mattnyc99 writes "There was plenty of chatter last week about an MIT announcement that researcher Angela Belcher had developed a way to create virus-based nanoscale batteries to power mini gadgets of the future. In a fascinating followup at Popular Mechanics, Belcher now says that her unpublished work includes full-scale models of the batteries themselves, and that they could power everything from cars and laptops to medical devices and wearable armor. Quoting: 'We haven't ruled out cars. That's a lot of amplification. But right now the thing is trying to make the best material possible, and if we get a really great material, then we have to think about how do you scale it.'"

So they made some viruses that are supposed to make little wires. Then they used the viruses to make some little wires. Then they wrote a paper. Then they worked on some more viruses to make some other wires that could be used as the other necessary component of a battery. And they're writing another paper.
That really sounds like pretty much how it's supposed to happen.

Creating 1:1 scale battery models is one of my hobbies. I find that tubes from toilet paper rolls work well as a base for models of D cells. Large drinking straws are a good starting point for AAA cells. Old laundry detergent boxes are great when you want to move to more advanced projects like automobile batteries.

Not models. Prototypes. There's a difference. (Score:5, Insightful)
"A much-buzzed-about paper published in the Proceedings of the National Academy of Sciences earlier this month details the team's success in creating two of the three parts of a working battery--the positively charged anode and the electrolyte. But team leader Angela Belcher told PM Wednesday that the team has been seriously working on cathode technology for the past year, creating several complete prototypes. "
"The cathode material has been a little more difficult, but we have several different candidates, and we have made full, working batteries."
They've actually built things, that work, though the 3rd component the cathode is still apparently a work in progress. The summary says "models", which of course means something specific to /.ers, but that isn't the reality reflected in the articles.

"Prototypes" mean something specific to us too.. and it isn't "2 out of 3 critical components, not even integrated yet".
Actually, it can, because they can be prototypes of the components. Two of which have been integrated. And they've made full, working batteries, just not using their cathode technology yet.

I see nothing in those articles about these batteries being "mega efficient", as the title of this Slashdot post screams. The novelty seems to be the fact that they're grown using viruses and can be applied in thin films.
Oh, no, that is not complete story of what this bugs could do. Think about it for a moment:
1. those are big-molecule-sized particle batteries.
2. You can construct them in such a matter that their terminals can be accessed only trough specific shape of (molecular, e.g. an enzyme) connectors.
3. You can make each terminal incompatible with opposite polarity terminal, allowing for suspending those batteries in a liquid, or, if the batteries can bond with each other through (weak) hydrogen bonds, a large mass of them might already be in liquid form.
Now, what is that all together? An "electric fuel", something that might power electric cars, but refuel on pump stations in same time ICE cars refuel. Car would have nanobatteries' processing unit, which would allow parallel connection of great many such batteries, pumped from the "fresh" tank. Once discharged in processor, batteries would be would be pumped into "used" tank.
Bonus points for hypothetical clever battery design that would spoil terminals' shape if battery is empty as it would allow processor to be installed in "fresh" tank and just keep the tank stirred enough. Once processor squeezes out all the "juice", battery should fall off it, allowing connection with another, fresh battery to commence.

You make an interesting point about Bacteria infecting things ; Maybe an offshoot of this research could be a medical-process for removing heavy metals from the human body. A method of completely counteracting Lead or Mercury poisoning. I wants to eats Salmon all the time darnit! I just don't want the brain tumours that go with it.
I imagine though, that would involve creating a much more sophisticated virus that itself attracts the metals, rather than using the bacteria they've already created. Unless you could get it up your nose and leave it there so you can blow mercury snot out of your nose. That would be kind of cool, in a 'My snots toxic' kind of way.

And you most certainly could RIGHT NOW. You would just have to scale back your standard of living to the time when humans were doing all the work. Back to a family of 4 in a 1000sq.ft. home, with no AC and a max of one car per family. Going to see a movie would be an event. Most people prefer their McMansion with constant entertainment.

The advantages aren't clear (Score:4, Insightful)
It's obvious that weaving these batteries into fibre (for example) or just the fact that they can create such tiny batteries is hugely advantageous from an engineering perspective. Now clothes can be powered, etc.
What isn't clear is why would you want these batteries to power your car? I don't really see any discussion on whether these pack more power than a 50lb car battery would. From the description it sounds like they're just regular batteries which expire, but are tiny. So by my no-math-involved logic, 50lbs of these nano-batteries should pack about the same punch as a regular 50lb car battery.
Am I wrong about this? Do the infected bacteria constantly replenish the components of the battery making them more like a generator that runs on raw materials ? Because it doesn't look like that, it looks like they create the components, stop the process and put them together.
Very very cool, but it sounds like the same technology we've always had is the end product. Please tell me I'm wrong, I want this to be the mini nuclear generator powering our cars we were all promised in the 1950's.

Can't Reproduce? (Score:3, Insightful)
How is the fact that they can only infect bacteria relevant? I have plenty of essential bacteria that I consider more or less my organs. That is not any better than saying it can only infect kidney cells.
If they cannot reproduce (even after infecting a bacterium) it shouldn't matter, as there should not be a sufficient amount of these to stop anything.
However, if these things are being mass produced, it seems to me the odds are that pretty soon at least one virus will show up that can reproduce itself. The question is: how many mistakes in transcribing the virus' genome in the lab would be required to allow it to reproduce?
Copying errors are the heart of evolution, and they will happen even on the production line.

"
The M13 viruses used by the team can't reproduce by themselves and are only capable of infecting bacteria. At just 880 nanometers long--500 times smaller than a grain of salt--the bugs allow researchers to work at room temperatures and pressures with molecular precision, using and wasting fewer hazardous materials in the process. Now that they've demonstrated the construction of such tiny electronic components is possible, the challenge facing researchers is how to make them practical."
As in the virus "inside part" is actually done. They've also got the anode construction done. They're working on the cathode.
This is a practical engineering project at this point. This is news. Who knows if it will end up "practical", but nevertheless it is real whether you rtfa or not.
