Apparently not content with just one giant ongoing infrastructure project, Australia has committed to fully outfitting three of its biggest cities for widespread electric car use. In hardware terms, that amounts to 200,000-250,000 charging stations each for Melbourne, Sydney and Brisbane, with an additional 150 battery swap stations scattered between them. The effort will cost $1bn in Australian Dingo Dollars, which is about $667m USD. If that's not ambitious enough for you, consider this: it should be online in three years.
