Hydrogen (water) Powered vehicle

September 29, 2011

Not a Gimmick! Finally the science of Hydrogen automotive power has been made a reality! Technically a device that converts the energy stored in hydrogen into motion can be called a Hydrogen engine. Hydrogen would make a great fuel for the environment since burning Hydrogen produces nothing but water!

Hydrogen Powered vehicle essentially consists of the following

1)      Fuel tank

Liquid hydrogen is stored in a tank at the rear of the car and is pumped forward to the fuel cell stack as and when required.

2)      Fuel Cell Stack

When Hydrogen is combined with Oxygen in a fuel cell a chemical reaction creates electricity.

1)      Battery Pack

The battery pack is periodically recharged by the fuel cell. The power from the battery pack is used to provide rapid acceleration.

2)      Electric Motor

The stack provides electricity for the electric motor that powers the vehicle

Right from the year 1625, when Johann Baptista van Helmont discovered the gas, Hydrogen; people were curious enough to find the uses of the new found gas. It nearly took a mind boggling 181 years to develop an internal combustion engine which runs on a mixture of hydrogen and water by the icon of 18th century who is none other than, Francois Issac de Rivaz. The Swiss inventor, is credited with the development and construction of the world’s first IC engine back in 1806. From then onwards, it was always a challenge to develop the best IC engine. This has lead to developing different varieties of engines.

A pictorial representation of the Hydrogen powered vehicle is shown below.

Magnetic Levitation Train

September 29, 2011

Love to turn a 45 minute car ride to an 8 minute blur?

China was the first to country to have an up and running Maglev you could buy tickets to. Back in 1979 the Germans developed the 1st Magnetic levitation (Maglev) train.  The first to overcome the limitation of wheel and rail, because the rail moves entirely without contact!

This is a wonderful topic for your mechanical engineering seminar as well as project if you dare to make a working model.

The functions of the wheel and rail on a normal rail road including support guidance propulsion and braking are accomplished through an electro magnetic levitation and propulsion system. The mechanics have been replaced by electronics. Support Magnets draw the vehicle towards the guide way from below. While, guidance magnets hold’s the vehicle laterally on track. These support and guidance magnets are mounted on both sides of the vehicle along its entire length. An electronic control system ensures that it levitates at a constant height above the guide way. The Maglev train is propelled and braked by a synchronous long stator linear motor. This motor is not located in the vehicle itself but rather in the guide way. It functions on the same principle as a traditional rotating electrical motor, whose stator has been cut open, unrolled and stretched length wise along both sides of the guide way. But, instead of a rotating magnetic field a traveling magnetic field is generated in the windings, one that pulls the vehicle along the guide way without contact.

The guide way can be elevated where it makes ecological sense. in this way it won’t divide the landscape or developed areas and the area beneath the guide way can continue to be used as before. The guide way can be built at ground level to allow easier co location with existing transportation systems. Therefore, the guide way can be adapted to the landscape instead of being the other way round.

Maglev Train

The operation control system controls and safe guards the vehicle’s switches, guide ways and stations along the maglev route. The vehicle communicates with the control system by means of directional radio data transmission. The vehicle’s location is monitored by means of a location reference system integrated into the guide way. The only motor section in operation along the guide way, is the one in which the vehicle is currently traveling. When the vehicle passes from one section to the next, the new motor section is automatically switched on. More power is supplied on gradients and acceleration segments along the route than on flat segments this way the propulsion power is distributed very economically. It is always available exactly where it is needed.

The technology’s success in India could ultimately hinge on a combination public funding and private investments.

The Power Of Foot Steps into Energy

September 28, 2011

A team of college students came together to design a new traffic intersection that transforms the power of footsteps into energy. The theories behind piezoelectricity, or the conversion of movements and vibrations into electricity, have existed for over 100 years. Very few applications of piezoelectricity exist in this modern age. Upon researching this technology, they immediately realized a multitude of different avenues one could take to utilize it.

Piezoelectric plates are placed under the cross-walk so that vibrations and pressure fluctuations caused by cars and pedestrians can be converted into electricity.  The electricity is piped to power street lamps, traffic signals, cameras and other electronic devices located in the vicinity. What an awesome idea for busy metropolises.

September 28, 2011

Voice enabled GPS devices add another level of sophistication to advance GPS navigation market.

01-ford-fiesta-gps enabled car-future car infotainment systems

GPS technology has been developed for military use.The global navigation of naval warships, missiles guidance and movements of troops on the ground has led to the need for advice site precision technology has finally found a strong market for private users and consumers as well. In fact, you can find GPS devices everywhere.

Navigation devices have been recent improvements in the size of the screen, precision and live traffic reports. However, just as the market of cellular telephony, the need for improving the safety and convenience became a priority more than people began to GPS devices in their vehicles. Demand for models activated voice GPS has grown year after year. Hands-free operation was the next logical to include functionality.

Here I posted next generation Ford Fiesta Car Infotainment systems.

The Web Enabled Browser receives the Google Map to the GPS devices when the driver given the street information to voice activated Bluetooth Device. Then the GPS shows the accurate map to the user. If you want navigation which tells the route accurately. So driving made easily. This is the future of driving.
