Just like the Big Bang, we have huge energy in a small space.

正如宇宙大爆炸一样，我们在一个小空间里面有巨大的能量。

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。

So, similarly in a case where instead we have a small energy difference, we're going to have a low frequency, which means that we're going to have a long wavelength here.

在这个例子里,能量差较小,我们得到的频率低,这意味这它的波长更长。

In my opinion, like solar energy, the greatest opportunity for the technology is in providing energy for small communities rather than as some attempt to preserve the energy status quo, which is simply unsustainable without fossil fuels, including gas.

To get clean energy to them requires a decentralised approach using local resources such as wind power, solar energy or small hydroelectric projects.

ECONOMIST: Change of environment

Alternative energy only accounts for a small percentage of energy sources, but the onset of peak oil will force society to look elsewhere to meet its energy needs.
