The Physics of Windmill Design

Опубликовано 2 марта 2021, 14:00

This video was created in partnership with Bill Gates, inspired by his new book “How to Avoid a Climate Disaster.” Find out more here: gatesnot.es/3u7UUVU

This video is about how physics dictates the design of modern windmills - why they are so big, have so few blades, and have such skinny blades.
