Politcal correctness aside there is no question that adding an additional power system to a hydrocarbon combustion plant also adds additional waste.
Pound for pound it takes more fuel to move a hybrid per foot poound of travel than it does to move a vehicle with a signle stage power system.
With a Hybrid one is also adding the waste of generation which includes the additional friction losses of driving a generator as well as the standard generator efficiencies encountated as an industry standard. These are generally no better than 80 percent adding rougnly an additional 20% loss to a process that is aleready terribly inefficient.
Altair has released an update of its HyperWorks computer-aided engineering simulation suite that includes new features focusing on four key areas of product design: performance optimization, lightweight design, lead-time reduction, and new technologies.
At IMTS last week, Stratasys introduced two new multi-materials PolyJet 3D printers, plus a new UV-resistant material for its FDM production 3D printers. They can be used in making jigs and fixtures, as well as prototypes and small runs of production parts.
In a line of ultra-futuristic projects, DARPA is developing a brain microchip that will help heal the bodies and minds of soldiers. A final product is far off, but preliminary chips are already being tested.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
