Distributed electric power generation
First Claim
1. A high efficiency electric power generating system that includes a combination of a high efficiency motor vehicle and a household, where said high efficiency motor vehicle is parked for a substantial total time duration in a day in proximity to said household, where said high efficiency motor vehicle includes a low powered heat engine and an electric power generator driven by said low powered heat engine, where electric power produced is suitable for propulsion of said high efficiency motor vehicle, where said household has a capacity to use heat in heat using devices,where there is an excess of heat that is a difference of heat produced in said heat engine by burning of fuel and a heat equivalent of electric energy generated, where said generating system includes heat transfer means that enables substantial transfer of said excess of heat to said household,where said low powered heat engine produces a quantity of said excess of heat that does not significantly exceed said capacity to use heat, and said excess of heat replaces a like quantity of heat that is consequently not produced by burning fuel at a place other than in said heat engine for benefit of said household,where said electric power generator produces electrical energy while said motor vehicle is in said proximity to said household, and said combination enables a distributed electric generating system that maximizes use of energy from burning fuel.

Abstract
An electric power generating system is arranged such that the system efficiency approaches 100%. In the context of this special arrangement, system efficiency is defined as the electrical energy produced divided by the amount of heat energy allocated to its production. All heat energy that is not converted to electric energy is completely used by an associated household. However, high efficiency requires that heat usage by the household is not increased as a result of this arrangement. Unlike most electric power generation, heat is not wasted, so there is no inefficiency.
The motor vehicle includes an electric generator driven by a heat engine, with an optional natural gas connection to the household. The heat from the exhaust and the engine coolant is connected to household devices that make full use of that heat. As needed, operation of the heat engine is regulated such that heat discharge rate does not exceed the rate at which household devices can use that heat. Generated electricity charges vehicle batteries, with surplus going to the household and to the public utility.
