But since you don't have a patent on that, but you could, your next bet is to hit up all the HFT firms, international finance, etc. I'll take 5% for the nudge ;) _------------------------------- Jim Bell's comment: In the movie, they were beat by exactly that: microwave towers. Ordinary quartz fibers have an index of refraction of about 1.42 at 1550 nanometer wavelength. My isotope-modified fibers should have an index of refraction 5.6% smaller, so the signal should go 5.6% faster. However, Starlink's system may beat both these systems, as it is low-earth-orbit. The 'horizon' of a satellite with an altitude of about 1 million feet (200 miles) is about 1230 miles. So, it is conceivable that such a satellite could be (temporarily) positioned between Kansas City and New York City to allow faster connection. Alternatively, if Starlink's satellites had satellire-to-satellite communication, such connections might be more regular and not discontinuous.
