Do you want to go out for a picnic on a sunny day? How can you take a “green” trip to protect the environment? Walk, bike, take the subway or maybe drive a solar-powered car!

A team of 22 Dutch university students has created a solar-powered car called Stella Vita. Last October, they completed the car’s first road trip. The 2,800-kilometer trip was powered only by the sun.

Stella Vita is a two-passenger car with a kitchen, a sitting area, a bed, a shower and a toilet. There are solar panels (板) on the top of the car. And the solar panels can spread out when the car is parked.

On sunny days, Stella Vita can travel up to 720 kilometers with a top speed of 120 kilometers an hour. The energy it gets from the sun can also be used for other things. People can cook, take a shower and watch TV in the car. On cloudy days, the car still gets 60% to 70% of the energy. It does on sunny days. How can the car keep going at night? Well, it has a large battery (电池) that can store energy. This allows the car to travel up to 600 kilometers at night.

Stella Vita isn’t the Dutch team’s first solar car. Since it was set up ten years ago, the team has created different types of solar cars. The team members are working to introduce this green way of traveling. Let’s hope that in the future, we can all travel “by” the sun!
