Heat Conversion
Technique Found
(
Beersheva (JTA) — A Soviet-
born Israeli scientist at Ben-
Gurion University of the Negev
has demonstrated the process of
converting heat to electricy from a
power plant with no moving parts.
Prof. Herman Branover and his
team unveiled the "Etgar 3"
(Challenge 3), the first semi-
industrial liquid metal MHD
(magnetohydrodynamic)
generator, last month on the cam-
pus of the university.
Branover said his heat-to-
electricity process, the result of
seven years of scientific research,
is "ahead of both the United
States and the Soviet Union, who
have been working on this princi-
ple for 20 years." Magnetohyd-
rodynamics is the science behind
Branover's unique power plant
that can run on any heat source
and can save up to one-third on
conventional fuel usage.
The development of the
generator was financed by Sol-
mecs, a British-Israeli corpora-
tion, and Israel's Trade and In-
dustry Ministry. Peter Kalms,
managing director of Solmecs,
said he has been in touch with
several prospective purchasers
with "available funds, current
needs and the right attitude
toward innovation." These in-
clude the Southern California
Edison Co.
Dr. Michael Petrick, program
director for fossil energy at the
Argonne National Laboratory
outside Chicago, which cooper-
ated closely in the resarch for the
generator, said it can operate
under a wide spectrum of heat
conditions, with some 66 percent
efficiency — a very high percent-
age of use of available heat, and
far higher than conventional
methods. Argonne is one of the
U.S. Department of Energy's
major multi-purpose laboratories.
The Branover system is unique
among MHD generators in that it
uses liquid metal flowing between
two poles of a magnet to generate
electricity at relatively low tem-
peratures of 100 to 300 degrees
centigrade. The U.S. and Soviet
MHD generators, still in the ex-
perimental stage, use ionized gas
heated to 3,000 degrees centig-
rade.
Branover said he sees "Etgar
3," which generates 10 kilowatts
of power, as the final stage before
the construction of industrial
power plants capable of generat-
ing as much as 10,000 kilowatts of
electricity.
According to Branover, "The
main advantagd of the method is
its efficiency. Under optimal con-
ditions, it can create a specific
quantity of electricity from two-
thirds the quantity of fuel re-
quired in other methods."
Branover pointed out that power
stations already in operation
make huge investments to in-
crease efficiency by only a fraction
of a percent for vast savings in
fuel. In a small country like Is-
rael, saving just one percent in
fuel could mean saving hundreds
of millions of dollars.
