  • ...Tregoning and Washington Post reporter Jonathan O'Connell were speaking to the group about development and the zoning update. Many members of the audience were incredulous that any appreciable percentage of residents would choose to live without cars, even when O'Connell described many of his Petworth neighbors who do just that, or when Tregoning cited statistics from the Census.

    At the end of next year, Qatar Airways is scheduled to open a new airport that will include a 25-meter swimming pool and squash courts, among other amenities. But it will also be extraordinary from an energy standpoint because it will pump airline fuel made from natural gas.

    ...It’s a brave new autonomous world, with Google having logged over 300,000 miles in its fleet of autonomous hybrids, and AudiBMW and General Motors all racing to bringing the technology to market. But with great changes comes greater regulation, and after recent legislation making autonomous cars legal in California, Nevada and Florida, federal regulators are attempting to stay ahead of the rapid rise of the robo-car.

  • The Audi R8 e-tron won’t be coming to a dealer near you. A source at Audi confirms to Wired that the automaker has canceled plans to produce its all-electric supercar for mass consumption, citing the disadvantages of existing battery technology and the changing priorities of Audi’s new head of R&D....Conversely, Mercedes-Benz has reaffirmed its commitment to pursuing electric vehicle performance, showing off a new version of its SLS AMG Coupe Electric Drive at last month’s Paris Motor Show. That model – due to arrive in 2013 with a price tag of over $500,000 – manages a claimed 155-mile range with a 60 kWh battery pack, despite outputting an insane 740 horsepower and 737 pound-feet of torque.

  • Algae-based biofuel has long been one of the dark horses in the race for sustainable transportation fuels, and the US National Research Council suggests that it may remain in the shadows for a time....Even more troubling, however, are the fertilizer requirements. The amount of nitrogen necessary to keep algae happy and produce 39 billion litres of fuel, which is 5 percent of the US market, ranges from 44 to 107 percent of the country’s total nitrogen use today.

  • From bridges to broadband, America's infrastructure is supposed to be speeding along commerce, delivering us to work and piping energy and water into our homes and businesses. But just repairing all the breakdowns and potholes would cost tens of billions more than we're currently spending each year....The World Economic Forum put the U.S. 24th last year in the quality of its infrastructure, down from fifth in 2002. The rest of the developed world sets aside on average about 53 percent more of its gross domestic product on transportation infrastructure than the U.S. does, according to the Council on Foreign Relations.
