MakesThingsGo - > Makes Things Go -> Scum of the Earth
Scum of the Earth

Pete’s comment the other day about churches tapping into the power of God by way of renewable energy got me to thinking about writing up another bit on some of the stuff going on in the realm of renewables.  One of the exciting developments that is just getting started is using algae to produce oil.  My understanding is that plenty of the oil we use now was originally pond scum anyway, so all we’re doing is shorting the life cycle.

Of course, in order for it to be profitable, the algae have to be farmed either in open ponds or in enclosed tubes.  In order to speed their growth, CO2 would be pumped into the air.  The algae absorb the CO2 which is released when the fuel is burned.  This is an example of being “carbon neutral”, since the technology uses already airborne CO2 and captures it for work before re-releasing it into the atmosphere.  Another benefit of this idea is that it uses the existing infrastructure including standard oil refineries to process the algal oil and can be turned into jet fuel, diesel, and gasoline.

A lot of the CO2 could also be tapped from industrial sites that would vent it into the air anyway, which is a benefit in that you’d take a purely waste product and reconvert it to energy for another cycle.

There are still engineering problems to overcome, including the desire to genetically modify some of the algae to optimize oil output and protect the farms from being taken over by invasive species.  The idea has been around for a while, but wasn’t economically viable when oil was at 20 dollars a barrel.  With 50 dollars a barrel seeming to be the floor and instability in the Middle East driving it to 80 dollars a barrel occasionally, things like this make sense.

I'd told Robb I'd post on 3-way switches this week, but people don't seem to interested in nuts and bolts type columns.  Either that, or everyone's houses have been behaving, which I find hard to believe.  I'll be in and out today, but I'll get back to everyone if you've got some home repair stuff for me this week.

And for Robb: http://www.wfu.edu/~matthew... That's right, baby, an animation of how 4 way switches work.  :)

I've read a number of sci-fi novels that have algae pools as a common source of energy and food (when you grow fish in them that eat the algae). Earth by David Brin was a great view into a "green" future. (BTW: I'm not sure that the CO2 acceleration plan is all that smart for this. I'd much rather have larger pools than burning fossil fuels for faster growth.)

Better still, see his "Heaven's Reach" trilogy for a picture of a society which deliberately makes as little a "footprint" on their world as possible, up to and including designing solar-powered non-digital computers...

.

Maybe we should start looking for some catalytic process that takes atmospheric CO2 and turns it into lampblack to be packed back into the coalmines...

I think I've heard of things like that Random. I've come up with a prototype for that concept, but I still need a few million for further R&D. Here's what I've come up with so far:

Hey Tom,

I'm getting a broken link error message on that link. Don't know if it's just me or not. Thanks in advance when I can get there!

Sorry about that, Robb.  This one should work:  http://www.wfu.edu/~matthew...

Mattloch, that was my issue with this.  I don't think they plan to burn additional fossil fuels, just hook up to the exhaust systems of existing plants.
posted by mattloch on Feb 7, 2007 at 02:37 PM
At the very least, existing plants should have to build these as carbon offsets. Not necessarily on the same property, but somewhere nearby, within at least a few hundred miles. Was there a specific type of algae that they mentioned in articles you've read Tom, or was it used generically as something to be chosen at a later point? (In other words, is it the discovery or creation of a specific algae strain that drove the article, or the concept of carbon sinks to be used for fuel creation?) I'd be interested if you had specific articles or books, since environmental topics show up every few years in the debate community, and I'd like to be working on resources for my boy to tap when he hits high school...

Mattloch, I've read a few articles lately, most recently this: http://www.technologyreview...

Of course, the Google is nice too.  "algal oil" turns up good hits including companies that do it.  http://www.google.com/searc...

You debate geeks.  I hang out with a couple of guys who coached debate.  You're like stamp collectors with facts.

Sweet, thanks for the links Tom. I've been "retired" from debate for about 7 years, and my buddy has been out for a few years as well, but we still read through books and magazines like we were prepping for a tourney this weekend. I'd rather know too much than too little, and I just love reading about something that I've never hear of before. Obscure quarterlies and studies are much better than mainstream media for information, anyways. As long as you keep your "bs" radar on, you'd be surprised how far ahead of the curve you can get on a developing news story or world event. We've read stuff that has taken months or years to be picked up by the MSM. It can be fun to answer the news anchor's question better than their "expert" when you watch one of their shows, or read an interview.

Mattloch, another article popped up through my RSS feeds. http://www.worldchanging.co...

This one talks about mostly the same stuff but mentions that one algae plant is using the CO2 from a brewery.  I think I may have just found my calling in life.

Sweet, RF.  I saw some old gastrobot technology that reminds of the refuse collector.  I think it was a lawn mower that ran on grass clippings or something.  Here's my question: Do we really want to start making machines that run on organic matter?  Only a matter of time before a quantum gastrobot decides we'd make a tasty snack.

Sweet googly moogly, Random. I read about the Bose-Einstein condensate back in '98 when they did it, and wondered what they could do to top it. Looks like they succeeded. The quantum computer article is pretty damn cool as well. I've been waiting for one of those to come out for a while. Once they get a real working one, things like "transporters" become possible, and perhaps even probable. Too bad the reactor isn't a real "Mr. Fusion", but instead a "Mr. Bioreactor". I read about them making something like that to handle the wastes from a chicken processing plant a few years ago, turning the waste into oil in a manner similar to how we create artificial diamonds compared to how the Earth does it. Play around with the temperature and pressure enough, and you get it in a few hours or days instead of millennia. Using it to destroy Top Secret information is a pretty silly use. The highest-end shredders we have and use already pulp the paper. Unless you have a quantum computer you couldn't reassemble the pulp back into the paper. . . . . . oh yea. Never mind.

What is that line from Mattloch? Sweet googly moogly..it rings a bell in the back of my lil head.
posted by GrpThink on Feb 9, 2007 at 03:09 PM

Great Googly Moogly is a phrase which has been used in popular music lyrics (particularly Rhythm & Blues) by various artists dating back to the 1950s [1].

Known examples include Frank Zappa's Nanook Rubs It (1973) and Howlin' Wolf's recording of St. Louis Jimmy Oden's Going Down Slow (1962). There is some evidence (unverified) of earlier uses by other musicians:

At the very least, R&B legend Screamin' Jay Hawkins uttered it as an exuberant exclamation of extreme excitement in "Person to Person" (1957): the line in question finding SJH extolling his far-away (cheerbabe?) girlfriend to "bring your big fine foxy great googly moogly lord-look-at-that self on home." I’ve got some vague recollection that SJH used the phrase in other tunes – and I know Mojo Nixon and Skid Roper lovingly borrowed it on a track or two of their first few albums in the mid-1980s.

Correct Grpthink. Also from a Snickers commercial.

I remember it from Zappa.  The first true crazy man of rock.
posted by TomW on Feb 10, 2007 at 09:08 PM
Mattloch, the process you're thinking of with the chickens is thermal depolymerization.  They tossed everything from the farm in there that didn't go to the store and turned it into oil, water and a few other things.  I think it can up when we were talking about the sludge that gets dumped here from LA.
posted by mattloch on Feb 12, 2007 at 10:05 AM
That's it, Tom. What's the difference between that and the process described in Random's (linked) article? High temp, low pressure, low oxygen process.... BTW, small but sweet article here about Toyota's newest "concept" car that's been making the rounds to the North American auto shows. 0-60 in 4 seconds, hybrid engine, possible replacement to their Supra. Best of all, they claim it'll cost $35k! Sign me up!!!
posted by TomW on Feb 12, 2007 at 12:51 PM
Very nice, Mattloch.  For me, I'd rather have some cars geared towards milage rather than horsepower, but I guess I'm not typical.

I think the difference is that thermal depolymerization uses organics mostly and pressure.  The gasifier seems to just melt stuff down.
posted by mattloch on Feb 12, 2007 at 03:08 PM
I couldn't tell if it was changing temperature for pressure, or if it was a fundamentally different process.... I'm interested in the ultimate efficiency of the car, too. But there's nothing wrong with tossing a few high-capacity capacitors in there to give you a fun little "turbo boost", and recharge them with brakes as well as batteries. The fact that it looks like something out of I Robot or even Blade Runner doesn't hurt at all.....
posted by TomW on Feb 12, 2007 at 03:28 PM
That car is sweet looking, Mattloch.  You could definately get people to drive it just for the look.

I'm not sure if that is right about the heat vs. pressure.  I'll poke around some more tomorrow and see what I can come up with.
posted by mattloch on Feb 12, 2007 at 04:41 PM
I was basically using the analogy of making diamonds; you've got three variables: time, pressure, and temperature. You can increase one and decrease one (possibly two) others, depending. No need for you to spend any time on it, I was just asking if you knew how making oil would be that different (in the variables) than making diamonds.   ...As for the car, there are a few very small electric car manufacturers that are making that trade-off, because very few people need an electric car that goes several hundred miles between charges. Most people need a hundred or so, just to be safe. They're trading in distance for speed, in a big way. Some of the smarter manufacturers are looking to computer (laptop) battery technology as the next step. Why spend time and money doing research that's already been done? These second-generation hybrid and (long awaited) second-generation electric cars will start making decisions based on consumer whims, not just engineering ones. I'm just waiting for the third- and fourth-generation cars; they'll start making self-contained chassis, and let the rest of the car be made by "coach-builders", just like they did a hundred years ago. Those cars will be truly unique. Hopefully we'll see a renaissance of custom car building, not unlike what motorcycles have been going through these past 5-10 years.
