Re: "Polarize the Hull Plating!"
There was a electro-hardening ceramic announced several years ago. While this particular compound is metallic, it seems to work along a similar concept. Should be interesting as this new class of materials come to market. If we can get something as hard as diamond cheaply, there are numerous applications ranging from drilling to manufacturing equipment to artistic etching.
I'm sure the military would be interested especially if allows for a weight saving over traditional armour.
