This summer has been a very
productive time for Team
PrISUm's Mechanical Team. We
have been working diligently on
the construction of the vehicle
body molds and wrapping up the
designs of the mechanical systems.
In recent weeks, we have been
doing quite a bit of traveling to
acquire products and make use of
donated services. The Boeing

Company and DARPA in St.
Louis were very gracious and
gave four Team PrISUm members a tour of the Phantom Works
before helping us load carbon fiber into our truck. We saw lots of
interesting things and now we understand even more about how
this multidisciplinary project applies to real life problems in industry.
During the last week in July,
we had the pleasure of working
with a great company, and a great
group of individuals. The generous folks from Remmele Engineering, Inc. (REI) volunteered
their machining services to create
the aerodynamic body molds for
PrISUm Odyssey.
In the coming months, our final drawings will be coming to
life, and the mock up of the chassis will begin to have parts
mounted to it. This fall we will
be welcoming a new class of

Note
By Nick Mohr
Director, Team
PrISUm
As this summer begins to draw to
a close and as people begin to return
to Ames for the new school year, we
can’’t help but to reflect on a very
productive summer.
Thanks to all of our very generous sponsors, our fundraising has
topped the $350,000 mark, which
brings our goal for the next year to
about $200,000. I am looking forward to working with all of you to
make that happen.
We have been very fortunate over
the last few months to have secured
a lot of help from some very generous donors. You have read earlier in
this issue about the team’’s recent
trips to Boeing in St. Louis and REI
in Minnesota. I would like to extend
a special thanks to these corporations, and others, who have been so
hospitable and generous to Team
PrISUm.
This summer, the team has made
great strides in finalizing the design
for PrISUm Odyssey. Right now,
we are planning to hold a design review on September 16 at Iowa State
to announce the technical design
considerations for Odyssey. If you
would like to attend this event,
please feel free to contact us at the
Team PrISUm administrative office.
Also, much like the revision to
the style of The Sundial, Team
PrISUm’’s website has undergone
some substantial changes as well. I
would encourage each of you to visit
the new site and read about our ongoing progress. You will also see on
the new web site the opportunity to
sign up for an e-mail newsletter,
where you can get more timely updates and other interesting information.
Nick is from Bettendorf, Iowa, and is
majoring in Mechanical Engineering.

Strategy Team Update
By Mike Dorman
Director of Strategy Systems
How many miles per gallon does your car get? 12? 15? 20,
maybe? Everyone knows that you save money when your car gets
good gas mileage, because you don't have to fill up as often.
In solar car racing, we're not concerned with saving gas money
(sunlight is free, after all). But, we are interested in conserving the
energy stored in the solar car's batteries. Instead of 12 to 15 gallons
of gas like your car, we have 35 to 45 Amp-hours of power when our
"tank" is full.
The Strategy Team is tasked with investigating the components of
the solar car, gathering information about the race route, and analyzing weather forecasts in order to develop an optimal racing strategy
for our team. We have to find answers for difficult questions like,
"How fast should we drive today?" "Will we have good sunlight later
this afternoon?" and "How much power will we get from the sun in
the morning?"
Fortunately, we are able to take advantage of computer resources
to help us answer those questions. We're beginning the development
of a new simulator program that will accurately predict how PrISUm
Odyssey will perform throughout the race route. Those simulations
combined with real-time telemetry data from the Electrical Team and
weather information from the R.Ob.I.N. network will enable us to
drive as effectively as possible (and hopefully win the race!)
We still need some help, however. The computer resources we
have are becoming outdated, and we are turning to corporate sponsors
for equipment donations and support. Recently, Street Wizard donated their mapping development software that will be put to use in
our navigation system.
Mike is from Cedar Rapids, Iowa, and
is majoring in Computer Engineering.
The current American Solar Challenge Route will follow old Route 66.
This will take solar cars through mountains and deserts.
What are the vehicles of the future really going to be like?
Dwight Brown
Director of Systems Integration
This summer I have taken on
the challenge of directing the design and construction of Odyssey
while working as a full-time intern at General Motors in Detroit.
Here in Detroit, I have had a
wonderful opportunity to see
what automotive manufacturers
around the globe have up their
sleeves for the 21st Century.
Over the years, Team PrISUm
has often been asked if solar cars
will show up in garages sometime
down the road. Here is your answer:
Yes and No.
If you are happy, you can stop
here. If you would like to know
more, keep reading.
The vehicles of the future will
be packed with efficient and regenerative power-trains, some of
which may attain their energy
from the sun through photovoltaics. Many of the vehicles now
being designed by major manufacturers incorporate many different types of systems to propel vehicles down the road. Amazing

Solar Array Research and Development Update
By Brennan Downes
Director of Solar Array R/D
This summer has been a productive one. The solar array team
has determined the type of solar
cell that we are going to use for
PrISUm Odyssey and is working
on the several details so we can
have the modules on the array
ready for encapsulation by the
end of fall. There are many
planned changes in the design of
Odyssey’’s array to make it easier
to build and repair. We have already sized the array and have
worked with the mechanical and
electrical teams to ensure that the
array will be as efficient as possible. Many aspects of the array
need to be taken into considera-
tion for reasons other than the
collection of the sun’’s energy.
The configuration in which the
array collects energy is dependent
on the type of maximum power
point trackers and the batteries
that we are going to use in the
car. In the same respect, the aerodynamics of the car are affected
by how much the array interrupts
airflow around the car. A poorly
designed array could actually decrease the car’’s performance by
using power it has collected to
overcome the air resistances it develops on the surface of the vehicle. To help decrease the drag
and the increase the overall per-
formance of the array, we are
consulting professional solar array designers to ensure that we
will be able to compete at the
highest level in this race. We are
excited for the end of summer
(really we are!) so that we can regroup back in Ames and continue
our progress with the assistance
of those students who have been
away for the summer and of those
that are new to the team.
Brennan is from Wheaton, Illinois,
and is majoring in Electrical Engineering.

Recently, John Burns had the
opportunity to join three other solar car teams on the American Solar Challenge trial run. Students
from MIT, University of Missouri-Columbia, and University of
Waterloo operated the solar car
from the Massachusetts Institute
of Technology, while the RoseHulman Institute of Technology
(RHIT) solar car (Solar Phantom
V) was operated by a composite
team from RHIT, Iowa State University, Ohio State University,
and the University of MissouriRolla. They traveled from Chicago, Illinois to Los Angeles,
California over the course of two
weeks.
After participating in this trial
run we strengthened our friendships with the other teams and
saw the route for the upcoming
American Solar Challenge 2001.
Back in the garage, we are currently working on prototyping our
designs for Odyssey’’s most critical electrical components, such as
battery monitoring and propulsion
control. We are also working
closely with the mechanical team
and drivers to iron out the details
of the driver interface. Our latest
efforts include implementing failure-tolerant systems and redundancy into our designs.
Rose Hulman Institute of Technology brought Solar Phantom V
along during the ASC trial run.
R.Ob.I.N. Team Update
By Matthew Nelson
Director of Team R.Ob.I.N.
Greetings from Team
R.Ob.I.N! As the long summer
days have been progressing, we
have been diligently working on
the R.Ob.I.N. system. Team R.
Ob.I.N. will handle all
communication matters for the
team. We are excited about this,
and we are looking forward to
starting a new tradition at Team
PrISUm.
In other news, a meeting was
held July 12th so that we could
update everyone on what has

happened so far this summer. At
the meeting we discussed future
plans for the data side of
R.Ob.I.N. using TCP/IP and
packet radio. TCP/IP is the type
of computer protocol that we will
be using to transfer data. We
have learned a lot about TCP/IP,
some built-in support that Linux
has for TCP/IP, and about the
implementation of the network.
Linux will be the operating
system that we will be using. We
want to have a two station TCP/IP
network up and running by the
end of the summer.
July/August 2000
We also have received a
second pneumatic tower from
KCCI——TV in Des Moines to be
used to elevate the antennas.
These towers should work very
well for our application. A
second repeater system will be
worked on into the fall semester,
and we will be programming the
controller. We also need to finish
testing the system and build a
suitable casing for the receiver
and exciter units. With this
complete, the only components
we need will be duplexers for the
repeater, a 440 radio for the link,
and dual band antennas. Once we
have these, we will be able to
have two repeater systems that
can be linked to each other to
extend the range. From Team
R.Ob.I.N., thank you for your
support, without you, we would
never get the chance to fly.

Outreach Update
By Erin Isvik
Outreach Coordinator
We've had many calls come
through and I think that is
GREAT! I love to hear from folks
wanting to see the car and to learn
about the team. On August 5th we
went to Waverly to display Phoenix at the Iowa Renewable Energy
Expo. The students that attended
the event said that it was great to
talk to the different vendors about
their products and share information about Team PrISUm.
We will be in the Storm Lake
area on September 23 for the Enron Windfest and we would love to
see everyone there. We will also
be at the College of Engineering
Tailgater preceding the UNLV
football game on September 9.
We love getting a chance to talk
with our supporters, so if you can,
stop by and say 'hi'.
