Artificial hips glide on graphite

22 December 2011
Metal-on metal hip replacements are lubricated by a layer of graphite, say scientists in the US. And this graphitic layer may be the product of proteins ground up the implant itself. This knowledge could help the design of new implants but also raises important questions about the action of the graphite in the body.

Over 50,000 hip replacements are performed each year in the UK and in the US that number is over 200,000. But although surgeons are moving towards low wearing metal-on-metal joints, no one is precisely sure why the two metal pieces slide so well. Although it is known there is a layer that affects the friction, lubrication and wear of the two surfaces, known as a tribological layer, until now no-one has examined its composition.

Tesla Comes Through With Sub-$50,000 Model S, Mostly

Hannah Elliott, Forbes Staff

The Tesla Model S

Tesla today announced official pricing for its four-door electric sedan: $49,900 for a base Model S after a $7,500 federal tax credit.

The announcement comes after months of Tesla founder Elon Musk promising to deliver his first four-door electric car for around $50,000. (Tesla started selling its battery-powered $109,000 Roadsters in 2008.)

Of course, higher performing versions of the seven-passenger sedan will cost more: $59,900 for a 60 kWh (230-mile-range) model and $69,900 for an 85 kWh (300-mile-range) model. The 85 kWh performance Model S, which comes with additional equipment like Nappa leather interior and performance wheels, will cost $79,900 after federal tax rebates. Musk says it will go 0-60mph in 4.4 seconds.  More…….

China opens doors of state-run companies to world’s top talent

By Vivek Wadhwa, Wednesday, November 16, 3:48 AM

The top talent in countries around the world have a new suitor: the Chinese government.

China has a severe shortage of skilled talent and, in a policy reversal, has decided to open its doors to talent from around the world. This could mean that the brilliant NASA scientists the U.S. laid off, could find new employment — and a new home — in Shanghai or Beijing.

Chinese research labs have long had difficulty recruiting qualified workers to perform necessary research and development, and its corporations struggle to find competent managers. The situation will likely get worse as China’s high-tech industries grow and it increases its national R&D spending from the present 1.62 percent of GDP, according to the Chinese government, to the planned 2.5 percent by 2020. China’s President Hu Jintao, in May 2010, declared talent development a national priority in order to fill the void. The goal is to dramatically increase the education level of China’s workforce and to build an innovation economy.

LED Technology in Globe Bulb Applications

LED’s Poised to Take Over CFL’s

According to experts in the LED industry, the LED lighting market is strong and constantly changing as the technology evolves. Only one year ago some bulbs would have cost almost double what they are priced today. Since LED technology is advancing so rapidly, newer LED bulbs are coming out brighter and cheaper than they were before. LED lighting has continued to gain market share in 2011 as governments around the world have adopted policies in favor of LED lighting because of growing environmental concerns. LED light bulbs for the home are one of the easiest ways to save up to 90% on your home lighting bills if you are switching from incandescent bulbs.

Hyundai Making 2,000 Hydrogen Fuel Cell Electric Vehicles

On September 13, 2011, in Blog, by John Addison      

           

The most popular way to extend the range of an electric vehicle is to add a small gasoline engine coupled with a generator as done in the Chevrolet Volt plug-in hybrid. The most popular way to extend the range of an electric bus is to add a fuel cell that generates added electrons. During the Winter Olympics, 100,000 riders were transported up Whistler’s 12 percent grades on 20 hydrogen fuel cell electric buses. Now SUVs made by Hyundai-Kai, General Motors and Toyota are also testing Fuel Cell Electric Vehicles (FCEV). More…

What I learned from Steve Jobs

By: Guy Kawasaki

OCTOBER 8, 2011

Guy Kawasaki

guest column.  Many people have explained what one can learn from Steve Jobs. But few, if any, of these people have been inside the tent and experienced first hand what it was like to work with him. I don’t want any lessons to be lost or forgotten, so here is my list of the top 12 lessons I learned from Steve Jobs.

1. Experts are clueless Experts—journalists, analysts, consultants, bankers, and gurus can’t “do” so they “advise.” They can tell you what is wrong with your product, but they cannot make a great one. They can tell you how to sell something, but they cannot sell it themselves. They can tell you how to create great teams, but they only manage a secretary. For example, the experts told us that the two biggest shortcomings of Macintosh in the mid 1980s were the lack of a daisy-wheel printer driver and Lotus 1-2-3; another advice gem from the experts was to buy Compaq. Hear what experts say, but don’t always listen to them.

Air Pollution Loophole Puts Communities in Danger from Unregulated Waste Burning

Groups sue U.S. EPA to close loophole, protect public health and the environment

June 16, 2011

Washington, D.C.  —

Burning Solid Waste

Earthjustice, on behalf of Sierra Club, Montanans Against Toxic Burning, Huron Environmental Activist League and Downwinders at Risk filed a lawsuit in federal court today that challenges an egregious air pollution loophole supported by the U.S. Environmental Protection Agency. The suit disputes the Obama EPA’s unprecedented assertion that burning industrial solid waste as a fuel—akin to coal or natural gas—is a form of recycling, and therefore not subject to key provisions of the Clean Air Act that protect people from the harmful air emissions that result. Industry groups have pressed previous administrations long and hard for just such a favor, but the Obama administration is the first to acquiesce so broadly to their demands.

End Of Life Tire Recycling – New Approach

Scrap Tires - Solid Waste Managment

The ultimate model which addresses all possible aspects of environmental sustainability in rubber recycling is still Devulcanization but should start right from the collection of tires. This means the starting point should be at the tire collection centers or in the US possibly at the landfills. Here we are not talking about solid waste management anymore but effectively managing a vital raw material in process.

Addressed properly the tires would not be dumped in the open but would be separated out between passenger car and commercial vehicle (truck) tires, making it possible to split up the feedstock into types ie. Mostly Natural Rubber (80/20) from Commercial vehicle tires and Mostly Synthetic (60/40) for passenger car tires. This important step also makes it possible to shoe horn in a step which could see the eventual removal of the Butyl inner liners by grinding or peeling off. The resultant by-products would be butyl scrap feedstock and butyl free scrap tire feedstock, an interesting and very significant change to the current situation.

SUSTAINABILITY

MOVE WITH PURPOSE, COMMITMENT

Gopi Sekhar, CEO Sekhar Research Innovations

We live in a world that has taken its bounty and blessings entirely for granted for a very long time. The most basic levels of reciprocation to maintain balance in our environment were ignored and we might have pillaged our way to a point of no return. The only option left beyond packing up and leaving mother earth is to do away with polluting processes and address sustainability in any and all our activities.

The challenge before us is to make sustainable activity in the form of greentech and applications related to the improvements in efficiency and energy conservancy, cost effective and profitable. Fortunately, we do have solutions that can go a long way towards mitigation. Some challenges require us to invent, others called for applying common sense and using existing Smart solutions.
