New dirigibles are power plants in the sky:
We wonder if a floating wind turbine generator (translated) like this one would alleviate some of the complaints we hear about ground-based turbines. This huge helium-filled structure is designed to generate electricity at high altitude, where winds are stronger and blow much more consistently than near ground level. We’ve read complaints at the unsightliness of wind farms, and the noise that they make as the turbines spin. A test run took place at only 350 feet, but this generator is meant to fly at an altitude of 2000 feet. We’d bet it’s much less obtrusive and much quieter at that distance.
There isn’t a whole lot to the lighter-than-air assembly. It’s got an aerodynamic balloon with stabilizing fins, and a propeller attached to a generator at the center. The tether that holds it in place also carries the conductors which translate the power down to the ground. There is mention of a fail-safe system that allows for a slow descent if it get gets away from its tether, so you shouldn’t have to worry about the sky falling on you.
It’s certainly an interesting idea. For some reason this makes us think of the space-based solar generator panels found on Larry Niven’s Ringworld.
