Joe, you shouldn’t be surprised. The overwhelming majority of comments on this site are negative comments from anti-progress arm-chair quarterbacks who think they know more than the engineers and experts who are actually working on projects. They also fail to recognize signs of technological disruption. These are the same type of folks who said that the horse-less carriage would never work and that the internet was a fad.
The technology will progress, battery capacity will improve with breakthroughs in Li-Sulfer and Li-CO2 (and perhaps other chemistries we have yet to hear from) and electric aviation will happen in some form within the next 10 to 20 years because the industry really wants it to work. Most of these folks are against electric cars, yet GM announced that by 2035 all of their models will be electric, so these folks will become irrelevant as they maintain their denial of climate science and their short-sighted love of internal combustion engines that are not only bad for the environment, but are also expensive and inefficient to operate.
So Joe, don’t let these dinosaurs get you down. They can bloviate all they want while others are paving the way to the future. They will eventually be forgotten as technology brings us new things to get excited about.
