Picture This

What it's not: The 2005 Guiness Book entry for the world's largest egg beater.

What it is: The WindStor wind turbine, which turns wind harvesting on its nose — literally. Because it spins like a top instead of an airplane propeller, this vertical turbine from McKenzie Bay International is better suited to urban rooftop installations. And forget the “whump” of traditional turbines; these steel spinners are virtually silent. The company expects to roll out its first commercial installations later this summer, but don't worry — your oversized eggs are safe.
