"Under the most recent design specifications, the first San Luis Tower has a design capacity on an hourly basis, of up to 1250 megawatt hours, gross. Using a 60% capacity factor, the Tower’s potential hourly yield would be 600 megawatt hours from which approximately 18.5% will be used to power its operations, yielding approximately 500 megawatt hours available for sale to the power grid. Due to lower capacities during winter days, the average daily output for sale to the grid for the entire year is approximately 435 megawatt hours." http://www.cleanwindenergytower.com/the-tower.html
This is a bit of a mess, possibly from some confusion between megawatts (power) and megawatt-hours (energy). Is the gross capacity 1250 MW, or 600 MW, or what?
An average daily output of 435 MW-h would be an average power of 435 MW-h / 24 h = 18 MW. Which is absurdly small.
'... about 750 permanent employees will be needed to maintain the tower and its 25 “generating plants.”'
That seems like an unreasonably large number. Conventional wind farms' employees number in the dozens.
In the linked interview with the CEO http://thestockradio.com/ceo-ron-pickett-of-clean-wind-energy-tower-inc/1766
~2:20: 'Turbines *in series* capture 90% of the energy of the air', would seem to leave a lot of air piling up around the base of the tower.
~3:30: 'An all-in cost for the average wind farm of 18.5¢/kW-h' is a considerable overestimate.
