A new breakthrough in emissions reduction has been hailed as the greatest since the development of the catalytic converter. The 'microwave emissions converter' has already attracted worldwide media coverage not only for its ability to cut exhaust emissions by up to 90%, but also its 'waste' product, a film of industrial-grade diamonds, suitable for use in lenses and CD players, amongst others.Industrial researchers at the Swinburne University of Technology in Melbourne, Australia, announced the new microwave device for both petrol and diesel internal combustion engines on 28 September, allowing reductions up to 90% for carbon dioxide, carbon monoxide and hydrocarbon emissions.
