Shock Wave Engine for Cars gets closer
Despite several attempts to take technology in a different
direction, Gottlieb Daimler's century-plus-old still invention of
the internal combustion engine still reigns supreme - though it's
not been for a lack of trying.
In the mid-1990s, for example, the noted technology venture
capitalist Ben Rosen gained attention for an ambitious plan to
commercialize an engine alternative which featured a small
turbogenerator and a carbon-fiber flywheel. He was even able to
demo the technology for a road test. But the idea failed to catch
on and after four years and $24 million down the drain, Rosen and
his brother (who had co-founded Rosen Motors), decided to shut
down their project after failing to interest any big automakers.
But with $4 a gallon gasoline signs moving from worst-case
scenario to no big deal anymore, the impetus to invent our way out
of the energy crisis remains stronger than ever. And now, a team
of researchers is reporting progress for an idea featuring a
prototype generator for hybrid automobile engines that does not
use pistons, crankshafts or valves.
If it works as advertised, the so-called Wave Disk Engine would
use
shock waves to more
efficiently compress fuel and transmit energy. The
research team at Michigan State University claims that its
prototype could potentially
decrease
auto emissions by up to 90 percent. The invention, which
doesn't have a radiator or valve
train, uses a generator connection to serve as a vehicle's
engine, according to Norbert Mueller, an associate
professor of Mechanical Engineering at MSU.
The idea here being that
compression becomes more efficient if there are no moving parts
involved in the process. The MSU team contends that their
prototype thus would more efficiently process automobile fuel.
What's more, they estimate it
would
subtract almost 1,000 pounds from the weight of a car
that now gets taken up in the way of a conventional engine,
transmission, cooling system, emissions, and fluids. Vehicles
incorporating the system would be able to run on myriad fuels -
including compressed natural gas, hydrogen, gas or renewable
fuels.(You can listen to Mueller explain this in more detail in
the above video filmed a couple of years ago when MSU received the
grant to undertake the project).
The prototype was presented last week to the Advanced Research
Projects Agency Energy,, which is backing the Michigan State
University Engine Research Laboratory with $2.5 million in
funding. Also, check out this 2008 paper on wave disk technology.
