The University of Louisville ASME Chapter is designing a fully enclosed, 3-wheel, recumbent utility bike. The design includes provision for over 13 cubic feet of storage capacity by employing two side pods and a rear cargo area. The amount of cargo space allows for the hauling of a full load of grocieries, which was the intent of the design. The entirely carbon fiber construction of unidirectional tubes and integral 00, ± 600 panels makes the frame lightweight and durable, weighing only 16lbs. The full enclosure allows for riding in inclement weather conditions. A stepper motor tied to the drivechain charges a 100 Farad capacitor, which will in turn power an LED lighting system that powers headlights and tail- and ...

Some years ago a design student solicited help for a class project to design the bicycle of the future. He needed a new propulsion system that would allow new design freedoms.
I found this challenge very exciting.

I proposed eliminating the mechanical chain and gearing system with electronics. The pedals would connect directly to a generator that would drive two hub motors. There would no longer be the constraints of a chain connecting from the pedals to the rear wheel. The braking would be accomplished by turning the hub motors into generators and storing the energy in a small battery or capacitor. This would greatly enhance the safety of city driving. There is always the temptation to coast through ...

In most air-cooled heat exchangers, the construction utilizes a tube, through which the fluid passes, and fins over which the air passes to remove the heat. Some present units use an aluminum tube and an aluminum fin which are bonded together through a high temperature brazing process. The fin or the tube is usually clad with an alloy to produce the bond. This system requires a significant amount of heat as well as some inert gas to maintain a brazing atmosphere to produce the bond.

The conept being submitted produces a tube and fin that is roll formed to produce a serrated fin. This concept eliminates the brazing process and saves considerable energy. The tube ends are processed further ...

An effective, efficient, and safe air transportation system for moving people and goods is an important part of our national infrastructure; to be competitive globally, it's important that infrastructure is developed, maintained, and updated. If we fail in this, other nations will become increasingly competitive and eventually eat our lunch.

A threat to air travel is that of a collision with another aircraft. The NTSB has a number of investigations underway of recent such incidents. On May 21 a conflict occurred between a 747 and an A319 at Anchorage, and in April two, between a 737 and a news helicopter at Huston, and between a 737 and a Cessna 172 at Burbank. In Aug. of '09, because of home ...

The US and world economy is impeded by the slowness of traffic during rush hours. Reducing the traffic jam problem, on the existing roads infrastructure can have a dramatic improvement on many aspects of our lives. This design idea can do just that using smarter Brake Lights or by mounting a small simple device at back and front of vehicles not more expensive than a TV remote control.

The more devices like that on the road the better the traffic will shape, even without requiring all vehicles to have the device installed at once.

If you observe traffic patterns on congested highways, you will notice that above certain density threshold the flow becomes uneven and worm like. The cars ...

The eventual shift from our dependence on fossil fuels to sustainable, alternative energies has been exemplified by personal transportation. We rely on the high energy density of petroleum products to power our vehicles, but the rise of hybrid and electric vehicles in recent years has shown hints of the future to come. However, the shift has been gradual, mostly due to increased costs for only limited efficiency gains.

Hybrid electric vehicles (HEV) combine the flexibility of the ICE with the efficiency of the electric motor. Regenerative braking, recapturing the energy normally lost during deceleration, adds to the vehicle's range and efficiency, but current battery technology's power density is a critical limiting factor in HEV appeal. Vehicular kinetic energy can ...

My idea for this contest is an Integrated Vision System. This, in a sense, is a way that the VEHICLE, along with the driver and/or passengers can SEE. The IVS will speak to the driver like a modern GPS System to allow the driver to keep their eyes on the road. On roads with limited visibility, this system will allow the driver and passengers to see farther than normal using infrared sensors or a radar of a specific radius. These sensors and radars will be able to pick up ANY objects on and near the road within this specific radius. The IVS will outline any moving objects within the cars specific radius using its technology, whichever that may be. ...

FUELING INTERGALACTIC PROPULSION SYSTEMS
Don Hill

Propelling spaceships through deep space requires ships to carry huge amounts of fuel to escape the gravitational pull on the ship. Once a space ship escapes the pulls of gravity within a solar system, the energy required to control the velocity of the ship becomes extremely small. With no added force, the ship will follow a trajectory of a gravity-controlled arc around nearby bodies and Black Holes at the center of the Universe(s). When energy is applied, the ship will enter a new orbital level much as electrons do when accelerated within an atom. The same basic laws of gravity apply. Study electron flow to gain insight to understanding intergalactic travel possibilities.

What ?. A windshield wiper system that significantly improves the safety of most types of motor vehicles.

How ?. The system fully wipes off all precipitation (rain, snow, etc.) from the windshield regardless of intensity yet the wiper’s sweeping motion is not perceived by vehicle occupants. This is achieved by increasing the wiper’s speed sufficiently above the occupant’s awareness. The system exploits the functioning of neurophysiological perception mechanism of vision: the eye cannot register any motion faster than a certain threshold as is the case of TV or PC monitors.

In the traditional systems, the speed at which Conventional Windshield Wipers (CWW) sweep the windshield in semi-circular motion can be adjusted either manually by the driver or automatically with ...

I am building a gyroplane that will run on water. By using the altenator at 220volts to separate the water into hydrogen and oxygen I will then remix them to run the engine in other words I will design a fuel cell produce what I need when I need it. Then I wont have to worry about storing hydrogen or oxygen so I wont have to deal with goverment intrusion and it will be a simple matter of filling up with water, salt water clean water tap, any type of water. So that means occasionally cleaning the fuel cell.
It's all in the design of the fuel cell with 220 volts. I can arc a lot of hydrogen and ...
