Hydraulic hybrids

Very interesting idea: using a hydraulic system to store and provide energy for a truck:

In the next few months, United Parcel Service (UPS) will begin testing an automotive breakthrough that comes straight from the Environmental Protection Agency. UPS will launch two prototype delivery trucks whose ordinary-looking brown exteriors mask an exotic assembly of pumps, tanks, and high-pressure hydraulic fluids. Working in concert with a diesel engine, these novel parts will replace the transmission and other standard components.

The big brain behind such “hydraulic hybrid” vehicles is Charles Gray, a top scientist at a laboratory the EPA operates in Ann Arbor, Mich. Barack Obama may never have heard of hydraulic hybrids, but such fleets could go a long way toward meeting goals the President-elect has spelled out in many speeches, says Gray, whose team has racked up 60 patents on green automotive technology. The payoff is not just cleaner air, he says, but something “very important right now—jobs for Americans.”

It was UPS that proposed a joint research project in hydraulics when it learned of the EPA’s efforts back in 2004. After studying the agency’s work, UPS concluded that this sort of hybrid truck, when mass-produced, would cost about $7,000 more than standard delivery trucks, which run $40,000 to $50,000. But the EPA said savings on fuel and maintenance over the life of the truck could be as much as $50,000, while reduction in carbon dioxide emissions would be 30% or more. “I think we’re going to be able to help the environment, but certainly it’s going to be a good business decision, too,” says Robert Hall, a UPS vice-president versed in the hybrid project.

If the upcoming trial goes well,  …
