A better way to keep cool

[podcast]https://edwardwillett.com/wp-content/upLoads//2010/06/A-Better-Way-to-Keep-Cool.mp3[/podcast] We all have our preferred temperature. Me, I like it cool. My poor college roommate can attest to that, since I just about froze him out of our room, aided by the fact I was tall enough to easily reach the air conditioning controls and he wasn’t. But hey, that was in Arkansas, and …

Fuel from germs

[podcast]https://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 …

Liquid fuel from solar power

[podcast]https://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 …

Turning anything to oil

Imagine a process that can turn any kind of organic waste into high-grade oil. It sounds too good to be true. But that’s the promise of the thermal depolymerization process (TDP), outlined in the May issue of the respected popular science magazine Discover (from which most of the following information is drawn). Naturally occurring oil …

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 …

Chernobyl

This week, Ukrainian authorities restarted the last working reactor at the Chernobyl power plant, site of the world’s worst nuclear disaster 13 years ago. Officials say the reactor is completely safe and free of any potential Y2K bugs. Considering that everybody living in the northern hemisphere 13 years ago was the unwilling recipient of at …

Wind power

Even in the years when we don’t have much in the way of crops around these parts, we always have wind–which got me thinking, isn’t it a shame there’s no way to farm the wind? (It’s not a new notion; after all, even the Bible says, in Hosea 8:7, “They sow the wind and reap …

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

Our modern society is based on “fossil fuels,” which may sound to you like we’re burning dinosaur bones for heat. We aren’t, but we are burning the remains of plants and animals that lived millions of years ago, releasing the solar energy the plants captured through photosynthesis and the animals captured by eating the plants. …

Fusion

Nuclear fusion as an electrical power source is rather like some people’s plans for after they win the lottery. They’re sure it’s coming, and they’re sure it’s going to be great, but somehow it never seems to happen. Actually, that’s not a very fair comparison, because nuclear fusion really does seem to be on the …

Fission

We sometimes talk about living in the Nuclear Age, because it has only been in the last 50 years that we have managed to harness the power expressed by Einstein as E=mc2. But strictly speaking, uranium fission, which is what we think of when we think of nuclear power, isn’t new. About 1.78 billion years …
