Many inventors have questioned the logic of harnessing wind power by situating heavy gearboxes, generators, and rotor blades hundreds of feet in the air, as is the case for conventional horizontal wind turbines. One alternative design that does away with all these entities looks as though it is getting traction from both investors and a few potential customers.
When it comes to the future of wind power, one company thinks it looks a lot different than you would expect, and cheaper and more efficient to boot. Saphon, out of Tunisia, is interested in finding partners to mass-produce and market their unique wind energy device, based on their own Zero Blade technology.

ROCKET LAUNCH PRODUCES NOCTILUCENT CLOUDS: On Tuesday morning, August 5th, a SpaceX Falcon 9 rocket lifted off from Cape Canaveral carrying the AsiaSat 8 telecommunications satellite. About an hour and a half after the 4 AM launch, electric-blue clouds appeared over Orlando FL:
"These clouds appeared just before sunrise," says photographer Mike Bartils.
These are, essentially, man-made noctilucent clouds (NLCs). Water vapor in the exhaust of the rocket crystallized in the high atmosphere, creating an icy cloud that turned blue when it was hit by the rays of the morning sun. Years ago, space shuttle launches produced similar displays.
