If that is a continuous feed then the base of the tether would need a barge to permanently store the Helium canisters. The barge and its cargo would be vulnerable to rough seas. And resupply missions would need to take place regularly. If the Wind Ladder is a mile-high version and has 20 inflatable units, then a larger feed would be needed, maybe 40 cubic feet per minute, if your original estimate was correct for one turbine.

Are you playing Devil's Advocate today?

        Would be worth building test units to try out the concept. (n/t) - TB - 9/12/2007 1:38:32 PM
