Submission + - Concrete That Purifies The Air (gizmag.com)

fergus07 writes: Although much of the focus of pollution from automobiles centers on carbon emissions, there are other airborne nasties spewing from the tailpipes of fossil fuel-powered vehicles. These include nitrogen oxides (NOx). In the form of nitrogen dioxide it reacts with chemicals produced by sunlight to form nitric acid – a major constituent of acid rain – and also reacts with sunlight, leading to the formation of ozone and smog. Everyone is exposed to small amounts of nitrogen oxides in ambient air, but exposure to higher amounts, in areas of heavy traffic for example, can damage respiratory airways. Testing has shown that surfacing roads with air purifying concrete could make a big contribution to local air purity by reducing the concentration of nitrogen oxides by 25 to 45 percent.

Chewing gum is *the* single thing I truly despise in our free societies. It is ridiculously cheap, ubiquitous, popular - and more stable in the environment than granite. People chew that stuff all the time and spit it everywhere - all floors, streets, corners, sidewalks of all cities are riddled with that decades-old, positively eternal chewed chewing gum.

Just look at the streets on a busy intersection: thousands of flattened chewing gum remains, outlasting the tarmac they are embedded in by decades.

Sometimes when I look down on the city floor for some reason and notice the gum, I have a hard time regaining the faith in personal freedom, pushing back the urge to cry for Singaporean laws against that filth.

Honestly: what part of individual freedom demands that people can spit this stuff everywhere?

Solution? We build our roads out of chewing gum! Problem solved.

The Eee and its ilk have shown that people are willing to buy Windowsless boxes, which is an affront to Microsoft's business model. You have to wonder if Midori is a "plan B" to allow them to continue to get revenue from Linux users. Alan, Bob and Clarence may well be willing to pay $10 a month for "Windows access" on their Eees if it lets them use Office, and this way Microsoft have a guaranteed revenue stream whatever OS people actually buy with their machine. Especially if it's agressively marketed and bundled.

That may be all well for Alan, Bob and Clarence; but I'm sure ol' Steve has a thing or two to say about that.
