The Red vehicle shown in these slides is a totally custom, one of a kind automobile called Freedom1.

Freedom1 has a radically tapered front end , including the bumper, the hood and the nose. If this vehicle is about to collide with another vehicle or structure, all the driver must do is steer 6" off center and the vehicle will slide off the oncoming vehicle or structure, resulting in very minimal damage such as scraped paint. A full impact crash or collision is avoided. Even a pedestrian would be pushed aside rather than run over.

Due to the sharp angles on the front of the car, in order to be Crash Avoiding, a number of alterations were necessary to allow for ...

Many metropolitan cities around the world face traffic woes. The traffic causes loss of time, money, causes mental and physical tiredness, reduces work efficiency and causes road rage besides increasing air and noise pollution in the city. Majority of traffic is seen during rush hours in and around the business areas.

Current approaches to counter this are:
• Road widening, which is generally not feasible within the city
• Metro rail, which is expensive to setup, needs more space for infrastructure

Alternative Solution
A simpler and less expensive approach to this can be The Elevated Cycle Paths which run in the city. These cycle paths can be 5-6 lanes (for cycles of course) and may stretch up to ...

People around the world use cars and motorcycles every day. Cars are large, heavily sealed machines that isolate their occupants from the surrounding environment. Waiting in traffic or avoiding near accidents can quickly anger car drivers, partly thanks to the drivers’ detachment from their surroundings. Motorcycles are very open, but are relatively dangerous. Anything, from an uneven road to a strong gust of wind, can immediately become lethal for the rider. Motorcycles also require cumbersome, potentially expensive attachments for transporting large items or a passenger as easily as a car. The demicar seeks to eliminate these problems while being just as convenient as these two forms of rapid personal transportation.

The demicar will rival the car and the motorcycle ...

The automotive industry faces many challenges, including increased global competition, the need for higher-performance vehicles, a reduction in costs and stringent environmental and safety requirements. The materials used in automotive engineering play key roles in overcoming these issues: ultimately lighter materials mean lighter vehicles and lower emissions. Fibre reinforced composites (FRC) are being used increasingly in the automotive industry due to their strength, quality and light weight. The primary use of FRC in automobiles, with the exception of a few specialized low volume vehicles, has been in semi-structural or decorative parts. Use of FRC for primary and secondary structural components, such as body structures, has been very limited till to date.

In addition to materials cost, there ...


The number of disabled persons with limb loss in India was estimated to be 2,17,83,481 during July to December, 2011. They formed about 1.8 percent of the total population.

There were 1,285,000 persons in the U.S.A living with limb loss in 2009. The prevalence rate in 2009 was 4.9 per 1,000 persons

The objective of this paper is to design and fabricate an electric three wheeler. This three wheeler is specially designed for the physically challenged – Hands Impaired people. To serve this purpose a field survey will be done which includes physically challenged persons. The design part deals with the selection of an electric hub motor that is suitable to run the vehicle. Then the ...

A cooling system in automobile is used to remove excess heat produced in the internal combustion engines. Most automobile cooling system consists of the following components: radiator, water pump, cooling fan, pressure cap and thermostat. Of these components, radiator is the most prominent part of the cooling system, because it transfers the heat from the entire system.

The radiators used in automobiles are either rectangular or square shaped, but air blown/sucked by means of fan is circular in area which develops low velocity zones in corners. So, it is proposed to develop a circular radiator which eliminates the corners.

The proposed circular radiator is compact in size as compared with the conventional ones. It has an ...

Railway is one of the best modes of public transportation in the world. It offers more comfortable and fastest journey to the people. Rail is used to reduce the frictional force between the load and track. The centre of gravity and frictional force are the two important parameters where a ground vehicle can be moved from one point to another point. In this context, the law of floatation (Archimedes principle) is found as a key element that reduces the centre of gravity and frictional forces. As per Archimedes statement, when an object is immersed in a liquid, it gains an upthrust known as ‘buoyancy force’ of the object. Now the object is apparently weightless.

The pulling or tractive ...

The efficiency of diesel engines can be increased if the energy in the exhaust gases were better utilized. The invention (USPTO 8,210,136) shown here allows the hot combustion gases to expand a second time within the engine. The power from that secondary expansion is used by the other cylinder’s supercharger. This invention is a two-stroke diesel engine with opposed cylinders. The engine is modular in that additional pairs of cylinders can be ganged together to form a larger flat engine with a central crankshaft.

Here is how it works. The first figure shows a pair of cylinders. Near the end of the power stroke, combustion gases are released to the secondary expansion chamber. A single large valve at the ...



Standard means of converting linear motion into rotary motion is by applying a linear force to the lever arm of of a crank as in piston engines, or a foot pushing on the crank lever on a bicycle pedal. In each case the force applied to the rotating shaft will fluctuate from 0 at TDC to max at halfway and back to 0 at BDC varying with the PROJECTED length of the lever arm at different points of the motion causing a CONSTANTLY ...

I have devised a solution to the hull speed phenomenon, a 150-year-old problem in marine hydrodynamics, which imposes an effective limit on the cruising speed of vessels having displacement mode monohull forms.

I have been granted U.S. Patent 8,991,326 in recognition of my innovation.

Schematic drawings are attached.

Hull forms typically take one of two basic shapes: displacement or planing. There are also hybrid forms, commonly known as semi-displacement or penetrating hulls, which are basically a combination of the first two. Both hull forms have inherent problems.

Planing hulls are energy intensive: once on plane, their power/speed curve is cubic. On plane, they are limited to operating in relatively smooth conditions.

Displacement hull forms are limited by the "hull ...
