Morphing Metals

aarondubrow writes "Imagine a metal that 'remembers' its original, cold-forged shape, and can return to that shape when exposed to heat or a magnetic pulse. Like magic out of a Harry Potter novel, such a metal could contract on command, or swing back and forth like a pendulum. Believe it or not, such metals already exist. First discovered in 1931, they belong to a class of materials called 'shape memory alloys (SMA),' whose unique atomic make-up allows them to return to their initial form, or alternate between forms through a phase change."

    Imagine a carriage that propels itself without the need for horses, fuelled by otherwise useless petroleum spirits. Like magic from some Jules Verne novel, such a carriage could carry a family for hundreds of miles at high speed without tiring, and could revolutionise transportation. Belive it or not, such carriages already exist....

      Those are the work of the devil. They will stop chickens from laying eggs and the speed that people will move in them will suck the air out of their lungs.

    I didn't know that the Terminator movies were written by this Harry Potter person.

    The terminator movies weren't written. They just put the robots on a stage and let them improvise.

    What! It works with Keanu Reeves.

    Imagine a car made out of this kind of metal. Someone ploughs into you, tow the car home, apply a flame and presto! off you go again.

    Having seen several Keanu films... no it doesn't

    He was fine in a little movie called "The Matrix". Shame they never made a sequel.
