According to Extreme Tech, Honda and Climate Energy have developed a freewatt micro-combined heat and power cogeneration system for homes. The system includes a cogeneration unit made by Honda that produces 3.26 kilowatts of heat and 1.2 kilowatts of electric power that can be coupled with either a furnace or boiler made by Climate Energy. The companies say that the system can save the average homeowner up to $1,000 a year on energy expenses, even more if the system is integrated with net metering, which allows homeowners to sell unused electric power back to the central grid. The new system will initially be rolled out in the Northeast due to the region's high heating demands.   EC
