Military Applications
Buckytubes also have a wide variety of military applications, such as subs. If the hull of the sub was made of nano tubes it would be virtually indestructible. Plus instead of using propellers to push the sub forward, you could charge the hull of the sub with quick short bursts of electricity. This would cause the hull to move back and forth like a shark propelling it forward. Making virtually no noise in the water, as opposed to the conventional sub, which uses propellers and can be heard would make it undetectable. Oil transports would be virtually indestructible making it impossible for them to spill or leak harmful pollutants into the water.
