Tesla's interest in extraterrestrial signals seems to have begun at the turn of the century when he was working on wireless power transmission at his tower near Pikes Peak in Colorado Springs, Colorado. According to an article he wrote for Collier's Weekly in 1901, Tesla was conducting an experimenting at the site when he began to notice periodic electrical changes:

I am constantly endeavoring to improve and perfect my apparatus, and just as soon as practicable I shall again take up the thread of my investigations at the point where I have been forced to lay it down for a time."
Indeed, Tesla put aside his research into extraterrestrial signals for another few years while he conducted research into wireless power transmission at his new facility, Wardenclyffe Tower, in New Jersey. Eventually though, Tesla's primary investor, J.P. Morgan, pulled his investment at Wardenclyffe when he realized that it wouldn't be feasible to charge for wireless power. This caused Tesla's expensive research at Wardenclyffe to come to a grinding halt by 1907, leaving him penniless and
