  Free energy is everywhere around us.There are many ways to make and collect energy from various sources like sun, wind and water.People also realize that everyday stuff can be a source of energy too.For example, riding a bike, running or just walking, etc.We simply have to change our way of thinking if we want to change the world.

  So comes the idea of solar roadways.Are they the road of future? Why use roads just for driving and collecting tolls(过路费)? Why don’t we use them for collecting energy?

  The US Department of Transportation recently awarded $100,000 to Solar Roadways to build the first ever Solar Road Panel.So how do these future roads work?

  The Solar Road Panels will contain embedded(嵌入的)LEDs which “paint” the road lines from beneath to provide safer nighttime driving as well as to give drivers instant instructions such as detour(绕行)ahead.The road will be able to sense wildlife on the road and can warn drivers to “slow down”.There will also be embedded heating elements in the surface to prevent snow and ice buildup, providing safer winter driving.

  Replacing asphalt(沥青)roads and parking lots with Solar Roadway Panels will be a major step toward stopping climate change.Fully electric vehicles will be able to recharge along the roadway and in parking lots, finally making electric cars practical for long trips.

  We just can’t wait to see more of these roads all over the world in the near future.

  Modcm inventions have speeded up people's lives amazingly.Motor-cars cover a bundred miles in little more than an hour.Aireraft cross the world a day, while computers operate at lightning speed.Indeed, this love of speed seems never-ending.Every ycar motor-cars are produced which go even faster each new computer boasts(吹嘘)of saving preeious seconds in handling tasks.

  All this saves timc, but at a prick.When we lose or gain half a day in speeding aeross the world in an airplane, our bodies tell us so.We get the uncomfoerable feeling known as jet-lag; our bodies feel tlru they have been left bebind in anot ar nine zoors Again pending too long at compulers resul's in painti ninrts and fingers.Mobile phones also to dange according to some seientists; too much uss may thesmit h bul radiation into our brains, a we do not like to think about.

  Howave, what do we do with the time we have saved?Certainly not or so it seems.We are so accustomed to constant activity that we find it difficult to sit and do nothing, or even just one thing at a time.Pcrhaps the days are long gone when we might listen quietly to a story on the radio, letting imavination take us into another world.

  There was a time when some people's lives were devotcd simply to the cultivation of the land or the eare of eattle.No multi-tasking there; their lives wenl on at a much gentler pace, and in a familiar pattern.There is much that we might envy about a way of life like this.Yet before we do so, we must think of the hard tasks our ancestors faeed;:they farmed with bare hands, often lived close to hunger, and had to fashion tools from wood and stone.Modem machinery has freed peope fre that primitive existcnee.
