water and CO2 captured from the atmosphere
دى تبقى معجزة سيارات تستعمل CO2 الذى فى الجو بدلا من تلويث الجو به شكرا على المعلومة ولكن متى تطبق هذه الابتكارات

This is a very good idea. If taking the carbon we scrub from the flue's of coal and other energy plants we can solve two problems at once; we can slow down or even stop our pollution of the atmosphere and we can also create a fuel from this. This isn't a long term solution since the sources that the CO2 is coming from aren't renewable, but it's a very good short term solution until we have the technology to create a long term solution.

هما بيقولوا فى التقرير ان دى تقنية للبطاريات على اساس تخزين الشحن الذاتى ولا ايه راءى سيادتك ؟؟!اما عن اسالة الوقودbiofuels فقد تمت التجارب فعليا لدى بى ام دبليو واودى ومرسيدس والسيارات تبلى بلاء حسنا!

CO2 from Air for Fuel
There are several other CO2 from air research and commercial projects, some with direct conversion to fuel. There is overlap with the Lackner and European project described above.

1. Department of Energy's Sandia National Laboratories uses concentrated solar energy to chemically 'reenergize' CO2 into carbon monoxide in its 'Sunshine to Petrol' project. The CO is then used to synthesize a liquid combustible fuel like gasoline, diesel, and jet fuel. Researchers have already shown proof of concept for their technique. They are now completing a prototype device, called the Counter Rotating Ring Receiver Reactor Recuperator, which uses solar energy to break down CO2. While this isn't going to produce fuel commercially tomorrow – Sandia researchers say it could be 15 or 20 years before that happens – it is an exciting and important move forward.

2. Los Alamos National Laboratory's 'Green Freedom' technology would extract carbon dioxide from the atmosphere and turn it into fuels. Air would be blown over a liquid potassium carbonate liquid to absorb the CO2, and then the CO2 would be extracted from the liquid and electrochemically separated to turn it into fuel. The Green Freedom system could use existing cooling towers, like those at nuclear power plants, which would eliminate the need to build additional structures for processing large volumes of air.

3. CO2-to-fuel technology at Carbon Sciences technology is based on natural organic chemistry processes that occur in all living organisms. Here, carbon atoms extracted from CO2 and hydrogen atoms extracted from H2O are combined, creating hydrocarbon molecules using biocatalysts and small amounts of energy. Using advanced nano-engineered biocatalysts, the technology lends itself to very large industrial scale production. The company plans to demonstrate the technology within the next several months with a prototype that can convert a stream of CO2 into an immediately flammable liquid fuel.

4. In the ELCAT (Electrocatalytic gas-phase conversion of CO2 in confined Catalysts) project, researchers at several European universities have shown the feasibility of gas-phase CO2 conversion in a catalytic process that recycles carbon dioxide into liquid hydrocarbons and alcohols. The technology, which has the potential to cut global CO2 emissions by 5 percent, could be ready for application in a decade.

5. The University of Nottingham's Centre for Innovation in Carbon Capture and Storage in the UK has successfully completed transforming CO2 into natural gas. The CICCS group has replicated the process in plants, capturing CO2, water, and solar light and transforming it into carbohydrates to create methane.

Researchers at the Georgia Institute of Technology have developed a strategy to capture, store and eventually recycle carbon from vehicles to prevent the pollutant from finding its way from a car tailpipe into the atmosphere. They envision a zero emissions car, and a transportation system completely free of fossil fuels but powered by renewables instead. They compared their concept with other proposed mobility concepts, in particular electric cars and hydrogen vehicles, and found it to have a range of advantages.

Technologies to capture carbon dioxide emissions from large-scale sources such as power plants have recently gained some impressive scientific ground, but nearly two-thirds of global carbon emissions are created by much smaller polluters — automobiles, transportation vehicles and distributed industrial power generation applications (e.g., diesel power generators).

The Georgia Tech team’s goal is to create a sustainable transportation system that uses a liquid fuel and traps the carbon emission in the vehicle for later processing at a fueling station. The carbon would then be shuttled back to a processing plant where it could be transformed into liquid fuel. Currently, Georgia Tech researchers are developing a fuel processing device to separate the carbon and store it in the vehicle in liquid form.

The concept is outlined in a paper in Energy Conversion and Management. The research was funded by NASA, the U.S. Department of Defense NDSEG Fellowship Program and Georgia Tech’s CEO (Creating Energy Options) Program.

Presently, we have anunnsustainable carbon-based economy with several severe limitations, including a limited supply of fossil fuels, high cost and carbon dioxide pollution. We wanted to create a practical and sustainable energy strategy for automobiles that could solve each of those limitations, eventually using renewable energy sources and in an environmentally conscious way. - Andrei Fedorov, associate professor in the Woodruff School of Mechanical Engineering at Georgia Tech and a lead researcher on the project.

Little research has been done to explore carbon capture from vehicles, but the Georgia Tech team outlines an economically feasible strategy for processing fossil or synthetic, carbon-containing liquid (bio)fuels that allows for the capture and recycling of carbon at the point of emission. In the long term, this strategy would enable the development of a sustainable transportation system with no carbon emission.

Georgia Tech’s near-future strategy involves capturing carbon emissions from conventional (fossil) liquid hydrocarbon-fueled vehicles with an onboard fuel processor designed to separate the hydrogen in the fuel from the carbon. Hydrogen is then used to power the vehicle, while the carbon is stored on board the vehicle in a liquid form until it is disposed at a refueling station. It is then transported to a centralized site to be sequestered in a permanent location currently under investigation by scientists, such as geological formations, under the oceans or in solid carbonate form.

Note that if biofuels are used in the system, a carbon-negative cycle emerges that actively removes CO2 from the atmosphere. The more one were to drive the car, the more one would be cleaning up the atmosphere and fighting climate change
