Does Apple's iPhone really have "an application for everything?" Benson Hougland thinks so. He built his own energy monitor for use in his home. A programmable automation controller, a power-monitoring I/O module, and two current transformers let him measure current and voltage to provide power-use data in real time. And Benson can tap into his system to collect power-consumption data from anywhere and view it on his Apple iPhone. The result? An interactive, real-time awareness of energy use that helped him save $200 a month on his power bill.
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.
