Key distinction with all other technologies examined so far: FC is not a technology for exploiting/utilizing a specific energy resource . Rivers: hydropower Wind: wind turbines Hydrocarbon fuels: heat engines (gas turbines, Stirling) Solar energy: active, passive solar heating, photovoltaic, Stirling cycle. Are not FC another way of utilizing HC fuels?

Direct use of HC fuels in fuel cells has unresolved technological problems, and is not currently practical. Indirect use of HC fuels in FC – in which the fuel is first converted to a form (i.e., hydrogen) that is practical for FC – is of questionable merit with regard to broader (energy and environmental) issues. Fuel cells use H
