River Wharfe
The River Wharfe ( ) is a river in Yorkshire, England originating within the Yorkshire Dales National Park. For much of its middle course it is the county boundary between West Yorkshire and North Yorkshire. Its valley is known as Wharfedale. The watercourse first becomes known as the River Wharfe at the confluence of Greenfield Beck and Oughtershaw Beck at Beckermonds. Flowing initially through Langstrothdale, it then passes by, or in some cases through, Kettlewell, Grassington, Bolton Abbey, Addingham, Ilkley, Burley-in-Wharfedale, Otley, Wetherby and Tadcaster. It then flows into the River Ouse, Yorkshire, River Ouse near Cawood, North Yorkshire, Cawood. The section of the river from its source to around Addingham is in Upper Wharfedale and has a very different character to the river downstream. The Wharfe is long (before it joins the Ouse), making it the 21st longest river in Britain. It is a public navigation from the weir at Tadcaster to its junction with the Ouse near C ...

Jimi Heselden
James William "Jimi" Heselden OBE (27 March 1948 – 26 September 2010) was an English entrepreneur. A former coal miner, he became wealthy by manufacturing the Hesco bastion barrier system. In 2009, he bought Segway Inc. He died in 2010 from injuries sustained falling from a cliff while riding his own Segway PT. Early life James William Heselden was born in the Halton Moor district of Leeds on 27 March 1948. He attended school in Osmondthorpe, leaving at the age of 15 to work as a labourer and then at collieries in Temple Newsam and Lofthouse. He lost his job in the wave of redundancies that followed the 1980s miners' strike; he spent his redundancy money on renting a workshop, and initially set up a sandblasting business. He then worked on developing and patenting a collapsible wire mesh and fabric container, later called the Hesco bastion, to be used for building flood management and to limit erosion. Career In 1989, Heselden founded Hesco Bastion Ltd to manufact ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Regenerative Braking
Regenerative braking is an energy recovery mechanism that slows down a moving vehicle or object by converting its kinetic energy or potential energy into a form that can be either used immediately or stored until needed. Typically, regenerative brakes work by driving an electric motor in reverse to recapture energy that would otherwise be lost as heat during braking, effectively turning the traction motor into a generator. Feeding power backwards through the system like this allows the energy harvested from deceleration to resupply an energy storage solution such as a battery or a capacitor. Once stored, this power can then be later used to aid forward propulsion. Because of the electrified vehicle architecture required for such a braking system, automotive regenerative brakes are most commonly found on hybrid and electric vehicles. This method contrasts with conventional braking systems, where excess kinetic energy is converted to unwanted and wasted heat due to friction i ...

Brushless DC Electric Motor
A brushless DC electric motor (BLDC), also known as an electronically commutated motor, is a synchronous motor using a direct current (DC) electric power supply. It uses an electronic controller to switch DC currents to the motor windings, producing magnetic fields that effectively rotate in space and which the permanent magnet rotor follows. The controller adjusts the phase and amplitude of the current pulses that control the speed and torque of the motor. It is an improvement on the mechanical commutator (brushes) used in many conventional electric motors. The construction of a brushless motor system is typically similar to a permanent magnet synchronous motor (PMSM), but can also be a switched reluctance motor, or an induction (asynchronous) motor. They may also use neodymium magnets and be outrunners (the stator is surrounded by the rotor), inrunners (the rotor is surrounded by the stator), or axial (the rotor and stator are flat and parallel). The advantages of a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Twist Grip
A twistgrip is a handle that can be twisted to operate a control. It is commonly found as a motorcycle's right handlebar grip to control the throttle, but is sometimes found elsewhere, such as on a bicycle as a gearshift, and in helicopters. History The first use of the twist grip throttle control was on the Roper steam velocipede of 1867-69. Rather than a sleeve that rotated around the handlebar, Sylvester H. Roper's steam motorcycle's entire handlebar rotated, with a dual mode operation. When rotated forward it opened the throttle, and when rotated backwards it applied the spoon brake. ''Motorcycle Consumer News'' design columnist Glynn Kerr said that pioneering this technology was a point in favor of the Roper's precedence as the first motorcycle, in response to ''Cycle World'' Technical Editor Kevin Cameron's position that the 1885 Daimler ''Reitwagen'' was more deserving because it used the more successful technology, internal combustion rather than steam.
