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.

Regenerative Carbon Dioxide Removal System(RCRS)
Eco-Cement Removes CO2 from the Air!
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.
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.

Greenhouse Gas Mitigation Project at the International University Bremen
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.
