The idea of a solar-powered car is an interesting one. Although plans for mass-producing such a car is slow-going, there are huge hopes for the future in manufacturing such a vehicle. How does a solar-powered car work? Solar-powered cars harness energy from the sun, convert that energy into electricity, then uses that electricity to power the battery that runs the car. A more in-depth explanation can be found here: reference.
Advantages to such a car can be anywhere from requiring less time to go to the gas station to fill up a tank to having a vehicle that is greener for its environment. To be rid of a trip to the gas station can save the population a few headaches here and there. Additionally, that may possibly lead to a fuller wallet depending on the implementation of such a machine.
