Can cars run on CO2?

    As far as I know, it is rather unlikely. Carbon dioxide itself is the result of combining organic chemicals (such as fossil fuels or ethanol) with the oxygen in the air – in other words, burning. This process is exothermic, meaning it releases energy, which is the reason we’re able to use it to power things. The conversion of CO2 back to O2 and organic compounds is mostly done by photosynthetic plants, which use the energy of the sun for this through a long and complex series of chemical reactions. There might be some chemical reaction that uses up CO2 while producing heat, however, the end product might be no smaller problem than the CO2 itself.
