I don't think it suggests that at all. It says the Mg is used to make porous silicon out of sand (neat trick), but nothing about how to prevent the porous silicon from reacting with oxygen from the air. So I take it you have to use the porous Si in an oxygen free environment. That shouldn't be too hard to make in a battery though.

That's not only in America. Here in the Netherlands there was a program on TV not long ago about how manufacturers design their products to break down after a few years. There are several ways to do this; the chips in printer cartridges being the most well-known one. But they also told us that Samsung designed the plastics in their washing machines so that they degrade when in contact with the detergent you use to clean your laundry. And many manufacturers build in 'time bombs' in the software of their products, so that they stop working after a certain period.

I agree with all you say. So much so even that I'm beginning to wonder if you meant to reply to me or the person I replied to.
Instinctive fear is of course not in itself irrational, but some people have their instinctive fear tuned up so high, so to speak, that they can't be in the same room with a harmless spider. That is irrational even when it's not yet a fobia.

For large values of one, one equals two, for small values of two.
