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。

There is also a new steering wheel with an energy-absorbing rim to cushion the driver's head in the worst impacts.

还有新式方向盘，其边缘具有减震功能在最严重的冲击中缓冲保护司机的头部。

That energy powers motors in both the front and rear wheels, which are split so that they're bisected by swing arms that connect to the wheel hubs.

这些能量可以驱动前轮和后轮的马达，之所以分开马达，是因为这样它们的能量就可平分到连接车轮轮彀的摆臂。

The downside is that the process to arrive there can waste a lot of time and energy in reinventing the wheel, when, depending on the problem a school is trying to solve, the level of freedom it has to solve it, and the type of team it deploys to attack it, there is some predictability to the blended-learning model it is likely to adopt.

Another project, the Copenhagen Wheel, is a bicycle wheel that stores excess kinetic energy that it can later disperse to give riders an extra boost when going up hills.
