It’s not mainly about the hardware anyway! ◊ To be sure, energy-saving technologies get not only cheaper but also more powerful ◊ Not just the wizardry of nanotech & catalysis, of microprocessor controls and new materials ◊ Even more importantly, the mundane (next two slides) and the unexpectedly basic (3 rd ) ◊ But most importantly, the design revolution that artfully combines well-known technologies to turn diminishing returns into expanding returns—making very large energy savings cost less than small or no savings ◊ Add that to new tech and the mind boggles…
1. Electromechanical actuators (rotary and linear, all sizes) ◊ Prof. Delbert Tesar, UT/Austin, is doing for EM actuators what Gordon Moore did for chips ◊ Equipping an aircraft carrier with modern electric actuators, replacing hydraulics in 12 main applications, would save: 1.4 million pounds (weight reduced 3.2×) 500 billets (personnel reduced 2.9×) 61,000 square feet (space reduced 9.2×) Maintenance (reduced 2.7×, complexity 2.2×) $20–25 million/y of operating cost ◊ Order-of-magnitude improvements in power density, reliability, and precision; same/less cost ◊ Most if not all of what’s now done with hydraulics is better done with electrics
