燃料效率

This "atmospheric engine," invented by Thomas Savery and vastly improved by his partner Thomas Newcomen, embodied revolutionary principles, but it was so slow and wasteful of fuel that it could not be employed outside the coal mines for which it had been designed.

但其效率低下且浪费燃料，无法在煤矿以外的地区使用，这与最初的设计期望背道而驰。
