Selling an idea anywhere is possible if the idea is credible.   If the idea is based on fact and research, has a use that will be sustained by consumer, industrial or scientific demand, and can be applied with a reasonable amount of cost and production time, it will be worthy of being sold.  If the idea is a theory, it must have merit and be based on experimentation, that has been tested and found to be true.  If the idea came from sound reason, and does have credibility; and the person who had the idea, believes in its value; then that person will communicate with those who would benefit from the information, and convince them to apply it, in whatever form is appropriate.  Location does not matter, if an idea has merit, it will find its way into the real world.
