Golf-cart
A golf cart (alternatively known as a golf buggy or golf car) is a small motorized vehicle designed originally to carry two golfers and their golf clubs around a golf course with less effort than walking. Over time, variants were introduced that were capable of carrying more passengers, had additional utility features, or were certified as a street legal low-speed vehicle. A traditional golf cart, capable of carrying two golfers and their clubs, is generally around wide, long and high, weighing between and capable of speeds up to about . The price of a golf cart can range anywhere from under US$1,000 to well over US$20,000 per cart, depending on how it is equipped. History Reportedly, the first use of a motorized cart on a golf course was by JK Wadley of Texarkana, who saw a three-wheeled electric cart being used in Los Angeles to transport senior citizens to a grocery store. Later, he purchased a cart and found that it worked poorly on a golf course. The first electric ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Melex
Melex is an electric vehicle produced by a company of the same name in Mielec, Poland. It has been in production since 1971. The car, having full necessary equipment such as headlamps and seatbelts, is very quiet and does not pollute the environment, so it is usually used in places where standard cars are not allowed. It is also smaller but slower than them – the maximum speed is about 30 km/h or 19 mph, depending on the version. Depending on jurisdiction, some versions may require a driver's license to operate because of their size. At first, the cars were used as golf carts, but now there are many versions that include: * Passenger/Tourist versions (max 8) * Truck versions (up to 1250 kg of cargo), * Special (including: ambulances, hearses etc.) Typical uses include quiet places, such as parks, zoological gardens, cemeteries or in factories A factory, manufacturing plant or a production plant is an industrial facility, often a complex consisting of sever ...

Golf
Golf is a club-and-ball sport in which players use various clubs to hit balls into a series of holes on a course in as few strokes as possible. Golf, unlike most ball games, cannot and does not use a standardized playing area, and coping with the varied terrains encountered on different courses is a key part of the game. Courses typically have either 18 or 9 ''holes'', regions of terrain that each contain a ''cup'', the hole that receives the ball. Each hole on a course contains a teeing ground to start from, and a putting green containing the cup. There are several standard forms of terrain between the tee and the green, such as the fairway, rough (tall grass), and various ''hazards'' such as water, rocks, or sand-filled ''bunkers''. Each hole on a course is unique in its specific layout. Golf is played for the lowest number of strokes by an individual, known as stroke play, or the lowest score on the most individual holes in a complete round by an individual or team, k ...

Vespa
Vespa () is an Italian luxury brand of scooter (motorcycle), scooters and mopeds manufactured by Piaggio. The name means wasp in Italian. The Vespa has evolved from a single model motor scooter manufactured in 1946 by Piaggio & Co. S.p.A. of Pontedera, Italy to a full line of scooters and one of seven companies today owned by Piaggio. From their inception, Vespa scooters have been known for their painted, pressed steel unibody which combines, in a unified structural unit, a complete cowling for the engine (enclosing the engine mechanism and concealing dirt or grease), a flat floorboard (providing foot protection), and a prominent front fairing (providing wind protection). History After World War II, in light of its agreement to cease war activities with the Allies, Italy had its aircraft industry severely restricted in both capability and capacity. Piaggio emerged from the conflict with its Pontedera bomber plane plant demolished by bombing. Italy's crippled economy, and t ...

Electric Grid
An electrical grid is an interconnected network for electricity delivery from producers to consumers. Electrical grids vary in size and can cover whole countries or continents. It consists of:Kaplan, S. M. (2009). Smart Grid. Electrical Power Transmission: Background and Policy Issues. The Capital.Net, Government Series. Pp. 1-42. * power stations: often located near energy and away from heavily populated areas * electrical substations to step voltage up or down * electric power transmission to carry power long distances * electric power distribution to individual customers, where voltage is stepped down again to the required service voltage(s). Grids are nearly always synchronous, meaning all distribution areas operate with three phase alternating current (AC) frequencies synchronized (so that voltage swings occur at almost the same time). This allows transmission of AC power throughout the area, connecting a large number of electricity generators and consumers and potenti ...

Solar Power
Solar power is the conversion of energy from sunlight into electricity, either directly using photovoltaics (PV) or indirectly using concentrated solar power. Photovoltaic cells convert light into an electric current using the photovoltaic effect. Concentrated solar power systems use lenses or mirrors and solar tracking systems to focus a large area of sunlight to a hot spot, often to drive a steam turbine. Photovoltaics were initially solely used as a source of electricity for small and medium-sized applications, from the calculator powered by a single solar cell to remote homes powered by an off-grid rooftop PV system. Commercial concentrated solar power plants were first developed in the 1980s. Since then, as the cost of solar electricity has fallen, grid-connected solar PV systems have grown more or less exponentially. Millions of installations and gigawatt-scale photovoltaic power stations continue to be built, with half of new generation capacity being solar in 2021. ...

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 ...

Photovoltaics
Photovoltaics (PV) is the conversion of light into electricity using semiconducting materials that exhibit the photovoltaic effect, a phenomenon studied in physics, photochemistry, and electrochemistry. The photovoltaic effect is commercially used for electricity generation and as photosensors. A photovoltaic system employs solar modules, each comprising a number of solar cells, which generate electrical power. PV installations may be ground-mounted, rooftop-mounted, wall-mounted or floating. The mount may be fixed or use a solar tracker to follow the sun across the sky. Photovoltaic technology helps to mitigate climate change because it emits much less carbon dioxide than fossil fuels. Solar PV has specific advantages as an energy source: once installed, its operation generates no pollution and no greenhouse gas emissions, it shows scalability in respect of power needs and silicon has large availability in the Earth's crust, although other materials required in PV system m ...

Box Truck
A box truck—also known as a box van, cube van, bob truck or cube truck—is a chassis cab truck with an enclosed cuboid-shaped cargo area. On most box trucks, the cabin is separate to the cargo area; however some box trucks have a door between the cabin and the cargo area. The difference between a box truck and a van is that the cargo van is a one-piece (unibody), while a box truck is created by adding a cargo box to a chassis cab. North American usage Box trucks are typically in length and can range from Class 3 to Class 7 (12,500 lb. to 33,000 lb. gross vehicle weight rating). They often have a garage door-like rear door that rolls up. They are often used by companies transporting home appliances or furniture, or are used as moving trucks which can be rented by individuals. Ford, Dodge and Chevrolet/ GMC have historically been the most common manufacturers of conventional cab/ chassis to which the cargo box is attached by various producers (called body ...

Dump Truck
A dump truck, known also as a dumping truck, dump trailer, dumper trailer, dump lorry or dumper lorry or a dumper for short, is used for transporting materials (such as dirt, gravel, or demolition waste) for construction as well as coal. A typical dump truck is equipped with an open-box bed, which is hinged at the rear and equipped with hydraulic rams to lift the front, allowing the material in the bed to be deposited ("dumped") on the ground behind the truck at the site of delivery. In the UK, Australia, South Africa and India the term applies to off-road construction plants only and the road vehicle is known as a tip lorry, tipper lorry (UK, India), tipper truck, tip truck, tip trailer or tipper trailer or simply a tipper (Australia, New Zealand, South Africa). History The dump truck is thought to have been first conceived in the farms of late 19th century western Europe. Thornycroft developed a steam dust-cart in 1896 with a tipper mechanism. The first motorized dump truck ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flatbed Truck
A flatbed truck (or flatbed lorry in British English) is a type of truck which can be either articulated or rigid. As the name suggests, its bodywork is just an entirely flat, level 'bed' with no sides or roof. This allows for quick and easy loading of goods, and consequently they are used to transport heavy loads that are not delicate or vulnerable to rain, and also for abnormal loads that require more space than is available on a closed body. Road trucks A flatbed has a solid bed, usually of wooden planks. There is no roof and no fixed sides. To retain the load there are often low sides which may be hinged down for loading, as a 'drop-side' truck. A 'stake truck' has no sides but has steel upright pillars, which may be removable, again used to retain the load. Loads are retained by being manually tied down with ropes. The bed of a flatbed truck has tie-down hooks around its edge and techniques such as a trucker's hitch are used to tighten them. Weather protection is optiona ...
