From VOA Learning English, this is the Technology Report.Students at the University of Johannesburg in South Africa are building solar-powered cars and racing them in competitions.The University is training the students to become experts in different types of energy.Their 300-kilogram solar-powered car is traveling at more than 100 kilometers per hour through the South African countryside, and it is using less electric power than a small kitchen appliance.The young engineers who built the car drove it in the Solar Challenge, a national racing competition for cars that use alternative energy.Kegan Smith is the former manager of the project and a lecturer at the University of Johannesburg.He says the university wants the students to learn about green energies using realistic examples."With what we do at the moment in fossil fuels, if we continue like this, there is not going to be a future.And if we do this kind of alternative energy, the cars are one application. But the nice thing with the cars it that it's a mindset change.If you can start shaping students' mind now, it's going to change the mindset of people in general. How do you use your lights? How do you use your electricity?" explained Smith.When he was a student in 2010, Mr Smith was part of a group that built a hybrid alternative-energy powered car.
