pollution control gadget | |||||||||||||||||
One of the greatest pollutants in the world is automobile exhaust. Most of the internal combustion engines burn fuel inside the engine but unfortunately the particulate matter like carbon monoxide, lead etc are released into the atmosphere. Once they are released in the open, thepolluted air cannot be brought back and recycled clean.It is something like running after a helium baloon, afterits support ropes are cut. My idea is that every car manufacturer must fit in a pollution control gadget near thecar's exhaust pipe, which will trap the particulate matterand release only hot air. I feel this can be made possibleusing simple technology. When polluted water can be rendered pure by charcoal filters, membrane filters, resin filters, candles etc, why not automobile manufacturers adopt the same technique in containing the particulate matterwithin the car and later disposing of the collected materialin a safe manner. Once this idea becomes a success, thegovernments throughout the world can make it mandatory for thecar manufacturers to instal a pollution control gadget ineach and every car they manufacture.

Cattimanchi, I'm pretty certain that carbon monoxide and nitrogen oxides are pollutants that leave the exhaust pipe as gases, not as particulate matter. In the USA we burn unleaded fuel (except aircraft) and again, even in planes, I think the lead leaves the system vaporized.
So a 'filter' wouldn't be able to remove or trap any of these particles. It is true that diesel engines and worn-cars that are burning oil do produce particulates, but any filter to trap them would quickly be filled, thus it would require to be changed almost hourly. In one hour, a 2.0l engine at 4000rpm will run 240,000 liters of air through it. I just don't see it as reasonable to change filters and then they become a disposal hazard--the particulates are probably less dangerous dumped into the air than captured in a filter.
Also, our environment is very good at removing particulates from the air by means of rain.
As for your government mandate, cars already are required to be built with a catalytic converter (in USA anyway), which heats up and catalyzes to promote complete burning, but doesn't 'filter.'
At some point, we will most likely start producing mass amounts of electrical power using solar arrays. Electricity can be used to produce large amounts of hydrogen to be used as fuel. Engines already exist that can power vehicles for transportation. GM has spent billions of dollars developing the "Skateboard", which is a rolling chassis which uses hydrogen as its primary fuel. They pop whatever body on it suits the market.
Hydrogen when burned in an engine helps clean up the atmosphere and greater than 99% of the exhaust is water. Some byproducts are created, but far below what is currently produced.
I would be interested if anyone has created a home-built hydrogen generator that runs off of electricity. A windmill, solar arrays, even a small hydroelectric dam, could potentially provide anyone with the power they need in a form that is easily harnessed.
Hrench is correct.
In the next 10 to 20 years, gasoline powered cars are going to be largely displaced by electric cars. Some may use hydrogen, but batteries are probably going to be the mainstay.
