Wind turbines are cool. The might not be able to replace all the coal power plants in the world, but they're a great example of how old concepts and new technology can be put together like peanut butter and jelly to become a delicious source of power. They're also a great example of the sort of positive environmentalism that sees efficiency and economic growth as two sides of the same coin. I would go so far as to say that most of the various groups opposing wind farms around the country are really lame. But what if I wanted to join in on the blade-spinning fun, instead of just blathering on and on about it on the Internet? There's a cool-looking rooftop vertical-axis wind turbine (VAWT) from a company called Mag-Wind that looked really promising when I first saw it late last year. It's compact, doesn't require a tall mast, and it's designed specifically for roofs. Unfortunately, it might not be on the up-and-up. Paul Gipe at Wind-Works.org ran some numbers and he doesn't think the power output they are claiming is possible. There's also some talk of a fake Mag-Wind dealer (not actually authorized by the company) taking a whole bunch of people's money in North Dakota. More interesting discussion can be found at Treehugger. This is unfortunate because I had dreamed up a plan to put one of these guys on top of my roof any then buy a plug-in hybrid like the Chevy Volt. Charging a battery at night is already cheaper than buying gas according to Prius conversions. I'm just the kind of geek who goes out and spends money on sort of thing. Now it is possible that the calculations are off, because no one seems to have been able to make any independent measurements yet. Maybe the assumptions are wrong - for example, when they say 1100 kWh/month in a 13 mph average wind, maybe they are talking about the wind measured in a clear area away from buildings, like you see on the weather report. Because of the "roof effect" the wind actually hitting the turbine would be more than 13 mph. Also, this isn't a completely fictional company, their representatives and distributors have contacted bloggers and other writers here and there. So I guess I'll hold out a little hope and keep an eye out for something to materialize from these guys. In the mean time, anyone have a recommendation for a roof-mounted wind turbine that definitely exists? Maybe the WindCube (man that is cheesy-sounding bad name)? Oh, and here's some footage of various wind turbines in action in Taiwan. Not too exciting, but it shows that some people have working VAWTs up and running. [youtube]n0_lmtfwUYg[/youtube]

Earlier one of our writers stumbled on a report that claimed gas-guzzling Hummers were better for the environment than hybrids like the Toyota Prius. This is one of those great stories that everyone loves - where the conventional wisdom is wrong, and we can all have a good laugh knocking someone or something off it's high horse. This story has been passed furiously around the Internet for a week or so, by email and blog, featured on Digg and Slashdot. It's a good anecdote about unintended consequences and a little boost to Hummer owners who are sometimes criticized for their very conspicuous consumption. It's also pretty much a load of crap. But how can that be? The writer did a bunch of research, and came up with numbers and formulas. Lots of people saw it and voted with a thumbs-up in Reddit or StumbleUpon. Welcome, dear readers, to the world of white papers and press releases. Let's say you had a conclusion you wanted to support, or clients you wanted to flatter. You do a bunch of research, finding information that backs your conclusions. Now what to do with it? You can try presenting it at a conference or submitting it to an academic journal, but then you run a risk. The risk is that peer review will knock it down. The scientific method has a key difference from the method mentioned above - instead of creating a conclusion then finding evidence, you create a hypothesis, gather all the evidence, then form your conclusion. Take this pesky detail and add a dash of scrutiny by experts in the field and you have a pretty good recipe for coming up with useful theories and knowledge. The recipe just won't make the muffins come out exactly the way you want them every time. So what do you do with this research? Put it in a white paper and/or type up and good press release. The term "white paper" used to refer to government policy documents, but now it's often used to mean a report by a company or individual in an industry intended to inform and persuade customers and partners. There's absolutely nothing wrong with this, so long as everyone knows that the purpose of the document is often to persuade or sell something, not to impartially report on all the facts. IT workers have become very familiar with the uses of white papers since we are constantly bombarded with them. They are notoriously available to prove nearly any point you want to make. Is Oracle the fastest database system? You can probably find 20 white papers that say so authoritatively and conclusively. Is Oracle bloated and inefficient? Look, there's 20 papers that say so authoritatively and conclusively. They aren't all worthless, because each one might give you some good factual information. It's up to you to find and use what you need without drinking the Kool-Aide. The use of email by lots of people outside the IT realm and recently the hug number of non-IT bloggers has given press releases and white papers some new possibilities. They can be spread around the world in record time and quoted by a 1,000 blog posts as if they were primary sources. Notice that this report on the Prius and Hummer is 450+ pages. How many people, do you think, read all 450 pages? There are a number of problems with this report that make the conclusion that Hummers are green and Priuses are baby- seal-clubbing smog machines hard to swallow. For one thing, it assumes that a Prius will only last 109,000 miles, which is lower than some parts of the warranty in California and similar states, while extending the life of a Hummer H1 to 379,000 miles. Plenty of Priuses have already passed 200,000 miles, often working in taxi fleets. It also mentions the use of Nickel in the batteries and the damage Nickel mining did to Sudbury, Ontario. The batteries are warrantied to 100,000 miles Nickel is recyclable. Sudbury has done a great deal to mitigate past environmental damage and is no longer a wasteland. As the TrueDelta blog points out, the cost of ownership numbers are amazingly high for all the vehicles in the report. If Priuses cost this much to build and operate, we have to assume that Toyota is taking a huge loss on every one sold, and in fact the entire auto industry is grievously undercharging us. There are a number of other problems with the report, but others have already done a pretty good job outlining them. Probably the biggest problem is that the source data is not available for review, since it is considered valuable intellectual property by CNW research. So what's the answer to the question posed in the title? How can a Hummer be better for the environment than a Prius? By using whatever methodology you want, using whatever data you want, and closing your research up from peer review, that's how. And what's the lesson for today? It's certainly not "don't believe everything that you read," because that is glib and cynical without being precise enough to be useful. Here are some thoughts that might be a bit more practical:

• White papers and press releases are fine, but keep in mind they are often intended persuade you or sell you something.
• Starting with a conclusion makes research easier, but doesn't validate your conclusion.
• Digg, email forwards, and 1,000 blogs do not count as peer review.

I am sure that most people out there don't really care if their car puts out a lot of carbon dioxide or whatever other bad gasses and liquids that leak from their choice mode of transit. I am sure, though, that most people care if they are getting really good gas mileage. Or if they don't care about the mileage, yes I am talking to you Hummer and other SUV owners out there (and don't tell me it's for car pooling! I never seen more than two people in a SUV ever), they do care about saving money. Which buying gas less often can do for you. Recently I have seen what GM has been experimenting with in the saving the world with better designed cars venture. I know that it will not acutally become a real car but the concept is really interesting. It's refreshing to see that car companies still know how to be creative, and it touches my tree-hugging hippie heart that they still care about the environment. Or, at least they noticed the sales of hybrid cars and decided they needed something fresh and innovative. Let's think about what could be cooler than a hybrid car. Something eyecatching and easy to remember. Something special. Something kinda rediculous and not manly at all. So, what am I talking about, you wonder? None other than the Hummer O2. Pretty clever, eh? Here's a picture: This is a car that is run by algae. And other stuff like hydrogen fuel cells. But look at the aglae. All that aglae is going to turn your louting and polluting CO2 into O2, perfectly breathable by animals and stuff. Probably people, too. The whole car is supposed to act as a leaf, with the algae consuming the byproducts of the motor (the carbon dioxide) and turning it into oxygen, just like a leaf would do in nature. This car would be doing it all the time, even when the car was not running. GM is incoperating a lot of different little car tricks into this vehicle as well showing that they have studied the industry: the hybrid breaking mehcanism for reclaiming energy in the tires, hydrogen fuel cell for the power source, the ugliness of a Hummer, ect. So, it's ugly and probably not going to be voted 2008s cutest car. But, it's the idea that counts. I mean, it's smart to use a reuseable resourse for our fuel, right? Right. I know, I hear the outraged cries of all of the enslaved algae but I think there will be benefits for them as well. I just don't know what yet. I mean, they would be getting all of the sunlight any chlorophyll owning specimen could ever ask for. It's an all you can eat sunlight buffet. Of sun-shiny goodness. Unless you live in Ohio. Then it's a lot of cloudy days. So, live in Florida and this is the ugly little car for you. And I hope you like green because there aren't going to be a lot of customized colors on this one. Maybe blueish (blue green algae) or reddish brown (red tide or dinoflagellates) if they can figure it out. On the website there is also a pretty colored schematic of how exactly they think this car will work. The man driving the car is sitting directly inside the hydrogen fuel cell as far as I can tell. And it looks like he has a tree growing out of his head, possibly a result from sitting inside the hydrogen fuel cell. But look at all the sunlight. I told you it would be a buffet.

Ford is in trouble. Some new models are doing well, but all their gas guzzlers are in decline big time. So CEO Bill Ford has hired his own replacement - Alan Mulally, formerly of Boeing.

What can Mullaly do to turn the company around, and why was he chosen? Bruce Nussbaum at Business Week says that Ford needs innovation in their business model, to be more like Apple and Amazon. I think he's right, but I will let those with more knowledge talk about how to improve Ford's business model (if you have ideas, please comment below).

What I will talk about is product innovation. I think Ford Motor Company has picked exactly the right person to be CEO, and here's why: the Boeing 787 Dreamliner. The Dreamliner is not just a new jet. It makes extensive use of advance carbon-fiber composite materials to make it lighter, stronger, and more efficient.

Ford needs something really innovative, not just more cup holders or higher, skinner windows. They need to build a car using similar composite materials and blow past everyone in terms of safety and fuel efficiency.

Just taking a nice, stylish mid-size car like the Ford Fusion and replacing heavy metal parts with composites could cut weight drastically. Forget about hybrids—even though I think they're wicked cool—advanced materials are the ticket.

This is not a new idea – a few engineers are trying to do something similar with the Aptera at Accelerated Composites. Mulally has the expertise and the contacts to get the materials, get the designs together, and build up to production capacity. This could even be a boon to Ford's union workers. Even though large parts of the Dreamliner are built in Japan and Europe, a lot of the composite work is being done in the U.S., and there's a lot of work to be done on scaling production techniques before China can compete on labor costs alone.

It would be a huge, non-trivial problem, with a lot of pitfalls. I certainly don't know enough to even begin listing the challenges to such a plan. But it seems obvious to me why Ford would pick Mulally after looking at the Dreamliner. I just hope it's obvious to Ford as well.
