Advanced Engineering Tech - purifying air using engine power

i got an idea of purifying air using engine power. i saw around 2 weeks ago that there was available electrical air purifiers (here in Kuwait) that purify air from dirts, maybe carbon and such it was like $304. i said to my self a few days ago why they don't invent a device that has its own electricity generator (its own pulley just similar to the alternator) and uses this electrical power to power the air purifier in the car using the engine as part of its accesories just like the alternator, PS, AC compressor...etc.

i'm sure with years this device will be much more efficient than its first time to the public.

what do you think? this idea will sure help the OZON problem and the pollution problem.

Many purifiers actually generate unhealthy amounts
of ozone (the electrostatic ones). They will remove
particulates but not gaseous neutral molecules. The
airflow moved is minimal (otherwise all the crud would
just blow right past the plates).

so you meant that only small amount of the air passing through the purifier will get purified and the rest will get away without purifying? correct?

what is the unhealthy OZONE? this is the first time i heard of.

i also thought in the past about a device that is able to seperate gases from O2, carbon and such, sure this a completly chemical reaction, so what i want is a chemical device that can seperate O2 from other harmful gases and particles, is this implementalble?

ozone is O3, as opposed to normal oxygen which is O2.
ozone naturally occurs at ground level after thunderstorms, you can sometimes smell it and in high concentrations can give you headaches and make you queezy. So you would not want to generate O3 from an air purifier in a small enclosed space, it would be unhealthy. What happens with electrostatic air purifiers is first, they work by passing air over plates so it's the square area of the plates that determines how much volume or CFM of air it can "purify". So they purify very little actually, and second because they purify by electrical/electrostatic means they create O3. for this type of application the most practical and cost effective "purifier" is simply a filter. Purify is a subjective word

Another cool thing is O3 in high amounts kills pretty much everything :) I've seen O3 generators put inside cars to remove odors.

It also likes to destroy rubber.

thanks for the info. now i got some new info and i begun to understand more about air purifiers. actualy i didn't know that air purifiers use electricity to generate O3 the ozone. what i mean't in my thinking that using some kind of chemical reaction in some way to seperate carbon and other harmful materials from O2 and generate O2 to the atmosphere.

so, are you saying that the way now to catch some of the carbon in the air is using a filter? how efficient is this way? and what is the amount of carbon it can catch? will the air be efficeintly purified that way?

thanks.

i think you may be asking your questions in the wrong place, most people here are experts in spewing carbon (i.e. hydrocarbons) into the air, not catching them :burn:

I think you need to better define what you are trying to filter, what are your contaminants. Yes a good way to purify air, or filter air, is with a simple filter. And there are various designs and levels of filtration. A HEPA filter comes to mind- (high efficiency particulate air) remove at least 99.97% of airborne particles 0.3 micrometers (µm) in diameter; http://en.wikipedia.org/wiki/HEPA.
This is a particle filter. You mentioned catching some of the carbon in the air, not sure what you mean by that. Now if you want to catch other things like gases or odors then there are carbon charcoal type filters, filters that do these are more of a chemical filter than a mechanical filter.

i'm thinking about air pollution and if there is a solution for it. so until now there is only these mechanical filters and chemical filters to catch carbons and such gases and contaminants. i was thinking of about how if we can seperate O2 from CO2, CO and every other harmful gases to get more O2. is there a way to seperate these gases to get O2?

i know plants can take CO2 and output O2, so this might give an idea.
