With summer right around the corner, restless employees are eagerly scratching at the doors to get out of the office and slip into their fantasy vacations. One thing that we should all consider is the impact that our summer travel is going to have on the very places that we are dying to get out and enjoy.

Fortunately, some hotels and travel companies are getting the message and are making changes to help conserve and reduce impact. Several options exist to minimize your footprint on the road and in the skies this summer.

Homemade ethanol guru Floyd S. Butterfield and Silicon Valley entrepreneur and innovator Thomas J. Quinn want to see you making ethanol in your backyard. Their creation, called the E-Fuel 100 MicroFueler, is a stacked washer-dryer sized reactor that can convert sugar into ethanol for (they claim) $1.00 per gallon.

Before you get too excited, please note that the unit is probably too expensive for your next block party, unless you’ve got an extra $9,995 lying around somewhere. Fortunately, state and Federal tax credits can halve this, but that still keeps it out of the price range of the average American.

This 100% biodiesel-powered, 78 ft wave-piercing trimaran aims to set an around-the-world speed record while maintaining a net zero carbon footprint. The Earthrace left Sagunto, Spain, on April 27, and has already made excellent time across the Atlantic, landing in Panama just 8 days later.

Inspired by the desire to “connect with people about the need to get renewable fuels into our energy mix and to inspire them to do something,” the Earthrace has already generated a whirlwind of publicity. Much of this is due to the boat’s eco-technological appeal. It’s been described as “a rally car but for oceans”, with the ability to submerge up to 23 feet underwater while powering through the ocean. The “eco-” part doesn’t just include circling the globe on 100% biodiesel. Parts of the boat are made from a hemp-based composite, bedding foams are made from canola oil, and the operation’s total carbon footprint has been balanced by purchasing carbon credits.

Headlines from today’s White House press conference included a quote from President Bush encouraging Americans to eat local. It caught me a bit off guard.

Putting the comment back into context, however, there are a few problems with the logic of this suggestion, and not just that he, Bush, was the creator of the “eat local” concept.

The statement was made in response to a question on the relationship between ethanol and food price increases: (quote from press conference after the jump).

Two “Extinct” Species Discovered

First there was Swinshoe’s softshell turtle, and then the Javan Elephant. Is this more commonplace than we might believe?

Frankly, no. Despite the occasional hubbub over an animal science has lost track of– say, the Coelacanth– we’ve witnessed something extraordinary. Swinshoe’s turtle was previously believed to be extinct in the wild, with only three remaining in captivity, and therefore every one of these 300-pound turtles is a critical find.

It looks like Solazyme will be making algal biodiesel for the US military, after a test-drive demonstrated the fuel’s superior cold-weather properties when compared to commercially-available biodiesel.

Former Director of Central Intelligence and Under-Secretary of the Navy R. James Woolsey tested the fuel himself by driving to the Worldwide Energy Conference & Trade Show in an unmodified 2008 Ford F450 fueled by 100% algal biodiesel.

Editor’s note: The Santa Fe Women’s Group in Costa Rica is empowering themselves by making biogas from manure. Written by guest author Thomas Carmona.

As if cooking, cleaning, and child-rearing were not enough, the women of Santa Fe also lead a powerful organization, the Santa Fe Women’s Group, which fulfills many vital roles for the community. One of the group’s biggest projects has been producing biogas.

The Project

The Santa Fe Biogas project, in its initial stages, was simply a concern communicated in Women’s Group meetings: “How can we avoid buying expensive tanks of gas and inhaling smoke in the kitchen?”

Researchers at the University of Massachusetts-Amherst have made a potentially ground-breaking discovery in the production of biofuels from sustainable, non-food sources.

By heating cellulosic plant material to between 750 and 1,100 degrees Fahrenheit in the presence of a catalyst, then quickly cooling it, the team of graduate students led by associate professor George W. Huber was able to produce a mixture of hydrocarbons identical to gasoline in less than two minutes. The conversion is a relatively simple, one-step process that could create biogasoline for as little as $1 per gallon.

Researchers at Michigan State are trying to get corn-stover to digest itself after harvest. Doing so would mitigate the costly pretreatment steps needed for the production of cellulosic ethanol from the non-edible parts of the corn plant.

MSU’s scientists are adding genetic material to the corn’s genome, genes that would normally be responsible for the digestive enzymes produced by fungi and the microbes in cow rumens. The newly transgenic plants store these enzymes in vacuoles in the leaves and stalk in a way that doesn’t affect the plant while it’s alive.

Sustainable Industries article indicates that the air transportation industry is looking for ways to cut fuel costs by becoming more efficient and green.

While the first algae-to-biofuels facility went online today, scientists at Argonne National Labs are manipulating the photosynthetic super-organism for another use: creating hydrogen.

Algae grows prolifically in adverse conditions, and can store large amounts of oils or starches useful for making biodiesel or ethanol. But some strains also use an enzyme called hydrogenase to produce small amounts of hydrogen gas. Scientists think this is the organism’s way of getting rid of excess energy under high-light conditions.
