Volvo Testing Automobile Train Concept - SARTRE Project

Volvo and a handful of other companies are testing a system known as SARTRE (Safe Road Trains For The Environment) which would allow commuters to line up behind a lead vehicle and create an autonomous train, well autonomous for everyone but the lead vehicle. The benefits are said to be environmental, in safety, and in productivity / time savings as the riders in the trailing cars can leave the driving in the hands of the lead vehicle's operator and focus on other tasks.

I'm in awe of the technological achievements displayed in the following video, and at the same time have a bunch of questions and concerns, many of which the researchers are already considering as demonstrated.

Viewing The Worlds Glaciers - From Space

The good folks at Wired's Wired Science blog have compiled a collection of images, captured from space by astronauts and satellites, of some of the worlds most impressive glaciers. "To a geologist, glaciers are among the most exciting features on Earth. Though they seem to creep along at impossibly slow speeds, in geologic time glaciers are relatively fast, powerful landscape artists that can carve out valleys and fjords in just a few thousand years."

Here is one from the collection. "Covering nearly 1,400 square miles, the vast Heiltskuk Ice Field lies in the southern Coast Mountains of British Columbia. Taken by an astronaut on the International Space Station, this photo captures the snow-covered mountain slopes as well as several of the ice field’s valley glaciers, which are wide swaths of slowly flowing ice and debris."

How Much Greener Are Rechargeable Batteries?

I just read a short article in Wired - 16.11 which asks "Am I doing terribly wrong by the planet if I use alkaline batteries instead of rechargeables? I mean recharging requires power, right?"

I've always just taken it for granted that rechargeables would be more environmentally friendly and never really put a great deal of thought into how much more green they may or may not be. According to this article, a 2007 study by Bio Intelligence Service (sponsored by a French rechargeable battery maker) claimed that wearing out a single rechargeable battery impacts the environment less by a factor of 28 times. Makes me appreciate them all that much more!

The Greenest Town In America

Greensburg Kansas, was devastated by a tornado on May 4th, 2007 with nearly 90% of the city destroyed. When the residents decided to rebuild their community, they made a conscious effort to make it the greenest in the country. "The timing of all this is, in some ways, almost spooky," Daniel Wallach, a nonprofit specialist helping Greensburg rebuild said. "It's like the world was ready for this to happen, for a town to be completely re-imagined. The tragedy was terrible. But the folks here know that it also provided an incredible opportunity."

Mileage hackers going that extra mile

With the push towards being more eco-friendly and the increasing popularity of hybrid vehicles comes a new breed of drivers who are intent upon squeezing every last drop out of their gas tanks. The so called mileage hackers are resorting to all sorts of measure to take green to the extreme. The Globe and Mail has an interesting story about modifying hybrids such as the Toyota Prius and altering drivers mindsets, all measures that contribute to achieving amazing gas mileages of 70 to in excess of 700 miles per gallon. While I applaud the effort of these environmentally friendly evangelist, many of the measures are unrealistic for most of us. I personally considered the Prius in 2005 when I made my most recent new car decision but opted for the slightly less efficient Corolla, however I believe today's models are further apart in their fuel ratings. At the time I could not justify the cost of the vehicle vs. the gasoline savings over the life of the car. Yes, it would have been a small win for the planet but at least I didn't go for the Hummer. It is probably more realistic to think that we can all do the small things like checking tire pressure regularly and adjusting our speeds rather than paying $50,000 for a tricked out hybrid with solar panels. Unless there are a few sponsors out there willing to cough up some cash in return for splashing their logo on a pimped out green machine, I'll be working on easing the foot of the peddle in order to do my part. Kudos though to those who can afford to push their rides to the limit, perhaps some of these hacks will make it into future assembly line models.
