A sweet story

From the Associated Press
It all began 50 years ago in a
Massachusetts inn. Ruth Wakefield was
tinkering in her kitchen, trying to invent
a chocolate cookie. She failed-and
created an American obsession.
Wakefield figured she would get a
chocolate cookie if she chopped up a
chocolate bar and mixed the morsels
with "Butter Drop Do" cookie batter.
What came out of her oven instead was
a buttery cookie laced with chocolate
chips.

She tasted what she had done and she
deemed it good. So the Whitman, Mass.,
innkeeper named her invention after
her inn: the Toll House Cookie. She
knew not what she had wrought.
In the half century since Wakefield's
kitchen alchemy, the United States has
grown into a natioin of chocolate chip
cookie monsters.
Market researchers report that three
of every five cookies eaten in this coun-
try are. . . yes, chocolate chip cookies.

used in an energy project by
ngineering students on North Campus.

Class operates solar collectors

By MARK SCHUMACK
There they are, perched on top of the
"penthouse" on North Campus, silently'
absorbing the sun's rays.
Year-round, they use the sunlight
which glistens off their flat surfaces to
heat air and water.
Even in Ann Arbor, where the clouds
almost always outnumber the sun's
rays, the collectors serve as a way to
study the feasibility of such energy-
capturing devices.
THREE COMPLETE and indepen-
dent solar energy systems comprise a
project that was developed by John
Clark, a University professor of
Mechanical engineering.
Two of the systems' collectors are
perched on the "penthouse"-a small
uilding on the George Granger Brown

Laboratory's roof-while a third set of
collectors is positioned several yards
away.
"If you consider the present sub-
sidies, solar energy is virtually com-
petitive with natural gas in Michigan,"
said Clark, referring to tax credits that
are available to persons who install
home solar systems.
Clark started the North Campus solar
systems in 1978 as a research project
for his solar energy classes. The
equipment was donated by manufac-
turers of commercial solar systems and
was installed by his 20 students.
THERE WAS A need to get the
students away from the classroom and
into some "hands-on" experience, said
Clark. He enlisted Bob Burn, then one
of his students and now project
manager, to supervise the installation.

of both air and liquid solar systems.
Today, students participate in what
Clark calls "a legitimate solar ex-
rVerience"
The students run tests and suggest
improvements on the systems.
The most recent addition to the solar
energy project is a system that uses a
refrigerant as its heat-collecting fluid.
The liquid and refrigerant systems heat
water and the air system is used for
heating space.
ALL THREE systems operate on the
same simple principle: a substance
flowing through a panel exposed to the
sun is heated up and then directed
through a system of pipes, pumps, and
controls, where its heat is put into a
useful form.
There are storage containers in-
cluded in the systems that store the
heat for use at times when there is not
enough sunlight. And there is an
auxilary heater' on the liquid system
that takes over during periods of
prolonged sunlessness..
And those periods of prolonged
sunlessness are pretty prolonged here
in Ann Arbor.
Bob Burn says it's worth it. He got in-
volved in the project to "find out about

the feasibility of solar, especially in
Michigan." He plans to build a solar
system for his house:
THE MOST economical use for a
solar system is probably for heating
water, -Burn said. A solar energy
system costing under $2,000-including
hot water tanks, solar panels, controls,
and pumps-could supply 50 per cent of
a household's hot water needs.
Considering an average household's
annual consumption of natural gas for
heating water, then such'a solar set-up
would pay for itself in about 12 years.
And after that, the energy is essen-
tially free.
Clark claims that a space heating
solar system could possibly provide 25
to 40 per cent of a household's annual
heating needs in this part of the state.
CLARK SAID he was concerned
about the lack of information available
to the public on the feasibility of solar
systems.
The North Campus solar project will
eventually be set up to help alleviate
this problem, he said. The project will
serve as a solar information center for
the general public, with students acting
