就如同一个荒岛四面环水一样，丰富的能量以风、阳光、潮汐和热的形式就存在于我们身边。
As with the water that surrounds a desert island, there is abundant energy right under people's noses, in the form of wind, sun, tides and heat.
Minesto还强调到，这种机器其中一个最大的优点是它相对于其他潮汐发电机是十分小的，仅仅是12米长的风翼和1米的发电机。
One of the big advantages of their technology, Minesto executives say, is its small size — 12 meters for the wingspan and one meter for the turbine — relative to other tidal-energy designs.
但是潮汐流远比风容易预测，这意味着公共事业公司利用潮汐时不必担心意外的无风天。
But tidal streams are far more predictable than wind, which means utilities using tidal don't have to worry about unexpected still days.
