LONGER LIFE LINKED WITH AIR POLLUTION CUTS, March 16
Harvard University scientists say they've found a link between people living longer and cities reducing the amount of fine particulate matter in the air.
Full story at http://www.physorg.com/news11813.html


is it possible to invent a filter for cars and aeroplanes, to filter out all fine particulate matter and by with the same filter catch all the usefull gases such as co2 ?

this way, reduce the global warming ... and help citiziens enjoy breathing more.

with the co2, bioreactors of algae could be fed, and the grown algae could then be used as animal food or could be processed into biodiesel.

according to this image at

the amount of oil from marine microalgae could be upto 35 000 l per hectare of land.

or... if not directly at the car, there are working systems known how to capture the co2 in the air and then use it for growing the algae


it seems to me very possible to do it ... right now ... just put all this technologies together and promote the car/aeroplane filter or the air filtering on a wide scale

New Clas s of Materials Can Store Vast Amounts of Carbon Dioxide
(...)
The star performer in Yaghi's cast of MOFs is one dubbed MOF-177, which sops up 140 percent of its weight in CO2 at room temperature and reasonable pressure (32 bar).
Put another way, "if you have a tank filled with MOFs, you can store in that tank as much carbon dioxide as would be stored in nine tanks that do not contain MOFs," Yaghi said. By comparison, a tank filled with porous carbon---one of the current state-of-the-art materials for capturing CO2 in power plant flues---would hold only four tanks worth of CO2.

Eco-Cement Removes CO2 from the Air!

http://www.tececo.com/sustainability.biomimicry.php

Biomimicry
In eco-cement blocks concretes and and mortars the binder is carbonate and the aggregates are preferably wastes. Sequestering carbon in magnesium binders and aggregates in the built environment mimics nature in that carbon is used in the homes or skeletal structures of most plants and animals.

http://www.tececo.com/sustainability.tececo_kiln.php

Using TecEco kiln technology it is possible to run a sequestration cycle based on the magnesium thermodynamic cycle whereby MgO scrubbs CO2 out of the air and becomes a carbonate and then what is not used in the built environment as bricks, blocks pavers etc. is re-calcined back to MgO in a closed system so no CO2 is returned to the atmosphere. The kiln has the following features:

* Grinds and calcines at the same time.
* Runs 25% to 30% more efficiency.
* Can be powered by solar energy or waste heat.
* Brings mineral sequestration and geological sequestration together.
* Captures CO2 for bottling and sale to the oil industry (geological sequestration).
* The products – CaO &/or MgO can be used to sequester more CO2 and then be re-calcined. This cycle can then be repeated.
* Suitable for making reactive reactive MgO.

Ohio University photobioreactors use sunlight to sequestor carbon from coal-fired power plans as they produce biomas. The Ohio University reactor will ultimately remove the carbon generated by the production of about 125 MW of electricity in a coal fired plan.
This system is expected to sequester carbon at a cost of $5-8 per ton surpas sing the U.S. Department of Energy's goal of $10 per ton. It will also reduce the space required by a factor of 10 or more, when compared to raceway cultivators.

http://web.mit.edu/newsoffice/2004/algae.htmlGreenFuel has installed 30 bioreactors on the roof of the Cogen plant, MIT's main steam, chilled water and electrical power plant. Each bioreactor is composed of polycarbonate tubing in the shape of a triangle; the tubes are clear, to allow sunlight in. Inside each tube, exhaust will mix with the algae. Thanks to photosynthesis, the algae will consume the CO2 and pollutants, grow in volume and give off oxygen and nitrogen. The algae will be harvested and dried into the charcoal-like solid to be reused as fuel. In a later phase Cogen heat may be used for the drying process.

BERZIN: I'll tell you what the problem is. You have to produce algae in a cost that will be cheap enough to compete with fossil fuels. Then you think, wait a minute, what does this technology need? It needs land, and you need water, and you need CO2. So, CO2 is not an issue. You're located next to a CO2 generating facility. Water, you get to use any quality of water. Treated sewage water, brackish water, ocean water, any water available. The third thing is, the land, usually near these big power plants, no one wants to live. It's non-fertile land, nothing grows there even. So, you don't really compete with agriculture. So, how realistic this is? We believe it is realistic.
GELLERMAN: Isaac Berzin...founder and chief technology officer of Greenfuel Technologies Corp. You can see for yourself if algae are pond scum or planet savers.

I think the problem may not be how to filter out CO2 from car exaust fumes, but where to store the filtered CO2.

An average car procudes various tons of CO2 per year ( about 20 kilos per day on a small sized car, 40 kilos or more on an SUV ).

Even if you can filter them out, where would you store them?

Is it possible to create a way for the filtered CO2 to be processed in a way that it can be broken down to it's main two components: Oxygen and Carbon. and these components can inturn be used to power the vehicle in some way?

Or, the oxygen can be released in the atmosphere and the carbon reused in the vehicle somehow. It would be like a prepetual system where the emissions can be reprocessed into something that is used by the car and as the car in use emits CO2, that is inturned used again. Like circle.

I know very little about physics but an excited about the process of creating efficency. I just want to know if it's possibleand if so, would it be cost effective?

We don't want to carry around CO2 capture devices on engines that move around (planes, cars, etc.) because CO2 is much, much heavier than fuel and thus would drop efficiency horribly. Directly capturing CO2 from stationary sources (coal plants, etc.) is much more viable

Regarding the OP title, I was sad to find out how much more diesel pollutes vs. gasoline. The CO2 contribution might be similar, but the pollutants that directly hurt people is much higher. sad.gif

"A new technology that can capture the carbon emissions from your car is about to be unveiled to the world for the first time in Liverpool at the Green-Car-Guide Live! 2008.

Origo Industries has developed a system that captures the CO2 from your vehicle’s engine and then allows you to turn these emissions into fuel at your own home to re-power your car. The same fuel could also be used to power your house.

The system uses a revolutionary new approach where CO2 is regenerated through algae in a home unit, allowing the user to produce bio-oil (up to 2500 litres per year tax-free)."

i am sorry to not find any report of what happened at their live show, anyone knows more ?

I read a study where 90% of CO2 emissions from vehicles come within the first 20 feet of driving. blink.gif Yes, a disposable filter would be a beautiful thing attached to your tailpipe. smile.gif
