Re: That's the future
OK lets take wind as an example - they've become more efficient? NO they are still inefficient just that they're bigger and there are lots more of them.
Actually, they have become significantly more efficient as they have become bigger. Smaller ones only manage to extract about 30% of incoming kinetic energy while the biggies can get 45%. Which is not bad, considering that the absolute limit (the Betz limit) is 59%.
