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.

More often than not, with the purchase of a sports car comes the sacrifice of any sort of utility. In other words, you can forget about a large trunk, extra seats for the kids, and more importantly driving in snowy (or inclement) weather. But what if there was a vehicle that offered the best of both worlds; great handling and practicality?
As additive manufacturing (including 3D printing) becomes increasingly popular among businesses as a quick and easy solution to creating and evaluating prototypes and end-use products, the debate about whether to outsource production or to purchase equipment for in-house use is at the forefront of industry discussions.
With increasing terrorist threats overseas, organizations are thinking about how best to defend themselves here and abroad. Engineering can play a role, especially when it comes to putting a barrier between yourself and the bad guys.
Time to market is everything, but at the same time, you cant sacrifice quality for speed. Thats where additive manufacturing comes into play.
In the last few years, use of CFD in building design has increased manifolds. Computational fluid dynamics is effective in analyzing the flow and thermal properties of air within spaces. It can be used in buildings to find the best measures for comfortable temperature at low energy use.
