The ecopower micro cogeneration system (microCHP) uses a propane generator. The unit produces as much as 4.7 kW with as much as 90% total electric and thermal efficiency. It reportedly serves as a reliable heating and electricity source in locations compromised by the absence of gas mains and reliable power grids. The system is said to emit significantly less carbon dioxide than a traditional power plant.
