However it is viable on the <B>Moon</B>, simply run some steel or aluminium rails around the inside of a medium sized crater. Lunar escape velocity is 2.38 km/s. Speed of sound is 6.1 km/s in steel and 4.877 km/s in aluminium.<BR/><BR/>A Maglev may still be viable on Mars, escape velocity is 5.03 km/s if steel rails are used.<BR/><BR/>The Maglevs can be solar or nuclear powered.Andrew Swallowhttps://www.blogger.com/profile/10945854011042065256noreply@blogger.com
