车轴连接到这个车轮的外臂,外臂开始以每分钟1/8转的速度旋转。
It takes just 1.5 kilowatt-hours (5.4 M J) energy to rotate the Wheel -roughly the same as boiling eight small domestic kettles of water.转动轮子只需要1.5千瓦时(5.4兆焦耳)的能量,这与使用8壶家用小水壶的能量大致相同。
If I am going to buy a car, I'm going to assume they all have wheels that rotate forward and backward on demand and they have a steering wheel, a gas pedal, and a brake pedal that work.如果我要买车,我会假设它们全部都有符合要求的前后轮、方向盘、油门和刹车。
