WILL THE HYPER-CAR BE THE WAVE OF THE FUTURE?
By William Golove

 
On March 7, 1995, Amory Lovins, Director of Research at the Rocky 
Mountain Institute and internationally recognized expert on energy 
efficiency, spoke at an Energy and Resources Group brown bag lunch.
	Lovins discussed his most recent research project, the "hyper-car." 
Although a couple of pre-prototypes have  been built, this personal 
vehicle is still largely theoretical. It is projected by Lovins to 
achieve fuel efficiencies ranging from 200 to 1000 miles per gallon by 
using advanced composite materials for the body and a hybrid electric 
drive system.
	The basic engineering principle behind the design of the hyper-car comes 
from Lovins' earlier work on energy efficiency in buildings which he 
introduced by displaying a supply curve of conserved energy. This curve 
incorporates his notion of "tunneling through the cost barrier." He 
explained this concept by suggesting that there were declining marginal 
returns to efficiency investments until a synergy was achieved, at which 
point marginal returns dramatically increase.
	An example of such a synergy might be the introduction of efficient 
lighting, advanced wall-construction materials, daylighting, and super 
efficient windows into an office building. The individual effect of each 
item on improved energy efficiency is small. Taken together, however, 
they may greatly reduce or completely eliminate the need for an 
air-conditioning unit. Thus, the combined result is an enormous savings 
in both capital and energy.
	Lovins then showed how the idea of engineering synergies provided the 
framework for the hyper-car. In short, use of advanced composite 
materials for the vehicle's body and hybrid electric motors for 
propulsion result in a dramatic decrease in vehicle weight and increase 
in fuel efficiency. Lovins contended that such vehicles would be safer 
than those currently on the road since, unlike today's steel bodies and 
frames, auto bodies of the new composite material would not buckle inward 
with dangerous jagged edges. Also, energy-absorbing crash structures in 
the bodies would absorb a substantial amount of the energy transfer from 
a crash, and advanced, computerized braking and steering systems would 
reduce the incidence of accidents altogether. Lovins also stated that the 
hyper-car would also offer straightforward re-manufacture potential as 
future technologies evolve, and would be completely recyclable to the 
extent that re-manufacture is undesirable.
	Lovins went on to say, however, that these  vehicles would not solve 
traffic congestion. In fact, he said, they might exacerbate the issue. 
The increased efficiency of the new vehicles would make driving 
significantly cheaper, thus allowing those whose total driving is 
currently constrained by cost to drive as much as they want. Lovins 
speculated that a cross-country drive in the hyper-car would require only 
a single tank of gas. He offered no suggestion as to the resolution of 
the congestion problem, however. Lovins expects the hyper-car to be 
commercially available as early as 1997 or 1998.
	Lovins concluded his presentation with a question and answer session. 
One of his more provocative comments, made in response to a question from 
an ERG Ph.D. student, was that he expected the current electric utility 
industry to be obsolete within five years as distributed generation 
replaces central power station generation of electricity. Although his 
claims and predictions are undoubtedly controversial, Lovins continues to 
present a visionary perspective on possible, future patterns of energy 
consumption.
