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.

A Tokyo company, Miraisens Inc., has unveiled a device that allows users to move virtual 3D objects around and "feel" them via a vibration sensor. The device has many applications within the gaming, medical, and 3D-printing industries.
In the last few years, use of CFD in building design has increased manifolds. Computational
fluid dynamics is effective in analyzing the flow and thermal properties of air within spaces. It can be used in buildings to find the best measures for comfortable temperature at low energy use.
