kazoo_indoor_kite

What we have here is an indoor kite. I know it sounds crazy, but it is remote controlled… and has an electric motor in it. Some people would say that makes this a remote controlled… UFO or dirigible or something. I would be one of those people. I would also try to trick the local news into running yet another news story about UFOs over Phoenix [google].

This thing costs about $15, and probably performs as well as you’d expect a remote controlled anything to perform.

It’s called the Kazoo… an appropriately off-the-mark name for such a toy, and you can pick it up at Hobbytron, where they have tons of inexpensive remote controlled flying toys.

A recent breakthrough in aerodynamic efficiency was inspired by ocean life. It all started when one man noticed that the leading edges of the fins on a model whale were ridged. He assumed that it was a sculpting mistake, but after studying several species of undersea life, he noticed a trend.

Since the dawn of flight, man has assumed that a smooth leading edge is the best approach to flight. As it turns out, adding bumpy edges to the front of a wing makes the air travel in channels over the wing, resulting in a more efficient and stable flight.

This new revolution in aerodynamic technology is leading to the reinvention of many existing technologies, including fans, compressors, wind turbines, pumps and so much more.
