Experienced in staging renewable energy events, the company is now scouring the country for a suitable location, as the cars will be racing not on a track, but through city streets.The low noise output of the vehicle makes it well suited to an urban street race, and because the event is not limited to a track, cities around the country can take turns to play host.Green motoring technology Motor racing has long been a platform for the development of new technologies, which in turn lead to these technological advancements filtering down to consumers.With the world market for electric vehicles expected to reach 10% of total production by 2020, Formulec is looking to the future. The company intends to contribute to the acceleration of green automotive research, and help improve the efficiency of electric vehicles.South Africa, as an EF01 host, will take its place at the forefront of renewable energy technology innovations. The country has already made its mark in this field with the development of the all-electric Joule, which is currently between the prototype and full production stages. It’s expected to debut on local showroom floors in 2014.As concern grows over climate change and the planet’s oil reserves, the focus is shifting to finding new sustainable transport solutions such as electric vehicles, as manufacturers gradually look to phase out fossil fuel engines. With no exhaust, the electric car is eco-friendly and quiet, and is an attractive alternative in large cities where commuters grapple with the problem of increasing traffic.The EF01 series will open up opportunities for innovators in the eco-energy industry to publicly showcase their technologies in a festival atmosphere at each event.High performance Designed to equal the performance of its cousin, the combustion-driven Formula Three car, the single-seater EF01 is more than capable. The fastest racing electric car in the world accelerates from 0-100kpm in a blistering time of under three seconds and reaches a top speed of around 260 km/h.The two-wheel-drive Formula Three cars have 2 000cc four-cylinder engines. Formula Three is seen as one step below Formula One, with fine drivers such as Ayrton Senna, Michael Schumacher, David Coulthard, Ralf Schumacher, and Takuma Sato coming through the lower ranks to achieve success in the high-powered racing championship.The EF01 took 30 months to come to life. In developing the EF01, Formulec and its partner, engineering specialist Segula Matra Technologies, have brought with a host of motoring experts on board, including Siemens, which is responsible for the car’s two electric motors; Michelin, which has adapted new energy-saving tyres to the power of the EF01 motors; Oz, which provided the rims; Hewland, which developed a unique transmission system for the EF01; and Saft, which developed the car’s special lithium ion battery system.The bodywork has been shaped by, among others, the highly experienced Mercedes GP Petronas Formula One team.The EF01 first took to the track in September 2010 at Magny-Cours in France, followed soon after by an outing on the Bugatti track at Le Mans. Its battery life allows it to race for up to 25 minutes, says Formulec, depending on the track, with a qualifying time similar to that of the Formula Three vehicle.The car debuted at the Paris Motor Show in October 2010.last_img read more

first_imgThe weathering of wood is very different from decay; weathering is breakdown at the surface only. While there are a number of forces that contribute to weathering of wood—moisture, temperature, abrasion by wind-borne particles, air pollution—it’s the narrow band of high-energy ultraviolet light in sunlight that is the dominant force (see Image #1).What bare wood looks like when cut or milledImage #2 is an electron micrograph of unweathered wood. You can see how robust the cells appear; we are primarily looking at the lignin in the wood, the chief component of wood that gives it its structure. Wood treatments, particularly primer paints, are formulated to bond and bind to unweathered wood.What weathered wood looks like after UV degradationImage #3 is an electron micrograph of weathered wood, wood exposed to sunlight for a month. You can see how the wood cell structure has deteriorated significantly. Remember this is a surface phenomenon that does not affect the structural integrity of the wood. But this surface degradation has significant impact on how well treatments, such as paint primer, bond and bind to the surface of the weathered wood.A paint primer testResearchers and paint manufacturers have tested the effect of UV degradation on the bonding and binding of finishes to bare wood. It’s dramatic; just a couple or so days of direct sunlight can degrade the wood enough to reduce the quality of the primer bond to the bare wood. Image #4 shows testing done by Sam Williams of the Forest Product Laboratory (FPL). The test boards show that the longer the exposure of bare wood to sunlight, the poorer the bond and shorter the service life of the paint. His conclusion: “Smooth-planed lumber [that is, siding and trim] must be painted promptly during construction.”Lesson learnedPrime or initially treat bare exterior wood as soon as possible. Ideally, go with factory-primed exterior wood cladding components. It doesn’t make sense to pay good money for exterior wood components and not take the time, right away, to protect them from the sun. And in areas of the country with the highest UV index (mostly the southwest and locations at altitude), it’s even more important to get that sunscreen on your naked wood!For more detailed information on the weathering of wood see these resources from the Forest Products Lab:1.
