The author feels there two broad technical and commercial reasons why VAWT has struggled. One is technical: VAWTs are low to the ground and don't capture the high winds like the 60-80m hub heights of HAWTs. Reason two is commercial: the same old story of technical innovators whose marketing story hasn't been well-banked, well-communicated, nor well-timed....
