Comment on 'Windmill': China tests world’s first megawatt-level airship to capture high winds
Redjard@lemmy.dbzer0.com 2 weeks agoIt is actually a notable fraction (~60%) and more importantly constant.
Meaning if your wind has 27x more energy, you can also capture 27x more energy.
This is the energy taken from the wind passing through the disk the turbine spins in, so turbines are placed in spaced out rows to let the wind mix with all the air that didn’t pass through a turbine and pick up speed again.
