Friction based variable transmissions, in the form of belts and cones, have been in existence for many years. One successful new version, based around ball bearings and shaped steel surfaces, is the NuVinci drive. However, all friction based transmissions suffer from mechanical inefficiency and limited power capability. Innovators have been trying to develop a chain-based variable transmission for over a century. Many concepts have been patented, but all are complex and delicate mechanisms unsuited to mass manufacture; none is in production.

The VariCruz is a remarkably simple chain-linked variable gear transmission that is built from a handful of simple components in circular arrays. Figure 1 shows the heart of the device: an arrangement of sun and planet ...

Construction zones are rarely regarded in a positive light, and for good reasons:
• Commuters languish in construction zones when roads need renovation or find finding alternate routes in an effort to avoid losing precious time to traffic jams.
• Local retail business suffer, losing significant amounts of business in an already challenging economic climate, and occasionally having to close their doors entirely as a result of lost business.
• Construction zones are ripe for injuries and accidents as road workers attempt repairs in close proximity to traffic, and drivers are more likely to experience fender-benders brought on by irritation or distraction.

Much of the time needed to complete road renovations is taken up by detail work; placement of ...

Twice the specific power of regular engines, half the cost, half the weight, 30% more fuel efficient.

With hundreds of millions of small internal combustion engines produced yearly, there is a need for simple and cheap to produce 4-stroke engines. Small part count and simple manufacturing with forgiveness for production tolerances combined with proper sealing, cooling and lubrication are mandatory.

The orbox engine has no gears or valves, but maintains proper sealing, cooling and lubrication. All parts are 2-dimensional simple/cheap to manufacture parts, and can be easily balanced for high speeds. Large openings allow high gas flow and high power density, and simple on-the-fly variable compression allows fuel optimizing and high efficiency. See www.orbox.be

The idea is based ...

My idea is to use linear motion technology and controls to power a vehicle, car or truck by incorporating a circular linear motor in to the wheels of the vehicle. This will greatly improve the efficiency by reducing the power train to one moving ...

A CLUSTER ROCKET ENGINE:A cluster engine is made up of small, easier to develop and less expensive thrusters that provide the engine with greater thrust and versatility.
Typically, for an engine using a cold gas or a pressure-fed liquid chemical, the thrust chamber pressure is the key to establishing its weight. Increasing the chamber pressure in a thruster design and trade study produces several effects: The thruster will tend to be smaller and perform better because of an increased area ratio and to a much lesser extent, an improved combustion efficiency. This is the main concept of a cluster engine.Therefore, the engine weight and propellant quantity will tend to decrease (40% saving over current engines). Having a required surface ...

An electric drive duct fan that can be compacted for storage. This duct fan is designed for a vehicle that can be folded for storage or transportation in the same maner that helicopters are. The incorperated electric motor means that no drive shafts or other complex machinery need to be incorporated to the folding ...

The problem with variable drive systems are that they tend to have a scrubbing effect, at any given speed the friction drive area is one to one in the center of contact but either over drives on one side and under drives on the other. This causes heat, power lose and premature wear. I have solved this problem using a set of cones, one inside the other. The inner cone has a conditioned surface to help grip the outer cone. The outer cone is lined on the inside with a frictional material comparable to the material on automatic clutch discs.
At low speeds the drive cone is positioned near the large end of the driven cone. This ...

The current internal combustion engine will run on hydrogen with some modifications. One vehicle had a range of 600 miles between the hydrogen tank and 10 gallon regular gas tank. The existing fleet of gasoline vehicles could be converted to run on gasoline or hydrogen for the price of a conversion kit. I have seen numbers of $1,000 to $2,000 for the kit. The vehicles could run on hydrogen and use gasoline to venture beyond hydrogen refueling station range.

Hydrogen fuel conversion could be achieved by picking a medium size town that has a small number of gas stations and a reasonable number of autos. Install a hydrogen station fueling port along side the regular gas pumps. The problem ...

"Digitally Timed Gas Mileage" is my invention. It will tell you how much time (hours,min,sec) is left until you have to refuel your car. This will replace the empty/full gauge with a digital clock, showing how much time is left. It will be based off RPM's. There will also be another clock showing how long the car has been running, replacing needing to know how much mileage is on the car. This idea will enhance today's digital and futuristic society, and will bring a new meaning to the word, "convenience." Wouldn't you like to know exactly how much time you have until needing to put more gas in? This also will aid others in a broad spectrum: such as ...

"Digitally Timed Gas Mileage" is my invention for today's interesting car culture. It will tell you how much time (hours,min,sec) is left until you have to refuel your car. This will replace the empty/full gauge with a digital clock, showing how much time is left. It will be based off RPM were 2500 rpm is were it will count down normally and anything above 2500 will cause it to count down quicker and anything below will count down slower 2500rpm is equal to 70 mph. There will also be another clock showing how long the car has been running, replacing needing to know how much mileage is on the car. This idea will enhance today's digital and futuristic society, ...
