On the road to cleaner air with air-purifying concrete

By Darren Quick

00:42 July 7, 2010

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.
( . . . )

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.

Re:  Auto pollution.

Nitrous Oxide can be removed from all combustion processes by using Stainless Steel wool in the exhaust manifold of a car, for instance. It must get red hot in order to work.

Source:  The Amercian Hydrogen Assoc . This has been know for some years.

Why is the Society not promoting this fact? Why is it not general knowledge?

Also running the exhaust gases through lime water will remove most other nasties.

Regards John Mcmabus

@John M: one big problem with catalytic exhaust is that it *must* be red-hot for it to work.

Until we change our driving habits, it’s not that effective, as lots of people drive for short distances, thus not giving it enough time to be effective.

Plus, even in areas where it’s enforced, you have lots of cheaters, and guys who only replace it after they’ve been fined, or make arrangements with local mechanics…

unless you somehow magically transform all bad people into good persons, this concrete is still a good idea…

I’m going to stop and try a video thing with some files and maybe make a bit of music to go with it or an explanation made as I go along or something. Then, I’m off to find the business elements from my files to at least start constructing the first of several business plans for the things I have sitting around which have been needing to made into appropriate businesses.

I will put some more about this subject matter on the noxer blocks and other pollution dissolving cements, concrete, paints and other methods that have been found now – maybe over the next few days, maybe tomorrow. Also, I noticed some things on the news worth exploring – from UPI, ABC local Atlanta news, CNN and bloomberg on cable. So, first to do a video thing on the Cricket House Studios channel at Livestream and then work on the rest of the list above (and finish folding the clothes to put away after washing them yesterday . . . )
