Philosophia Naturalis — a slight delay

For those waiting for the next installment of the Philosophia Naturalis blog carnival, I’ve got to announce a slight delay — rather than today, I’ll be posting it tomorrow. Due to some work commitments pouring over into my home time, I haven’t quite had the free time I’ve needed to do the job well.

I’d rather be a bit late than produce a shoddy product; thanks for your patience… Continue reading

Googlediving, hybrid vehicles, and energy consumption

A recent thread of discussion (namely, some comments on the hybrid cars podcast episode) brings me to remind you of the wisdom of cross-checking ostensibly “scientific” things you hear in conversation, or see mentioned in print or online somewhere. Fortunately, it’s pretty easy these days to check things using the internet. When I run across something that seems to be questionable, I’ve gotten into the habit of doing a quick bit of checking things out with Google. I call this “googlediving” — it’s essentially the information equivalent of dumpster diving but doesn’t leave you all smelly when you’re done. Best of all, it usually takes just a few minutes to run a quick check.

Let’s look at the recent discussion as a good example….

Episode 14 — Hybrid Cars

If you’re like many people, you’d like to help do something about climate change through the choices you make and the way you live. Celebrities and the mass media (among others) are presenting hybrid vehicles as a big step forward in this regard.

But left out of this rush to technology is any discussion of the fact that not all hybrids are equal. Some are little different from conventional cars, and consume fuel with equal gusto. Others offer dramatic improvements in fuel economy, but may not appear at your local automotive dealer’s showroom floor for years.

What’s a well-intentioned, but budget-minded potential car buyer to do?

Listen in to this episode, and I’ll give you a quick education in hybrid vehicle technologies. You’ll be able to tell series from parallel, and electric from hydraulic with aplomb — and more importantly, understand some of the challenges that lie ahead for this technology, and how to tell when a hybrid vehicle’s price premium makes it a worthwhile investment.

This episode is the first in a series on ways you and I can help fight climate change.
