Labor Day will soon be upon us, and with it, the unofficial end of summer. Back to school time. Summer is the season for camping, getting out of the city and getting a little dirty in the woods. Some folks like to tent it. Some folks like a travel trailer, with their own bathroom (my wife included).
But one problem with campers is how much they weigh, the large vehicles needed to tow them and frequent trips to the gas station. Travel trailers are getting lighter and lighter, however, and easier and more affordable to pull. Take a look at the latest entry, from EverGreen (like the tree) in Middlebury, Indiana.

Editor’s Note: Carrotmob is a form of consumer activism that invites businesses to compete in order to win a mob of customers. But everyone wins, because the extra money the winner makes goes toward things like improving their energy efficiency. Usually the business who promises the largest percentage of revenue from the event wins, but this Carrotmob was done a little differently. Each contestant explained what they’d do if they won, and what they were currently doing around sustainability, and the general public voted, actually choosing the one who had already shown the greatest commitment to sustainability. Epicenter wanted to get some feedback from the public around what type of to-go containers to use.
What is the most sustainable type of take-out packaging?
Ah yes, the burning question that keeps many an environmentalist tossing and turning well into the night. On the one hand, PLA, aka “polylactic acid” comes from plants, not petroleum, so it must be good, right? But which plants does it come from? And what part of the plant? Is it waste being upcycled? Is it replacing food crops? It must be good, right, it’s not petroleum!?
Epicenter Café, being a very conscientious Carrotmob winner, wants to be sure they make the right choice. They also want your input, sage readers. So I present to you the options, because even the Green Café Network does not take an official stance on this ever-evolving topic. There is an increasing array of options for eco to-go containers.

The summer of 2009 has been cooler than usual in the Midwest, but Mother Nature can still pack a punch.
August has seen some 90-degree days in places like Michigan.
When it get this hot, some people like to stay inside in front of the air conditioner (based on recent Twitter and Facebook updates). But it doesn’t have to be this way.
The air conditioner, I mean.
A “whole house fan” that uses the attic for venting can keep your home cool with less electricity (and for less money) than modern-day air conditioning.

You know the drill. You flush the toilet, walk away, come back later and it’s still running.
You jiggle the handle. Hopefully that makes it stop. Maybe you take off the top of the tank and swear a little.
Or, you could install H2Orb, a toilet gadget from a California company that takes clean tech to a whole new level.

How do you make a better wind turbine? With lasers, of course.

Barnacles, algae and other marine biofilm can reduce a ship’s fuel efficiency by up to 40%, and the U.S. Navy is working on a way to keep its hulls clean without using expensive chemicals. Up to now, the Navy has been relying on biocides to keep the pesky hitchhikers at bay. On top of harming marine life, the chemical regime is not ideal for keeping high-performance warships operating at peak efficiency. The Navy estimates that it spends an extra one billion dollars yearly on chemical biocides and extra fuel, so in addition to pure environmental altruism there are significant tactical and bottom-line incentive to find a better way to prevent biofouling. In what can only be described as poetic justice, naval researchers are turning to the marine environment itself to find safe, effective solutions to the problem.

As it stands, most vehicles in the world right now run on one of two fuels: gasoline, or diesel. While they perform the same function, and on the outside the engines look the same, they work in very different ways. While diesels have made progress in becoming cleaner burning, gasoline cars still dominate America’s highways.
But what might happen if someone mixed these two fuels up in the same engine? According to a research group from the University of Wisconsin, Madison, the engine not only becomes more thermally efficient but cleaner burning, too.

You’re waiting at a red light, your engine idling lightly. You check the crosswalk signal: 20 seconds, you have some time. You turn your classical music up a notch to the perfect volume and you close your eyes, relaxing on your way home from work. But your moment of relaxation is interrupted by the thump thump of bass coming from the car next to you. You look over at the car, the tinted windows keep you from seeing the driver. [...]

A UK company has launched a new device that allows users to cut-off their water supply at the flick of a switch, drastically reducing wasteage and giving a significant boost to water conservation efforts.
Instead of scrabbling around looking for the stopcock, the new Surestop device allows users cut supply instantly, saving water loss, and consequent damage, whilst giving householders direct control over water consumption.
Now the company hopes to expand into areas crippled by drought, where water conservation is a pressing priority.
