`We are in need of petroleum. The best way to way to save the resource is to minimize the use .One alternative is to find a fuel free car. Keeping this in mind Honda motor recently started the production of FCX Clarity, the world’s first hydrogen powered fuel car. The company will produce just 200 of the futuristic vehicle over the next three years. But the manufacturer will increase the production as hydrogen filling stations become more common. Fuel-cell vehicles work by combining oxygen and hydrogen to make electricity. The by products will be water and heat. These cars have more advantage than electric cars as they take hours to recharge. We can drive the car for 450 kilometer on a tank. It is equal to gasoline car. The fuel cell vehicles have been a gamble for Honda and Toyota. The difference between the two rivals is the size of its fuel cell. In FCX Clarity the cells can be fitted in a box shaped unit, which is the size of a desktop PC. It weighs around 68 kilograms. The car can reach 0 to 95 kilometer per hour in less than nine seconds. The top speed of the car is 160 kilometer per hour. The big hurdle to mass production is the lack of hydrogen filling stations. The design of the car is sleek and elegant

The use of satellite and fiber optics in recent years has made radio communication even more widespread with increasing emphasis on computer and other data communication. Now in this post we are going to see about basic requirements of radio communication. The requirements are transmitter to generate a high frequency carrier, a microphone to impress the intelligence upon the frequency carrier, transmitting antenna to radiate the high frequency carrier with intelligence impressed on it into free space, a receiving antenna to intercept a portion of the radiated electromagnetic waves travelling in free space, a receiver to select the desired wave to magnify the intercepted radio waves and to deselect the message and finally a loudspeaker to convert the detected AF electrical waves into sound waves and thus to reproduce back the original intelligence transmitted from the transmitting end.
