1 mile per minute = 60 mph. 5 miles per minute = 300 mph. 5 miles per second = 300×60 = 18000 mph.

Isn’t 5mi/sec equal to 300 miles per hour?

Wow, “5 minutes of exposure to 5mi/sec winds will be able to generate enough juice…”

That’s like 3600 times as much wind as a mild 5mph wind! Since the power you get from wind goes up with the cube of the wind speed, this is 46 billion times as much energy as you might expect. You could run a city off this, if indeed you get that kind of wind and your device has enough area and doesn’t fall apart.

Anyway, it’s cool to have a non-plug-in car!
