MIT Building Batteries Using Viruses 98

Posted by ScuttleMonkey
from the i've-caught-a-battery dept.
thefickler writes "Researchers at the Massachusetts Institute of Technology are now using viruses to build cathodes for Lithium-Ion batteries. Three years ago these same researchers found they could build an anode using viruses. Creating both the anode and cathode using viruses will make batteries easy to build. This nanoscale battery technology will allow batteries to be lightweight and to 'take the shape of their container' rather than creating containers for the batteries, which could open up new possibilities for car and electronics manufacturers."

      Right, really infectious power. The mutations might cause a new cold fusion discovery real soon now.

      But then again, it is kinda neat to get those little bastards doing some handy work for us. However, I am a bit sceptical whether it would be efficient on an industrial scale, like so many other innovations.

      (Doctor pulls out voltmeter.) Hold these, please. Yep, you're infected.

    • The synthesis takes place at and below room temperature...

      Specifically, they manipulated the genes in a laboratory strain of a common virus, making the microbes collect exotic materials -- cobalt oxide and gold...

      Indeed, I hope they are careful with these viruses, because if they got infected, and happened to be suffering from hypothermia, the viruses could use up their bodily gold and cobalt oxide, and then they could get shocked! Assuming they had AIDS too that is.

      Well, yes, the people who use that tag are all reactionary luddites, and this story will appeal to them.

      Please, what could go wrong with this? The virus escapes and... err... behaves almost exactly like the virus it was engineered from? Except, you know, in presence of iron phosphate (a rather rare substance) it grows in a different shape. Clearly a danger to the survival of our species, there.

        First of all, it has already been pointed out you used the wrong word "there" instead of "their" which is just brilliant irony.

        Secondly both words "virii" and "viruses" have been used widely. Quoting a single source (poorly without previewing) to single one out as the "correct" one is just silly. At the very least if you're going to point out the mistake, point to some relevant information on why "viruses" is the correct pluralisation. Here I'll do it for you: http://en.wikipedia.org/wiki/Plural_of_virus#Use_of_the_form_virii [wikipedia.org]

        Thirdly, why do you quote the rest of the definition of the word virus? I didn't realise this was some obscure and unknown word that needed to be explained.

        In summary, pipe down you arrogant jackass. Correct your own mistakes before trolling over other people's.

Furthermore, both use morphological pluralization rules found in other words in the language (for example, /cacti/ and /foxes/. From a linguistic standpoint, it doesn't really matt

      without that bacteria, you would:
      - get infected with every crap bacteria you touch (your whole skin is coated in good bacteria, to keep the bad away)
      - not be able to digest your food (your intestines are full of them, doing good work for you)
      - and even change your way of thinking (because bacteria interact with the communication of neurons. complicated stuff. can't find the article now.)

    Wonderful ! Now, instead of having some standard battery sizes (AA, AAA and so on), we are going tu have as many different shapes of batteries as there are products, not only between manufacturers but within the line of the same manufacturer (for the same reason that Gillette has 10 different shapes of blades, or than portables PCs have 200+ type of batteries, or that we hare 20 or so different AC/DC transformers at home), so you will have to buy every time a given manufacturer's battery and throw it away rather than reuse it on a later apparatus.
