FLAT GENERATOR

This invention relates to an electric generator. The present day electric generator normally works on the principle of dynamically induced e.m.f. in conductor/s housed within a rotary armature lying in a strong magnetic field. This generator has moving parts. An external mechanical force is essential for this present day rotary generator.

Flat Generator avoids the above said necessity of an external mechanical force thus there is no necessity of any prime mover.

According to Faraday's laws; " As the rate of change of flux linkages increases, induced emf also increases".

In the invented Flat Generator, the rotary ...

Flying Wind Turbine

An airborne wind turbine is a design concept for a wind turbine with a rotor supported in the air without a tower, thus benefiting from more mechanical and aerodynamic options, the higher velocity and persistence of wind at high altitudes, while avoiding the expense of tower construction.

Airborne wind turbines may operate in low or high altitudes.

When the generator is on the ground, then the tethered aircraft need not carry the generator mass or have a conductive tether. When the generator is aloft, then a conductive tether would be used to transmit energy ...

Portable electricity is becoming one of the most demanded technologies since the widespread use of portable electronics over the last two decades. Devices with increasing functionability have also increasing power requirements that fall in the limit of current portable generators, ie. batteries. One solution is proposed here consisting of a fuel cell power generator working with hydrogen and ambient air, that has been modified to be able to provide maximum hydrogen-to-electricity energy conversion with minimal use of auxiliary elements to avoid extra volume, weight, and power consumption. Since hydrogen is used as stored energy, this fuel cell opens the ...

This project is about design of series of various processes through which a fuel cycle in an internal combustion engine setup can be created in which there would be no use of refueling the vehicles working on it & also it won't produce any kind of harmful emissions. This is achieved with the help of concepts of Sabatier reaction, CO2 membrane separation method, Reverse hydrogen fuel cell & Combustion of fossil fuels used in the vehicles. Using all this concepts a reversible cycle is created with help of various electrochemical processes. It mainly separates the CO2 gas from the ...

Conversion of biogas to Methanol and application in IC engines

The project presents conversion of biogas to liquid fuel Methanol by Nucleophilic substitution reaction and its application in IC engine by changing valve timing.

A number of environmental and economic benefits are claimed for bio-fuels. Production of bio-methanol from biomass is one of the ways to reduce consumption of crude oil and environmental pollution. Using bio-methanol blended gasoline fuel for automobiles, we can significantly reduce both petroleum use and exhaust greenhouse gas emission. Bio-methanol can be produced from different kinds of raw materials. Conversion technologies for producing bio-methanol from ...

g-EN CO2 Engine harnesses inexhaustible ambient or waste heat and converts it to useful mechanical power, delivers more power than ICE (internal combustion engine) at the same size without burning hydrocarbon fuels, hence no greenhouse gas emissions. That solves the problems on pollutive energy from fossil fuels and deliver unlimited power to every people in any corner on earth.

The patent-pending technology behind it is using a very cold (about -40 degree C) carbon dioxide in a rotary-vane motor to absorb the ambient heat, expand, drive the shaft and exit. The CO2 can still remain very cold after exit ...

Using a simple solar balloon with dimensions at least 50 square ft. to generate a substantial amount of buoyancy. Specializing the shape for heat accumulation and possibly aero dynamics to act as a "a kite that always pushed up" with any angle of wind turbulence. small profile pump and controller to push air out or pull air in. Or the entire balloon system could be a robot that disengages at certain height, descends to re-engages the cables connected to the core after falling to the base of ' giant solenoid' generator. The hollow cylindrical generator will consist of an ...

We all know radiations are electromagnetic in nature. So the basic idea is to filter the electricity from the electromagnetic wave and store it in the form of electricity for future purposes.

# the idea : if we concentrate the radiation on a conductor and place that conductor inside the permanent magnetic field and in some intervals if we vary the concentration of radiation the magnetic flux will vary and due to variation in magnetic flux current will be produced in the conductor we can now store this current in the battery. We can utilize any radiation e.g. sunlight, ...

The proposed modular green roof is applicable to all buildings in rainy and tropical regions of the world. In the proposed system, it has been tried to mitigate or even solve the problems related to the previous systems such as requiring a large installation space, low water storage efficiency, water penetration to the interior part of the building, purification quality etc. This system is a part of the building which does not occupy extra space. In addition to the indirect form of rainwater absorption (through the plant containers), direct form of rainwater absorption (through the earthenware masses with six ...
