Bamboo propeller

(take koputā /竹蜻蜓) is a fictional tool in Doraemon manga that allows users to fly into space. Attach the propeller to the body of this bamboo, and the wearer to fly freely wherever he wants.

How it works

Every time the propeller was spinning he will issue the gravitational energy, and energy will be through the entire body. So the user will be like floating Earth because gravity does not affect him. Then the brain waves will adjust the change in rotor speed with the intermediary computer. Change the play speed of this propeller that causes the displacement area opposite the gravitational force, a change that allows us to move freely.

If you have 8 hours battery bamboo propellers will die alone, but if rested for 20 hours, the battery it will work again.
