Engineers at Ohio State University are developing a computer control system that improves the fuel efficiency of hybrid gasoline-electric vehicles. Road tests on a Chevy suburban SUV show a 50% increase in fuel efficiency. "The work demonstrates that energy-efficient hybrid cars can retain the high-performance feel of traditional gas-powered vehicles," says Giorgio Rizzoni, professor of mechanical engineering. Based on numerical simulations and in-vehicle tests, the engineers created a computerized control system that relies on algorithms for optimizing the power split between engine and electric motor.

Using a 3D printer, CNC router, and existing powertrain components, a team of engineers is building an electric car from scratch on the floor of the International Manufacturing Technology Show in Chicago this week.
In November, a European space probe will try to land on the surface of a comet moving at about 84,000 mph and rotating with a period of 12.7 hours. Many factors make positioning the probe for the landing an engineering challenge.
NinjaFlex flexible 3D printing filament made from thermoplastic elastomers is available in a growing assortment of colors, most recently gold and silver. It's flexible and harder than you'd expect: around 85A (Shore A).
