PEACE Special Work
CORPS ^or Special People
Peace Corps volunteers are
people pretty much like you. Peo
ple with commitment and skills who
have assessed their lives and decided
they want to be of service to others
in a troubled world.
The problems our volunteers
deal with overseas aren't new. Such
as the cycle of poverty that traps one
generation after another because
they're too busy holding on to get
ahead. The debilitating effects of
malnutrition, disease, and inade
quate shelter. Education and skills
that are lacking, and the means to
get them too.
Your college training qualifies
you to handle more of these prob
lems than you might think. Such as
teaching nutrition and health prac
tices; designing and building bridges
and irrigation systems; working on
reforestation and fisheries pro
grams; introducing better agricul
tural techniques; advising small
businesses and establishing coopera
tives; or teaching math and science
at the secondary level.
The number of jobs to do is
nearly as great as the number of vol
unteers who have served since 1961;
Nearly 90,000. More volunteers are
being chosen now for two-year
assignments beginning in the next
3-12 months in Africa, Asia, Latin
America, and the Pacific.
Our representatives will be
pleased to discuss the opportunities
with you.

Inventor and physicist Eldon Haines demonstrates his solar-powered water heater that re
quires no electricity and has only one moveable part.
Sun lands inventor in hot water
By Michael Doke
Of the Emerald
When Eldon Haines finds himself in hot
water, he just has to look toward the sky. He
knows it's gotta be a sunny Oregon day.
Haines, a local inventor and physicist, has
developed a way to heat water without using elec
tricity. In fact, his geyser-pump solar collector on
ly has one moving part.
“It's an elegant solution to a nasty problem,"
he sdid Wednesday night in Lawrence Hall.
Haines will demonstrate the design at the Solar
'83 Energy Product Show Eriday and Saturday at
the Eugene Hilton Conference Center.
Operating like a natural geyser or a coffee
pot, Haines' system gets its power from boiling
water with the aid of the sun.
Water slowly travels upward through a solar
collector until it reaches the boiling point, he said.
The hot water is than forced down copper tubing
where it flows into a solar heat exchanger. Here it
warms fresh water in a large storage tank.
A vacuum develops as cooler water leaves the
exchange area and passes through a vapor con
denser. From here the original water returns to
the solar collector to start the process over,
Haines said.
Haines, of Bohemia Solar and Scientific, Inc.,
Eugene, said the lack of moving parts makes for a
more efficient system. A check-valve, or flapper
device, that keeps water from backing up is the
only moving piece.
Low costs in both initial set-up and lifetime
maintenance of the geyser-pump system could
make it competitive with the popular electrical
powered systems, Haines said.
The system could also be used in areas
without electricity and could be a technology ex
ported to other nations, especially third-wprld
countries, he said.
In the Northwest, Haines' device could be us
ed to store hot water for days, he said. The
geyser-pump can gather solar energy even on
cloudy days, retaining almost half of the heat
reaching its collectors.
Haines admits his system is not as efficient as
conventional, externally pumped designs. The
geyser-pump moves water only 65 percent as fast
as the electric model and relies on solar heated
water for power. But his invention is new and will
develop with technology, he said.
And Haines will stand by his solar system.
"We are almost hoping for a cloudy day at the
show this weekend. We can at least collect warm
water and show that the system works."
Seminars focus on solar energy
"Putting the Sun to Work" is the
theme of the Solar Energy Associa
tion of Oregon's annual con
terence, to be held at the Eugene
Hilton Friday and Saturday.
Donald Aitken, chairer of the
American Solar Energy Associa
tion, and Rep. Jim Weaver, D
Oregon, will be keynote speakers.
A variety of seminars about
energy conservation and
renewable resources will be of
fered, says Allen Brown, executive
director of SEAO. Conference
hours are from 9 a.m to 5 p.m.

Dr. Benjamin Spock will be speaking on
both days.
The conference is being held in
cooperation with the University's
Solar Energy Center, Lane Com
munity College and Lane County.
Registration fees are $30 for one
day and $50 for both days. One
hour of graduate credit is
available from the University's
Continuing Education program
for an additional $24. For details,
call 686-3696.
Local food drive
to help Eugene's
hungry residents
The campus hunger-action
group will be collecting food
Saturday in conjunction with the
United Nations-sponsored World
Food Day.
Last year's food collection day
brought in "one and a half Toyota
liftbacks" of food for the needy,
says Amy Clark, a coordinator of
the event.
"By doing this in conjunction
with World Food Day, we want to
show that there's hunger in Lane
County as well as hunger around
the world," Clark says.
The collection will take place at
Albertson's on West 18th from
9:30 a.m. to about 6 p.m. Saturday,
Clark adds. The hunger-action
group will have an organizational
meeting at Koinonia Center
(across from PLC) at 3:30 p.m. Fri
day. Clark urges everyone in
terested to attend.

Clark at 683-8318 or Tammy Kit
chen at 683-6342.
