Windfarms
The cost of construction of a windfarmis partially offset by tax
incentives. The cost of maintenance is high. Notice how many towers are out of
service at any time. The stress of the windshear as the prop passes the pylon
is a cause of blade fatigue.
Jed mentioned there is no better way to capture the wind with present-day,
off the shelf technology. True and the incentives exist to keep building them
although there is a better, more efficent, less expensive and lower maintenance
way using available technology. That should count for something.
The technology is available, albeit it in bits and pieces... to use
inclined updraft tubes for electric power generation. The base of the
tube could beconfigured similar to the shape of a chambered nautilus
and have an offset turbine shaft that fully captures the cross section of the
opening while achieving null on the backside of the rotation. to lower drag.
Seems more feasible than building a 3500 ft tall solar wind tower at 500 mil
plus.
