Wind Power, Part One

Wired Science posted Monday about a new Department of Energy report that suggests the US could get 20% of its on-grid electricity from wind power by 2030. The report suggest that as it stands now, wind power and solar thermal power* are the only zero-emission power sources ready to be scaled up in a major way.

Personally, I’m not convinced the current big-power-plant-supports-a-large-area model is worth switching to new energy sources. Demanding that any new technology be able to produce large amounts of power in one spot overshadows technologies that can provide just enough power on the spot. Wind power may be able to do both.

The problem with wind power, traditionally, has been that any turbine large enough to produce significant amounts of power was too heavy to turn at all unless the wind was very, very strong. Using lighter weigh materials for the blades has helped significantly, but I think these guys have the right idea. Basically, they’ve strung together dozens of small turbines in parallel. Each makes a small amount of power, which adds up to some pretty significant voltage. They claim that, in high wind, their rig can blow out a bank of car headlights like flashbulbs. They’ve patented their design, but the Make blog is calling for someone to come up with a homemade version, since the design is basically a bunch of model airplane propellers strung along a pole.

*as opposed to solar photovoltaic power, made with solar panels. I’ve got an upcoming post planned on those two.

I Want One of These So Badly

Apparently, this isn’t the first commercial attempt at making a wristwatch/cellphone combo, but it is the first I’ve seen. And I want it very, very badly. Dick Tracy watches don’t have quite the same ‘ok, we’re officially living in the future’ cache that flying cars would carry, but they come damn close. And at $300, it’s not even that expensive for a fancy cellphone. I hope other people buy them, so in a few more iterations, there’ll be a knockoff I can afford.

Global Warming Smackdown

Filed under: energy and climate change,funny,Uncategorized — Tags: — Ethan @ 8:58 pm

From the Wired Science blog, a group of climate scientists recently challenged their competition to a bet. On Realclimate.org, a group of 6 global warming believers offered 2500 Euros to the authors of a recent Nature paper if, by 2010, their global cooling hypothesis pans out. There was some serious smack talking in the offer:

That this cooling would just be a temporary blip and would change nothing about global warming goes without saying and has been amply discussed elsewhere (e.g. here). But another question has been rarely discussed: will this forecast turn out to be correct? We think not – and we are prepared to bet serious money on this. We have double-checked with the authors: they say they really mean this as a serious forecast, not just as a methodological experiment. If the authors of the paper really believe that their forecast has a greater than 50% chance of being correct, then they should accept our offer of a bet; it should be easy money for them. If they do not accept our bet, then we must question how much faith they really have in their own forecast.

I hope they take ‘em up on it. If the future of the Earth isn’t enough to keep your interest, maybe a large-sum professional wager can do it.

Cocktail Party Bibliography: The Homophobia Study

Filed under: feminism,funny,gender,Uncategorized — Tags: , — Ethan @ 7:53 pm

For years now,  the UGA homopobia study has been one of my favorite pieces of social science, but I’ve never bothered looking it up before. A friend of mine’s dad worked on it, so I first got the rundown from her. Now, I’d like to sum it up for you, and give y’all the citation for the original article in case you want to look it up. I think I’ll do this from time to time, post a review/summary of a study I love or hate.

Long story short, this study looked at homopohbia in men, and asked the question we’ve all been thinking: are homophobic guys secretly into men?

The short answer is yes.

The researchers took a number of men (all white; I assume they didn’t want to bother controlling for cultural differences) who described themselves as fully heterosexual in preference and experience. They had the subjects fill out a questionnaire which asked them how they’d feel if they found out various people around them were gay, if a guy were to hit on them, etc. Using the results of that questionnaire, they chose  2  study group:  35  men who  were  homophobic, and a control group of  29  who did not have negative  emotional responses to  homosexuality.

Then, the hooked their volunteers up to a plethysmograph (a loop that fits around the penis and measures changes in its circumfrence, as a proxy for sexual arousal) and showed them porn. Both groups had similar responses to straight porn and lesbian porn, but there was a distinct gap in the way they responded to gay male porn.

The non-homophobic men were pretty bereft of hard-ons, with 66% having ‘insignificant’ arousal. Out of the remaining third, 10% were moderately aroused, and 24% had definite boners.

The homophobic men were much more into it. A mere 20% of them had insignificant changes in their penis metrics, while 26% were moderately aroused and a whopping 54% were definitely turned on. That’s some serious statistical significance.

What’s better, when the participants were asked later which videos had aroused them, all participants gave answers that matched the peter-meter measurements, with one major exception: the homophobic men consistently underestimated their response to the gay porn. Either they were lying, or they were in enough denial to not notice they  were turned on despite having their pants around their ankles and a bonerometer on their dicks. You be the judge.

Now, before the gloating goes too far, there’s a couple of points I want to cover. It’s possible, though less likely, that the homophobic guys got hard-ons because the gay porn made them nervous, or because a bunch of them were exhibitionists. Also, the study tells us noting about homophobic women. And lastly, I’d be interested in seeing a breakdown by religion–I want to know if people who are told by their clergy that gay folks are going to hell really internalize that message all the way to their crotches.

Anyway, I couldn’t find the article anywhere on the open web, so I’ll just give you the citation:

Henry Adams, Lester Wright Jr. & Bethany Lohr. “Is homophobia associated with homosexual arousal?”, Journal of Abnormal Psychology, 105 (1996), P. 440-445

Next time you find yourself arguing with a homophobe, you’ll have a handy trump card.
You can thanks me later.

Let’s Kick Things Off

Filed under: feminism,gender,media and pop culture,Uncategorized — Tags: , , — Ethan @ 7:54 pm

The current issue of Bitch magazine has an article entitled Mad Science: Deconstructing Bunk Reporting in 5 Easy Steps that I just love. the author, Beth Skwarecki, lays out a great framework for spotting dubious science reporting in mainstream media. To pile on the awesome, she colors the whole deal with studies about gender, from whether male monkeys prefer trucks over dolls to the ‘housework prevents breast cancer’ debacle. It’s not the most fun part of the article, but this part pretty much sums up her thesis:

Ben Goldacre, who writes the “Bad Science” column for the UK’s Guardian, speculates that science stories come in three varieties: the wacky story, the breakthrough story, and the scare story. Most widely reported studies on gender seem to fall into the wacky category—the supposed innate preference for pink is one of them—and their media strength is that they tend to support existing stereotypes of women, reassuring readers that social stereotypes do, in fact, reflect reality.

We can’t put all the blame on mainstream media, of course. Scientists are part of the same culture as the rest of us, and they too have biases that shape their hypotheses and interpretations. The scientific community can also be as fad-driven as popular culture, creating a climate in which many researchers simultaneously geek out over one specific theory while competing ideas get lost or abandoned. So let’s learn how to read between the lines of these dubious articles. Next time you see an article reporting that women are happiest when they’re picking up their man’s dirty socks, try asking these questions:

1 Do the Conclusions Fit a Little Too Well With Cultural Stereotypes?
2 Does the Study Agree With the Headline?
3 Can You Spot the Double Standard?
4 Is There Another Conclusion That Would be Just as Valid?
5 Is the Study Even Science?

Each point gets  a little mini-essay of it’s own. Really, though, you should just go read the whole thing.I’ll be testing you on it later.
