Tata -  Air-Pod -  Compressed Air Car

 

A compressed air car is a car that uses a motor powered by compressed air. The car can be powered solely by air, or combined (as in a hybrid electric vehicle) with gasoline, diesel, ethanol, or an electric plant with regenerative braking.

Maglev Trains

 (Run by Electro-Magnetic Levitation)

 

 

 

Maglev, or magnetic levitation, is a system

where trains do not run on rails but 'float' on a

magnetic field enabling very fast, smooth journeys.

 

 

In current electromagnetic suspension

(EMS) systems, the train levitates above

a steel rail while electromagnets,

 attached to the train,  are

oriented toward the rail from below.

Maglev  (Electro-magnetic Levitation) Trains

 

Maglev (derived from magnetic levitation) is a system of transportation that uses magnetic levitation to suspend, guide and propel vehicles with magnets rather than using methods such as wheels, axles and bearings. With maglev, a vehicle is levitated a short distance away from a guideway using magnets to create both lift and thrust. High-speed maglev trains promise dramatic improvements for human travel if widespread adoption occurs.

 

Hamburg, Germany 1979 - First Maglev

Transrapid 05 was the first maglev train with longstator propulsion licensed for passenger transportation. In 1979, a 908 m track was opened in Hamburg for the first International Transportation Exhibition.

Maglev trains move more smoothly and somewhat more quietly than wheeled mass transit systems. Their non-reliance on friction means that acceleration and deceleration can surpass that of wheeled transports, and they are unaffected by weather. The power needed for levitation is typically not a large percentage of the overall energy consumption;most of the power is used to overcome air resistance (drag), as with any other high-speed form of transport. Although conventional wheeled transportation can go very fast, maglev allows routine use of higher top speeds than conventional rail, and this type holds the speed record for rail transportation. Vacuum tube train systems might hypothetically allow maglev trains to attain speeds in a different order of magnitude, but no such tracks have ever been built.

Compared to conventional wheeled trains, differences in construction affect the economics of maglev trains. With wheeled trains at very high speeds, the wear and tear from friction along with the concentrated pounding from wheels on rails accelerates equipment deterioration and prevents mechanically-based train systems from routinely achieving higher speeds. Conversely, maglev tracks have historically been found to be much more expensive to construct, but require less maintenance and have low ongoing costs.

Despite decades-long research and development, there are presently only two commercial maglev transport systems in operation, with two others under construction. In April 2004, Shanghai began commercial operations of the high-speed Transrapid system. In March 2005, Japan began operation of the relatively low-speed HSST "Linimo" line in time for the 2005 World Expo. In its first three months, the Linimo line carried over 10 million passengers. South Korea and the People's Republic of China are both building low-speed maglev lines of their own design, one in Beijing and the other at Seoul's Incheon Airport. Many maglev projects are controversial, and the technological potential, adoption prospects and economics of maglev systems have often been hotly debated. The Shanghai system has been accused of being a white elephant.

High-speed monorail train called the Transrapid is a German-made train that uses magnetic Levitation technology. This train has been running in Shanghai, China. Shanghai Maglev Train running with the distance is 30 km from the airport in 7 minutes 20 seconds, with an average speed of 250 km / h (160 mph) and a peak speed of 431 km / h (268 mph). Monorail Transrapid train is not implemented for long distances between cities.

 

 

 

High Speed MAGLEV train shock wave 430 KPH  ( 5 mins)

 

for Shanghai High speed train passing on coming train with shock wave... the other train is over 300 feet (100m) long yet passes in the blink of an eye. the Maglev high-speed train (based on German Transrapid technology) can accelerates to a speed of 430 km/h. The 30-km line (constructed between 2001 and 2004) runs between the Shanghai Lujiazui financial district and Pudong Shanghai International Airport whereby a ride takes about 8 minutes. The Transrapid in Shanghai has a design speed of over 500 km/h (310 mph) and a regular service speed of 430 km/h (267 mph). Shanghai Maglev is the world's fastest railway system in commercial operation. Other Maglev lines within China may follow.
