Focus on Energy

摘要

This is what we know: An electro-mechanical system can operate at about 96% overall efficiency. A typical hydraulic system will operate at about 78% overall efficiency. Down at the bottom of the list we find that a typical pneumatic system is about 6% efficient. With the price of energy constantly increasing and with the pressure to "go green," why would anyone in his right mind choose to use fluid power as a means to do work?
