Bamboo Bicycle
Bamboo bicycles are pedal-and-chain-driven, human-powered, single-track vehicles that have two wheels attached to a bamboo frame. Because of its light weight, vibration damping, and sustainability, bamboo is slowly starting to be used in bicycle frame production, though the industry is still dominated by aluminium frames. History Bamboo bikes were first patented in England by the Bamboo Cycle Company and introduced to the general public on 26 April 1894. A US patent was applied for in 1895, by August Oberg and Andrew Gustafson, and granted in 1896. However, with the development of tougher industrial metals, such as steel and aluminium, large-scale usage of bamboo to build bicycles never happened. Though bicycles are a staple of human transportation, in both rural and urbanised areas, bamboo bicycles are not widely used. However, with the advent of the Green movement, bamboo is being used again, primarily for high-end racing and touring bicycles. Bamboo bikes are entering t ...

Columbia University
Columbia University (also known as Columbia, and officially as Columbia University in the City of New York) is a private research university in New York City. Established in 1754 as King's College on the grounds of Trinity Church in Manhattan, Columbia is the oldest institution of higher education in New York and the fifth-oldest institution of higher learning in the United States. It is one of nine colonial colleges founded prior to the Declaration of Independence. It is a member of the Ivy League. Columbia is ranked among the top universities in the world. Columbia was established by royal charter under George II of Great Britain. It was renamed Columbia College in 1784 following the American Revolution, and in 1787 was placed under a private board of trustees headed by former students Alexander Hamilton and John Jay. In 1896, the campus was moved to its current location in Morningside Heights and renamed Columbia University. Columbia scientists and scholars have ...

Appropriate Technology
Appropriate technology is a movement (and its manifestations) encompassing technological choice and application that is small-scale, affordable by locals, decentralized, labor-intensive, energy-efficient, environmentally sustainable, and locally autonomous. It was originally articulated as intermediate technology by the economist Ernst Friedrich "Fritz" Schumacher in his work ''Small Is Beautiful.'' Both Schumacher and many modern-day proponents of appropriate technology also emphasize the technology as people-centered. Appropriate technology has been used to address issues in a wide range of fields. Well-known examples of appropriate technology applications include: bike- and hand-powered water pumps (and other self-powered equipment), the universal nut sheller, self-contained solar lamps and streetlights, and passive solar building designs. Today appropriate technology is often developed using open source principles, which have led to ''open-source appropriate technology'' ( ...

Wooden Bicycle
A wooden bicycle is a bicycle constructed either mostly, or entirely from wood. Wood was the material used in the earliest bicycles, and is also used by modern builders, especially in balance bicycles for children. The wood can be either solid or laminate. History The first bicycles recorded, known variously as velocipedes, dandy horses, or hobby horses, were constructed from wood, starting in 1817. Modern Recent technological advances in adhesives and fabrication have made wood a feasible choice in the modern cycle world. Wooden bicycle frames are sometimes aided by steel or composite lugs to connect the wooden tubes or attach components. These frames can be made with plywood, hardwoods, or bamboo. HTech Bikes make Wooden bicycles. See also * Bamboo bicycle * Cardboard bicycle A cardboard bicycle is a bicycle composed mostly of cardboard. Only prototypes have been made . Reported benefits include low cost, and construction from recyclable and renewable materials. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SplinterBike
The SplinterBike is an invention by Michael Thompson. It is a 100% wooden bicycle which only uses glue to hold everything together. No bolts or screws were used. History On September 16, 2010, during the Tour of Britain, Michael Thompson (a veteran wood joiner) suggested to his friend James Tully (an amateur cyclist) that he could make a 100% wooden bicycle. James responded by saying that if Michael would build it, he would ride it. To consolidate these bold statements the two made a £1 bet. 100% Wooden Bicycle Land Speed Record On August 18, 2011 the two made a successful attempt to set the 100% Wooden Bicycle Land Speed Record with an average speed of 11.3 MPH (18.2 km/h). Because this was the first 100% wooden bicycle, all they needed was a successful run to measure the speed. Due to the use of a soft running track and mechanical failure, James was not able to drive the bike to higher speeds. SplinterBikeHʌɪbrɪd The Hʌɪbrɪd is a derivative of the original Splin ...

Chukudu
The chukudu (or chikudu, cbokoudou, tshukudu) is a two-wheeled handmade vehicle used in the east of the Democratic Republic of Congo. It is made of wood, and is used for transporting cargo. The chukudu generally has an angular frame, two small wheels (often of wood, sometimes wrapped with rubber), handlebars, and a pad for the operator to place their knee on while propelling the vehicle with their leg. On a descent, the rider stands on the deck like a kick scooter. On flat ground, the rider can put one knee on the deck and push the ground by the other foot like a knee scooter. Rubber mud flaps and shock absorber springs may be added. History Chukudus first appeared in the 1970s in North Kivu, during the difficult economic times under Mobutu Sese Seko. In 2008, chikudus were selling for US$100 with a cost of materials of nearly US$60. Similarly, in 2014 they cost $50 to $100 and were used to earn up to $10 per day, in an area where most people live on less than $2 per day. ...

Cardboard Bicycle
A cardboard bicycle is a bicycle composed mostly of cardboard. Only prototypes have been made . Reported benefits include low cost, and construction from recyclable and renewable materials. The low cost is also expected to act as a theft deterrent. Phil Bridge's prototype In 2008, Phil Bridge created a cardboard bicycle as part of a three-year degree course in Product Design at Sheffield Hallam University. It was intended to discourage theft, supports a rider up to , and is constructed from a structural cardboard called Hexacomb. It is waterproof, but is only expected to survive six months of constant use. The drivetrain and brakes are metal, as on a conventional bike, and it rolls on standard pneumatic tires. Izhar Gafni's prototype In 2012, Izhar Gafni, an Israeli mechanical engineer and cycling enthusiast, unveiled a prototype bicycle made almost entirely out of cardboard in his workshop in Moshav Ahituv. The components, including bike’s frame, wheels, handlebars and sad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bamboo Bicycle Tour Bikes
Bamboos are a diverse group of evergreen perennial flowering plants making up the subfamily Bambusoideae of the grass family Poaceae. Giant bamboos are the largest members of the grass family. The origin of the word "bamboo" is uncertain, but it probably comes from the Dutch or Portuguese language, which originally borrowed it from Malay or Kannada. In bamboo, as in other grasses, the internodal regions of the stem are usually hollow and the vascular bundles in the cross-section are scattered throughout the stem instead of in a cylindrical arrangement. The dicotyledonous woody xylem is also absent. The absence of secondary growth wood causes the stems of monocots, including the palms and large bamboos, to be columnar rather than tapering. Bamboos include some of the fastest-growing plants in the world, due to a unique rhizome-dependent system. Certain species of bamboo can grow within a 24-hour period, at a rate of almost an hour (equivalent to 1 mm every 90 s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Climate Change Mitigation
Climate change mitigation is action to limit climate change by reducing Greenhouse gas emissions, emissions of greenhouse gases or Carbon sink, removing those gases from the atmosphere. The recent rise in global average temperature is mostly caused by emissions from fossil fuels burning (coal, oil, and natural gas). Mitigation can reduce emissions by energy transition, transitioning to sustainable energy sources, energy conservation, conserving energy, and Efficient energy use, increasing efficiency. In addition, can be carbon dioxide removal, removed from the atmosphere by carbon sink, enlarging forests, Wetland restoration, restoring wetlands and using other natural and technical processes, which are grouped together under the term of carbon sequestration. Solar energy and wind power have the highest climate change mitigation potential at lowest cost compared to a range of other options. Variable availability of sunshine and wind is addressed by energy storage and improved elec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sustainable Growth
Sustainable development is an organizing principle for meeting human development goals while also sustaining the ability of natural systems to provide the natural resources and ecosystem services on which the economy and society depend. The desired result is a state of society where living conditions and resources are used to continue to meet human needs without undermining the integrity and stability of the natural system. Sustainable development was defined in the 1987 Brundtland Report as "Development that meets the needs of the present generation without compromising the ability of future generations to meet their own needs".United Nations General Assembly (1987''Report of the World Commission on Environment and Development: Our Common Future'' Transmitted to the General Assembly as an Annex to document A/42/427 – Development and International Co-operation: Environment. As the concept of sustainable development developed, it has shifted its focus more towards the economic de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
