Magnetohydrodynamic drive In concept‚ MHD is attractive because it offers a propulsion system that requires no moving parts. It works on a principle similar to that of an electric motor or generator; that is‚ passing an electrical current through a magnetic field creates a force. In an MHD propulsion system‚ a magnetic field is created within the hull‚ and sea water is used to conduct the electric current‚ as shown in the illustrations accompanying this story. The underlying principle is known

Hard Drives Hard drives have been around longer than you think. In 1956‚ I. B. M. had invented a disk storage unit that was very large but did not store a lot of data. It was twenty-four inches in diameter and could hold only five megabytes‚ which is the equivalent to three and one half floppy disks. Originally called “fixed disks” later became known as “hard disks” opposed to floppy disks. In 1973‚ I. B. M. released a hard drive that could hold seventeen and one half megabytes. In 1980 Seagate
