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

Hybrid vehicles

August 14th, 2010 by admin | 25 Comments | Filed in Automobiles, Mechanical Seminar Topics, Power & Energy

The dictionary defines hybrid as something of mixed origin. A hybrid vehicle is one that combines a smaller than normal internal combustion gasoline engine with an electric motor. An engine that combines two or more sources of power is called a hybrid engine.

Typical features in a hybrid include the following:
• Produces much less power than an average
• Produces much less pollution than standard gasoline cars
• Usually constructed of ultra light weight materials like carbon fiber or aluminum to overcome the power gap.
• Generally designed to be more aerodynamic than most cars, allowing them to “slice” through the air instead of pushing it out of the way
• A process called regenerative braking is employed to store… Read the rest

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

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.

Hydrogen Powered vehicle

1)      Battery Pack

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

Auto tracking for solar panel to improve performance

June 28th, 2010 by admin | 7 Comments | Filed in Automation, Mechanical Engineering Projects, Power & Energy

The function of a tracking system for a solar panel is to track the position of the sun constantly so that the solar cells receive maximum solar energy and thereby making it fully functional.

This mechanical engineering project idea is about the fabrication of a solar panel auto tracking system. This comes under power and energy projects. The tracking system mostly consists of electronics parts. So the aim of the project sholud not be just about the fabrication of the tracking system but about energy efficianecy achieved by its implementation. It is better to get the advice of your guide on this topic.

The main parts of a solar tracking system are:
1. Solar panel
2. Servo motor or stepper motor (if difficult to find try… Read the rest
