Do High-efficiency Motors Save Energy?
2009-06-17 14:16:00 Motor efficiency is not a single number; it depends on how the motor is used. Most efficiencies are measured at 75% output. What if the motor is used at 50% output? Or 90%? Or what if the load is highly variable? Part of the energy savings comes from reduced motor slip — but this actually rais

Should General Motors keep several models including the G8 from brands bein
2009-04-28 23:43:00 With General Motors announcing that they are accelerating there revised Viability Plan which will focus on four core brands in the U.S. - Chevrolet, Cadillac, Buick and GMC - with fewer nameplates and a more competitive level of marketing support per brand. At the same time will moves up the resolution of Saab, Saturn, and Hummer to the end of 2009 and phase out the Pontiac brand by 2010.This not only got me thinking, but has a number of people thinking about what is going to happen to some of these vehicles under the phased out brands. For example, you have Hummer, Saab, Saturn and now the phased out by 2010 Pontiac, but the problem is while GM doesn’t need even four brands, they need two or three max they do need some well selling vehicles under those few brands. Pontiac has the G8 and the Solstice, Saturn has the Aura and Vue including the hybrid and I would be surprised if they didn’t save one Hummer, either the H2 or the H3, but as a diesel power plant.One suggestion from t...
