Elizabeth's point is important. Apart from efficiency considerations, a big objection to HAWTs is their harm to birds and bats. It seems to me that VAWTs could be more easily shielded or caged so that birds cannot enter the blade path. There has to be a better way to catch wind energy than those view-spoiling propellers. Environmental concerns should be weighted vis a vis effeciency.

Actually, William, there are two truisms in this article.  The other is "overzealous marketing outweighs good engineering."  How many times have we had to tell marketing "NO!" 

I was very happy to read this report about relative efficiencies of the vertical and horizontal systems.  I have been quite interested in pursuing the energy field for survival usage, and the vertical systems solve a lot of problems- portability, footprint, etc.  Now I need to find out who has developed the best system for portable use.

Warren, It is certainly true that the logistics of setting up a vertical turbine are a bit less daunting. So if something besides cost is considered they are probably a better choice. It does seem that with only vertical rotating components and no wind-tracking hardware that the mechanism is far better suited for survival situations. And thos wires snagging birds could be a useful source of food. Unintended consequences, you see.
