Does nature use quantum dots?

[8D] Ah but, I happen to be the world's greatest four leaf clover finder. The trick is not to look for them but to feel for them. Though I did try to find one on a hill which locals believed was occupied by the Sidhe (pr: sthee, or shee) I couldn't find one.

Armed with a four leaf clover from such a place, it's possible to see these people. They run the planet but let us wander about the surface to deter alien visitors[8D]

Getting back to models Jim, I can see that you don't like them but i can't see what you want to replace them with. I think that most people are a little cavalier with the use of the word but a model can be something that is real but doesn't exist. The number plain is an example. A is B, the moon is made of emanthal cheese, all models.

As for cracking water, we can but the cost is ridiculous. This subject is one beloved by garage experimentors, and it has to be said that they do get some hydrogen out. What they don't allow for is how much mains electricity they use to get it.

Here we have a a protonic current which depends on a rotation. The rotation has to take place around three of the surface hydrogen "protons" in the hexagon shape of ice. Rotate these 360 degees and it's back to being the configuration of ice again. However, the rotation needs an electron current to move one space over to rotate the other three water molecules in the hexagon. The whole shooting match wil continue to rotate past the 180 degree mark, where it doesn't have the ice configuration at all.

At this point the whole structure has dragged itself over diagonally so that all of the bonds are stretched and the water molecule is over the "hole" in the hexagon of magnesium. Now thi has to be where the hydrogen is snipped off. Further, an atom of magnesium can be mad to look like neon, so that it can release its captured hydrogen atom.

Another model I'm afraid [8D][] It's a kind of super duper gattling gun[] I think it's small wonder that we haven't been able to do it yet. Get the timings wrong and the guns jams on us. The good news is, that I can't believe that early life sat about with slide rules working this all out beforehand.

The cost of transforming water into hydrogen and oxygen depends on how its done. Plants do it for free. Humans do it at a cost that is not all that out of line with other things people do. There is a project in Norway that uses windmills to do this and it works well for them. It is a matter of how rather than if it can be done at a cost that makes sense.

If we want to crack water we ned to heat it to 2000 degrees C. Plants do it using low temperatures and the energy of visible light. If we could do the same trick, then we wouldn't need to worry about our energy needs for a very long time. Further, it would be environmentally clean and not subject to mining problems in politically unstable regions.

Sloat, You are correct in your last post and it can be done with current state of art devices. The simple fact is that solar energy should and could be used to make hydrogen from water right now. It is a very efficient process and would reduce polution,incease the total available energy and make energy a lot cheaper than it is. No one is thinking about this at this time because models are in vogue that indicate the sky is falling a lot faster now than in the past so we have to stop.
