Scientists at Stanford University have created a battery which can produce electricity from water - and which could be used where rivers meet the sea to create clean energy on a massive scale.
Dan Matthews says it can be connected to almost any battery for enough of a charge to clean twelve liters of water.
丹*麦修斯称该装置几乎与任何电池相配。 在电池电量充足的情况下可以净化12公升的水。

By ensconcing the lithium inside the membrane's seal, the PolyPlus battery reacts safely with the oxygen dissolved in the water and delivers as much as 1,300 watt-hours per kilogram of electricity.
