Abstract
The multiaxel windmill has multiple blades attached to a rim that rotates on multiple wheels rather than about a single axel. The blades are many and short and positioned far from the axis of rotation such that the full blade length rotates at maximum velocity. This allows blades to be oriented for high-efficiency lift. This design is more easily scaled to large power because larger weight and more blades are easily supported. A starter motor permits use of optimum-efficient, pure-lift blades, and no blade twist and double-end support enables those blades to be simpler, lighter, and cheaper. Multiple blades surrounded by supports are easily seen and avoided by birds.
