Some people are just
way ahead of their time. Leonardo drew
plans of helicopters and submarines in 1515; Konstantin Tsiolkovskii wrote of
exploiting asteroid resources in 1904.
Now another visionary, Elon Musk, has proposed a supersonic train
operating inside an evacuated tunnel, serving the San Francisco-Los Angeles
corridor. This technically demanding
scheme seems fated for development many years in the future.
But let us turn to the
November 1909 issue of Scientific
American. (No, not 2009!) In that issue we find an editorial, “The
Limits of Rapid Transit”, based on an essay written in 1904 by an undergraduate
at Worcester Polytechnic Institute and submitted to Scientific American earlier in 1909, advocating the building of a
supersonic rail system serving the Boston-New
York-Philadelphia-Baltimore-Washington corridor. High speeds are achieved by running the
hermetically sealed train inside an evacuated tunnel. Sound familiar? If Musk is a certified visionary for
proposing this concept in 2012, what would we call the lad who advocated the
same idea in 1909?
The precocious lad in
question was none other than Robert Hutchings Goddard, father of American
rocketry, the first in the world to build and fly liquid fuel rockets. He was also the first to discuss putting
astronauts in suspended animation for prolonged space voyages, and the first to
propose the use of gyroscopes to stabilize aircraft—and all of these visionary ideas
originated while he was still an undergraduate.
One
other coda to append to this story: the website “Russia beyond the Headlines”
attributes the origin of the supersonic train idea to one Boris Weinberg of
Tomsk, who published the idea in an article entitled “Motion without Friction”
in 1914. The website reports that Weinberg
carried out tests of his device in which speeds of 6 km per hour were achieved. (Six km per hour is 3.6 miles per hour, the
speed of a brisk walk.) Only in Russia
is 1914 earlier than 1909, and only in Russia is walking speed supersonic. Oh, by the way, in 1914 it wasn’t Russia, and
certainly not the Soviet Union: it was the Russian Empire. For your amusement, the puff piece can be
