Battery-maker, Electro Energy Inc., joined the Plug-In Hybrid Consortium in Washington, D.C. in May to demonstrate the power of Plug-In Hybrid Vehicles (PHEVs) to senators and representatives who were meeting to discuss alternative energy. One of the vehicles demonstrated was a Toyota Prius powered by Electro Energy's bi-polar NiMH battery which is capable of driving 20 to 25 miles on a single battery charge without using any gasoline, the equivalent of over 100 miles per gallon of fuel economy. Further driving range is possible in the normal hybrid operating mode.
Plug-In Hybrid vehicles are designed to be powered solely by battery power for some period of time, significantly reducing gasoline consumption. The only infrastructure required to run the vehicle is a three-pronged extension cord for recharging the battery from a household electric outlet.
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.
