It's the same issue with everything.
It's the same issue with everything. It depends on scale. I wondered the same thing.
The problem is overpopulation. I disagree with Theotherwill below. "Small fraction" assumes that the project would be relatively small scale, but anything big enough to make a significant contribution to the power needs of a world overburdened by billions of humans might not be a "small fraction" of anything. There are other issues, too, as pointed out by the same poster below.
Our weather is ravaged by a sometimes fickle jet stream, so now we're going to depend on it for energy?
The biggest problem is the need for energy for so many people. If we could reduce population (hopefully through attrition!), then we wouldn't need "pie in the sky" ideas to generate energy!
