Present commuters often does frequent change in gears,clutching because of this much of the fuel is lost without any useful output.

System Design:
The method uses locking arrangement of fuel just entering before the cylinder during the time of clutching.The system cannot be applied to the vehicle at neutral as there is a chance of engine going dead. But using it during the transition period of the gears can result to saving some amount of fuel.The GTFL can be achieved by constructing a flap (similar to our food pipe to wind pipe flap) which is directly controlled by pressing of clutch.A lever mechanism is placed at the bottom of clutch pedal in such a way that it directly ...

In this era of fast growing medical and health facilities, there are still a considerable amount of people who are paraplegic; they are either born or became so in their lifetime. These people find it very difficult to move from one place to another or need to depend on others most of the time for the same. Obviously a wheelchair is the best option that will help them greatly, but often, a quadriplegic person may not be able to handle a wheelchair easily. They have to extensively depend on other people as they cannot move a wheelchair on their own and often become bedridden.

Many powered wheelchairs are commercially available that are either too expensive or may not be ...

Many parts of the world, e.g., Africa, Middle East, Southern Asia and Australia, have severe shortages of fresh water for agriculture, let alone for drinking. Many of these locations are close to large saltwater bodies with plenty of sunlight available year round. Thus, saltwater can be directly used for agriculture by combining greenhouses with concentrated solar power to desalinate saltwater to provide fresh water. Solar photovoltaic solar panels can be added to run the associated electrical system such as refrigeration units, pumps, fans, lighting, etc. to make the greenhouse units fully self sustaining. Sustainable engineering is achieved by harmoniously utilizing nature’s abundant and free provisions (solar power, wind, sea water, etc.) in a way that is both beneficial for ...

Many people believe that perpetual motion is impossible...however doesn't piezo electricity yield convertible electromotive force? Unlocking the electric motor allowing for the commutator to advance also overcomes resistance of the field for electrical generation by increasing inertia with a given electromotive force.

Q: How does your design work?
A:Self charging active over unity. The system starts with compressed argon released upon impeller generating electricity and this moves the armature of an electric motor,..and two generators, one a transonic propeller that also generates and compresses the argon. The electric motor's commutator is also advanced by electro-magnetic clutch advancing the launch point of the armature. This "effect" removes the limit of rotation for given input current (with the exception of mechanical ...

Spherical NanoDiamond coatings offer exceptional levels of safety in the restricted markets of Aerospace, Avionics, Jet Aircraft, Helicopters, Sea going vessels and Railroad. Ultra hard and slick diamond coatings applied to Commercial and Military gasoline, diesel, LPG and jet engines, gearboxes, hydraulics, cables, gimbals and wheel bearings not only protects against part failure, treated parts have lasted up to 30 times longer than possible with chemical lubrication. An added benefit is increased fuel efficiency upto 60% in multi point treatments.

Metal on metal contact is virtually eliminated and in the case of jet engines and landing wheel bearings, effortlessly gliding, cool surfaces of diamond against diamond are essential, as represented in the short video presentation of diamond coatings vs ...

Craft shall go faster, farther and carry more than any before on the same weight and power, and will do so as boat, sailboat, hydrofoil-boat, hydrofoil-sailboat, WIG or airplane. Technologies, components, and companies that can build it, exist. It will be made for purposes of business, pleasure and/or otherwise.

88-footer by 28-feet-beam catamaran, 40tons loaded with 3000kW electric drive installed, cruises at 100knots and goes 3600miles on 5tons fuel at less than 1000BHP, sprints to 195knots on 8000BHP, and clocks Mach0.45 with sails!

Incredible? With Variable Geometry is how.

1 pair variable-geometry sails can be made to deploy any required area between maximum 2447.4ft2 and minimum 262.7ft2 at AOA versus any wind direction to produce corresponding thrust and speed, ...

45 years ago the Mallory Battery Company of Canada developed a powerful D size cell explicitly for use in very low temperature applications.

This design idea brings forward and enhances that 45 year old technology which, in 1967, was far ahead of its time and by utilizing advanced features and incorporating updates to relevant aspects of the technology which came about over the past 45 years, battery systems which are cheaper, lighter, and with less volume than the competing technologies today are possible.

The Mallory Battery Company of Canada D cell had a significant technological edge in 1967, but it was an expensive process at that time. The novelty was the development of an anode electrode which ...

A liquid fuel missile was designed, built and tested. Design calculations for the two engines and propulsion systems were performed and the engines were constructed to those specifications. A static test stand was constructed and instrumented to evaluate engine performance during full duration static firings. The engine proved successful and it was incorporated into the flight vehicle. The first missile was successfully launched. In the area of guidance, it was decided that the rocket should be ballistic and only fin stabilized. The initial vehicle parameters were:
Thrust: 1000 lbs.
Burn time: 15 sec
Oxidizer: Liquid Oxygen
Fuel: Kerosene
Feed system: 3000 psi nitrogen
Guidance: Fin stabilized

The rocket when launched left the rail at an angle of 45 degrees ...

This invention relates to (a) ducted turbine(s) coupled with (a) generator(s), driven by the airstream of a moving vehicle. This unit(s) can be installed into existing aerodynamic rooftop-fairings of trucks, and / or be part of specially designed aerodynamic rooftop, or in the case of trains, in front of or on top of railroad cars.

Transportation of goods of all kinds affects the global economy. Airstream powered turbines can radically diminish fossil fuel consumption and therefore lower operating costs, while at the same time diminishing the carbon footprint of these vehicles.

The primary objective of this invention is to use the airstream of moving vehicles to produce electrical power. The power can be stored for other uses like refrigeration ...

For decades aerospace engineers have been warning of pollution saturation in the stratosphere/troposphere regions where commercial jets operate, and of the consequences of elevated ground level ozone generated at airports. This project initiates development of a hybrid aircraft engine that produces no unburned hydrocarbons at idle, low NOx at takeoff, and low CO2 at cruise.

SDGroup’s patent pending propulsion system consists of an electric motor–driven ducted fan in the forward section of the engine nacelle. Rearward is a radiant energy combustor that burns fuel stoichiometrically inside a recuperated ceramic tube. The burner is tuned to emit predominantly in the 300 to 1800 nanometer wavelength, matching the operating bandwidth of concentrating photovoltaic (CPV) cells. These cells line the ...
