In reply to James Bowery's message of Mon, 19 Aug 2013 17:17:25 -0500: Hi, [snip] Despite what I wrote below, there may still be a future for this technology, if combined with conventional wind turbines. On windy days the vortex may not work, but the wind turbines would do well, and on wind still days it would be the other way around, so the two complement one another.
>You obviously haven't done, even to a first order of approximation, the >power flow estimates. True, but that's not going to stop the wind from blowing the vortex sideways off it's base. Regards, Robin van Spaandonk http://rvanspaa.freehostia.com/project.html
