Fuel from Trash Will Power California Garbage Trucks


300 garbage collection trucks in California will soon be fueled by the same trash that they haul. Landfill gas will be purified and liquefied, producing up to 13,000 gallons of liquefied natural gas (LNG) daily.

This facility at Waste Management’s Altamont Landfill in Livermore, California will begin operation in 2009. It comes with a price tag of $15.5 million, with grants providing $1.4 million.

Cleaner Fuel

Waste Management is the largest waste management company in North America and operates the largest US fleet of heavy-duty collection trucks. The company has a goal to reduce fleet emissions by 15% by 2020.

The new facility will reduce greenhouse gas emissions by more than 30,000 tons per year, according to Linde North America. LNG is a cleaner burning transportation fuel that emits less nitrogen oxide, carbon dioxide and particulates than diesel-fueled vehicles.

Duane Woods, senior vice president, Western group of Waste Management, said, “This will be the largest plant of its kind and we hope to break new ground by producing commercial quantities. Natural gas is already the cleanest burning fuel available for our collection trucks, and the opportunity to use recovered landfill gas offers enormous environmental benefits to the communities we serve.”

Demand for Low-carbon Fuels

California passed a law to reduce greenhouse gas emissions by 25% by 2020 and other states may follow. Demand for low-carbon fuels is expected to increase significantly in California as the state starts requiring a decrease in carbon emissions. Waste Management will be ahead of the curve by having plants like this in operation, creating lucrative business opportunities.

First Time In World History, Killer Whales Filmed Hunting Dolphins

Image from The Herald. Let’s see how long until we get a cease-and-desist.

A tour operator in Port Elizabeth, South Africa, unwittingly stumbled into the history books this weekend when he, his boat captain, and four tourists were in the right place at the right time to make the first recording ever of Orca whales hunting dolphins.

Ranier Schimpf was leading a group of divers when they noticed that one dolphin had been separated from a pod by five of the killer whales then repeatedly rammed. The dolphin was sent flying through the air by the force of impact from whales that were several times its size. With the smaller creature finally left laying unconscious on the surface, the whales pulled it below.

The two 7m male, two 5m female, and a 3m calf whales were clearly working as a team against the dolphin, and it appeared it was also a hunting lesson for the calf. More than that, they exhibited very protective behavior after the hunt. Becoming aware of the boat, they slowed, and began to circle the craft, investigating it. At that point the divers, making a decision I’ll only characterize as daring here, got into the water with the whales and kept filming them. This paid off, however. The whales, recognizing the humans as non-threatening, began to interact in a friendly way. The mother even presented the calf to one of the tourists, shielding it carefully, but allowing it to take a look at the strange visitors.

Capturing the hunting process of orcas, and their behavior immediately after, gives man access to a previously un-captured behavior that’s key to understanding the group dynamics within the pod. Conservation efforts are traditionally most successful when animals are the most thoroughly understood, and we are now, thanks to a group of tourists that were in the right place at the right time, a great leap closer to understanding both the hunting and social behaviors of killer whales.

VW Confirms 1L Concept Will Become Reality in 2010

mage source: Wikipedia

There’s been talk about the VW 1L concept for years. Since VW built the original, fuel economy, safety, price, and release date has been speculated upon and argued about, and I’d finally stopped thinking it was ever going to happen. However, according to VW’s CEO, it should hit the market in 2010.

The VW 1L is so named because, in theory, it only consumes one liter of fuel per 100 kilometers traveled. For those of us in the US, this translates into about 235 MPG. Definitely far and above anything on the market currently. The concept, developed in 2002, actually got better fuel economy, scoring a sweet .89L/100km in VW testing. It’s likely to use more fuel in real world use, but with that kind of mileage in testing it’s unlikely that anyone would complain about an “unsatisfactory 200 MPG.”

The thing is, that kinda of fuel economy comes at the price of riding in an extremely small two seater, with the two seats being one in front of the other, a la jet plane, rather than a standard side by side. The 1L also looks frighteningly close to the ground, which is part of how it pulls off a drag coefficient of .159, much better than any current production vehicle. While the final design isn’t done, VW will probably power the car with a 1 cyclinder diesel engine of displacement lower the .5 L, meaning the car’s speed will top out at 120 km/h.

The other obvious issue is the one I’m sure you’re all wondering about too. How safe is this thing? While I’m not usually one to complain about small cars, the 1L is extremely light and low to the ground. If it were released in the US I could easily see it being run over by any old F150 or Hummer. Nothing is out right now about safety, but as the production date nears, I’m sure VW will be doing lots of testing to reassure the public.

2010 isn’t that far off, in fact, it’s about the same time the Volt is supposed to be hitting the streets, so you’ll likely hear a lot more good and bad about this car in the coming months.
