Faster than This Speeding Train, Superman?

On December 2, 2003, a magnetically levitated train developed by the Central Japan Railway Company set a world speed record of 581 km/h (361 mi/h). The train is planned to run a normal 500 km route between Tokyo and Osaka in one hour. Liquid-helium-cooled superconducting electromagnets are sequentially repelled and attracted by conductive coils in the track's sidewalls for propulsion. To minimize friction, the entire train is magnetically levitated above and between the rails. For comparison, the famed American P-40 Warhawk and British Spitfire of WWII had about the same top speed in level flight.

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a lady's voice announced "You've Got Mail" when a new message arrived...
