charge-sustaining distinction is not of practical use in hydraulic or mechanical hybrids, as very little energy can be stored in an accumulator or a flywheel, although during the PNGV
years there was significant effort made to develop commercial flywheel batteries that would be capable of storing significant energy.
As a White House press release noted, the PNGV
presented "a technological challenge comparable to or greater than that involved in the Apollo project" (White House 1993).
Under the terms of the agreement, PNGV
will participate in the deepening of the 7-32 well from 5400ft to intersect a large seismic target at 7,500 ft.
In recent years, PNGV
support for fuel cell--related technologies increased significantly.
Taking into consideration the successes, degree of progress, and lessons learned in the PNGV
program to date, government and industry participants should refine the PNGV
charter and goals to better reflect current societal needs and the ability of a cooperative, precompetitive R&D program to address these needs successfully.
Using the two sources of power -- the electric source and the heat engine -- you can design and control the hybrid in a variety of different ways regarding when you use the electric and when you don't," says Bob Culver, executive director of PNGV
Environmentalists say the PNGV
has also focused on developing the wrong technologies, including diesel engines which will not meet California's tough emissions standards.
All told, the PNGV
involves more than 400 organizations in 38 states.
The whole effort of PNGV
is comparable to our race to the moon in terms of the coordinated effort," says Roy Collins III, staff counsel of commercial affairs at Chrysler, and one of several African Americans working with Carson on this collective project.
Light weight vehicles and a more efficient powertrain are viewed by the PNGV
as the surest way to reach the technology development goals.
[Partnership for the New Generation of Vehicles] is trying to determine what are going to be the best technologies to produce an 80-mile-per-gallon car that the government has challenged them to do.
program, however, has run out of gas -- due to a lack of federal funding and a lack of interest from the Big Three automakers, which realize that lightweight, fuel-efficient cars will undermine their profit base.
