Teardrop Trailer
A teardrop trailer, also known as a teardrop Caravan (towed trailer), camper trailer, is a streamlined, compact, lightweight caravan, which gets its name from its Tears, teardrop profile. They usually only have sleeping space for two adults and often have a basic kitchen in the rear. Teardrop trailers first became popular in the 1930s, when magazines such as ''Mechanix Illustrated'' published Do it yourself, DIY construction plans. The first teardrop designs incorporated standard sheets of plywood with hardwood Stiffening, spars. Teardrop trailers remained popular until the mid-1960s, after which they disappeared from mainstream camping. However, in the late 1990s, plans became available on the Internet and in recent years teardrop trailers have made a resurgence and are again growing in popularity. A teardrop trailer is generally small, ranging from to in width and to in length. They are usually to in height. Wheels and tires are usually outside the body and are covered b ...

Tire
A tire (American English) or tyre (British English) is a ring-shaped component that surrounds a Rim (wheel), wheel's rim to transfer a vehicle's load from the axle through the wheel to the ground and to provide Traction (engineering), traction on the surface over which the wheel travels. Most tires, such as those for automobiles and bicycles, are pneumatically inflated structures, which also provide a flexible cushion that absorbs shock as the tire rolls over rough features on the surface. Tires provide a footprint, called a contact patch, that is designed to match the weight of the vehicle with the bearing strength of the surface that it rolls over by providing a bearing pressure that will not deform the surface excessively. The materials of modern pneumatic tires are synthetic rubber, natural rubber, fabric, and wire, along with carbon black and other chemical compounds. They consist of a tire tread, tread and a body. The tread provides Traction (engineering), traction ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

California's Gold
''California's Gold'' is a public television human interest program that explores the natural, cultural, and historical features of California. The series ran for 24 seasons beginning in 1991, and was produced and hosted by Huell Howser in collaboration with KCET, Los Angeles. The series ceased production when Howser retired in November 2012, shortly before his death on January 7, 2013, although episodes continue to be shown on KCET and are featured on the page at the station's website about his shows. The series theme song is "California, Here I Come." Typically, it is performed by local musicians who may be from a given episode's locale. However some episodes include an old-time recording of the California state song "I Love You, California". Production The minimal production allowed locations and people to remain the focal point of the program. Howser's archives are now housed at Chapman University in Orange, California, and can be streamed online. The decision to dona ...

Alternating Current
Alternating current (AC) is an electric current which periodically reverses direction and changes its magnitude continuously with time in contrast to direct current (DC) which flows only in one direction. Alternating current is the form in which electric power is delivered to businesses and residences, and it is the form of electrical energy that consumers typically use when they plug kitchen appliances, televisions, fans and electric lamps into a wall socket. A common source of DC power is a battery cell in a flashlight. The abbreviations ''AC'' and ''DC'' are often used to mean simply ''alternating'' and ''direct'', as when they modify ''current'' or ''voltage''. The usual waveform of alternating current in most electric power circuits is a sine wave, whose positive half-period corresponds with positive direction of the current and vice versa. In certain applications, like guitar amplifiers, different waveforms are used, such as triangular waves or square waves. Audio a ...

Mains Electricity
Mains electricity or utility power, power grid, domestic power, and wall power, or in some parts of Canada as hydro, is a general-purpose alternating-current (AC) electric power supply. It is the form of electrical power that is delivered to homes and businesses through the electric grid in many parts of the world. People use this electricity to power everyday items—such as domestic appliances, televisions and lamps—by plugging them into a wall outlet. The voltage and frequency of electric power differs between regions. In much of the world, a voltage (nominally) of 230 volts and frequency of 50 Hz is used. In North America, the most common combination is 120 V and a frequency of 60 Hz. Other combinations exist, for example, 230 V at 60 Hz. Travellers' portable appliances may be inoperative or damaged by foreign electrical supplies. Non-interchangeable plugs and sockets in different regions provide some protection from accidental use of appliances ...

Battery (electricity)
An electric battery is a source of electric power consisting of one or more electrochemical cells with external connections for powering electrical devices. When a battery is supplying power, its positive terminal is the cathode and its negative terminal is the anode. The terminal marked negative is the source of electrons that will flow through an external electric circuit to the positive terminal. When a battery is connected to an external electric load, a redox reaction converts high-energy reactants to lower-energy products, and the free-energy difference is delivered to the external circuit as electrical energy. Historically the term "battery" specifically referred to a device composed of multiple cells; however, the usage has evolved to include devices composed of a single cell. Primary (single-use or "disposable") batteries are used once and discarded, as the electrode materials are irreversibly changed during discharge; a common example is the alkaline battery used ...

Galley (kitchen)
The galley is the compartment of a ship, train, or aircraft where food is cooked and prepared. It can also refer to a land-based kitchen on a naval base, or, from a kitchen design point of view, to a straight design of the kitchen layout. Ship's cooking area A galley is the cooking area aboard a vessel, usually laid out in an efficient typical style with longitudinal units and overhead cabinets. This makes the best use of the usually limited space aboard ships. It also caters for the rolling and heaving nature of ships, making them more resistant to the effects of the movement of the ship. For this reason galley stoves are often gimballed, so that the liquid in pans does not spill out. They are also commonly equipped with bars, preventing the cook from falling against the hot stove. A small cooking area on deck was called a caboose or ''camboose'', originating from the nl, kombuis, which is still in use today. In English it is a defunct term used only for a cooking area that is ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Fuel Efficiency
Fuel efficiency is a form of thermal efficiency, meaning the ratio of effort to result of a process that converts chemical potential energy contained in a carrier (fuel) into kinetic energy or work. Overall fuel efficiency may vary per device, which in turn may vary per application, and this spectrum of variance is often illustrated as a continuous energy profile. Non-transportation applications, such as industry, benefit from increased fuel efficiency, especially fossil fuel power plants or industries dealing with combustion, such as ammonia production during the Haber process. In the context of transport, fuel economy is the energy efficiency of a particular vehicle, given as a ratio of distance traveled per unit of fuel consumed. It is dependent on several factors including engine efficiency, transmission design, and tire design. In most countries, using the metric system, fuel economy is stated as "fuel consumption" in liters per 100 kilometers (L/100 km) or kilometer ...

Fender (vehicle)
Fender is the American English term for the part of an automobile, motorcycle or other vehicle body that frames a wheel well (the fender underside). Its primary purpose is to prevent sand, mud, rocks, liquids, and other road spray from being thrown into the air by the rotating tire. Fenders are typically rigid and can be damaged by contact with the road surface. Sticky materials, such as mud, may adhere to the smooth outer tire surface, while smooth loose objects, such as stones, can become temporarily embedded in the tread grooves as the tire rolls over the ground. These materials can be ejected from the surface of the tire at high velocity as the tire imparts kinetic energy to the attached objects. For a vehicle moving forward, the top of the tire is rotating upward and forward, and can throw objects into the air at other vehicles or pedestrians in front of the vehicle. In British English, the fender is called the wing. (This may refer to either the front or rear fenders. Ho ...

Wheel
A wheel is a circular component that is intended to rotate on an axle Bearing (mechanical), bearing. The wheel is one of the key components of the wheel and axle which is one of the Simple machine, six simple machines. Wheels, in conjunction with axles, allow heavy objects to be moved easily facilitating movement or transportation while supporting a load, or performing labor in machines. Wheels are also used for other purposes, such as a ship's wheel, steering wheel, potter's wheel, and flywheel. Common examples are found in transport applications. A wheel reduces friction by facilitating motion by rolling together with the use of Axle, axles. In order for wheels to rotate, a Moment (physics), moment needs to be applied to the wheel about its axis, either by way of gravity or by the application of another external force or torque. Using the wheel, Sumer, Sumerians invented a device that spins clay as a potter shapes it into the desired object. Terminology The English word '':wi ...
