m any other power supply.
There is one more advantage of solar power: not only it is unlimited, but also its use does not pollute the environment. That is why it is very important to develop devices which make it possible to transform solar power into mechanical or electric forms of power.

Power supply - источник энергии
Appliances - техника, прибор

Sun Powers Cars.
1) How do solar-powered cars differ from gas-powered cars? (Solar-powered cars use solar power, they are lighter, their tires are as thin as bicycle tires. )
2) Were the solar cars lighter than gas-powered cars? (Yes, they were. ) Why had they to be light? (The cars had to be light because their motors didnt have as much power as cars with gas-powered motors. )
3) What amount of energy did solar cars use? (The solar cars used the amount of energy needed to run a hair dryer. )
4) Will people be able to buy solar cars soon? (Most scientists say no. )
Sun Powers Cars.
Each day, millions of people across the world fill their cars with gas to make them move. But can you imagine running a car on just a tankful of sunshine? Thats what some students did this past summer in the U. S.
The students built cars for an unusual race called "Sunrayce USA. " The students had to drive their cars from Florida to Michigan, more than 1,600 miles, in the fastest time. The only power their cars used was solar power, or energy from the sun.
The students solar-powered cars were different from any gas-powered car on the road today. Heres how.
The outside of the solar cars was covered with rows of dark shiny panels made of special materials. These panels caught the suns rays and turned sunshine into electricity that
