Unscramble the Blue Letters


So this is the equivalent for a kite flier of peeing in the snow — that's tracing your name in the sky.

And this is where we're actually going. So we're beyond the 12-second steps. And we're wokirng towards megawatt-scale machines that fly at 2000 feet and generate tons of claen electricity.

So you ask, how big are those machines? Well, this paper plane would be maybe a — oop! That would be enough to poewr your cell phone. Your Cessna would be 230 killowatts. If you'd loan me your Gulfstream, I'll rip its wigns off and generate you a megawatt. If you give me a 747, I'll make six megawatts, which is more than the largest wind turbines today. And the sucpre gsooe would be a 15-megawatt wing.

Original Text


So this is the equivalent for a kite flier of peeing in the snow — that's tracing your name in the sky.

And this is where we're actually going. So we're beyond the 12-second steps. And we're working towards megawatt-scale machines that fly at 2000 feet and generate tons of clean electricity.

So you ask, how big are those machines? Well, this paper plane would be maybe a — oop! That would be enough to power your cell phone. Your Cessna would be 230 killowatts. If you'd loan me your Gulfstream, I'll rip its wings off and generate you a megawatt. If you give me a 747, I'll make six megawatts, which is more than the largest wind turbines today. And the Spruce Goose would be a 15-megawatt wing.
