Correct. An industry is built on a known or perceived market. If you can’t convince enough people to invest in the new automotive electric battery market, where will you find investors to plunk down bags of gold for an unproven and potentially worthless aviation venture. We know that people can fly via Lilienthal’s gliders and the Wrights’ efforts. Unless you can develop a “virtual” power cord to keep electric propulsion airborne I think better money can be spent developing highspeed rail links between population densities and lower speed rail for smaller communities as most of Europe has done.
