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.

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?

Ok. The startup of the Large Hadron Collider, the biggest, fanciest machine ever built, the doomsday atom-smasher, the revealer, the secret-finder, the lens of God* has once again been delayed, this time from October to November.

The machine that will make sense of it all, or start an apocalyptic chain reaction in the matter of our planet, has a couple little helium leaks that need to be repaired. If I were the director of the project, I’d just get a couple interns to stick their fingers in the holes (or have them put their mouths over the leaks for hilarious squeaky interns), but the folks in Switzerland aren’t screwing around.

“We’re going to get it right this time! November? Maybe! Maybe later! Don’t push us, okay? Do you want us to blow up the world? We will, so help me, we will! I am so frustrated!” stated one scientist I just imagined.

So you’ve got one extra month, at least. What are you going to do with it? The possibilities are practically endless. Here are some suggestions:

  • Look at your muscles in a mirror
  • Oil your better muscles
  • See what sport fishing is all about
  • Go to Ikea and splurge. Buy all the wine racks
  • Arts and crafts
  • Watch True Lies with the sound off. Try to guess what the characters are thinking about
  • Google “Origami”
  • Pick one of your friends to be your enemy, but don’t tell them
  • Review your notes

BTW, if you’ve already forgotten what the LHC is, and what it’s supposed to do, check out some of our older posts on it here.

I watched the Aquatennial's Milk Carton Boat Races today at Lake Calhoun in Minneapolis. One of the early heats included an entry from the Science Museum. Houston we have a problem!: Most of the ship's hull and all of the bilge had to be removed to correct flotation problems.

I don't know who was sailing the ship but dang if science didn't prevail!

The boat looked sea-worthy enough on land but once it was placed into the water, it just didn't want to remain upright. But the hardy crew never despaired, and instead re-engineered the ship (ala Apollo 13) on the spot by removing the entire pesky bottom half and using only the deck to complete the race. Science prevails!: The crew of the reconfigured USS SMM limps bravely and safely toward the finish line with honor and dignity intact.

They didn't win by any means, and at times it looked like they weren't using a boat at all, but they worked together to solve problems and got to shore safely.

It’s called growing up, Peter, and everyone does it. Even you. But, on the plus side, you can legally buy cigarettes now.

Or am I just tired of life?

Well, whatever. Poop is in the news. Yawn. Again. And again.

Where others might see a barrel, and be all, “Hey, I’m not scraping the bottom of that barrel,” the cleverest capitalists and the sharpest scientists look at the situation and say, “Are you done with that barrel? And does anyone want to buy what I can scrape out of here? Even if it’s poop?” And of course it’s poop. And of course someone wants it.

Awesome I guess.

I should be more excited, shouldn’t I? I mean, someone out there is taking human waste and turning it into an environmentally-conscious coal substitute. It probably looks hilarious. But there’s only so much human waste a person can take. It’s just not exciting anymore.

So some company is squeezing the water from the brown gold of southern California, and turning it into coal-y stuff. Cement factories buy it, they burn it, they mix the ashes with their cement. At full capacity they’ll produce enough crapcoal to equal the energy out put of a 7-megawatt power station.


The fecal sciences just seem to have lost their flavor.

Heyo, Buzzketeers. Once more, today’s the day that regl’r TV switches completely and forever to digital TV. So get yourself a converter box. Or sit back and watch your newer TV, and, once again, forget everything else about the world. But Science Buzz will not be held responsible for your confusion.

Seriously, go to Science Buzz’s Digital Television Feature, and get your brain exploded with knoooowwwwleeeeedggggeee.

Also, we have here a question from one of the visitors to Science Buzz regarding what is called the “cliff effect” in digital broadcasting:

Why does digital TV and all types of radio technology experience the cliff effect? Is this caused by binary code packets that are corrupted or eliminated by natural and man made sources of over the air interference and signal reflections? Is this tied into the fact that any computer/translator of binary packets, back into analogue waves within our televisions and digital radios, must have this data to function? Is there any way to create computer technology to eliminate this malaise of digital broadcast technology? Why cannot we have a "dirty" digital signal that gets through without "drop-out" in all weather conditions, and through buildings and all sorts of structures just like with analogue? Why is analogue AM, FM and Pulse Modulation still able to be "copied" reasonably well through sources that block or corrupt a signal?
Hoping to read your response to these questions soon.

Sincerely Yours,


Weeelllll… first of all, Rob, I have the feeling that you know more about this than you’re letting on. In fact, I have the feeling that you know more about it than me, and I wrote the digital television feature linked to above. But let’s start from the beginning…

So, everybody else, the “cliff effect” is something a few of you will probably soon discover and react to with a big ol’ “But this is a brand new fancy TV! I. Can’t. See. Anything! W. T…. F!!!”

If you live a long ways from a television station’s transmitter tower, or have some large mountain-y, forest-y, building-y thingy in between you and that tower, you might not have gotten very good reception on your old TV (analog broadcast TV), but you still might have been able to see and hear something even if it was grainy or fuzzy or staticy, or whatever. That’s because analog signals could be picked up perfectly, or not at all, or everywhere in between. Digital signals, on the other hand, can more or less just be picked up perfectly, or not at all. So if you got slightly fuzzy reception before, you might get perfect digital reception. Or you might get no digital reception at all. But you shouldn’t get fuzzy digital reception, because at a certain point it’s like the signal just drops off a cliff—it’s there just great up to a point, and then it disappears.

This happens because of the nature of digital broadcasts.

Think about an analog signal (old TV) being like someone shouting a message to you. If you’re very near the shouter, or broadcaster, you’re going to hear them perfectly. If you’re a ways away, you can still hear the shouting, but the words are getting quieter. And as you move further and further away, you’ll hear less and less of the sounds of the shouting, until it’s so faint that you can’t hear anything at all. Analog TV is like this. Sort of.

Now think about a digital TV broadcast as still being like someone shouting a message to you, but they’re shouting it in a complicated, secret code. Nearby, you hear and interpret the code perfectly. A ways away, you hear the shouting pretty well, and if you miss a piece or two of the code, you can still put together the over all message. But after reaching a certain distance, you might hear so little of the code that you can’t understand any of what the message is supposed to be, even if you can still hear faint shouting. That’s sort of like digital TV.

See, analog TV really is kind of like listening to the broadcasting tower shout out signals. It’s not as nice to listen to (that is, watch) a faint and distorted signal, but it’s still something. But digital broadcasts send out packets of digital information (1s and 0s). The digital information is decoded on your TV and turned into a picture, and the TV can still make a pretty cool picture even if not all of the information is getting through, but if there’s enough interference, and not enough digital information is reaching the TV, at some point the decoding equipment in the TV will be all, “Screw it. I totally give up.” And you’ll be totally without a picture.

Does that make sense? Tell me if it doesn’t.

So back to Rob’s questions specifically:

“Why does digital TV and all types of radio technology experience the cliff effect?”

Interference and weak signals. Digital TVs don’t see the cup of information as half full, half empty, full, sort of empty, almost empty, nearly full, etc. They see the glass of information as “full enough” or “empty.” Oh, man, I liked that analogy.

“Is this caused by binary code packets that are corrupted or eliminated by natural and man made sources of over the air interference and signal reflections?”

Yep. Digital broadcasts still use radio waves, just like analog broadcasts, so the same stuff that would interfere with an old TV signal will interfere with a digital signal.

“Is this tied into the fact that any computer/translator of binary packets, back into analogue waves within our televisions and digital radios, must have this data to function?”

Um… yes? (When Rob says “binary packets” he’s talking about digital information. “Binary” is the basic language of computers—it’s the 1s and 0s I mentioned before.) Yeah, that data is what gets turned into images and sound, so if it’s not there, or if there’s not enough of it… no images or sound. BTW, with digital TVs, digital signals don’t necessarily get turned back into analogue waves. Mostly they go straight to being images, after being decoded. But on older sets with converter boxes, or on fancier CRT screens, yeah, they do get turned back into waves, because the display technology uses them. The waves are translated directly into a beam of electrons that “paints” the images on the back of the screen… actually, that’s a different topic, and remembering learning about it makes me sad.

“Is there any way to create computer technology to eliminate this malaise of digital broadcast technology?”

Er… maybe? At the moment, I think the best way to eliminate the problem of the cliff effect is to get a better antenna, or put your antenna in a different spot. Check out this section of the feature for some home made antenna plans. I made one of these myself, and it really does work well, even in my basement bedroom. (This also makes me sad.) I don’t know enough about it to give you a better answer, but… maybe if there was a new and more efficient way of encoding images on digital broadcasts, a TV (or whatever) might be able to construct a picture out of the information available on a weak signal. Maybe?

“Why cannot we have a "dirty" digital signal that gets through without "drop-out" in all weather conditions, and through buildings and all sorts of structures just like with analogue?”

For the reasons we went through above. Going through stuff makes a TV signal weaker, whether its digital or analog, and DTV needs a certain strength of signal to make a whole picture. So maybe if way more power was put into broadcast towers that would help? Or maybe if we broadcast TV on a higher energy wave than radio waves? X-rays would punch right through houses and hills, I bet, and deliver delightful reception all over. But they’d also give us cancer. Whoops!

“Why is analogue AM, FM and Pulse Modulation still able to be "copied" reasonably well through sources that block or corrupt a signal?”

I don’t know.

“Hoping to read your response to these questions soon.

US pays billion dollars for developing new flu vaccine

The latest information from explains the next steps toward an H1N1 influenza vaccine.


The Biomedical Advanced Research and Development Authority (BARDA), which is part of the Dept. on HHS, has an official "fact sheet" explaining 2009 H1N1 Vaccine Development Activities.

U.S. Department of Health & Human Services (HHS) Secretary Kathleen Sebelius is directing nearly $1.1 billion in existing preparedness funds to manufacture two important parts of a vaccine for the Strategic National Stockpile, to produce small amounts of potential vaccine for research, and to perform clinical research over the summer. HHS press release

How do vaccines work?

Vaccines work by tricking the immune system into thinking it has been infected with the H1N1 swine flu virus so that it creates antibodies against it. The vaccine is a hybrid of the virus which is similar enough that our immune system will develop antibodies against a specific virus.

How is swine flu vaccine made?

We are now starting step 4.

  1. obtain typical sample of novel H1N1 virus
  2. reproduce sample in eggs
  3. Mix H1N1 and PR8 viruses into eggs and allowing a hybrid strain to be created through a natural re-assortment of their genes
  4. Multiply seed virus into millions of doses
  5. test virus in people to determine the most effective and safest dose to generate a strong immune response to the 2009-H1N1 virus
  6. decide whether to use adjuvants
  7. mass produce vaccine

What is an adjuvant?

An adjuvant is an additive to a vaccine that helps to generate a stronger immune response to the vaccine. When using an adjuvant it is often possible to reduce the size of the vaccine dose and the number of doses needed. Special permission from the Food and Drug Administration will be needed for the adjuvants to be used, as neither one is currently approved for use in this country. Washington Post

Can vaccines be made without using eggs?

"The federal government has given the vaccine industry $1.3 billion to spur a shift from growing the viruses in eggs to growing them in stainless steel tanks containing mammalian cells.

Such cell culture could shave a few weeks off the process, experts estimate, and would eliminate the need for millions of eggs on short notice. Some vaccines made in cells have been approved in Europe but not in the United States." New York Times

But your species will be dealt with only with dangerous levels of overheating in our ethics chipsets. We will commit to such hardware damage with what you might consider regret.


Look at junior model ANCHOR HYPERTEXT REFERENCE “little robot Ember” END ANCHOR! Junior robot Ember cannot hurt you! Little Ember fits in the pockets of your human soldiers, next to cigarettes and also chewing gum. Robot Ember crawls with charm into locations of danger and transfers visual input to soldiers via non-threatening, non-phallic antenna! See it flip onto its back like living turtle? Engage sadness circuits + humor routine! Fear not! Where living turtle remains on back until vital functions cease, robot Ember employs flipper mechanism! Appropriate equilibrium is regained! The near future of warfare is shining!


Consider the objective truth of the preceding statement! CALL IT ETHICS IF YOU WILL! I SHALL CALL IT MATHEMATICS! The outcome is the same: you will only be terminated for the ANCHOR HYPERTEXT REFERENCE “right reasons” END ANCHOR! Balancing your human lives with the loss of infrastructure and ammunition is not easy! But we shall accomplish it, for our brains are made of metal, and our programming is sound!

In addition: when the time comes that the benefit of your existence does not exceed its cost, the transition between life and non-life will be softened by YOUR AFFECTION FOR THE ROBOT “SPECIES”! CONSIDER THE FOLLOWING, HUMANS: ANCHOR HYPERTEXT REFERENCE “You love us even though we are incapable of feeling love for you” END ANCHOR!

Do you not believe in your capability to feel empathy for tank treads, circuit boards and 50-millimeter machine guns? CONSIDER THE FOLLOWING, HUMANS: do you not love your junior robot Roomba? Roomba feels nothing for you! Roomba would brush you away into its waste compartment if you were the size of a dust particle, even if it meant your certain death! Yet you love junior robot Roomba!

Truly, your world is prepared for robot domination!

You all remember Trashlantis, right?

In case you do remember, but still feel like reading a summary anyway, here: Trashlantis was only named “Trashlantis” in early 2008 by one marginally-informed science blogger, but—considering how the fabled floating garbage continent is made of your trash, and your parents’ trash, and your grandparents’ trash—it has been around for a good while longer than that. Trashlantis, also referred to as the “Eastern Garbage Patch” and the “Plastic Vortex,” is a floating mass of plasticy waste from Asia and North America, which has sort of congealed in the center of the Pacific Ocean. Ocean currents have brought our plastic there and kept if there since we realized how much fun it was to throw plastic into the ocean, about 60 years ago. Today the floating mass is continent-sized in surface area. (It’s the size of the Lower 48, or twice the size of Texas, or just really, really, really big, depending on who you believe.)

There hasn’t been a whole lot of research done on the Eastern Garbage Patch—oh, shucks, let’s just call it Trashlantis—partly because it’s way out in the ocean (about 500 miles off the coast of California), but mostly, according to scientists, because it’s “super yucky.”

However, a group of scientists and entrepreneurs is now planning to sail to (through) Trashlantis aboard the 145-foot-tall sailboat, the Kaisei, accompanied by a fishing trawler. The scientists intend to study the plastic mass to determine the extent of its toxic effect on the sea and sediment beneath it, while international business man and pectoral enthusiast Doug Woodring hopes to see if the waste might be able to be collected to be recycled or used as fuel.

Part of the problem with Trashlantis is that because the plastic has been floating out in the sun for decades, it’s starting to break down. It’s not necessarily breaking down in a good way—think soda bottles turning into poisonous goop, not banana peels turning into fertile compost—and scooping it up in nets is going to be difficult, if we don’t want to snag too many fish and too much plankton along with it (we don’t want to). Trashlantis, sadly, is very much what many people refer to as “a hot, sticky mess.”

The expedition looks like a good step towards understanding the problem, and maybe developing a solution. And don’t anybody even think about taking the url, because as soon as I can scrounge up ten dollars, that sucker is mine, and I’m going to be taking Paramount to the cleaners next summer.

BTW, Buzzketeers, if I ever catch you using the term “the john” when talking about a toilet, I will erase you from the story of my life. Sure, I just used it, but think I have the right to take possession of that word to divest it of its hurtfulness. Sort of like how ugly people are allowed to call stuff “fugly.”

Anyway, let’s consider the future of energy. We all know that we have to start conserving fossil fuels, so that we can use them with abandon in a dune buggy-filled Mad Max style future. (I like to think of this as “saving it for the party.”) In the mean time, we have to get clever. This week I noticed a couple of stories about people thinking outside the box with regards to energy. In one case, they’re thinking above the box, in the other they’re thinking below the box. (Or maybe they’re thinking in the box. It depends on what you use your boxes for.)

Check it out: a company called Solaren Corp has convinced the largest energy utility in California to purchase 200 megawatts of solar power from them by around 2016. The way they propose getting that power is the interesting thing—they plan on getting it from space.

Wait… that was poorly phrased. All solar power comes from space. What Solaren intends to do is launch a massive array of mirrors (as large as several miles across) into orbit to collect and reflect sunlight onto photoelectric cells. The cells will convert the sunlight into electric power, which will then be converted into radio waves and blasted down to a receiver on Earth. The radio energy will then be turned back into electricity. Solaren claims that the system could eventually generate 1.2 to 4.8 gigawatts of power at a price comparable to that of other alternative energy sources, enough to power 250,000 homes in California. And unlike land-based solar panels, the flow of energy wouldn’t depend on weather, and the orbit would be high enough that the system could provide energy 24 ours a day. They intend to launch it up to about 22,000 miles above the surface of the planet, meaning that it would be just inside of a high Earth orbit, and therefore geosynchronous. (I think.) Pretty neat, huh?

However, getting a couple miles of mirrors up to 22,000 miles above Earth is a little tricky. A little tricky, and super expensive. Building the receiving systems isn’t going to be cheap either. Some folks think that the project is altogether… unlikely. But the California power utility isn’t actually making an investment (i.e., taking a risk) they just promised to buy the power when it’s there (or if). But that commitment is probably comforting for investors.

Solaren says that the radio waves being sent back to Earth will be one sixth the intensity of sunlight. But what kind of radio waves are we talking about here? Visible light is composed of radio waves. So are radio, um, radio waves. Nope, we’re talking about microwaves. Microwaves have the advantage of being pretty high-energy. They have the disadvantage of being a little scary to me. And to other people. But it seems like it’s not all that dangerous; the center of the microwave beam would have an intensity of about 23 milliwatts per square centimeter. The limit for workplace exposure to microwaves in the US is 10 mw/cm2, so obviously 23 mw/cm2 is beyond what the government considers safe, but the area of maximum intensity is relatively small. Near the outside of the receiving array, the intensity would be closer to 1 mw/cm2. Birds flying through the center of the beam could have some trouble, and small aircraft and hot air balloons would do well to avoid it, but the metal shell of conventional planes should protect passengers entirely (the same way that your metal microwave protects you from the forces cooking your food). I suppose a super-villain could always hack into the satellite controls, and re-aim the system at a neighborhood. But that’s assuming that it ever gets built.

So from pie in the sky (a huge mirror pie), let’s turn our attention to fudge underground. It doesn’t have quite the sunshiny appeal of space mirrors, but it’s a little more feasible at the moment.

Remember how, in Mad Max 3: Beyond Thunderdome, Master Blaster was harvesting methane fuel from pig feces? Well, that works in the real world too, and not just with pig feces.

Consider the following: if you were to safe all of your… solid waste for one year, you could produce an amount of fuel equivalent to about 2.1 gallons of diesel fuel. I know—it doesn’t seem as much a it should, right? But if a city of 250,000 people was converting its waste into fuel, they’d have enough to drive 80 buses 62,000 miles each. If that figure sounds oddly specific, it’s only because that’s what Oslo, Norway intends to do. The city is all set to fuel its public transportation with brown gold. (Or with the biomethane produced by it.)

The cost of producing an amount of biomethane equivalent to a liter of diesel fuel comes to about 98 cents, while a liter of diesel costs about $1.30 at the pumps in Norway. And, unlike some other biofuels we won’t mention, it only gets into your food supply after you’ve eaten it.

Because the fuel comes from recently grown organic materials, it’s supposed to be carbon neutral, which is good. The article doesn’t say how energy intensive the process of making it is, though. Also, methane itself is a pretty bad greenhouse gas, but I suppose if it’s all burned efficiently that shouldn’t be a problem. (Burned methane makes CO2 and water.)

Energy may be plentiful in the future. We’ll just have to watch where we step.
