Maldives Go Green

The BBC says 2020 is when the country will eliminate their carbon footprint.

There is a growing consensus that, unless the world takes drastic action to slash carbon pollution, warming will tip beyond man’s control, unleashing unprecedented global catastrophe.

This is why, on 15 March this year, the Maldives announced its plans to become the world’s first carbon-neutral country in ten years. Our oil-fired power stations will be replaced with solar, wind and biomass plants; our waste will be turned into clean electricity through pyrolysis technology; and a new generation of boats will slash marine transport pollution. By 2020, the use of fossil fuels will be virtually eliminated in the Maldivian archipelago.

San Fran Power Outage After Explosion

An explosion and fire in San Francisco has led authorities to advise residents to stay indoors

An underground explosion in San Francisco’s Tenderloin neighborhood has prompted fire officials to issue a shelter-in-place warning this afternoon because of toxic smoke caused by an underground explosion and fire.

About 4,500 Pacific Gas and Electric customers lost power shortly after 11:30 a.m., when an underground explosion occurred in the area of Polk and O’Farrell streets.

Firefighters used CO2 to suppress the flames, but PG&E requested they stop using it in order to allow the equipment to fail completely, fire Lt. Mindy Talmadge said.

But when firefighters stopped using the CO2, a black cloud of smoke seven stories high rose from the manhole. At one point around 1:15 p.m., flames 10 feet high shot from the manhole.

The downtown area has been seriously impacted as buildings with smoke detectors automatically have shutdown systems including elevators.

Hot-Rod Diesel from GM

I certainly hope that the restructuring of GM will bring forward engine technology such as this awesome diesel V8:

These features give the new engine an unusually small, light, and narrow form factor for a diesel, with the ability to fit anywhere the current LS-series gasoline V-8 will go, according to GM sources. Potential applications mentioned so far include pickup trucks under 8,600 pounds GVW and the Hummer H2. While no passenger-car plans have been revealed so far, the new engine’s small footprint allows GM “the flexibility to introduce this engine in a wide variety of vehicle applications should there be future market demand,” according to GM statements. [And what a potential hot rod engine swap candidate! -Ed.

Nevermind the stupid Hummer box, which are being sold to the Sichuan Tengzhong Heavy Industrial Machinery Company anyway, this is the sort of thing that should be dropped into aerodynamic new designs.

Plastiki: Waste as a Resource

This could be a follow-up to my post about waste surveillance. Is the future really behind us? Bad joke, sorry. Seriously, though, the Plastiki project is an attempt to use some VERY low-tech recycling to make a boat:

David de Rothschild’s plan to sail across the Pacific Ocean, from San Francisco to Sydney in a 60-foot catamaran made of used two-liter plastic bottles, isn’t just an adventure. It’s a crusade. “Our philosophy of throwing everything away has to change,” says de Rothschild. “I want to use the Plastiki as a platform to help people think of waste as a resource.”

Rather than develop or innovate new ways of converting waste, however, the Plastiki seems like mostly an aesthetic and marketing-oriented project. It’s reality show drama more than real discovery or a leap in science and engineering, but nonetheless it carries a good message.
