Nowadays we are using fossils fuels for running an I.C engine to produce electric energy. This fossil fuel produces harmful byproducts and costly. So here we are using water as a fuel to generate power (electricity).
When we introducing anode and cathode into the water the positive charged hydrogen is attracted by cathode and negative charged oxygen is attracted by anode. Here the hydrogen and oxygen are disassociated to form HHO. We can directly feed this HHO into IC engines for running. The engine shaft is connected along with the alternator produces current.
The H2O molecule is electrically neutral, but the positive and negative charges are not distributed uniformly. The electronic (negative) charge is concentrated at the oxygen end of the molecule, owing partly to the nonbonding electrons, and to oxygen's high nuclear charge which exerts stronger attractions on the electrons. This charge displacement constitutes an electric dipole, represented by the arrow at the bottom; you can think of this dipole as the electrical "image" of a water molecule.
The Wind Tamer concept is a ducted rotor design. The wind tamer also utilizes an increased blade number and does not need an additional tail to keep it aligned into the wind.
Direct Axis Wind Turbine (DAWTs) have been reported have a greater efficiency than conventional Horizontal Axis Wind Turbine (HAWTs), based on the rotor stream even exceeding the theoretical limit of efficiency of extracting power from the wind, the so called Betz limit of 59.3% , based on the swept area of the rotor. Certain researchers indicated the efficiency increase is caused in part by the diffuser enabling a greater pressure drop across the rotor blade 1 others feel a larger stream tube is captured increasing the mass flow rate and hence the momentum exchange to the rotor. DAWTs differ additional advantages in addition to increased augmentation, including minimizing tip losses and being less yaw sensitive the HAWTs.

Development of AC And Refrigeration Using Exhaust Heat From Car
Student: Mithun Muralidharan & Asik Sam
Mentor: Prof. R. Chandrasekar, Assistant Professor
Funded by Centre of Excellence, MSME, Indian Institute of Sciences, Bangalore, Rs 1,42,800/-
Vapour compression refrigeration cycle is generallyused to produce cooling effect.
Compressor runs on engine power and consumes around 10% of the total power produced by Engine.
Large amount of heat, around 60 % is going as waste in exhaust gas.
Produces the cooling effect by utilizing waste heat from exhaust gas.
It is run on the principle of vapour absorption refrigeration cycle.
It uses ammonia (refrigerant) water (absorbent) and hydrogen to accomplish its cooling effect.
Mileage Promoter Gears (MPG)
Funded by MSME, Government of India, New Delhi, Rs 6.27 lakhs
Student: S.Alagappan, Automobile Engg
Mentor: Dr.A.Nagappan, Principal
For the improvement in fuel efficiency / increasing the mileage and performance, normal gear system is used in our regular use by changing the gears in a simple ratio. Usually if the gear size is reduced the torque will be decreased proportionally. But in this project, the torque is trade offbetween the mileage and speed. This project uses a simple gear transmission kit which drastically improves the performance, speed and mileage of the vehicle. This saves a huge amount of fuel and provides a smooth drive. In this project, gears with special transmission system is modified which can be used in two wheeler vehicles.
The kit increases the mileage in any two wheeler vehicle. It is economic and has many environmental advantages. Hence the main uniqueness of this innovation is promoting mileage, and fuel economy using gears with compensating of torque.

Sequence of Processes
The spice to be ground is cleaned manually and fed in to the hopper.
From the outlet of the hopper the spice enters in to the vibratory feeder.
It is positioned with a small inclination towards the entry of the helical screw conveyor.
The speed of screw conveyor is reduced through reduction pulley.
Speed of the screw conveyor is 10 rpm for feed rate of 12kg/hr.
The liquid nitrogen is passed through the pre-cooler unit.
The spice is allowed to enter into the grinder after passing through the pre-cooler.
The grinding takes place at the pre-decided temperature in the range of -200°C to -70°C.
Spice gets crushed between the studs and comes out through an optional sieve as a ground product.
The flow rate of liquid nitrogen is adjusted by the valve in the transfer line.
The powder is collected at chute and the nitrogen vapour is let out.
Food Feeding Robot For Physically Challenged Persons
Student Name: Sivanadham, Mechanical
Mentor: Prof. N.Natarajan, Associate Professor
A three degrees of freedom robot designed to feed the food for aged and physically challenged persons (Specially for handless persons, Soldiers loss their hands in war)
A simple binary controller used to the motors used in the robots.
Leg operated switches are used.
The end effector of the robot designed for handle the spoon and water cans.
The binary switches pressed by leg in an sequence order the robot movement is achieved
Based on the practice of the user the robot scope the food from plate and feed to the user.
