Archimedes principle (truck) wind turbine.

In today's era, we harness electricity from wind, sun, and water through devices like windmills, solar panels, and hydroelectric dams. These innovations have revolutionized energy production. However, a concern arises when there is insufficient wind speed for domestic windmills to function efficiently. To address this issue, I propose a unique windmill design tailored for truck drivers who spend long hours on highways. This windmill, mounted on the semi-trailer using a powerful magnet, can generate sufficient electricity during a 5-hour cruise at 70 km/h. The generated energy can power appliances in the driver's cabin, such as microwaves and fridges.
