A spacecraft whose bulk consists of magnetic fluid shaped by an internal magnetic field has several advantages over conventional solid metallic craft. 1. It would better be able to absorb high-velocity space debris. 2. It could change shape to the demands of atmospheric viscosity or for the constrution of shuttlecraft. 3. It could more readily withstand internal stresses. 4. Magnetic levitation could be utilized to assist in its flight. 5. A naturally generated radio signal locates it. 6. Its electrical power is generated through external charge flux. 7. Its intial construction would incur less cost than that of conventional spaceships. A magnetic fluid craft might have to bypass strong magneto fields of planets and stars, but these could also be exploited for its efficient propulsion. It may have to be constructed in outer space to avoid large gravitational and inertial forces. Can you foresee any other advantages/disadvantages of magnetic fluid spaceships?
