Delphi's new solid oxide fuel cell
The DOE is pushing SOFCs as a way "to generate electrical power more cleanly and efficiently for a wide variety of stationary and mobile power applications." Delphi says that, "heavy-duty trucks will be able to utilize SOFC auxiliary power systems for both heat and electrical power when parked, to save 85 percent of the fuel that today they consume when idling their main engine, and likewise reduce idling emissions." SOFCs won't reduce all our energy use by 85 percent, but there are a lot of idling trucks out there.
