Spencer Composites Corporation
supported South Dakota School of
Mines and Technology in both
Sunrayce 95 and Sunrayce 97. The
fabrication of "Dakota Sun" took place
at SCC.

Zachary Spencer, now a Spencer
Composites Project Engineer, was
the Composites Lead Engineer for the
95 car, the Head Mechanical
Engineer in 1997, and instrumental in
the development of a filament wound
composite car for Sunrayce 97. Zack
was a Sunrayce Team Member while
a Student studying mechanical
engineering at SDSM&T from 1994 to
1998.

The biennial Sunrayce program offers university teams the
opportunity to build solar-powered vehicles and then compete
against one another.

Sixty-five college and university teams registered for Sunrayce
95. All teams must participate in the Qualifier. Each solar car
must drive a minimum of 50 miles around a closed course at an
average speed of 25 mph in order to qualify. The Qualifier
reduced the field of 55 registered teams in Sunrayce 97 to 40
participating entries for the actual event. Pole position is
determined by the team with the greatest number of miles
completed at a minimum speed of 25 mph during the qualifiers.

SDSM&T made its first appearance to solar car racing and had a
successful year in Sunrayce 95. The Solar Rolar finished in 16th
place, the highest placing "rookie" team. Two awards were given
to its Solar Motion Team, "The Best Use of Technology" and
"The Humanitarian Award". South Dakota School of Mines &
Technology's 97 entry was the Dakota Sun. The car received
the "Best Design" award. It reached speeds up
70 mph and weighed only 900 pounds.
