Solar cars aren't so familiar to us as solar water heaters on top of buildings. However, they're already in races. Solar-powered cars, to be exact, are powered by solar cells that convert (转换) solar energy into electricity. Every few years a collection of strange-looking low black vehicles gather in Australia for the World Solar Challenge, a solar-powered car race covering 3,020 kilometer from Darwin to Adelaide. Various teams from around the world will join in the race, most of which are sponsored (赞助) by universities and companies. The most successful team in the past decade has been a Dutch team from Delft University. Another team, consisting of Hawaiian high school students, was the subject of a famous film, Race the Sun.
The solar-powered cars are allowed to drive through the Outback, the remote and arid areas in the centre of the country in the World Solar Challenge. averaging over 90 km/hr. The purpose of the race is to promote the development of solar-powered cars. This aim has been more than realized, as solar technology has improved so much since the first race in 1987 that the cars can now go well over the legal speed limits. In fact, new rules have been introduced to reduce speeds.
The new aim for solar powered vehicles makers is to develop cars larger and more comfortable than the racing models. In December, Swiss teacher Louis Palmer completed a 17-month, 52,000 km trip around the world in a "solar taxi". His three-wheeled car pulled a trailer with solar cells and batteries. Palmer's solar car can travel 300 km on a single charge, and reach the speed of 90 km/hr. The prototype (原型) was expensive but he hopes that, if mass produced, it would sell for around 10,000 Euros.

Now come some money-saving ideas from a web forum (论坛), which may help you save a penny in the UK.
Nancy: Many people nowadays seem to buy clothes, wear then a couple of times and then give them to charity shops so that's where I do my shopping. You can pet some cheap but really good stuff and you know you’re your money is helping other people so it's a win-win situation in my opinion.
Ailsa: I'm a student and I have a part time job during term time and then work full-time during the holidays. You really can find some good bargains at the end of the day when a lot of food is reduced because it has reached its sell-by date (保质期). It's amazing how much you can save that way.
Gary: I must admit I don't think much about how or where I shop but I try to save money on electricity and gas in the house. Instead of turning up the temperature I put on another sweater and I close the doors. I encourage roommates to turn off the lights when they leave and we don't leave the TV or computer on standby (待机) as that uses up unnecessary energy.
Matthew: I've just moved to the UK. Someone told me about the "freecycle" scheme and I've managed to get almost everything without spending any money. Basically, you advertise what you don't need on its website for someone to collect it. No one makes any money so it really is a good exchange.

A.Using the student card for discounts. B.Buying things at lower prices.
C.Getting food from the charity. D.Saving money by earning
