The Partnership for a New Generation of Vehicles (PNGV) receives one of the biggest percentage increases (22%) in the Clinton budget. A total of $277 million in federal funds is proposed for the program to develop the so-called Supercar--a vehicle with very low emissions and up to three times the fuel efficiency of today's cars. The fattest chunk of the federal budget for PNGV, $164 million, goes to the Department of Energy. The government and the Big Three automakers share PNGV costs. A breakdown of the Administration's budget for PNGV reflects a recent decision to concentrate R&D on four key systems: hybrid electric vehicle drives, direct injection engines, fuel cells, and lightweight materials. On the other hand, funding falls for projects now considered less promising--gas turbines and ultracapacitors. The budget also retracts from further federal research into areas that appear to have commercial applications and have reached a proprietary point.
Researchers working with additive manufacturing have said multimaterial techniques will allow industry “to fabricate materials with combinations of density, strength, and thermal expansion that do not exist [yet].”
The term "multiphysics" is used to describe the simulation of multiple types of physics and their influence on one another -- for example, the investigation of the behavior of a chemical in liquid form will involve both chemistry and fluid dynamics.
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.
