Fuel from germs
[podcast]http://edwardwillett.com/wp-content/upLoads//2010/01/Fuel-from-Germs.mp3[/podcast] For years, we’ve been turning crops such as corn, wheat and sugar beets into fuel, using yeast to convert sugar into alcohol. But there’s an obvious problem with this. That stuff we’re turning into fuel is also food for humans and feed for animals. (And as an aside, how come we always call it “animal feed” as opposed to “animal food”? And why don’t we ever refer to “human feed”? Hmm?) A lot of the plant is wasted when you grow crops for fuel or food. The leaves and stems, with their tough cell walls made of cellulose, hemicellulose and lignin, are more of a nuisance than anything else. Wouldn’t it be great if there were a use for what is now plowed ...Honeybees in decline
Honeybees, particularly in the United States, are in decline. In 2007-2008, 36 percent of apiaries surveyed by the Apiary Inspectors of America and the U.S. Department of Agriculture reported that some of their colonies had simply...disappeared, a phenomenon known as Colony Collapse Disorder, or CCD. In the most recent survey, covering September 2008 to April 2009, 26 percent of the apiaries reported that some of their colonies were lost to CCD, a lower number but still alarming: not just to beekeepers, for whom these kinds of losses are economically unsustainable, but for those of us who like to eat, because bees pollinate 80 percent of fruits and vegetables, and a much as a third of the food we consume relies on ...Liquid fuel from solar power
[podcast]http://edwardwillett.com/wp-content/upLoads//2009/07/Liquid-Fuels-from-Solar-Power.mp3[/podcast] In recent years, scientists and engineers have turned to biofuels—fuels generated from living things, and hence renewable—as a means of weaning us off of fossil fuels in favor of something cleaner, less likely to run out, and less wrapped up in international geopolitics. Fermenting the sugars found in corn or other grains into ethanol has been around for a long time, of course, and it’s pretty much a proven technology. On the other hand, do we really want to be turning food into fuel? More promising have been recent advances in turning lignocellulose, the stuff that makes up the cell walls in plants, into ethanol and other fuels: that would allow us to use grasses, wood chips, straw and other non-food as ...Future energy sources
A lot of attention in Canada has been focused recently on the Kyoto Agreement to limit the emission of greenhouse gases. But scientifically, the goal for preventing possibly catastrophic global warming has been set far higher than Kyoto's modest reductions. An article in the November 1 issue of Science sets out the challenges. Entitled "Advanced Technology Paths to Global Climate Stability: Energy for a Greenhouse Planet," it was written by a team of 18 scientists and engineers from major universities (including McGill), U.S. government laboratories and agencies, and even Exxon Mobil. The U.S. Department of Energy funded the project. The level of carbon dioxide in the atmosphere has increased from 275 to 370 parts per million ...Challenge Bibendum
Will we be driving gasoline-powered cars 10 or 20 years from now? Judging by the 2001 Michelin Challenge Bibendum, some of us will, but many won't. The Challenge Bibendum (Bibendum is the real name of the made-of-tires Michelin Man) offers manufacturers an opportunity to demonstrate alternative-fuel vehicles in real-world conditions. This year's challenge drew 27 production cars and 18 prototype cars. It included a critique of the vehicles' design at the Automobile Club of Southern California, a performance test at the California Speedway in Fortuna, and a 430-kilometre drive to Las Vegas. Several different power sources were used. Six cars in the competition didn't use an alternative fuel at all--they used gasoline. Technological improvements ...Global warming update
What with all the talk about the greenhouse effect recently, I decided it's time for a quick review... The term "greenhouse effect" is usually used today in reference to a predicted gradual warming of the Earth caused by an increase in various gases in the atmosphere, primarily due to human activity. Really, however, the greenhouse effect has been at work for eons, which is a good thing, because it's what keeps Earth's mean surface temperature high enough (17 degrees Celsius) for life to thrive. About 40 percent of the energy we receive from the sun arrives at such short wavelengths that it zips through the atmosphere unimpeded. ...Landfills
ou know, I produce a lot of garbage (and no, I'm not talking about this column). I'm not alone, either: Canadians produce more garbage per capita than any other nation in the world. Regina alone produces, on average, 600 tons of residential waste a day. That garbage has to go somewhere, and in most communities, that "somewhere" is a landfill. In the most common kind of landfill, trash is dumped in a hole in the ground, spread out in layers, compacted as tightly as possible, and then covered with soil. Each completely covered, compacted unit of waste is called a cell; in Regina's landfill, by way of example, each cell consist of three ...Alternative fuels
Having written about fossil fuels, it behooves me to also write about alternatives, lest I neglect my environmental duty. Besides, I have all these left-over notes ... We use fossil fuels primarily for power generation and transportation. Huge strides have been made in reducing emissions, but scrubbers and catalytic converters don't change the fact that fossil fuels are non-renewable, or get rid of carbon dioxide, the main culprit in the projected global warming. This has spurred the search for alternatives. Fast-flowing rivers can be harnessed to spin turbines and generate electricity. Hydroelectricity doesn't pollute, but its dams and river diversions can flood habitats. Nuclear fission splits the ...Green technology
There is a tendency for people to see "technology" and "environment" as mutually exclusive terms. Technology is sometimes portrayed as the cause of the world's environmental problems, and the abandonment of technology as the cure. Well, it might be true that the world's overall environment would be in better shape if we'd all stuck to living on nuts and berries in unheated caves--and maybe we would have if not for this darn thing called intelligence. First it was the spear, and then there was fire, and then some fool invented the wheel and the next thing you know, here we are in the age of computers, telephones, airplanes, satellites, CAT scans, smallpox vaccinations, ...The greenhouse effect
Presumably, by now, you've heard of something called the "greenhouse effect." (If you haven't, we'll pause briefly while your next-of-kin checks to see if you're still breathing.) The term "greenhouse effect," as usually used today, refers to the predicted gradual warming of the Earth due to an increase in various gases in the atmosphere, primarily due to man's activities. There is considerable debate as to just how serious this warming is going to be--and whether it has begun yet. (Despite the warmth of the '80s in our part of the world, the most recent and most accurate study of the Earth's temperature, carried out by satellites over the last decade, shows no evidence ...

Lost in Translation
Kathryn was a human empath whose world and life had been destroyed when the alien S’sinn slaughtered her parents before her very eyes. Jarrikk was a young S’sinn, an unproven warrior who’d seen his flight mates slaughtered by the humans who’d sought to colonize his world.
As humans and S’sinn found themselves on the brink of war, these two Translators had to work together to find a common ground and avert catastrophe. But whether their Translators’ oath and training could overcome the enemies leagued against them was very much in doubt…

The Bounty Mutiny
The Bounty was a British ship visiting Tahiti in 1789 when some of the crew overthrew the captain, William Bligh, and set him adrift in a tiny boat with sailors loyal to him. The mutiny resulted in a number of trials–both of the men who mutinied and of Bligh for losing command of his ship. These fascinating events have been the source for numerous Hollywood movies, most recently The Bounty. The Bounty Mutiny: From the Court Case to the Movie explores the famous case and the movies it inspired.
