We see
it at rest stops and truckstops across the country. Big rigs in formation
with
diesels idling to generate electricity for the lights, cab and sleeper
while keeping the oil and the operator warm. Practical? Maybe. Eight hours
of all-night idling can consume 8 gallons of fuel.
At $1.30/gallon, it won’t break the budget. Efficient? Hardly.
Idling
diesels consume 1.2 billion gallons each year. Researchers at DOE’s
National Energy Technology
Laboratory are developing a bolt-on
diesel-fueled solid oxide fuel cell concept that generates electricity
and provides heat to keep the rig ready to roll, all at about 50 percent
efficiency with no pollution.
