Russian post war advances and engineering culture came at the hands of captured German scientists. The cold war provided an external 'threat' that compelled the tyrannical USSR to permit innovation in military arms. That and the extensive spy network of the KGB that stole US, British, and other allied designs.
The Chinese were good customers of the Russians until they decided that they could go into business for themselves. They started building knock-off Russian jets much to the behest of their 'friends'. I guess there is a case to be made for Karma.
I never said American engineers are superior. But the fact is, for various reasons, since WWII we have excelled to the head of the class. There is no guarantee that we will remain the leaders, particularly with this administration in office.But free market systems and free people will always lead the repressed.Marxist and tyrannical nations will always be inferior - as proven by the 20th century.
Few new EVs are using lead acid batteries, but they can be fitted with reformers to capture vented hydrogen and oxygen. The mass flow in a lead acid cell is almost nil compared to an ICE. Just compare the exhaust pipe on a typical car to the vents on a battery.
Both the ICE and battery use the air for cooling. But the battery will typically produce much less heat for the same output.
The old Soviet Union cranked out better tanks than the Nazis in World War 2, their Kalishnikovs were more reliable than either the Allies or the Nazis equipment. Their aerodynamists are among the best in the world and their computer scientists and engineers are well respected generally. Again if the commenter was not so Americentric statements like the above would not be made...the communist regime took a feudal autocracy from wooden plows and made it into a modern industrial nation and fought a successful war against the Nazis with little help from its Western allies....no amount of American propaganda is going to deny these historical facts
Oh come on now! The Chinese do not need to reverse engineer anything any more than Americans. The idea that success can only stem from the US is nonsense...the British helicopter BERP rotors is proof of that! Curiously enough there is very little reporting in this magazine on what the Brits are doing(or for that matter the Europeans) where EV's are concerned. In this age of globalization one would expect less Americentric smugness...the real problem with EV's is that scaling up to autos was too big a jump....E-Scooters work just fine because at that scale and weight, the batteries can manage using simple controllers.
The Smart Emergency Response System capitalizes on the latest advancements in cyber-physical systems to connect autonomous aircraft and ground vehicles, rescue dogs, robots, and a high-performance computing mission control center into a realistic vision.
