Toyota Dream House Toyota Dream House PAPI was designed to interface with other Toyota technologies. One of the most important of those other technologies is Toyota Motor Corporation's Prius hybrid sedan, which can also be used to supply electricity to the intelligent house for 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 the 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, which makes it a kind of hybrid energy house. http://tronweb.super-nova.co.jp/toyotadrea...mhousepapi.html
My favourite quote: " the house can supply electricity to the battery packs of the vehicles via the stand in the middle of the garage. " Looking at that picture, a Prius is parked next to the charging station. Does that mean Toyota have in mind a plug-in hybrid version of the Prius in the future?
