We have to invent a process, a chemical extraction process that will make the production of magnesium cheaper so that we will have the opportunity to avail ourselves of energy-efficient materials.

But, we know for example that magnesium, when it reacts, it reacts with both of its electrons, not just one of its electrons.

So, I went to the library and I looked up Advances in Molten Salt Chemistry volume six because there's an article in there about the chemistry and electrochemistry of magnesium production.

But a magnesium atom would carry two electrons, so a battery storing a given amount of energy could be nearly halved in size and weight.

But there may be an alternative: magnesium.
