Honda's Smart Home project sits at the center of this short film, a real house built on the UC Davis campus in California designed to produce more energy than it uses. Cameras walk through the structure showing rooftop solar panels, a geothermal heat pump buried in the yard, and a garage wired to charge an electric car directly from the home's own power supply rather than the grid. Engineers and researchers explain the thinking behind each system, from insulation choices to how the house tracks its own energy balance over a full year, aiming for a true zero-net-energy result rather than just efficiency gains. The film treats the house as a working prototype rather than a showroom piece, following how residents actually use the space and how the systems perform under everyday conditions. It is a compact look at what a car manufacturer's research division does when it turns its attention from vehicles to the buildings those vehicles park in, and at how close current technology already comes to a self-sufficient home.
