> the core is 4000-6000 Deg C
This might be a bit of a side track but here goes anyways...
The currently accepted explanation for this temperature is "decay of radioactive elements within the mantle".
But I suspect that something else is going on. How so?
>The Earth's core radiates somewhere around 47TW into space
Is there really that much radioactive decay going on? Has anyone ever done any calculations to see how much decay of whatever elements would be needed to produce that much energy? Can the process of radioactive decay produce that high a temperature (roughly equal to the surface temp of the Sun)?

This is such a Quasie idea, it just might work!

>they have changed for the shorter attention spans
Also possible/probably influence from the advertising industry. How so?
They did their research and found that (in a 30s ad) shorter cuts hold the viewer's attention more effectively.
I'm sure some people in Hollwywood took notice of this, adapted the principle for their own work... and it succeeded.
And then got widely copied. And here we are today?

1 year ago this would have been scifi. Now it's something James Cameron is using for his movie.

I'll take anything that can be put into mass production and get us off our fossil fuel dependency.

SS: Yeah I know, another battery article. However...
The breakthrough here is in the use of magnesium as an anode material.
Putative benefits are:
-
Comparative abundance of Mg (vs lithium)
-
A high theoretical capacity and negative electrochemical potential.
-
Inexpensive material.
