BASF Shows Off Some Tantalizing Nanotech
Dan B. writes "The Technology section in The Age today is running a story on the current 'Next Generation' nanotech coming to a store near you from BASF. Interesting read, but I'd like some more info on the 10 hour batteries the size of a cigarette lighter."
ok...most of us know all of this already. we all know that nano tech can be a great service...longer battery life, clothes that clean themselves, etc...
what they don't mention are the possible negitive effects. it's like atomic power...great benifit, possibly nasty applications. to apply nano tech to consumer goods is one thing, but to use it to make weapons is quite another (on a morality scale). this technology is more highly adaptive than anything else we have seen before.
governments the world over have been toying with nano tech to make weapons that kill more efficently, are more easily hidden, etc. what happens when common street thugs can "make" their own weapons with nano tech? what happens when countries that have firearms bans (uk, australia, others) have people running arround with nanotech weapons that are small and more leathal than the standard lead slug fired by a gun today? how do you track things like this? what happens when the government/corperation/etc decides to make a nanotech listening device out of the paint in your home?
this is a tech that is to be truly feared and respected. remember...technology is only as good as those who use it.

Recharging them isn't a simple matter of plugging them in the wall as it is now... you've got to replace the hydrogen (or other fuel, most people seem focused on hydrogen for some inane reason, even though it's hard to make and doesn't have much energy content).
;-)
True. "Recharging" a fuel cell will not just involve plugging them into the wall (unless someone makes a *MAJOR* breakthrough in both electrolysis techniques and hydrogen storage).
Most likely, it would work more like a cross between "normal" batteries, and the sort of propane tanks people use for BBQ grills. You would buy a 6-pack of methanol cartridges, roughly the size and shape of an AA battery (as a hypothetical example, of course... I have no more knowledge of future fuel-cell-form-factors than anyone else ). You'd pop them into your electricity-consuming device, just like normal batteries. The actual functional bits of the fuel cell would form a part of the electricity consuming device (or some sort of hip-pack to support legacy devices until everything takes the standard size fuel cell cartridges), and it would simply "drink" from the cartridges you plug in.
When you have a pile of empty cartridges, you'd take them back to the store for a rebate, a lot like recycling an aluminum can. Except, to reuse them, we wouldn't need to melt them down and make a whole new fuel cell, we'd simply refill them. The stores themselves might have some means of doing this, or they might just send them on to some sort of regional refilling center, but the whole process would (could, anyway) involve very little waste.
Of course, I only describe the *SENSIBLE* way to do it. More likely we'd actually build the entire functional fuel cell as a single encapsulated unit, complete with fuel *and* nasty chemistry for the catalyst; ship them across country both ways in a hideously polluting diesel 18-wheeler; and we'd make them out of a plastic that for reasons no one understands, we can't reuse, so they go to the landfill and we waste even *more* petroleum making more plastic.
But hey, what do I know. I need to stop acting so optimistic all the time.
