind at 10 times the altitude of windmill blades. Scientists estimate that four times the energy could be produced.
Thanks to member Fred Gardner for calling this to our attention.
