Can motors in wheels spark electric car revolution? There may have been more alluring electric cars on display at this year's Tokyo Motor Show, but the beauty of this prototype lies in its performance. The SIM-LEI can travel 333 kilometers (more than 200 miles) on a single charge, say its Japanese creators SIM Drive, and it also boasts supercar-like acceleration -- 0 to 60 mph in just 4.8 seconds. The key to these remarkable statistics lies not, as you might expect, underneath the hood but in its wheels. Most electric vehicles house a single motor in the area vacated by the petrol engine, but the SIM-LEI has four motors, which fit in the hubs its wheels. Each one delivers 65 kilowatts, giving the car a total output of 260 kilowatts, compared with the 80 kilowatts of output available in, say, the Nissan Leaf. A 24.5 kWh battery sits below the floor along with inverters and controllers, which fit into a unique steel monocoque helping reduce weight, according to SIM Drive.
Estructura y enlaces químicos 40 Witty Campaign Posters for a Cause Non-profit organizations use posters to deliver a particular message. These help inform people about current issues, problems and even the possible consequences of their actions. With a sentence that contains strong words or images, these posters give more impact than common commercial posters. To give you an idea, here are 20 sample campaign posters to provoke your imagination. Wildlife is becoming harder to find in Vietnam. Winter. Who are the real monsters? When they speak, we listen. Shit is not a cool band. Say no to child labor. Can you treat yourself better than your doctor? Nothing we do will ever bring them back. Please don’t dive with white sharks. All under 25 who are sexually active should test for Chlamydia every year and avery time they change partner. For some people, life is that expensive. Preparing today reduces the consequences of disaster tomorrow. Two thirds of college students in Mississippi don’t smoke. Please clean up after your dog. One mistake is all it takes.
Nomenclatura de Compuestos Orgánicos Grime-fighting garments aim to purify air Polymer chemist Tony Ryan and fashion designer Helen Storey have joined forces to create clothing which can purify the air. Catalytic Clothing contains the same nanotechnology found in self-cleaning paints and glasses but applies it to clothes via a special fabric conditioner. A catalyst -- titanium dioxide -- applied during a normal home washing cycle breaks down harmful airborne pollutants when exposed to ultraviolet light. Ryan discovered that treated jeans were particularly good at absorbing pollution. Although only small amounts of pollution -- around two grams per 500-gram pair of jeans -- is removed from the air, Ryan and Storey say if the technology was worn widely then city pollution could be reduced. A short film featuring British model Erin O'Connor and music by rock group Radiohead was released in 2011 to promote the idea to the public. But together, Helen Storey and Tony Ryan are fusing style and substance to create clothes that purify the air we breathe.
Mecanismos de reacción Urban Omnibus | 50 Ideas for the New City The Omnibus is all about ideas. From the beginning, Urban Omnibus has been a showcase of good ideas for the future of cities, conceived in the public interest and tried and tested in the five boroughs of New York. So, we have decided to surface some of the ideas that have appeared on Urban Omnibus over the past two years and broadcast them around the city. In April 2011, we released a series of Idea Posters, pasted on fences, scaffolds and storefronts from Jamaica, Queens, to the Upper West Side of Manhattan, and many places in between. Below you will find 50 ideas for New York already explored on Urban Omnibus and a space for you to share your own.

Chemistry 51A Organic Chemistry - Fall 2009 - Download free content from UC Irvine Stuff: When Less Is More Today we use far fewer materials than we once did to get the same things done—a phenomenon known as “dematerialization.” But, paradoxically, this efficiency seems to drive up overall consumption. In Making the Modern World: Materials and Dematerialization, a deeply researched statistical profile of global material use, author Vaclav Smil lays out just how much stuff we need to live modern lives. We Make More with Less… Material intensity continues to fall dramatically. Energy intensity, the portion of the total energy supply required to produce a material, has also dropped markedly. A classic example of dematerialization is the computer. …But We Consume More Than Ever As efficiency rises, so does affordability, putting ever more products within reach of ever more consumers. in metric tons density = 0.85/ft³ What Does It All Add Up To?
