The electrolysis efficiency is high when voltage grad is high and original concentration is low.

从电解效率来说，电压梯度越高去除率越高，初始浓度越高去除率越低。

Overall efficiency of the system is extremely low currently, thanks to a low concentration of those photon-catching structures, but individually they capture about 40 percent of the light's energy, meaning a higher concentration could make for very hearty soup indeed.

Additionally, its chief financial officer, Tim Sloan, said that the performance reflected its steady concentration on long-term metrics, such as ROA and ROE, as it improved its efficiency ratio of 57.1 percent, well within its target range of 55 to 59.
