MyLongNickName writes: According to Reuters, cares could be fitted with a device to substantially reduce their emissions. A box can be inserted into the existing exhaust of virtually any car, trapping and storing the greenhouse gases in a stable form. These gases could then be reprocessed, using genetically modified algae, to create biofuel. The team of developers has worked on this for a couple years and has performed 130 tests, demonstrating an 85-95% capture rate. While I am somewhat skeptical, they are not making outlandish claims. If true, and it has no negative impact on gas mileage, this would be an incredible breakthough. Reduced emissions without requiring everyone to buy specially engineered cars.
