Detroit-In a setback to use of so-called zero-emission vehicles, early March found General Motors recalling its 1997 Generation I EV1 electric cars and 1997-98 S-10 Electric Trucks. The company says the vehicles were produced with a charge port that may fail during charging. If this occurs, heat could build up within the port and a fire result. GM's advanced technology group says that although the small part can be replaced in the pickups, the more complex EV1 installation precludes repair. The notice said the company would assist in termination of the lease, and "discuss your immediate transportation needs."
Generation II, 1999 EV1s were not involved "due to their uniquely different charge-port design." The company says electric vehicles are still very important to GM.
Conventional wisdom holds that MIT, Cal Tech, and Stanford are three of the country’s best undergraduate engineering schools. Unfortunately, when conventional wisdom visits the topic of best engineering schools, it too often leaves out some of the most distinguished programs that don’t happen to offer PhD-level degrees.
Airbus Defence and Space has 3D printed titanium brackets for communications satellites. The redesigned, one-piece 3D-printed brackets have better thermal resistance than conventionally manufactured parts, can be produced faster, cost 20% less, and save about 1 kg of weight per satellite.
