Today’s so wide range of  very stylish things by any styles and color helps you  on the way to get a little from the earth but gives back  in countless ways. 

 

What’s the greenest car ever made?

So what’s the greenest car ever made? Well there may well be lots of cars and their manufactures that try to stake such a claim, of course.

But one car maker that deserves the accolade of having put together the greenest car of all is undoubtedly Honda.

“Why is that and what is the car in question” I hear you ask.

Easy; it’s the Honda Civic GX 4DR – and it is powered by natural gas.

But don’t think of this as some weird concept car that will never hit the showrooms. Not a bit of it in fact, for the Civic GX will be available from the Japanese manufacturer’s showrooms very soon across the United States.

The compressed natural gas powered Civic has already been market tested with governments, business top fleets and a few test retail markets and Honda has clearly decided the world is now ready for this greener than green car.

And it’s been around for quite some time. In fact, when the Civic GX was awarded the accolade of the Greenest Car of 2011 by the American Council for an Energy-Efficient Economy, it was the eighth year in a row that the car had been awarded the top prize.

Honda still only makes a few thousand of the cars each year, so it may be a while before it’s voted the best family car – but it may also be the future of green motoring once compressed natural gas becomes more widely available.

The Civic GX’s U.S. retail launch scheduled for later in 2011 comes as President Barack Obama has asked for the wider adoption of low emission cars – and says that all federal cars will need to run on alternative, hybrid or electric power by 2015.

Carbon Dioxide as a Chemical Building Block

Angewandte Chemie International Edition journal has published this year about developing a new copper catalyst that allows carbon dioxide to be converted into a variety of functionalized carboxylic acid derivatives—versatile synthetic chemicals by Japan researchers from RIKEN, greencarcongress.com reports.

Industry has used carbon dioxide as a chemical building block—in the manufacture of aspirin, for example—but its use is limited by the difficulty of breaking open its strong carbon-oxygen double bonds. Carbon compounds activated by lithium or magnesium are often needed to attack and incorporate carbon dioxide successfully, but these reagents are extremely reactive and quite hazardous on a large scale.

Zhaomin Hou, of RIKEN’s Advanced Science Institute, Wako, along with colleagues Takeshi Ohishi and Masayoshi Nishiura, has now developed a copper catalyst that helps the boron compounds for the carboxylation of aryl- and alkenylboronic esters with CO2.

This makes the reaction particularly useful for building complex molecules containing several different types of chemical group, something that would not be possible with the harsh lithium reagents.

Since CO2 is a renewable carbon resource, exploration of new reactions and catalysts for its efficient use is of great importance. One of our goals is to find a catalyst that can transform CO2 in exhaust gasses of automobile vehicles or chemical plants into useful materials.
