There are 454g in a pound, so one pound of Gallium costs $1362.

I don't know what the ratio of Al/Ga would be in this magic alloy, but assuming it's 10:1 in favour of Al - somewhat conservative - you're looking at a tank that costs $47,670 to make if there are 350 pounds of Al.

If it's 1:1 it's more like half a million.

Even at 100:1 you still have a tank that costs nearly $5,000.

This would make cars very, very valuable commodities - possibly even more so than they are now.

The press release doesn't specify the amount of gallium needed.

Maybe someone should call them and ask?
