Never need to drink water again

Are you tired of all these different kind of water? You have tried all of them but nothing work. Now there is a new way to intake water without ever taste it. And you don't need to have instrument insert into your body. This revolution product will solve your water problem once for all.

Introducing Rub-on-water, just rub it on your skin and you will never be thirsty again.

Created using nanotechlogy, this ordinary cream is really billions of tiny water collecting robots. Once they are on your skin, the robot will condense water vapor from air and transfer the water directly into your blood stream under your skin. With special collector built-in, the robot will collect and only collect water from air. There will be no worries about chemical or biological contaminant. Nothing but pure water will be available to you anywhere there is water vapor in air.

Order now, we will throw in the amazing nanorobot rejuvenation kit absolutly free. That is right, the amazing nanorobot rejuvenation kit will cause the nanobot to destroy damaged ones and replicate new ones, extend its useful life indefinitely. A $60 value absolutely free.

That must be 35,799,523,000 nanorobots @ .0001676 cents each.

You can already get rub on water, withut all this nanotech stuff. It used as a hand wash, and is like water in gel form.

Nanobots, "special collector" to gather water, "no worries about chemical or biological contaminant": you are a practitioner of magic, Mr Bing.

Explain how these nanobots will get water from the air and purify it, bearing in mind that they're very small, and there may not be much moisture in the air. Or face accusations that the robots will crawl up your nostrils and into your brain.

Difficult charges to deny, as bing obviously has nanobots on the brain...

I suppose that if you were clever enough, you could program and equip the nanobots to build more of themselves from discarded tin cans, etc, so production costs needn't be that expensive.

Perhaps we could change this idea to some kind of surface-tension-based travel-over-water system with lots of tiny rollers attached to a vessel.

If anyone are seriously want to learn about nano atomic construction, I am not the best instructor since I am not so knowledgeable in that area. I admit the idea is crazy because I intend it to be so. But the theory is sound.

At nano scale, you will treat each molecule as individual. Also static electrical force will be the dominate force of interaction between the molecule at this scale. Since all water molecules have the same unique molecular shape and same unique charge, you can design trap door like nano structure that just catch water molecule and repel everything else if you are well knowledged in the molecular interaction at atomic level (No one on earth currently is).

You can argue that there is only so much water in the air that you can extract from no matter how clever the nano designs are. That is true. But you forget the amount water you lost by perspiration at you skin level.

Since I am not defending my crazy ideas, I won't going to crazy details about how the cream will act as second skin, recycle all useful materials and protect people from the element while using minimum energy.

Anyway, I don't do magic because I can find scientific explanation for everything. Relax people, act crazy for a while, it is more fun.

By the way, a nanobot would not be a nanobot unless it can replicate itself. Otherwise it is just a nano structure or nano machine. Do you really expect humoid A.I. machine at atomic level?

Why does a nanobot need to be able to replicate to be classified as a nanobot? I fail to understand your distinctions.
-- bristolz, May 25 2002


There is no fine line seperating machine and robot. Since people tend to classify intelligent machine that act or behave like living things as robot, so self-replicating nanomachines should be called nanobots because they behave like living things.

Here is the interesting part, because all parts of living things act like machines once you divide them small enough. Self-replication and self-regulation are the minimum distinguishable living quality you can use to define something is alive or not at these level.

If you have read Dune, you'll know that people on Arrakis have suits that recycle water from their perspiration, and the suits put the water back into the body. Good idea, but I've seen it in the book. Anyway, who wants nanobots on their bodies? I'll have to throw you a fishbone, for this one.

[MFD] nanobot magic.

but there seems to be quite the discussion here...
-- sninctown, Feb 02 2006


[MFD] don't work, sninc.
But how about....poke thousands of holes in your skin, apply anticoagulant, glue a semi-permeable membrane on top, put a wet sponge on top of that, and voila, osmotic pressure will draw water into your body.
