Thanks for reporting on this, Elizabeth. It's especially interesting to read about developments in making better li-ion batteries--which I think still hold promise--in the middle of Boeing's woes.

Napelou, I also wonder a bit about the "unintended consequences" that could result.  A similar problem exists with those imported fish that got into the Mississippi river a few years back and are now threatening to decimate the existing fih in the great lakes. Somebody starts something with out considering the potential for damages, and with no precautions taken, one small error and the damage is done, and in some cases the damage is irreparable and quite extreme. And now, in the case of the fish, our stupid government officials are dragging their feet about taking any real steps to prevent additional damage.

In the case of power generating bacteria it would certainly be handy to know how to destroy it quickly if ever there was a spill, and we can be certain that there will be a spill if the technology does work as well as anticipated.

Hi, AnandY, the bacteria used in the experiment, or at least one of them, was shewanella oneidensis. I don't know enough about it to know if it is the type that can make its own food or how it feeds...perhaps you do?

I am not familiar with those, William K, but I wouldn't be surprised if that research was a precursor to this. It seems like a lot of these ideas are borrowed or have evolved from similar ones from previous generations. Agreed that if they could really make the organic formula user-friendly, then this could definitely be a winner.

I think that's a valid concern, naperlou, but I'm sure the designers of the battery and the scientists doing the research would hopefully have a way to prevent such a thing from happening! Could make the plot of a good scifi film, though!

Are these batteries anything like the "biocell" batteries that we heard about back in the 1970's? I know that there is some valid means to recover electrical energyu from the biological digestion process but I have no idea how similar the different processes may be, or not. But it does seem that some sort of organicly fueled battery could be useful, unless it uses a custom fuel type that is expensive. But a generation mechanism that could be powered by dead leaves and grass clippings would be a real prize winner.

It would be interesting if you could recharge the cells by simply adding food to the cells.


@Recharge, some of the bacterias can make their own food from sunlight, just like plants. Some of these bacteria can live off unusual "foods" such as iron or sulfur. So it would be interesting to see what kind of bacteria is being used for this experiement.

I also wonder if you could vary teh amount of electricity generated by the kind of food fed to them.

@Gorski, I think it would be too early to predict the effect of food being fed on the amount of electricity generated by them. But I think we can vary the amount of electricity generated by using different minerals and metals.

@Elizabeth, thanks for the post. Its fascinating to know that electrical current can be generated by touching proteins on the surface of bacteria to a mineral surface. What kind of metal or mineral was used for this experiment ?

More often than not, with the purchase of a sports car comes the sacrifice of any sort of utility. In other words, you can forget about a large trunk, extra seats for the kids, and more importantly driving in snowy (or inclement) weather. But what if there was a vehicle that offered the best of both worlds; great handling and practicality?

Science fiction author Isaac Asimov may have the best rules for effective brainstorming and creativity. His never-before-published essay, "On Creativity," recently made it to the Web pages of MIT Technology Review.
Much has been made over the potentially dangerous flammability of lithium-ion batteries after major companies like Boeing, Sony, and Tesla have grappled with well-publicized battery fires. Researchers at Stanford University may have come up with a solution to this problem with a smart sensor for lithium-ion batteries that provides a warning if the battery is about to overheat or catch fire.
