Turning car exhaust into diesel
This is fascinating:
The world's richest corporations and finest minds spend billions trying to solve the problem of carbon emissions, but three fishing buddies in North Wales believe they have cracked it.
They have developed a box which they say can be fixed underneath a car in place of the exhaust to trap the greenhouse gases blamed for global warming -- including carbon dioxide and nitrous oxide -- and emit mostly water vapor.
The captured gases can be processed to create a biofuel using genetically modified algae.
The article says the device can capture up to 95 percent of the carbon dioxide present in car exhaust; it's then fed to the algae, which is then harvested and turned into biodiesel. All the carbon dioxide emitted by cars in the UK could be captured and converted with this technology using only 1,000 acres of algae. The inventors also claim it could be scaled up to capture CO2 from industrial smokestacks.
