It always irks me how those news of ground-breaking improvements in this and that actually never translate into improvements in greenhouse gases emissions or cleaner air (or do 10 years later in another form without my being aware of it maybe). There's already a few companies (one of them is Tesla Motors, an American company) working on cars that actually cut emissions dramatically and do in fact put a dent into the polluting, gas-guzzling model of the "modern" car paradigm.
