An anti-lock braking system (ABS, from German: Antiblockiersystem) is a safety system that allows the wheels on a motor vehicle to continue interacting tractively with the road surface as directed by driver steering inputs while braking, preventing the wheels from locking up (that is, ceasing rotation) and therefore avoiding skidding. An ABS generally offers improved vehicle control and decreases stopping distances on dry and slippery surfaces for many drivers; however, on loose surfaces like gravel or snow-covered pavement, an ABS can significantly increase braking distance, although still improving vehicle control. Stopping a car in a hurry on a slippery road can be very challenging. Anti-lock braking systems (ABS) take a lot of the challenge out of this sometimes nerve-wracking event. In fact, on slippery surfaces, even professional drivers can't stop as quickly without ABS as an average driver can with ABS. The theory behind anti-lock brakes is simple. A skidding wheel (where

The fuel cell vehicle (FCV) is the nearest thing yet to an "ultimate eco-car" that offers solutions to energy and emissions issues. FCVs are powered by fuel cells, which generate electricity from hydrogen, which is not only environmentally friendly and highly energy-efficient, but can also be produced using a variety of readily available raw materials. Thanks to these characteristics, fuel cell vehicles are ideal for achieving sustainable mobility. Therefore, Toyota is striving to make this vehicle technology widely available as soon as possible. Successful startup: -30° Celsius Extended cruising range: 830km (JC08 mode) without refueling At a steady cruising speed, the motor is powered by energy from the fuel cell. When more power is needed, for example during sudden acceleration, the battery supplements the fuel cell’s output. Conversely, at low speeds when less power is required, the vehicle runs on battery power alone. During deceleration the motor functions as an ele

This is the list of biggest cities in the World.I like big cities. I also like interesting facts, geography, and statistics. Occasionally, I wondered what the biggest cities in the world are. I found the following statistics online, from Thomas Brinkhoff, Principal Agglomerations and Cities of the World. Web: www.citypopulation.de. Tokyo Mexico City İstanbul Urban Area / City Name Country Estimated population (in millions) 1. Tokyo Japan 34.2 2. Mexico City Mexico 22.8 3. Seoul South Korea 22.3 4. New York USA 21.9 5.

Chesapeake Bay Bridge-Tunnel The  Chesapeake Bay Bridge-Tunnel ( CBBT )  is a 23 mile long bridge and tunnel system that connects southeastern Virginia with Delmarva Peninsula in the United States. The bridge connects the following independent cities Virginia Beach, and Norfolk, Virginia to Cape Charles in Northampton County along the eastern shore of Virginia. The Chesapeake Bay Bridge-Tunnel uses a combo of tunnels and bridges over two separated shipping channels using four artificial islands built in the bay as portals. The bridge-tunnel was opened on April 15th, 1964, in August 1987 it was officially named the Lucius J. Kellam Jr. Bridge-Tunnel after one of the civic leaders who worked for its development. However, it still is best known as Chesapeake Bay Bridge-Tunnel. The bridge part of the Chesapeake Bay Bridge-Tunnel as far as I can know is 15.6 Miles long which is why this bridge is placed at number at the worlds 9th longest bridge and 7th longest over water and 4th

China has opened the world's longest cross-sea bridge - which stretches five miles further than the distance between Dover and Calais. The Jiaozhou Bay bridge is 26.4 miles long and links China's eastern port city of Qingdao to the offshore island Huangdao. The road bridge, which is 110ft wide and is the longest of its kind, cost nearly £1billion to build. A bridge over misty waters: The immense £1billion structure which is supported by more than 5,000 pillars stretches for 24 miles along China's eastern port city of Qingdao to the offshore island Huangdao Chinese TV reports said the bridge passed construction appraisals on Monday and it, along with an undersea tunnel, would be opened for traffic today. It took four years to build the bridge, which is supported by more than 5,000 pillars across the bay, and it is almost three miles longer than the previous record-holder - the Lake Pontchartrain Causeway in Louisiana. That structure features two bridges r

A company in Brazil which name is Suite Vollard builded a building in which each floor can rotate 360 degrees. Each building has 11 apartments and each apartment can spin individually in any direction. One rotation takes a full hour, but apartment owner can set rotation speed through apartment control panel. Facades are made of three different types of glass which give wonderful effects when building spins during the sunset. Cost of each apartment is $US 300,000.000.

The hybrid diesel locomotive is an incredible display of power and ingenuity. It combines some great mechanical technology, including a huge, 12-cylinder,  two-stroke diesel engine , with some heavy duty  electric motors  and generators, throwing in a little bit of computer technology for good measure. This 270,000-pound (122,470-kg) locomotive is designed to tow passenger-train cars at speeds of up to 110 miles per hour (177 kph). The diesel engine makes 3,200  horsepower , and the generator can turn this into almost 4,700 amps of electrical current. The four drive motors use this electricity to generate over 64,000 pounds of thrust. There is a completely separate V-12 engine and generator to provide electrical power for the rest of the train. This generator is called the  head-end power unit . The one on this train can make over 560 kilowatts (kW) of electrical power. This combination of diesel engine and electric generators and motors makes the locomo­tive a  hybrid vehicle . In t
