Tokai University's Tokai Challenger raced through the deserts of Australia.[vol2-0 min 17 sec]

These 4 video reports cover the story - from development of the solar car all the way through to the finish line - of a group of students who took part in the very tough solar car race that took them across Australia. The "Bridgestone World Solar Challenge 2013" is one of the world's largest solar car races, and the Tokai University Challenge Center Light Power Project Solar Car Team entered this race. Panasonic has offered the team technological support since 2011. This year, the team faced many problems such as major changes in the racecar criteria, problems during the qualifying, and adverse weather to become one of the 10 teams of the 22 that finished the race. Please take a look at their daring adventure.

The members' expectations rose with the delivery of the HIT solar cells. [4 min 20 sec]

July 19, 2013, six weeks before the race. The Tokai University team received the coveted, new HIT solar modules. Not only did they boast 0.5% better conversion efficiency than the last model, they were also very light. Students' expectations rose. This year, they had to adjust to new criteria, such as making the solar cars with 4 wheels rather than 3. The members put their heads together to develop the optimal solar car.

The test run was held at the Ogata Solar Sports Line (Akita), which has a very long straight stretch. [3 min 28 sec]

August 24, 2013. In preparation for the actual race, the first test run was held at the Ogata Solar Sports Line in Akita prefecture. Major changes to the criteria were made this year, such as the length and width of the car and number of wheels, in addition to securing space in front of the cockpit. After the racecar was built, the drivers put it to the test. They were nervous of course, because it was the first test run. So how did it turn out? Please watch and see for yourself. This video also features scenes from the press conference at which they announced their entry.

Early morning. As soon as the sun appears on the horizon, the Tokai Challenger began to charge.[5 min 25 sec]

Finally, the first day of the race. The qualifying race was held in Darwin, where it was all to start, to determine the poll positions. But an unexpected accident happens during this race. Because it won the last time, the Tokai Challenger started the qualifying race in last place. Due to the sand that spread across the road from the other cars that had gone ahead, the Tokai Challenger's tires slipped, and it spun out. As a result, the team had to start in the 20th place out of 22. Two days into the race, it had climbed to second place, but was unable to close the gap with the top team. This is when the team decides to take a great risk. Aware that it will eat up more battery power, they changed the settings of the motor to enable it to go faster. Please watch them tear exhilaratingly across Australia as they encountered numerous challenges such as a tornado and the endless stretch of desert.

Vol.4 The Race (Final race day 5 to the finish line) - Bridgestone World Solar Challenge 2013 -

review

The Tokai University team finished in second place after having raced 3,000 km in adverse conditions. [3 min 07 sec]

Day 5, the final day of the race. After their daring effort to catch up to the team in first place, little battery power remained. Unfortunately, the overcast sky was getting in the way of solar power generation, they were still 25 minutes behind the top team, and there was only 200 km left to the finish. What made it worse, 1 hour and 10 minutes from the start, it began to rain and the headwind together with the rain forced the Tokai Challenger to a stop. The team members rushed over to face the car's body towards what little sun there was coming through the clouds to generate as much energy as possible. Meanwhile the team in third place was closing in. Then, as though their prayers had been answered, the Tokai Challenger slowly started to moving again! Please watch the moving finale.
