Audi Using Bacteria to Create Synthetic Petrol and Synthetic Diesel

The downside of the plants is that they require large amounts of space

is developing a way for waste CO2 to be used to create synthetic petrol and diesel by using cyanobacteria.

The process involves filling 100m long tubes with water in which the bacteria live. CO2 is pumped through the water. When exposed to sunlight and the CO2, the bacteria feed on them and excrete what Audi calls e-ethanol and e-diesel.

The bacteria do not need fresh, clean water to produce fuel. They can use waste water or even salt water. 

Audi could install these facilities at their factories to use waste CO2 to create fuel. 

Audi has one small-scale factory under construction now, and if things work out, it may have a full scale, commercially viable factory ready in 2014.
