A pulse jet engine is a type of jet engine that uses pulses of combustion rather than continuous combustion to stay in the air, thereby reducing fuel costs and increasing efficiency. While pulse jet engines have been used in many functional jets, they can also be used for a variety of other applications such as water heating, biomass fuel conversion, fog generators, radio controlled aircraft, target drone aircraft, control line model aircraft, and pulse detonation experiments. Pulse jet engines are most often used in unmanned aircraft due to problems with Read More

Natural gas cars are special cars that run using natural gas instead of conventional liquid petroleum fuel like gasoline and diesel. These cars are fitted with special engine modifications or simple add-ons that make the use of natural gas possible. Some conventional cars with internal combustion engines could also be converted into Compressed Natural Gas (CNG) cars by using special conversions and fittings. Natural Gas Natural gas is a fossil fuel which is obtained from petroleum reservoirs usually in a form of a multi-component gas. The gas is normally composed Read More

A Segway is a vertical, mobile vehicle that is able to carry a single person between distances. While a bicycle consists of two wheels and a horizontal frame, a Segway consists of two or four wheels and a vertical frame that balances atop these wheels to steady the rider. Segways run on purely electrical energy and can be taken anywhere pedestrians can go. Segways are large enough to transport a person and yet light enough to carry in one arm. Dynamic Stabilization Dynamic stabilization involves the use of sensors that Read More

Many street lights are equipped with Traffic Signal Preemption systems like the 3M Opticom or the Tomar Strobecom. These systems enable emergency vehicles to change the traffic signals from Red to Green, and to change the traffic signals for others from Green to Red. This enables emergency vehicles to travel more quickly and more safely. These systems operate by means of a receiver mounted on the traffic signal and a transmitted mounted inside the emergency vehicle. The transmitter is an infrared light which is flashed at the receiver. The transmitter Read More

OnStar was developed and deployed by General Motors for the purpose of providing fast and effective response in the event of vehicular accidents. OnStar has now been improved to provide more than the basic services. Now, it provides assistance with directions, car breakdown help as well as communications and leisure services. OnStar is a system for your automobile that performs many different functions, the most advertised being the fact that the company is alerted when you get in a car accident and they respond immediately by contacting you through the Read More

One of the most prominent gauges on an automobile’s dashboard is the speedometer. Its primary function is to give a visual indication of a vehicle’s speed in miles or kilometers (or both) per hour. Since the majority of these devices are still analog, they may require speedometer calibration when new tires are installed, major automotive repair work is completed, or it gives incorrect readings on a consistent basis. When Were Speedometers First Used? Automobile manufacturers first included Speedometers as standard equipment in 1910 as the need to limit drivers’ speeds Read More

Intelligent transportation systems are projects that aim to integrate modern communication and information technology into existing transportation management systems in order to optimize vehicle life, fuel efficiency, safety, and traffic in urbanized cities. The need for intelligent transportation systems stems from the fact that traffic congestion has been increasing all around the world because of increasing population, increasing amount of transportation vehicles and increasing urbanization. Intelligent highways are the new highway traffic analysis and response technology that will be implemented in major cities in the near future in order to Read More

Jets are able to move much faster than other types of aircraft and they especially move faster than regular forms of transportation such as trains and automobiles. In exchange for all the extra speed, however, jet engines must be designed and built differently than normal engines. This article will explain what jet engines do that are so special and list a number of parts that are crucial to the jet engine's ability to generate such high speeds. What Do Jet Engines Do Jet engines, also known as gas turbine engines, Read More

A hybrid airship is an aircraft that combines the technologies found in conventional aircrafts and airships in starting and maintaining its flight. It will have the large airbag within a cylindrical body so it looks like a conventional airship, but it will also have wings and rudders like a regular airplane. Airships, Balloons and Conventional Aircrafts An airship (better known as a dirigible or blimp) is an aircraft that uses a large inflatable compartment or chamber which is filled with a gas. The gas (usually hydrogen or helium) used in Read More

A common law enforcement practice known as "speed traps" or "speed trapping" is based on one universal factor: Almost everyone speeds. Everyone has their reasons but most people speed on occasion just because they can. While this excessive acceleration is usually harmless as drivers have enough time to slow down during emergencies, many fatal car accidents are caused by everyday people who just didn't bother to slow down. Law enforcement personnel struggle to combat this crime but most people slow down when they see a police officer in the area. Read More
