Farmers in Kenya soon will benefit from a new, hand-crankable mill designed by
a team of senior engineering students at Calvin College.

Team "Sow What?" spent this entire school year researching, planning,
designing and building a small mill that farmers in Kenya, and other countries,
can use to increase their productivity in harvesting amaranth, a broadleaf
plant that grows to between two and eight feet tall and has a very high
nutritional value.

The students - mechanical engineering students Brian Katerberg (Kettering,
OH), Kristin De Groot (Tulare, CA), Dan Schrik (Brantford, ON) and Andy Vander
Moren (Hanford, CA) - are working with volunteers from Hillcrest Christian
Reformed Church and the Christian Reformed World Relief Committee (CRWRC) on
the project.

The amaranth seed is becoming a versatile cash crop in eastern Africa with the
seeds of the plant sold as a health food in the United States. In fact,
amaranth sells for three times as much as corn on the current market, making it
a good source of income for underprivileged families.

The mills currently being used to thresh and winnow amaranth seed in Kenya are
rundown and inefficient. The Calvin team designed a mill that is simple and
efficient.

"We wanted to do something that was third-world oriented, something that was
helping people rather than something that was fun for the moment without a
purpose," says Katerberg, whose mission trips to Malaysia and Thailand have
made him eager to use his engineering degree in third-world development.

The mill developed by the team is a small, hand-cranked model, which utilizes
a fan to blow the chaff free of the amaranth seed. The team intentionally
designed a small mill to make it easy to ship the machine through customs.

Bob Beute, the director of ministries for Hillcrest CRC, likes the student's
design for its simplicity and effectiveness.

"I think the prototype machine is absolutely beautiful," he says. "When I see
the size - it's lightweight - when I see that it threshes and cleans, it's just
astounding what those students have done."

Beute says that Hillcrest volunteers have been working on an amaranth project
in Kenya for four years now and formerly bought used mills at antique stores
and auctions before refurbishing them for use by amaranth growers. But those
old models didn't winnow the amaranth seed.

The hand-powered nature of the mill is an appropriate touch as well says
Beute.

"Everything we do there has to be hand-powered" he says. "They have an
absolute abundance of labor there."

Team "Sow What?" already has tested the prototype mill with amaranth grown by
Hillcrest members.

The next step is to begin producing the mill and shipping it to Kenya. The
plan is to send it as a kit along with pictorial instructions being tailored by
the student design team to Kenyan reading abilities.

Beute notes that the list of countries who want the mills is growing and now
includes amaranth projects in Uganda, Mexico and Belize.

Calvin professor Steve VanderLeest says the "Sow What?" project is a good
example of what Calvin looks for in its students' senior design efforts.

"It's a good project in a number of ways," he says. "We like seeing students
work with real-world groups because they have to work within constraints. Doing
that forces them to be creative in ways they normally wouldn't when they design
on paper. It is certainly one of the ways we like to see our teams use their
engineering and put it in practice with their faith."

Other projects for 2004-2005 include an automatic deterrent system to help
protect gardens from animals that raid them, a machine to remove air from a
pre-assembled shock and then fill it with light-weight shock oil (for race car
applications) and the designing of a building addition for Dutton Christian
School.

NOTE TO MEDIA: Katzenberg, DeGroot, Shirk and Vander Moren will formally
present the mill on May 7, 2005 at Calvin's 21st annual Senior Design Projects
Night. An open house viewing of all the senior design projects will begin the
event, followed by dinner and the student presentations.
