After decades of frustration and failure, mankind’s dream of weaving a blanket entirely from the stuff of nightmares has become a reality.

For centuries, the very possibility of creating fabric from nightmares was considered little more than a fever dream, and the criminally insane resigned themselves to nightmare cloth substitutes, like hammered-flat baby rabbits, and prison toilet paper. Inventive though these are, like soymilk, they fooled no one.

Then, at the end of the 19th century, reports began to filter from Africa that a French missionary in Madagascar, exploring the dark peaks of his own madness, was creating fabrics of almost pure nightmare.

The missionary had supposedly created a spider-milking machine, into which he was placing massive Golden orb-weaver spiders, collected in their hundreds by local young girls. (Having little girls collect the spiders made the nightmare purer, but was not strictly necessary. Leave it to a missionary for such meticulous detail.)

The spiders were restrained in “a sort of stocks,” and then the beginnings of a strand of silk was coaxed from their abdomens and attached to a hand cranked wheel, at which point several hundred yards of the orb-weavers’ characteristically golden silk could be withdrawn from each spider. When the creatures could yield no more silk, they were released, apparently unharmed, back into the wild, where they would regenerate their webbing material after several days. The spooled spider silk could then be woven like any other material… but scarier.

Seemingly too “good” to be true, the missionary’s experiments were never replicated, and generations of madmen made do with sheets of dried bat saliva and mortuary blankets. Until now.

A “textile expert” and a visionary in what liberal arts colleges refer to as “insane studies,” Simon Peers and Nicholas Godley, recreated the missionary’s spider-milking machine, and after four years and one million spiders they have created an indestructible golden blanket, woven of pure nightmares.

The madmen discovered that while a single spider might produce a strand of silk up to 400 meters long, the material is, of course, exceptionally light. It took approximately 14,000 spiders to produce a single once of silk. The final 11 foot by 4 foot piece of fabric weighed about 2.4 pounds (~38 oz). So many, many spiders were involved, and lots of time. To help pass the long months of spider-milking, the artists whispered their secrets into mouse holes, and built razor blade houses.

The final intricately patterned textile has a rich, naturally golden color—the golden orb-weaver is named for the color of its silk, which attracts pollen-seeking insects in sunlight, and blends with background foliage in shadow. The spiders can adjust the exact tone of their webbing based on ambient light levels and color, so this textile has a unique shade based on how a million spiders perceived the room containing the tiny spider stocks.

The fabric is also exceptionally strong. Spider silk can stretch to 140% without breaking, and has tensile strength comparable to or exceeding that of modern fabrics like Kevlar, used for bullet-proof body armor. The complex protein structure that gives spider silk its strength has also makes it very difficult to reproduce artificially (that is, it hasn’t been done). Attempts have been made to insert the gene for spider silk protein production into goats, which then produce the protein in their milk, if not actual fibers. Unlike silk moths, spiders aren’t suited for mass production of silk, as they tend to kill and eat each other. And so it takes a madman, obsessed with drawing the secreted material for trapping prey from a hand-sized, venomous arachnid predator, to obtain enough spider silk to actually make something form it.

Despite civilization’s unwritten, yet long-standing rules against allowing madmen to have golden bulletproof cloaks, there is little to be done in this situation, seeing as how they made it themselves. Out of nightmares.

The textile is now on display at the American Museum of Natural History. (And, again, a photo of it can be seen here.

Good news out of Wyoming. A former University of Wyoming geology professor and his wife have contributed more than half a million dollars to an endowment created to upgrade and maintain the S. H. Knight Geological Museum on the campus of the University of Wyoming in Laramie. Matching funds from the state will double the amount. As you may recall the museum closed last July when its $80,000 budget was eliminated as part of a $18 million dollar cost-cutting effort by the university's Board of Trustees. The university reversed it decision after much public outcry, and the museum reopened seven weeks later, but with reduced hours and only a graduate assistant replacing its former staff (long-time curator and paleontologist Brent Breithaupt, and a part-time assistant). Whether there are plans to rehire Breithaupt is not known at this time, but at least it looks like the museum isn't in danger of extinction anymore.

Oh, you thought I forgot about the Geoengineering Extravaganza I promised, after just one entry? Did JGordon forget? Or is he just demonstrating a tremendous lack of respect for the Science Buzz audience?

Neither, respected friends, neither. First of all, I’ve never forgotten anything in my life. (This is in case anything I do eventually relates to someone else owing me money.) And I think I’ve demonstrated my respect for y’all over the years.

No, what happened was this: on Tuesday evening, my sock caught on a nail sticking out of my kitchen floor, and I went down like a redwood. Dried or decomposing pieces of food cushioned the fall for most of my body, but I’m afraid my face landed squarely in the mousetrap, which I had just baited with fresh poison. Luckily the trap pinned my lips shut before I ate too much of the poison, but I mix some potent poisons, and it only took a little to put me out.

My poisons are designed to remove a mouse from consciousness for anywhere from a week to several months, long enough for me to shave them, and ensure that they wake up somewhere frighteningly unfamiliar, like Thailand, or inside of someone recovering from major surgery.

At any rate, I was out for almost all of yesterday. It’s good that I woke up when I did, because I was covered with mice, but I’m afraid I just never found the opportunity to do another geoengineering post.

Until now.

So, let us continue with the “forget about the greenhouse gases, and just cool this place off, now!” theories. That is, those theories that could reduce the amount of absorbed heat (from the sun) rather than reduce what’s storing the heat (greenhouse gases). It’s called solar radiation management, and it includes a wide range of potential projects. And I shall now introduce you to several, starting with the most weaksauce of them, and moving on to something with giant space guns.

When I call something “weaksauce,” I don’t mean to imply that it’s a bad idea, only that it doesn’t involve huge guns, or giant sulfur-spewing zepellins. Sort of like how cool roofs are weaksauce. Cool roofs have come up on the Buzz before. The idea is that by simply having lighter-colored roofs, more sunlight and heat is reflected back away from the Earth. And, aside from the planet heating up a little less, your house heats up a little less too, so you don’t have to use as much energy on air conditioning, and the power companies don’t have to burn as much coal, etc. Pretty neat, huh?

Unfortunately, it’d be pretty tricky to get enough people to have reflective roofs for it to make much of a difference to global temperatures—otherwise the cooling would just be local, and who cares about that, right? Plus… no giant guns, or anything.

Not like the plans to build a sunshade in space. They have guns.

Remember that season finale episode of The Simpsons, where Mr. Burns built a giant metal shade to block the Sun from Springfield? I hope you do, because some scientists are actually proposing something like that, but on a larger scale, and in space. Like, massive mirrored satellites. Or there’s the plan mentioned in this Atlantic article (which I’ve linked to before)—A professor at the University of Arizona proposes building 20 giant electromagnetic guns (rail guns?), each more than a mile long, with the purpose of firing Frisbee-sized ceramic disks into space. Each gun would fire 180,000 disks a minute, 24 hours a day, for 10 years. At that point, there should be enough disks suspended “at the gravitational midpoint between the Earth and the Sun,” that sunlight headed toward Earth would be significantly scattered… lowering the planet’s temperature. Unfortunately, the technology for these guns doesn’t exist, it would be really expensive, and it would kind of last forever. Also, one gets the feeling that this professor is just trying to make a point. On the other hand… giant disk guns.

And then there are the middle ground plans, like cloud enhancement. The idea there is to make the clouds puffier and whiter by blasting seawater up into the air with special ships. These nice, white clouds would, again, reflect more sunlight away from the Earth, cooling things down. It shouldn’t last forever, and who doesn’t like puffy white clouds? Unfortunately, it ain’t cheap, and as with all most of the other solar radiation management plans, we don’t know exactly what all the repercussions would be. Clouds are just clouds, right? Yes, but clouds affect how much rain we get, and who gets it, and how much plants photosynthesize, and so forth and so forth. And the plan is slightly less gunny than the space-sunshade thing.

Next time we’ll move on to “carbon-removal projects.” But right now I have to get the taste of mouse blood out of my mouth. (It’s an ingredient in the poison.)

Victoria Gee-Treft: Victoria Gee-Treft
Victoria Gee-Treft: Victoria Gee-TreftCourtesy Science Museum
We all know and love the Science Museum, we love the exhibits, love the shows, and love the people. But who are the people that work behind the scenes and do all the work that we see through the exhibits and shows? There are tons of people that do...but one person that I find interesting is Victoria Gee-Treft. She works in development as the Campaign Gift Officer. Because of her and the prestigious team of development the museum can bring you the exhibits and the Omni shows and all the other things that you love to do. Everyday she talks to people and try's to establish relationships with current and potential donors. She says her favorite thing about her job is the people. She LOVES being able to talk to people and create relationship's with them. Her least favorite things about her job is not being able to directly talk to people. She prefers to directly talk to people...she believes that you connect more when you are directly talking to people. Shes been working in the field for 10yrs. and have been working for the museum for about 1.5 yrs. She loves her job and says she wouldn't have picked any other!

I asked her some questions in an interview I had with her and she gave me great answers. I picked 3 of the best questions to share.

Q1:Who are some important people that the museum needs to keep it “alive”?
A1:Volunteers! The museum has a great volunteer program that really benefits the museum. Other than that the whole museum needs all of it staff to keep it running. Every job has value, from the person who cleans the bathroom to the president who makes sure that the museum is at its top quality. And last but definitely not least its CUSTOMERS! The people who come here with their family or with their friends. The people who come to see the exhibits or the show in the Omintheatre. Those are the people that the museum needs to keep it ALIVE!

Q2:What kind of education or experience would someone need to get into this field?
A1:Volunteering and events. Volunteering gets you the moral part of the job, by volunteering you get to see how the people you may be talking to feel land you get to experience the whole "working for nothing" part of life which not only builds character but also shows you a whole new aspect of things. And by doing events like, races for causes or some kind of charity event you get the skill part of the job and you build the skills that you will need. For example, if you can raise $1,000 for one race in a week, just think about how much money you could raise in a month, with more tools, better connections, and a title to your name. You wont just be a "random person asking for money for something" you'll be a "corporate development executive" and you'll be asking for money that could potentially help maybe hundreds or even thousands of people!

Q3:What are some qualities or traits would someone need for this field?
A3:Patience-If you plan on going into this field or a field like it you must have patience...you have to be able to have patience with people. People want to know where their money is going and who they are giving it too. so you cant just expect to ask someone for maybe $250 and them just hand it to you. I know that if I was giving someone or something $250 i would want to know where my money was going!!

* Asking-This is one thing that you HAVE to be able to do. You have to be comfortable enough to ask a complete stranger who you have probably never saw, met, or hear of for money. I personally know people who have issues asking people for money or help. I personally feel weird asking my friends or family for money...so for me to ask a complete stranger for money would be more awkward than you could imagine. And you have to remember that your job is based on whoever you are talking to, to give THEIR hard earned money to you for whatever reason.

* Persuasion-You have to be a "people person" as someone would say. And you have to be able to convince people that they should give their hard earned money to the museum. There are some people who might be willing right away to give their money, but there are also going to be other who may need more of a convincing reason(s) to donate. If you don't find yourself a very convincing person this may not be for you.

Ever want to change the world?

No, I’m not talking about the awesome drums and bass album you’re working on. And I’m not talking about your new theory of about time and mountains and stuff. And I’m not talking about your award winning bowel movements.

I’m talking about shaking the heavenly spheres until they throw up a little. I’m talking about jamming your boot into the nearest orifice until the planet cries uncle. I’m talking about pinning its arms and slapping its belly until it forgets its own name in frustration. I’m talking about changing the world.

Sure, it’s sort of supervillain territory. And it used to be that you’d need a bad childhood and some sort of superpower, or maybe a giant laser for this sort of thing. But these days… these days you don’t even need to be super-mega-rich to tear the planet a new one; you only need to be super rich. And it could be that the planet needs a new one torn.

We haven’t really talked much about geoengineering here on Buzz, which is weird, because it falls under both “quick fixes” and “things that might look awesome,” categories I very much appreciate. This is why I prefer to deal with hangnails by shooting them off, and why my dog has painted-on zebra stripes. (The “quick fix” there was spray paint being used to make him look less stupid.)

Geoengineering is engineering on the global scale; it’s changing the planet to solve some problem. What if we could, for instance, stop global warming without changing our energy-hungry lifestyles? What if it was as quick and cheap as spray-painting the dog?

The thing is, many geoengineering projects would be quick and easy (relative to, say, transitioning the planet to renewable energy). But, like spray-painting the dog, geoengineering comes with the potential for serious problems. If we’re spray-painting the dog instead of washing him, we have to keep spray-painting him forever, or else one day we’ll have an obviously incredibly unwashed dog on our hands. And what sort of health problems might a spray-painted dog unexpectedly develop? And can we get used to living with a dog that is spray-painted?

(Bryan Kennedy posted a link to an article about these issues this summer. Check it out.)

Consider these problems with me as we turn away from painted dogs, toward the wide world of geoengineering. In the coming days, if I remember to, and if I’m not feeling too lazy, we will meet some possible geoengineering scenarios. And, remember, these aren’t totally sci-fi—they’re very possible (for the most part). The question is, do we really want to do them?

And so, geoengineering day 1: A fart like you wouldn’t believe.

Y’all know what killed the last dinosaurs, right? Yes: loneliness. But how did they get so lonely? It was that, ah, meteorite thing, right? A big space rock smashed into the Earth, boom, no more dinosaurs. But it’s not like all the dinosaurs got smashed by that falling rock. Most of the trouble came after the impact. Vast quantities of dust were thrown way up into the atmosphere when the space rock hit the planet… and it stayed up there for a while. The affect all that dust had on climate is pretty complicated, but, if we boil it way down, it basically blocked sunlight, and made the world a shadier, colder place for a while. Lots of plants couldn’t live in colder, darker conditions, so they died. And the dinosaurs couldn’t live without those plants, and so they died. (Again, it’s more complicated than that, but…)

And now… now we have a situation where, in the coming decades, the world may be getting much hotter than a lot of organisms can survive for very long. We aren’t hoping for an asteroid or meteorite to smash into us, of course, but is there another way to fill the sky with sun-blocking particles?

Yes. In 1991, Mount Pinatubo in the Philippines exploded, blasting millions of tons of sulfur into the sky. All that sulfur, and other tiny particles from the eruption (called aerosols), reflected lots of energy from the Sun back into space. Because it’s solar energy that provides the heat for global warming (greenhouse gases like carbon dioxide just trap the heat here), the Pinatubo eruption is thought to be responsible for temporarily lowering global temperatures by about 0.5 degrees Celsius (0.9 degrees Fahrenheit). That might seem like only a small drop, but a few fractions of a degree change in temperature worldwide can have a big affect on climate, and when we think about how it was caused by just one eruption… We could do it too! We could change the world!

One of the major ideas in geoengineering is to essentially recreate the Pinatubo eruption. Over and over again. Factories on the ground could pump tons of sulfur dioxide into the atmosphere, where it would bond with water vapor and condense around floating dust, blocking solar radiation from heating the planet. (This article envisions zeppelins hovering 12 miles up, tethered to factories by SO2-carrying hoses.)

The project might cost only tens of billion dollars (small potatoes when talking about changing global climate), and it might actually work… but then what? What happens once the dog has been spray-painted?

Some scientists are concerned that all that SO2 in the atmosphere could damage the ozone layer, which protects us from UV radiation from the Sun. (After Pinatubo erupted, the ozone layer suffered temporary but significant depletion.) Others point out that the project would do nothing to remove greenhouse gases, so that once the sulfur settled back down to Earth, we’d face very sudden temperature rises again; we’d have to continue to block out the Sun until we could decrease our production of greenhouse gases. The main thing that could happen is, well, we don’t totally know what would happen. It’s unlikely that a solution like this would only lower global temperatures, but exactly how it would affect other aspects of the climate and life on the planet is unclear…

Is it worth it? Should we pump the skies full of sulfur gas, even if we don’t understand everything that could happen because of it? What if it was the only way to hold off a “tipping point”? (Many climate scientists are concerned that gradual global warming will lead to a “tipping point,” after which warming accelerates rapidly. Thawing frozen tundra, for instance, might release vast amounts of trapped methane, which is a much more potent greenhouse gas than CO2.) Or do you think geoengineering would distract us from addressing the basic causes of climate change?

Any thooouuughts?

See, when I look at magazines (often), I get all frustrated that, like, the stupid things won't just read themselves at me. Like how the TV reads itself at me.

I am a busy sort of guy, and I don't have time to interpret symbols into words and words into mental images. Let's cut out the middleman, I say. That's exactly why I was so thrilled to see this announcement on the internet for an announcement in a magazine. While the first announcement had to be read the old fashioned way, wasting valuable minutes and brainpower, the latter announcement, the magazine one, will actually be in video format. It will announce CBS's fall schedule, and it will announce how delicious Pepsi is and how you should buy it. (With money, and soon.)

The magazine video uses a 2.7 mm thick LCD screen with a tiny rechargeable battery. The screen has a 320 x 240 resolution, and the chip it's on can hold about 40 minutes of video.

I was kind of thinking that the wave of the future, as far as video-zines go (my term, so hands off), would employ OLED technology, seeing has OLED screens can be super thin and flexible. But OLED displays are still way expensive, and while CBS no doubt wants to impress the New York and LA subscribers to Entertainment Weekly with their extravagance, they don't want to impress them with that much extravagance. Not for Jenna Elfman.

Um... very briefly, I believe that LCD screens work by altering the shape of a layer of film in front of a light to change the color of light that passes through that film. When the film has lots of little cells, the cells can be altered individually to make the tiny dots that form a video image. OLED screens, on the other hand, are sort of like screens made up of thousands of the little LED lights you find all over the place, except the LEDs on the screen are very very small—they're actually made of organic compounds printed on the screen, and they're activated (made to emit light) by having electricity flow to specific spots on that screen. More or less. So, once again, add lots of these little bits of light up, and you have an image. And hopefully someday some brave and proud network will put OLEDs in a magazine, to make it easier for us to learn about season 14 of two and a half men. (At that point it will be 2.5 men because Charlie Sheen will be dead, and his character will be computer animated. A half man, if you will. Or maybe the kid will cross dress every other episode.)

The Puddleduck by lightning
The Puddleduck by lightningCourtesy Rick Elkins
Ahoy! Random questions have been piling up on the poop deck of the HMS Puddleduck, and I’ve been too distracted (mostly by birds) to address them. And now… now there are so many that I can’t give them the attention they each deserve! But I will try to give them something, as quickly and succinctly as I am able. It pains me to do so, but I’ll need a more nimble vessel for this sort of mission, and so I must temporarily abandon the Puddleduck for an outboard motor-equipped dinghy and…

DING

The starting bell?! Oh man!

Q: What’s the difference between regular food and organic food?

A: It’s all about how a food or its ingredients are grown. To be considered “organic,” the food has to be produced without the use of synthetic (man-made) chemicals. So that means that organic vegetables can’t have synthetic pesticides or herbicides used to keep bugs off them and other plants from competing with them. (Synthetic fertilizers can, however, be used.) Organic meat can’t come from animals treated with hormones or antibiotics.

When a food has a sticker on it saying “certified organic,” that means that it has passed the tests of a regulating agency. In the US, a product must be made of 95% organic materials to be labeled as “organic.”

Consuming organic food might reduce your exposure to potentially harmful chemicals, but, nutritionally, organic food isn’t really a whole lot different than non-organic food.

That answer was too long. I’ll never win the lightning round this way.

Q: Do you know why there are black holes in space? Are there any undiscovered plants [sic?] in space?

A: Black holes aren’t really holes in space, exactly. You might think of them as like really really really really heavy planets. Like, when a big star gets old, it can collapse on itself, getting small, but still having the same mass. (It’s like if you were to squish a marshmallow down into a little lump. It’d take up less space, but it would still weigh the same.) Even though they’re smaller, black holes still have lots of gravity—so much gravity, that they even pull light down towards them. So they look totally black.

Undiscovered plants? … Possibly? Undiscovered planets? Definitely. There are planets outside our solar system, but they're too small and far away to actually see. But there are other ways of detecting them, involving how a planet affects the way we see its star. But I can’t get into that, because this answer is already too long too.

Q: Have you found a dinosaur as big as a jumbo jet?

A: Me personally? No. Other people? Yes. Or… just about. So, the original jumbo jet, the Boeing 747 is about 70 meters long, and it weighs about 400,000 pounds empty The long necked, long tailed sauropod amphicoelias may have been about 60 meters long (196 feet), and it could have weighed as much as 135 tons. (That’s 270,000 pounds.) Not quite as big as a jumbo jet, but near enough that I think it should get the title.

Q: Why is the sky blue, and not green or black? It looks black from outer space.

A: The sky is blue because of all the methane gas in our atmosphere. The light reaching our planet has all wavelengths of color mixed together, but certain gases scatter certain colors more than others. Blue light gets absorbed by methane molecules and then scattered around, making the sky blue wherever you look. If you were to look at the sky from the moon, yeah, it would look black. That’s because there’s no atmosphere on the moon. No atmosphere, no gas, no gas, no light scattering. No blue. It’s explained better here

Q: Is your hair alive? If not, why is it always growin?

A: Nope, not alive. No nerve, no blood vessels, no activity. It’s always growing because structures in your skin called hair follicles are always making more of it. It’s like… like a string factory, making one long piece of string. There’s stuff happening in the factory, and the material the string is made of might once have been alive, but the string itself isn’t.

Q: How old is the oldest person in the world?

A: The oldest living person is Gertrude Baines. She’s one hundred fifteen years old.

Q: Where was the biggest snake that ever lived?

A: Columbia. 60 million years ago. Titanoboa cerrejonensis is extinct now, but it is estimated to have been about 42 feet long and 2,500 pounds.

Q: How long were the dinosaurs alive?

A: Dinosaurs lived during the Mesozoic Era, which lasted from about 251 million years ago to about 65.5 million years ago. The first dinosaurs didn’t appear until the late Triassic period, though, and that was about 230 million years ago. That means dinosaurs were around for about 165 million years, give or take a few. That’s a looong time, especially when you consider that humans have only been around about 2 million years (and, really, we modern humans have only been around for maybe 200,000 years.)

Q: How long can turtles live?

A: Oooh. I like this one. Large tortoises have been known to live well into their second century (one in a Calcutta zoo was actually reputed to be around 250 years old, but it died a few years ago). But how long could they live? Most animals (including people) start to automatically break down after a certain period. Cells don’t regenerate like they used to, and organs slowly deteriorate and fail. But turtles… apparently this doesn’t happen to them. They don’t seem to have this automatic shutoff built into them, so they don’t age like other animals—a hundred-year-old turtle could have organs as fresh as a teenage turtle. Unfortunately, they can still succumb to disease, or predators, or Foot Soldiers, and eventually the odds add up and they die. From something. Neat though, huh?

Q: How do you tell butterflies and moths apart?

A: Moths tell only secrets.
Butterflies tell only lies.

Q: Where do elephants live?

A: Africa, India, Sri Lanka, Nepal, China, Southeast Asia, Sumatra, Borneo. And maybe some other places. And zoos.

Q: What are hiccups made of?

A: Hiccups are caused by the diaphragm muscle twitching spasmodically, causing your lungs to suck in air so quickly that your epiglottis (a little thing in your throat that keeps you from breathing in the food you swallow) snaps shut, halting the breath. But what are they made of? Babies’ dreams.

Q: How many explosions have you made while working.

A: It depends on your definition of “explosions.” Somewhere between zero and thousands.

Q: Does the science museum ever get boring?

A: No. Never. I have the scars to prove it.

Q: Can people put rabies in guns and shoot us with it?

A: Probably not in a normal gun. When a bullet is fired, it becomes very hot, and I think that could destroy any rabies viruses the in the projectile. But rabies is generally transimitted through saliva, so I wonder if one could put a sample of contaminated saliva in a ballistic syringe and fire it from a tranquilizer gun. It seems reasonable. I’d watch out for this, if I were you.

Q: Why do people cry?

A: Because living in the world can be very difficult and painful, and the frustration at our inability to cope with this sometimes manifests itself in our lacrimal apparatuses going bonkers.

Q: Do you catch snakes?

A: Not frequently, but sometimes, yes. In my last house, I had lots of holes in my bedroom floor, and sometimes garter snakes would come into the room through those holes. Considering how my room was on the second floor, I figured making the trip up to my bed wouldn’t be a big deal for them, so capture and release was necessary.

Here’s my fail-proof snake capturing strategy:

1: Spot snake in bedroom
2: Retrieve used pair of underwear from bedroom floor
3: Throw underwear over snake
4: Grab snake and underwear
5: Go downstairs, throw snake outside, keep underwear

This method is nice, because it temporarily gets rid of snakes, and it sends across the message that anything you don’t want in your room is going to get hit with your undies. (Some snakes, though, are perverts, and this may backfire on you.)

DING!

Hmm. That was a pretty weak lightning round. Real lightning is way faster than that, and it makes a stronger point. I’ll keep practicing.

Until next time, Buzzketeers, always keep dirty underwear on your floor, and not in your hamper, just in case you need it for snakes.

Get your bells out, everybody, and ring them! The Chevy Volt is here! (In a year.)

GM released new details today about its new gas and electric hybrid car, the Chevy Volt. Using a plug-in battery (as opposed to current, unmodified hybrid cars, which recharge only via the gas engine), GM claims that the Volt should be able to achieve approximately 320 miles to the gallon during city driving. Estimates haven’t been completed for combined city and highway driving, by officials are confident that fuel economy will remain in the triple digits.

The car should have a range of about 40 miles, using its battery alone, at which point the gas engine would kick in. Nearly 80% of Americans, however, commute less than 40 miles each day, so most of the expended energy could come from the electrical grid (the car will plug into a standard outlet), instead of from gasoline.

GM’s chief executive calls the Volt a “game changer.”

Finally, a game-changing American car. Not like those sissy Prius drivers, making smug environmental statements by purchasing impractically expensive vehicles. Sure, the Volt will be entering the game about 9 years late, but it does so with the confidence that every environmentally conscious working-class American with $40,000 to drop on a sweet new car will… wait, what?

What about the rest of GM’s 2010 lineup? They’re cutting more than half of their 30+ mpg cars? But a few Volts on the road should bring that fleet average up, right?

And GM is pushing for environmental responsibility in other areas, at least, right? Oh, they’re pulling out of a partnership that collects toxic mercury from their old scrapped cars?

Well, it was a nice thought. And it’s comforting to hear someone say something like “game changer” now and again.

Update:
Weeellllll... it looks like the volt may be kind of an unremarkable car after all. Despite their claims last year that it would get something like 230 miles to the gallon, auto trade magazines are test driving it now, and saying it actually gets mileage in the 30 - 40 mpg range. That's less than a Prius. But don't worry, it's still super expensive. Huh. I mean, I couldn't design a "game-changing" car, but, then again, I never said I would. It turns out, too, that even though GM insisted that it wasn't really a hybrid car, and that the gasoline powered engine would only drive a generator for the battery... that's all not true. The gas engine does charge the battery, but it also will drive the wheels. Prove me wrong, Chevy (or commenters), but is this actually a crappy idea, and not a significant step towards changing our energy use?

Usually it's the fan that chases the band around, checking up on its every move, emotionally connected to the music and members. But, have you ever heard of a band obsessed with its fans? So much so that it constantly checks up on its popularity and changes its music based on its mood. On top of that make it a robot band. Yes, a musical robot with feelings...

This self-conscience robot is called the Cybraphon. It was built by three musicians in an antique wardrobe using instruments, motors, and a computer. Checking in on websites such as facebook and twitter, it counts hits and compares the usage over a one to two day time frame. Using this information it calculates its popularity and adjusts its mood appropriately, displaying it on a 100 year old galvanometer.

The interments in the wardrobe include an organ, cymbals, and all the way from India, a Shruti box. All of the instruments have been modified to be played electronically using motors and solenoids. If the robot is in a good mood it can be heard playing an upbeat tune. Vice versa, in a lonely mood the music will be slow and sad.

Not only is this robot picky about its social standing but even though it is always on it will only play it's music aloud if there is someone to hear it. Using infrared sensors the robot will start to chime whenever there is an audience to listen.

Cybraphon is going on display in Edinburgh, Scotland starting on Aug. 5th. You may not be able to go see it for yourself but, you can track it's progress and boost it's ego on twitter, myspace, and facebook.
