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. So, this begs the question; with the price of energy constantly increasing and with […]
