Gravity power generation Mechanism

November 6th, 2011 by admin | 44 Comments | Filed in Mechanical Engineering Projects, Power & Energy

The energy sources for man are drying up. The era of fossil fuels is going to end very soon. Scientists are now working on to find new renewable sources of energy. Along with renewable energy sources like light and wind comes gravity.

Gravity is a phenomenon that existed from the very beginning of the universe but only discovered by Sir Isaac Newton not more than 400 years ago. Recently scientists started generating energy from gravity.

The basic concept of a gravity power generating mechanism is simple. When a body goes down from a higher altitude to a lower one its potential energy is converted into kinetic energy via linear motion. This motion is converted circular motion and is then converted to electricity using a… Read the rest

Electrical Power Generation System Using Railway Track

February 4th, 2011 by admin | 111 Comments | Filed in Mechanical Engineering Projects, Power & Energy
The system includes a power source, such as a power generation device or an external powersource. The power co-generation system includes first and second electrical capacitance portions that are electrically coupled to the power source and that are configured to carry positive and negative charges, respectively. The power co-generation system further includes a biasing device that is configured to separate the first and second capacitance portions with respect to one another. Thus, by varying the distance between the capacitance portions in response to a vehicle on the rail, the capacitance portions cooperate to act as a variable capacitor that facilitates the co-generation of power with respect to the system. That is to say, the mechanical energy of the biasing device is converted into electrical energy for the

Air Cars

August 13th, 2010 by CJ Samson | 269 Comments | Filed in Mechanical Engineering Projects, Mechanical Seminar Topics, Power & Energy

We do it every day without thinking. Start the engine, drive around, fill up with fuel, pay a lot of money and pollute the atmosphere some more! But, it doesn’t have to be that way, many alternative sources of fuel are being developed.

Science fiction novelist Jules Verne had predicted that cars would one day run on air.  Guess what the future of fuel is? You guessed it right, its air!  Think about a car that runs on air. The air we breathe, the air that is for free. Imagine, it costs nothing to fill up your car with gas, and that gas also happens to be the same gas that fills our lungs with every breath!

The future of transportation will soon be… Read the rest

Working model of Hovercraft

August 5th, 2010 by CJ Samson | 181 Comments | Filed in Automobiles, Mechanical Engineering Projects

The idea of making a Hovercraft dates back to 1716 when Emmanual Swedenborg recorded a design, but it was short lived.  In 1870, Sir John Thornycroft filled patents involving air lubricated hulls. And it was in 1959 a hovercraft was built, by Christopher Sydney Cockerell  by discovering the Momentum Curtain theory. Hover craft also called Air cushion vehicle (ACV) travels on any kind of flat surface. It is supported by a cushion of pressurized air.

  • Can be powered by one or more engines
  • Small crafts have a single engine with the drive split through a gear box
  • Usually one engine drives the fan responsible for lifting the vehicle
  • The other forces air from

Hydrogen (water) Powered vehicle

July 29th, 2010 by CJ Samson | 234 Comments | Filed in Automobiles, Mechanical Engineering Projects, Mechanical Seminar Topics, Power & Energy

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.

Remote controlled material handling equipment (RCMHE)

July 28th, 2010 by CJ Samson | 103 Comments | Filed in Mechanical Engineering Projects, Mechanical Seminar Topics, Robots

Prior to the introduction of the so called “Material handling equipment” humans had to perform physical labor to carry out heavy duty tasks. This could be made possible by employing a huge number of workers. However, when the goods came in bulk unloading and loading turned out to be a very time consuming affair. The use of Material handling equipment in logistics has played a significant role in making the loading and unloading activities easier and faster.

Ask yourself the question “Why are ‘Remote controlled’ material handling equipment used?” and almost instantly you arrive at the logical answer that the chief benefit would be allowing personal to control their machine from a safe distance.

Remote control can be achieved by two different modes:… Read the rest

Remote controlled material handling robotic crane for Bomb squads

July 27th, 2010 by CJ Samson | 79 Comments | Filed in Mechanical Engineering Projects, Mechanical Seminar Topics, Robots

It might be just a box of tools or a suitcase someone lost, either way suspicious unattended packages are reason enough to clear Airports, Shopping malls or the whole neighborhood. But while most humans are evacuated from the potential blast zone, one team is doing just the opposite. They are coming in for a closer look! And yes, you guessed it.  It is the Bomb squad. But the men in the bomb squad dare not get too close! In the past, they would have been forced to risk their lives inching ever closer to a device that could detonate at any moment.  But now, they need not put their life at stake. It is time to change working the dangerous way. That is, by hand!

Fire Fighting Robot

A robot system for fire fighting in tunnels

Different kinds of accidents are possible in a tunnel but, accidents involving fire are the most dangerous of all. If it is not possible to extinguish the fire in minutes, it would be so hot that human life will be at risk. But, one of the biggest fears among emergency personnel who should respond to tunnel fires is the possibility of finding hazardous material fueling fire! That was exactly what happened on the 13th of May,1949 which resulted in the Holland tunnel fire. When something as grave as that happens, there is threat to life not only because of the rampaging fire but also because of the toxic materials. In such a situation it is best to leave… Read the rest

Pneumatic paper cup forming machine

July 25th, 2010 by CJ Samson | 172 Comments | Filed in Mechanical Engineering Projects

“Pneumatic paper cup forming machine” is a wonderful project topic for mechanical engineering students.

In a pneumatic system, energy is stored in a potential state in the form of compressed air. Working energy is produced in a pneumatic system when the compressed air is allowed to expand. So, in order to do work, a device is required which is able to supply an air tank with sufficient amount of air at a desired pressure. This device usually happens to be a positive displacement compressor.

Advantages of using a pneumatic machine:

1)    Lower cost than Hydraulic Machines

2)    Works on air which is freely available.

3)    Compact when compared with Hydraulic Machines

4)    Energy can be controlled… Read the rest

Solar Powered Air Conditioner

July 24th, 2010 by CJ Samson | 303 Comments | Filed in Mechanical Engineering Projects, Power & Energy

Summer is the time when you wished you had an Air Conditioner. But, you would rather detest the idea because of the staggering electricity bills you would get once you start using the AC. And it would be a miracle if you could use an AC without paying those hefty electricity bills. In that case, it seems a miracle has just happened!

How about utilizing the free energy of the sun to power up your AC?

The hottest months usually, happens to be also the sunniest. You can use the scorching summer heat to actually remove the heat from your room with the help  Photovoltaics (PVs) to power your AC. Photovoltaics are collection of cells which have photovoltaic material that makes use solar radiation… Read the rest
