00:00A single mature typhoon releases heat at a rate of about 600 terawatts
00:06as water vapor condenses into rain.
00:08That's roughly 200 times the world's electricity-generating capacity.
00:14But you can't simply harvest it.
00:16Almost all of that heat drives rising air, convection, and rainfall.
00:21The estimated kinetic energy generation that maintains the storm's winds
00:26is about 400 times smaller, around 1.5 terawatts.
00:31Still insane.
00:33Over its lifetime, a major storm can release an amount of energy
00:37comparable to thousands of nuclear bombs.
00:40And Japanese engineer Atsushi Shimizu developed a vertical-axis magnus turbine
00:45designed to keep generating electricity in extreme winds
00:49instead of relying on conventional propeller blades.
00:52And typhoons aren't unstoppable.
00:54Over land, cooler water, or under unfavorable atmospheric conditions,
00:59they can weaken rapidly.
01:01A typhoon is essentially Earth's enormous heat engine,
01:05and most of its energy is simply too diffuse and powerful to plug into.
