Bacteria Powered Batteries

Agent Provocateur writes "SpaceDaily reports on a battery that is powered by chemical reactions caused by bacteria. A Pentagon-backed project, University of Massachusetts researchers Swades Chaudhuri, an Indian, and Derek Lovley, an American, say the battery's source is an underground bacterium that gobbles up sugar and converts its energy into electricity. Their prototype device ran flawlessly without refuelling for up to 25 days and is cheap and stable." The chemistry behind this thing isn't really that complex - keeping the bacteria alive and kicking during that time is prolly the tougher part - you can read more on Al Jazeera, and USA Today. Now, what about replacing this battery?

      I suppose where you live as to the % you get out of a car engine - manufacturers figures are usually very optmistic.

      You're not talking about efficiency here - or, at least not in any engineering sense. The thermal efficiency I talked about is a function of the engne and the running conditions. It's not something manufacturers can inflate or lie about and it's not dependent on where you live. It's a cold, hard fact and measures the percentage of energy available in the combustion process (ie. in the fuel) that is actually converted to useful mechanical energy. The upper limit of this efficiency (governed by the laws of thermodynamics) is the carnot cycle efficiency - it is not physically possible to get a higher [thermal] efficiency, even in a perfect engine.

      Having had a chance to check some numbers, a typical motor car has a thermal efficiency of about 25%, which can be increased to about 35% in a highly tuned car (carnot efficiency is roughly 60%).

      Contrary to what many people think, the car is actually an extremely well designed system - it has to make a lot of compromises between being reliable, efficient and actually useful (at the most efficient settings, your engine would barely generate enough torque to move the car faster than a pedestrian, for example).

      Then we get into the whole electric vs petro-electric vs hydrogen/electric etc.. Electric hybrids seem best in cities, as you can switch off the big petrol/hydro/fuel cell an idle around on batteries at low speeds, and recharge using regenerative braking..

      Don't get me wrong - I'm all for renewable energy, but these things cost money to set up, especially in terms of infrastructure. Money that Joe Public is not prepared to pay from his/her taxes - and let's be realistic: ultimately this is where the money has to come from. The biggest stumbling block to changing over from petrol/diesel internal combustion to hybrid/electric/fuel cell cars is not really the technology (or even the money-grabbing oil companies) - it's the fact that you have an absolutely massive infrastructure set up all over the world (think petrol stations alone). The cost of changing this over to cater for hybrid is astronomical.

      But if the efficiency v size/weight is good, no reason why the power cell cant be bio.

New York Board of Trade Sugar No. 11 (World) futures for October 2003 delivery stands at 610 cents per pound this morning as I type (NYBOT last day closings also available for future reference). This is raw centrifugal cane sugar based on 96 degrees average polarization. Assume that this is the cost for the raw feedstock for the bacteria.

Dunno what the maximum power dissipation of these batteries are, so I'm making some simplifying assumptions here. Given that electric utility rate above, I pay $0.0720 per kWh, I figure it costs $0.00002 per kW through the electric utility. Another way of looking at this is 564.317 cents per kW works out to 564.317 * 60 minutes * 60 seconds = $20,315.412 per kWh. The batteries won't solve the world's energy needs anytime soon, but the differential in cost might be easily justified with its form factor and other design advantages that it brings to the engineer's table.

    Funny -- I read their story first, mostly to see if I could spot any particular bias or overriding point of view. I will say, the Al Jazeera project clearly identified the Pentagon's connection to the project:

    In a Pentagon-backed project, University of Massachusetts researchers Swades Chaudhuri, an Indian, and Derek Lovley, an American, say the battery's source is an underground bacterium that gobbles up sugar and converts its energy into electricity.

    They didn't go on to show any especial suspicion about that, they just noted it. Later on, at the end of the article, they described the Military applications -- "the US Department of Defence was interested in it for powering underwater microphones and sonar to spot passing ships and submarines." They were quite positive, all told, describing the batteries as remarkable for a proof-of-concept. They mentioned applications in impoverished areas, using batteries working from sewage for example.

    On the other hand, USA Today didn't mention the Pentagon connection, describing the scientists only as being "at the University of Massachusetts-Amherst." The USA Today story was considerably shorter, lacked Al Jazeera's detailed description of how the thing worked ("...each side containing a graphite electrode and separated by a membrane. On one side was R ferriducens swimming in a glucose solution, which it broke down into carbon dioxide (CO2) and electrons. The electrons were transported to the nearby electrode...") and just generally read much more superficially.

    I wouldn't describe the Al Jazeera story as amazingly well-written -- it included some grammatical slips that read as if they'd been made in translation -- but it was a more complete bit of reporting by far, and showed no determined bias other than noting the military connection in a neutral way, IMHO.

    I'd bet the story's submitter included that Al Jazeera link because it's just plain better. Take a look yourself.

    Your point (whether or not the U.S. has directly suppressed with our soldiers the citizenry of an Arab country in support of its dictator) is uninteresting. The original point (that it is difficult to overthrow a dictator that has US support) was not confined to Arab dictators or direct suppression by US forces. However, in the context of the discussion (the relevance of Al-Jazeera) lets narrow the original point to Arab dictorships.

    The United States provides financial, military, and political support to the following Arab governments:
    • Bahrain
    • Djibouti
    • Egypt

    • Kuwait
    • Lebanon

    • Morocco
    • Oman
    • Qatar
    • Saudi Arabia
    • Syria
    • Tunisia
    • United Arab Emirates
    • Yemen.


    The above Arab governments are not lead by democratically elected leaders or are lead by an elected leader who has held office for over 10 years. They are dictatorships, monarchies or other forms of autocracies.

    The US had supported the previous autocratic government of Iraq (I leave Iran out of the discussion as it is not Arab).

    The US military is the strongest military in the world.

    None of the aforementioned countries have seen sucessful popular rebellion once the US began military aid (Several have had forced monarchy successions or military coups).

    Several of the aforementioned countries had successful rebellions before the US began military aid.

    Somalia's Barre lost control of his government despite US support.

    The above points make it reasonable to assert, as in the original point, that it is difficult to overthrow a goverment supported by the country with the world's strongest military as Somalia is the only example of an Arab goverment with US support being overthrown. As a test case, we could withdraw US financial, military, and political support of the Kingdom of Saudi Arabia and watch how long it stands. Your point that no US forces have actively stood against an Arab rebellion (which I agree with) is trivial as long as US resources (including, in rare occassions, direct US military assistance) continue to be used to support Arab dictators and suppress anti-goverment activity.

    You should probably spend more time watch the Daily Show with John Stewart and less time with Saturday Night Live. It will help you drop the (silence), bring it on, LOL and Puhleaze rhetoric that reads like that of an eighth grade drop out.

    A more interesting question than the above B.S. is whether democracy is a worthwhile immeditate goal in the Arab countries. The most stable goverments seem to be the constitutional, parlimentary monarchies of the gulf states (some of which are more liberal than others) but even that stablilty may be wishful thinking. Both Saudi Arabia and Qatar have seen significant internal threats. The democratization of the middle east is probably just so much hooka smoke until the Arabs have had a couple generations of a liberal parlimentary monarchy which may be impossible to achieve while religious freedoms are maintained for fundamentalists. See Turkey for more lessons on balancing humanism (and political freedom) with fundamentalist religion. Perhaps Egypt and Iraq will prove the exceptions, but perhaps not.

There is a bias, definitely -- and it mostly takes the same form we see on something like Fox News in the US: points of view that are closer to the station ideologically get first-person, direct defenses and more time on the air, and the ones the station is less aligned with -- notably Israeli sources -- get less representation and are often described indirectly, at one remove. Anyone who watched Fox describing the protests before and during our recent war will understand exactly what I mean by that. The anchors would go out of their way to frame stories about the protests by saying they were made up of a very few people and so on, and Fox didn't put footage on in which the protestors' point of view was directly expressed by advocates on the air nearly as much as they characterized those views at one remove. (The contempt Fox felt for those protesters was palpable. The anchors practically sneered going into those segments.)

    For all, that, here's an Al Jazeera producer on your bias charge:

    Hafiz al-Mirazi, Al Jazeera's Washington bureau chief, sounds weary when asked about accusations of bias. "The network is much more balanced than it gets credit for," he says. "During this crisis we have been criticized for making Al Jazeera a mouthpiece for the U.S. government. Why? Almost on a daily basis we bring on spokespersons for the administration."

    Al Jazeera did have Colin Powell, Donald Rumsfeld, Condoleezza Rice and Christopher Ross, a former American ambassador to Syria who speaks fluent Arabic, on the air. Tony Blair has appeared too.

    The Norm for Al Jazeera is Arab Nationalism. They're catering to their viewers, of course, but they're doing so at the cost of objectivity. It's more like a circus than a news show. More entertainment than news. Have you ever watched it?

    Absolutely I've seen it. Nationalistic news sources suck, I totally agree with you there. Al Jazeera gets called "The Arab CNN," mostly, when people are trying to describe why it was created and the role it plays. It's struck me as a lot closer to Fox News than CNN, for what it's worth. CNN has always been about direct news feeds with traditional anchors and so on, whereas Fox is much more talk/advocacy driven, and much closer in tone to the last ten years of my US talk radio. Al Jazeera has a lot of really confrontational talk programs on the air, contentious ones, that Fox or MSNBC would be my closest US analog to.

    You're totally right -- looks to be a story cribbed from Space Daily. Gee, I wonder why they didn't spice it up with a bunch of anti-American references and bash the Pentagon angle. Seems like a clear case where they had the chance to, doesn't it?

The tank employs methanogenic bacteria not unlike those found in ruminant mammals such as cows. Its a good, small-scale, low-tech method, but it does require a bit of stewardship to keep the bacteria warm and happy (issues like maintaining the proper carbon-nitrogen ratio can be hard).

    A more recent, higher tech method is to use very high temperature, high pressure water (e.g., 700 C, 100 atmospheres) to completely breakdown and reform all the molecules in a waste stream. This converts just about any stream of organic waste into a mix of CO2, hydrocarbons, and salts. It's great in that it can chew up anything, including plastics and it detoxifies a wide range of nasties like medical waste, dioxin, and pesticides. It's not a small-scale technology, however.

First, many household garbage items might be toxic to the bacteria (e.g., detergents, soaps, solvents, and anti-bacterial cleansers). Second, highly digestive versions of the bacteria could lead to the infamous "gray goo" problem -- a cellulose-eating bateria might take a liking to our houses and trees.
