Solar Car meets Aptera in D.C.


















Two members of the UK Solar Car Team had the opportunity to meet with officials from Aptera Motors during the EGR599: Engineering Leadership trip to Washington, D.C.

Anthony Robertson and Nick Such conversed with CEO Paul Wilbur and Senior Engineer Sean Touhy as the Aptera 2e was displayed on Capitol Hill. The Aptera 2e is an electric vechicle, capable of 100 miles per charge, at an efficiency equivalent of 300+ miles per gallon. Of all production vehicles, it is the most similar to UK's Solar Car.

Aptera was in Washington with a congressman from their home state of California to lobby for its piece of the DOE's $25 billion in funding for domestic production of high-efficiency vehicles. While the Federal Government prepares to distribute this funding to other automakers, Aptera's application was initially rejected due to the fact that it has 3 wheels, instead of the conventional 4. This article from Wired.com further explains their situation.

Aptera is one of the frontrunners for the Automotive X-Prize.

Solar Car Team member Sam Nicaise was also on the D.C. trip, and had the opportunity to meet with Congressman Ben Chandler at the same time.

Foam arrives from Lowe's

We learned the effect of compounding overestimation as 100 sheets of XEPS (Styrofoam) arrived today, filling up most of the garage's main room. This should provide us with plenty of foam for manufacturing the shell and fairings for Gato del Sol IV.

This foam will be used to create a male mold, also known as a plug, in the shape of Gato 4's shell. This will be accomplished in two steps. First, we will cut and glue the 2 inch sections of foam together to form the rough shape of the car. Second, we will use a large 5-axis CNC to precisely mill the shape of the car from this block using our 3D CAD model as the reference.

Thanks to Lowe's of N.E. Lexington and their price-match guarantee for helping us to move forward with our new shell-manufacturing process!

Versailles Family Science Day

The Solar Car Team celebrated Pi day by showing off Gato del Sol III at the Versailles Family Science Day at Huntertown Elementary.

The purpose of our attendance at the event was to provide positive role models in the STEM fields (Science Technology Engineering and Math). We talked to over 100 students and their families about our trip from Texas to Canada and explained how a solar-powered car works. UK's SWE chapter was also on hand with a cool demonstration of paper rocket propulsion.

Anthony even got to fulfill his life-long dream of making an announcement over the intercom!

Thanks to Versailles resident and Lexmark engineer Glenn Edelen and his family for coordinating the inaugural event, and even adopting a solar cell!

Field trip to the solar car!

On Tuesday, the UK Solar Car Team welcomed 36 middle school science students from Sts. Peter and Paul school in downtown Lexington. The students braved the wet, not-quite-sunny weather to learn more about alternative energy and take a tour of the Solar Car garage.

Part of our team's mission is to inform the community about the benefits of solar power and energy efficiency. We are especially interested in inspiring the next generation of engineers and scientists.

Back from the race, back to work.

The University of Kentucky Solar Car Team has made some great progress since returning from the 2008 North American Solar Challenge. Initially focusing on recruiting efforts, we participated in several K-Week activities at the start of the Fall semester, including leading a parade through campus. In addition to great publicity for the car and the team, we have attracted over 30 new team members to join our efforts.

Gato del Sol III leading a parade.


We have had several opportunities to share our car with the public, including:
  • Karl Shannon's 8th Annual Cruisin' for St. Jude car show
  • Engineering Homecoming weekend
  • Big Blue Goes Green Sustainability Fair
  • Bluegrass Green Expo
Public officials from the Commonwealth were curious about Kentucky's only solar-powered car, as well. During BBGG, Lexington's Mayor Newberry got to check out Gato 3, and Governor Steve Beshear took our car for a spin during his visit to campus.

The team is currently in the design phase for our next car, Gato del Sol IV. We have over 40 students working hard on eight different project teams. This includes two Mechanical Engineering Capstone Design (ME411/412) groups. We also have increasingly strong faculty support from our advisors, Dr. Scott Stephens and Dr. Vijay Singh, to help review our design decisions.

With the support of the College of Engineering we have obtained new Gallium Arsenide solar cells from EMCORE. These cells are approximately 26% efficient, compared to the 18-20% efficiency for our previous cells. This is a significant investment in the future of UK Solar Raycing, because it allows us to generate more power from a smaller, lighter car.


Our new solar cells!


The plan for Gato 4 is to participate in the 2010 North American Solar Challenge (NASC). We are also conducting a feasibility study for participation in the 2009 World Solar Challenge (WSC). This race, which will take place in Australia in October of 2009, is a high-speed sprint across the continent, whereas the NASC relies more on weather and energy strategy. This would be UK's first attempt to compete in the WSC.

We are always looking for new sponsors; without their support, we would not be able to participate in this great learning experience. Gato del Sol III was made possible by:
  • Belcan and Ralph G. Anderson
  • Hydro Aluminum
  • Stone Farm
  • Sunpower
  • Toyota Motor Engineering and Manufacturing, North America
  • UK College of Engineering
  • UPS
We are currently in talks with a few new financial, process, and material sponsors. This will help us with composite materials, shell molds, chassis and suspension parts, and electronic components.In addition, our Adopt-A-Cell program has returned. This allows anyone to support the UK Solar Car Team through a $50 donation, which pays for one of our 2000 GaAs solar cells.

If you are interested in supporting the UK Solar Car Team, please contact us at: solarcar@engr.uky.edu

That's all for now. From our team to yours, we hope you have a Happy Thanksgiving!

Race wrap-up!

Well in my last post I promised a quick update on the events surrounding the last day of the race, but it just seemed that my lack of sleep had finally caught up with me, for that is all I did whenever I had free time at the hotel. Well now we’re on the road again, halfway through Wisconsin on our way back to Lexington. But now, I’m just going to recap the events from last Tuesday on.

Being the last day of the race leaving from Medicine Hat, the whole team was very excited to get started on the last day of our long journey. It was a relatively short leg, being less than 200 miles long, but there were some factors that made it seem quite longer. Early into our last leg from Medicine Hat, the rear window of our lead vehicle just shattered. Being one of the two people in the back seat, it gave us quite a start. We supposed it could have been caused by the passing 18-wheeler, but we didn’t care to bother pondering that too much, we just pushed all the broken glass into the trunk and got on our merry way.

Being in the back seat without a rear window did have its benefits, such as an unobstructed view of the solar car so that I can take this nice picture! Solar car meets oil derrick…

We then swapped out Scott for my turn to drive. Figuring that Nick got the starting line, Scott got the Canadian border, it seemed reasonably fair for me to take the finish line. But before I got in, I made sure that I brought my camera to take some action shots while I still had a chance.


Another troublesome part of our drive was the strong headwind that we had to plow through. To put the importance of aerodynamics of a solar car into perspective, we were driving around 30 mph in the middle of a blazing noon sun. Without the wind, we would either be charging our battery or we could choose to go faster, but on this day, we were actually wasting a significant amount of our battery power.

After dealing with that trouble, new problems lay ahead of us. We were approaching the edge of the city of Calgary, under an overcast sky, in the middle of rush hour, and we had less than 45 minutes to cross the finish line. We had a completely drained battery pack from the day’s drive, so we had no other choice but to trailer the last 20 miles. Unpacking the car right at the edge of the finish line, we were able to cross the line with just three minutes left to spare! Having to put the car into the trailer for the last 20 miles was certainly a damper on our spirits, we were really hoping to be able to make it, but crossing the finish line completely alleviated those feelings. We were done!

On Wednesday, we attended the awards ceremony that was hosted by the University of Calgary and the Calgary Zoo. We got a nice lunch, and all the teams got a chance to trade each other’s team shirts. I got two Calgary shirts and a Michigan shirt, a very good haul! Then we got a chance to explore the zoo, which, of course, was a ton of fun!

But now, like I said, we are in Wisconsin, about 100 miles away from Madison, our intended stop tonight. We have been driving nonstop since 1:00 pm yesterday. We intended on stopping for the night in North Dakota, but then we learned the hard way that there are not many motels where we drove though. So we’ve been on a nap/drive rotation that has worked pretty well, but such driving is pretty taxing and we don’t want to do that for the full 32 hours it takes to get from Calgary to Lexington. We hope to get back on the road early tomorrow morning so that we can get back in the early afternoon.
