Ionisers and pollution
17th Aug 1999 Srinath Srinivasa @geocities.com
Hello all, After having to catch up with the real world for some time, I am back to discussing some ideas posted on "Ideas for India" (http://www.indiapolicy.org/ifi) database. Recently I read a news item that in Bangalore auto rickshaws have been advised to switch over to LPG engines before 2000. Can anyone provide more details on it? A while back, we had an entry in the IfI database by Anil Kelkar, which said that CNG is better and safer than LPG. And that taxis in Mumbai are running on CNG already. Anyone would like to comment or elaborate on these issues? Recently I had read about an article which talked about new traffic police kiosks in the midst of traffic which were being designed with ionizers inside them so as to reduce the pollution levels inside the kiosks. I was wondering... how would it be if on most busy roads of our cities ionizers were installed at regular intervals (powered by say, solar batteries) to reduce the amount of suspended pollutants in the air? I am just a layman to this topic thinking wild ideas-- anyone would like to comment on this in a more objective and informed fashion? Looking forward to some more of your ideas. Warm Regards Srinath

Hi, 1. ionizers, not much good. I had one at home and all it did was to charge steel tables. Whats CNG? Pranav

Dear Srinath,
Did you see the article "How safe is LPG fuel for motor vehicles?" in
The
Hindu (date : 19-8-99; page : 21)? This article is written by Mr S.
Sivaraman, Manager, Fire & Safety (Retd.), IOC Limited, Southern Region.
LPG characteristics, advantages and disadvantages of using LPG as motor
fuel; fire accident scenario when LPG is used as fuel are discussed.

I am > just a layman to Would'nt work. Ionizers have the function of attracting dust, which ends up accumulated in the periphery of the device. If these devices were used in the manner you describe, they would simply displace dust and suspended pollutants, not get rid of them. No solution to pollution, AFAIK. Thank you!

Hi Pranav and others, Oops! I thought so-- about ionizers charging up metallic surfaces nearby. Also I guess they can only coagulate floating dust, and not the "real" pollutants like noxious gasses.. Any other ideas? I'd be glad to place them in the database for perusal by others. BTW, CNG is compressed natural gas. Best Srinath

> No solution to pollution, AFAIK. Sounds ominous! No solution to pollution, that is. Especially since pollution kills!! I am not sure... ionizers would attract dust if the ionized gas stay inside/nearby the ionizers. But what if the ionizers are designed to ionize the air around them which is then blown away from the ionizers so as to let free ions into the atmosphere? Of course, much more than these "remedial" measures, a more effective solution is a "preventive" measure-- preventing pollution from vehicles/industry/people, etc. But since there is already so much of the disease found, we also require some of the remedial measures... -srinath

Hi, Where would you blow the air too? One effective solution seems to be hydrogen power. A bit explosive but should do the job. Pranav

Hi! > Where would you blow the air too? Up. Some cities actually do this as a quick fix measure. > One effective solution seems to be hydrogen power. A bit explosive but > should do the job. We do not (yet) have technology which synthesise hydrogen fuel for mainstream use - the logical solution to this and many other problems is to reduce consumption to the point where our environment is self sustaining in all ways. Which would mean a small change is our way of life and a majour change in the way of life of certain people whose ways we tend to mimic. Like I said earlier, no solution to pollution. BTW, I heard this phrase in an ad on the TV.... Thank you!

Some cities actually do this as a quick fix measure. > What I meant was, since ionizers ionize the air around them, they tend to attract dust towards them; but if there were some technique (like in air conditioners, for example; or more correctly, like in air coolers), that the ionized air is blown away from the ionizer, free ions would get scattered in the atmosphere and hence does not attract dust towards them. > > We do not (yet) have technology which synthesise hydrogen fuel for = > mainstream use - the logical solution to this and many other problems = > is to reduce consumption to the point where our environment is self = > sustaining in all ways. Well yes. We should be looking towards alternative less polluting fuels. And also we should be looking at ways by which the real pollutants in the air can be removed-- like toxic gasses; rather than dust. But the fact remains that dust also contributes much to pollution and related diseases like asthma (in Bangalore, for example, the usually dusty, dry air coupled with pollution is the major cause of lung problems). I think, any solution for a problem of this proportion should have a multi-pronged strategy-- addressing the problem from many different ends simultaneously.

Hi, See your point. Interesting. However, dust would be attracted to those free ions and I doubt that will help. One possible solution to the polution is to improve our telephone lines, get e-commerce laws in place and conduct business from home. Mind you this is just slightly more possible than changing life styles; however, if the telecom sector is privatised, then we may see some steps in this direction. Pranav
