BMW H2R
The BMW H2R ("Hydrogen Record Car") is a racecar adapted to run on liquid hydrogen fuel. It was conceived and developed in 10 months under the direction of Dr. Raymond Freymann. The H2R’s 6.0-liter V12 engine, which draws on BMW's Valvetronic and Double-VANOS technology, is based on the 760i’s gasoline-fueled powerplant. This H2-powered vehicle generates achieved a top speed of .

Aluminium
Aluminium (aluminum in American and Canadian English) is a chemical element with the symbol Al and atomic number 13. Aluminium has a density lower than those of other common metals, at approximately one third that of steel. It has a great affinity towards oxygen, and forms a protective layer of oxide on the surface when exposed to air. Aluminium visually resembles silver, both in its color and in its great ability to reflect light. It is soft, non-magnetic and ductile. It has one stable isotope, 27Al; this isotope is very common, making aluminium the twelfth most common element in the Universe. The radioactivity of 26Al is used in radiodating. Chemically, aluminium is a post-transition metal in the boron group; as is common for the group, aluminium forms compounds primarily in the +3 oxidation state. The aluminium cation Al3+ is small and highly charged; as such, it is polarizing, and bonds aluminium forms tend towards covalency. The strong affinity tow ...

BMW Art Car Project
The BMW Art Car Project was introduced by the French racecar driver and auctioneer Hervé Poulain, who wanted to invite an artist to create a canvas on an automobile. In 1975, Poulain commissioned American artist and friend Alexander Calder to paint the first BMW Art Car. This first example would be a BMW 3.0 CSL which Poulain himself would race in the 1975 24 Hours of Le Mans endurance race. Since Calder's work of art, many other renowned artists throughout the world have created BMW Art Cars, including David Hockney, Jenny Holzer, Roy Lichtenstein, Robert Rauschenberg, Frank Stella, and Andy Warhol. To date, a total of 20 BMW Art Cars, based on both racing and regular production vehicles, have been created. Frank Stella also made one unofficial art car at the behest of race car driver Peter Gregg. The most recent artist to the join BMW Art Car program is Cao Fei in 2017 with her M6. Artists for the BMW Art Car Project are chosen by a panel of international judges. Accordin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Olafur Eliasson
Olafur Eliasson ( is, Ólafur Elíasson; born 5 February 1967) is an Icelandic–Danish artist known for sculptured and large-scale installation art employing elemental materials such as light, water, and air temperature to enhance the viewer's experience. In 1995 he established Studio Olafur Eliasson in Berlin, a laboratory for spatial research. In 2014, Eliasson and his long-time collaborator, German architect Sebastian Behmann founded Studio Other Spaces, an office for architecture and art. Olafur represented Denmark at the 50th Venice Biennale in 2003 and later that year installed '' The Weather Project'', which has been described as "a milestone in contemporary art", in the Turbine Hall of Tate Modern, London. Olafur has engaged in a number of projects in public space, including the intervention ''Green river'', carried out in various cities between 1998 and 2001; the Serpentine Gallery Pavilion 2007, London, a temporary pavilion designed with the Norwegian architect Kjeti ...

Drag Coefficient
In fluid dynamics, the drag coefficient (commonly denoted as: c_\mathrm, c_x or c_) is a dimensionless quantity that is used to quantify the drag or resistance of an object in a fluid environment, such as air or water. It is used in the drag equation in which a lower drag coefficient indicates the object will have less aerodynamic or hydrodynamic drag. The drag coefficient is always associated with a particular surface area. The drag coefficient of any object comprises the effects of the two basic contributors to fluid dynamic drag: skin friction and form drag. The drag coefficient of a lifting airfoil or hydrofoil also includes the effects of lift-induced drag. The drag coefficient of a complete structure such as an aircraft also includes the effects of interference drag. Definition The drag coefficient c_\mathrm d is defined as c_\mathrm d = \dfrac where: * F_\mathrm d is the drag force, which is by definition the force component in the direction of the flow velocity; * ...

Carbon-fiber-reinforced Polymers
Carbon fiber-reinforced polymers (American English), carbon-fibre-reinforced polymers (Commonwealth English), carbon-fiber-reinforced plastics, carbon-fiber reinforced-thermoplastic (CFRP, CRP, CFRTP), also known as carbon fiber, carbon composite, or just carbon, are extremely strong and light fiber-reinforced plastics that contain carbon fibers. CFRPs can be expensive to produce, but are commonly used wherever high strength-to-weight ratio and stiffness (rigidity) are required, such as aerospace, superstructures of ships, automotive, civil engineering, sports equipment, and an increasing number of consumer and technical applications. The binding polymer is often a thermoset resin such as epoxy, but other thermoset or thermoplastic polymers, such as polyester, vinyl ester, or nylon, are sometimes used. The properties of the final CFRP product can be affected by the type of additives introduced to the binding matrix (resin). The most common additive is silica, but other addit ...

Space Frame
In architecture and structural engineering, a space frame or space structure ( 3D truss) is a rigid, lightweight, truss-like structure constructed from interlocking struts in a geometric pattern. Space frames can be used to span large areas with few interior supports. Like the truss, a space frame is strong because of the inherent rigidity of the triangle; flexing loads (bending moments) are transmitted as tension and compression loads along the length of each strut. History Alexander Graham Bell from 1898 to 1908 developed space frames based on tetrahedral geometry. Bell's interest was primarily in using them to make rigid frames for nautical and aeronautical engineering, with the tetrahedral truss being one of his inventions. Max Mengeringhausen developed the space grid system called MERO (acronym of ''MEngeringhausen ROhrbauweise'') in 1943 in Germany, thus initiating the use of space trusses in architecture. The commonly used method, still in use has individual tubular m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Internal Combustion Engine
An internal combustion engine (ICE or IC engine) is a heat engine in which the combustion of a fuel occurs with an oxidizer (usually air) in a combustion chamber that is an integral part of the working fluid flow circuit. In an internal combustion engine, the expansion of the high-temperature and high-pressure gases produced by combustion applies direct force to some component of the engine. The force is typically applied to pistons ( piston engine), turbine blades (gas turbine), a rotor (Wankel engine), or a nozzle ( jet engine). This force moves the component over a distance, transforming chemical energy into kinetic energy which is used to propel, move or power whatever the engine is attached to. This replaced the external combustion engine for applications where the weight or size of an engine was more important. The first commercially successful internal combustion engine was created by Étienne Lenoir around 1860, and the first modern internal combustion engine, known ...

Liquid Hydrogen
Liquid hydrogen (LH2 or LH2) is the liquid state of the element hydrogen. Hydrogen is found naturally in the molecular H2 form. To exist as a liquid, H2 must be cooled below its critical point of 33 K. However, for it to be in a fully liquid state at atmospheric pressure, H2 needs to be cooled to .IPTS-1968 iupac.org, accessed 2020-01-01 A common method of obtaining liquid hydrogen involves a compressor resembling a jet engine in both appearance and principle. Liquid hydrogen is typically used as a concentrated form of . Storing it as liquid takes less space than storing it as a gas at ...
