This is an interesting question and the outcome of mid-wind turbine technology is not a given.  We think energy density will drive design because these super energy-rich mid-wind sites are small in area (e.g. the San Gorgonio Pass in Southern California).  H-types can be placed less than 3´ from each other and produce beneficial vortices. The company that comes to the market first with the best patents will win a large share.  Maybe new technology will produce even better vortices and draw more fast-moving wind towards the ground but we think our patents and turbines which will last 40-50+ years will always have a good share of the world’s massive market of untapped mid-wind resources.
