Electrical power generation using railway tracks.
Rail based electric power generation system
An electrical power generation system comprises a variable capacitor and a power source. The electrical power generation system is configured to generate electric power via movements of the rail. The power source is used in the form of a generator to prime the variable capacitor that effectively multiplies the priming energy of the power source by extracting energy from the passing vehicle. By alternately priming the variable capacitor using charge from the power source and discharging it at a later time in a cyclic manner to change the capacitance, a significantly large amount of electrical energy is produced due to change in capacitance than from the power source itself.
Electrical power generation using foot step.
Free play Energy has released a human-powered electricity generator for commercial sale. Pushing up and down with your foot on a step-action treadle generates power. The Free Charge can be re-charged by any 110v to 240v wall sockets and power input from other sources such as solar and wind. Free Charge uses a lead acid gel battery which has enough power to jump-start vehicles, boats and many other electric appliances and gadgets. The unit comes with a 7Ah sealed lead acid battery, charge indicator, 3V-12V variable DC output adapter, jumper cables and a 12V cigarette lighter adapter.
Fabrication of solar ups and heating device.
A system for converting solar energy into electric energy at reduced cost makes use of an array of light sensitive, voltage producing solar cells of the flat disc silicon type. To increase power, while using fewer costly cells, each cell of the array has a truncated conical shell mounted on legs at a spaced distance there over, the shell having a mirror-like reflective inner surface. Thus, sunlight is received in the large end and reflected through the small end to the cell. A sealed, weather-tight enclosure for the array, has fluid inlets and outlets for producing heat, the heat conductive shells absorbing and radiating heat.
Electrical power generation using speed breaker.
“POTENTIAL ENERGY TO ELECTRICAL ENERGY CONVERSION” Potential energy can be thought of as energy stored within a physical system. This energy can be released or converted into other forms of energy, including kinetic energy. It is called potential energy because it has the potential to change the states of objects in the system when the energy is released If h is the height above an arbitrarily assigned reference point, then Kinetic energy of an object is the extra energy which it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its current velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes. Negative work of the same magnitude would be required to return the body to a state of rest from that velocity. The kinetic energy can be calculated using the formula: In this project a mechanism to generate power by converting the potential energy generated by a vehicle going up on a speed breaker into kinetic energy. When the vehicle moves over the inclined plates, it gains height resulting in increase in potential energy, which is wasted in a conventional rumble strip When the breaker come down, they crank a lever fitted to a ratchet-wheel type mechanism (a angular motion converter). This in turn rotates a geared shaft loaded with recoil springs. The output of this shaft is coupled to a dynamo to convert kinetic energy into electricity. A vehicle weighing 1,000 kg going up a height of 10 cm on such a rumble strip produces approximately 0.98 kilowatt power. So one such speed-breaker on a busy highway, where about 100 vehicles pass every minute, about one kilo watt of electricity can be produced every single minute.
Intelligent starter of three phase induction motor
Research has picked up a fervent pace in the area of fault diagnosis of electrical machines. Like adjustable speed drives, fault prognosis has become almost indispensable. The manufacturers of these drives are now keen to include diagnostic features in the software to decrease machine down time and improve salability. Prodigious improvement in signal processing hardware and software has made this possible. Primarily, these techniques depend upon locating specific harmonic components in the line current, also known as motor current signature analysis (MCSA). These harmonic components are usually different for different types of faults. However with multiple faults or different varieties of drive schemes, MCSA can become an onerous task as different types of faults and time harmonics may end up generating similar signatures. Thus other signals such as speed, torque, noise, vibration etc., are also explored for their frequency contents. Sometimes, altogether different techniques such as thermal measurements, chemical analysis, etc., are also employed to find out the nature and the degree of the fault. Human involvement in the actual fault detection decision making is slowly being replaced by automated tools such as expert systems, neural networks, fuzzy logic based systems to name a few. Keeping in mind the need for future research, this review paper describes different types of faults and the signatures they generate and their diagnostics' schemes

Fabrication of Solar automatic cell phone charger with pay system
A portable, cellular phone battery charger using solar energy as the primary source of power and including two separate solar panels and a battery/switch-containing unit. The two panels are handedly connected together, and the battery/switch-containing unit is handedly connected to the backside of one of the panels. The assembly is pivot able between a retracted configuration in which the three component parts lie in parallel planes, and a deployed configuration in which the two solar panels lie in one plane and the battery/switch unit lies in another plane angularly intersecting the solar panel plane. The device is selectively operable in three different modes; namely, a first mode in which the solar panels are connected to charge or power a cell phone; a second node in which the solar panels are connected to charge the device's internal battery, and a third mode in which the internal battery is used to charge or power a phone coupled to the device.
