At present, solar vehicles have become the new direction of the development of green energy vehicles in the future. Scientists and researchers all over the world are also trying to make solar cars that can be widely promoted. Sasha is the president of the Solar Car Club of Stanford University. He believes that it is not practical to bring solar cars to the market, but solar cars are attractive in appearance and advanced in concept, and they can still be loved by many people. Especially solar racing, its cool appearance and outstanding functions have attracted the attention of many researchers.
It is reported that solar racing cars are generally made of carbon fiber, with a three-wheeled single suspension design, and the body is covered with solar cells for collecting energy. However, the high temperature generated in the process of solar energy collection has always been one of the difficult problems to solve. Sasha said: "If the car is driving, the temperature of the surrounding air will not be very high because of the exhaust port in the car, but once the car stops, the temperature will rise sharply. We have recorded that the temperature inside the car reaches 130 degrees Celsius. "
The solar team made by Stanford University in the United States was established in 1986, and the team members are all students.
They named their solar car Apogee and used it to participate in the World Solar Challenge held in Australia. This year1October 25th 10, the 10th global solar Racing Challenge was held as scheduled. By then, teams from all over the world will not only face fierce competition, but also the difficult road section of 1800 km will pose a great test for the racing cars of each team. At present, the most powerful team is the solar racing car designed by Delft University of Technology in the Netherlands, which has won the championship four times. Sasha said: "In all 42 racing teams, Apogee will eventually rank between the fourth and eighth." .
It is reported that Stanford University began to develop Apogee two years ago, and has invested nearly 90,000 US dollars so far, part of which comes from off-campus fundraising. Compared with Apogee, the Eleanor car designed by MIT is more expensive, reaching nearly $250,000, but the top speed of Eleanor is also 90 mph (about 145 km/h). The weight of the vehicle is only 170kg, and the relevant design has been optimized in aerodynamics, friction resistance, power control and other aspects. Its special braking system can even convert kinetic energy into electric energy when braking.
