Graphene transcends disciplines
Interestingly, a few days ago The Economist published an article stating that “Bacteria may be the key to turning graphene into a semiconductor”, showing the potential of graphene in transcending disciplines in an effort to deliver superior products and services that are better for the ‘People, Profit and Planet’.
Given graphene’s extraordinary electrical conductivity properties, the possibility of making thin, flexible, semi-transparent graphene based electronics has existed in the public imagination for some time now. However, to date tests on graphene sheets showed that the electric current moves randomly and in all directions. Moreover, graphene does not have a bandgap – “a property needed to create the distinct “on” and “off” electronic states that transistors rely on to work, and which is induced in a material by disrupting the way its electrons are distributed”.
Tesla has open-sourced its patents on electric vehicle technology, according to a post on the company’s blog by CEO Elon Musk.
Musk explains that one of the company’s biggest goals is to move the entire electric vehicle market forward, which it can’t accomplish if it’s making it harder for others to enter the space:
Tesla Motors was created to accelerate the advent of sustainable transport. If we clear a path to the creation of compelling electric vehicles, but then lay intellectual property landmines behind us to inhibit others, we are acting in a manner contrary to that goal. Tesla will not initiate patent lawsuits against anyone who, in good faith, wants to use our technology.

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.

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…
The misconception that End of Life passenger car tires have no real value needs to be challenged and corrected. Today there are a few plants scattered around the world that crumb the material but it looks like the vast majority are incinerated as tire derived fuel (TDF). The approach to tire recycling thus far has been following the paths of least resistance with few technological strides of consequence. The primary problem in passenger car tires is the lower rubber recovery with a high fibre content,
A few days ago I saw an interesting article about a big rubber scrap (tire) rubber recycling operation being set up in Houston. Actually what was interesting was the way in which they justified the process and it’s viability, they were trying to compare the production of crumb as a superior recycling solution to the retreading of tires. The point I am making is that when you have been floating in a void long enough you forget where you come from and where your going becomes a function of the direction you happen to be pointed in. Now it sounds like a desperate attempt to find a positive spin to defend the indefensible where the audience has forgotten the plot, so no worries.
