A 6-month long public exhibition of a Toyota concept home—one aspect of which is a plug-in Prius—ended Sunday in Japan. Designed and developed by TRON (The Real-time Operating system Nucleus) project leader Ken Sakamura in cooperation with Toyota Home K.K. (Toyota is also a home builder), the Toyota Dream House PAPI is serving a testbed for an environmentally friendly, energy-saving intelligent house design built with the latest ubiquitous network computing technologies created by the T-Engine project.
Toyota Dream House PAPI was designed to interface with other Toyota technologies—one of the most important being the Prius. In the house concept, the hybrid can be used as a generator to provide electricity to the intelligent house for up to 36 hours in an emergency, such as an earthquake that cuts off normal electrical supplies.
Conversely, the house can supply electricity to the battery packs of hybrids or electric vehicles via the stand in the middle of the garage. Some of that electrical energy can be obtained from solar cell panels that cover the roof, plus the sides of the structure. The house also uses solar heating and fuel cells, making it a hybrid energy house.
The concept house highlights technologies projected to be in use in 2010. No detail on the plug-in attributes of the Prius yet available.
Toyota has proposed the use of the Prius as an auxiliary generator before. In February, at the annual meeting of the National Rural Electric Cooperative Association, Toyota announced it would lease a modified Prius that could provide 3 kW at 120 volts to a rural electric cooperative in Oklahoma for field and market testing.
