Untimely inventions – products before their time (1)

There are many examples of inventions that were way ahead of their time. So much so that some would not come into use for another thousand years and some would only come into general use almost 100 years after they were designed.
The first fax process was patented in 1843 by Alexander Bain, but fax machines went into service only in 1964. In 1888, Frank Sprague completed an electric railway, but electric locomotives were introduced only in 1895. Eugene Ely landed a plane on a boat in 1911, but aircraft carriers weren’t perfected for another 20 years.
