Green energy system could power the home and car

A wireless green energy system to supply the home and the car is being designed by University of Auckland

The proposed green energy system would harness and integrate renewable energies, such as solar and wind, to power a house and an electric vehicle. The first working model of the concept is being built in the Faculty of Engineering over the next three years.

“Household renewable energy systems need a very large battery to store power, which usually cost tens of thousands of dollars, on top of the cost of installing solar panels or wind turbines,” says Duleepa, from the Department of Electrical and Computer Engineering. “The concept here is to use an electric vehicle, which already has a powerful battery, to store some of the power for the system. This would make its installation much more financially viable.”

While such systems may be many years off, the project aims to demonstrate that they can work in practice. The system would make use of emerging technologies in wireless power transfer and intelligent power management. In comparison to existing systems, it would be more cost effective, safer and versatile. Duleepa intends to develop new technologies in bi-directional power transfer and new circuitry techniques to improve the efficiency of the system.
