Phil Berardelli (ScienceNOW Daily News) has published a neat story here on the benefits of a specific configuration of vertical-axis wind turbines (VAWTs; example here).
VAWTS, arranged in a pattern that mimics schooling fish, can provide a similar energy output to traditional, horizontal axis wind turbines (HAWTs) on approximately 1/100th of the land area. Thus, VAWTs, already a preferred design for conservationists because they appear to present a far lesser threat for bird collisions, could also provide a substantial benefit in terms of land use conversion. That is, of course, unless greedy developers simply take this information to mean that they can reap 100X the power output from the same enormous land area they want to develop . . .
