Free Radicals is DT228 student Mark Dunne‘s prize winning final year project based around the chemistry of the Ozone layer. The player controls a nanobot called “Dobson 1.0″ who’s sole purpose it to reduce the effects of ozone depletion, this is achieved by converting greenhouse gas molecules (CO2, H2O, N2O, CH4) into O3(Ozone), in doing so repairing the hole in the ozone layer. Weapons and a power source will be absorb through the breakdown of the greenhouse gases. It will be a race against time, with the “Dobson 1.0″ having to produce enough O3 to stabilise the ozone layer. Free Radicals molecules(CFCs, NO, OH) will be constantly breaking down the Ozone molecules at a faster rate than the UV light they absorb so the Dobson 1.0 will need to destroy these before producing new ozone molecules.
