You know what I meant. There’s not another power system as efficient to power large jets, trucks, tractors, combines, etc… than the internal combustion and jet engines. I’m not talking about watches and computers. In most of Europe, the vast expanses of the Great Plains and our large farms and ranches does not exist. We need large equipment to work these farms and pickup trucks and even larger trucks to move millions of cattle and other livestock every day. The large vehicles and equipment we need will NEVER work with battery power. Most Europeans can get by with your small little cars, small vans and little trucks on your tiny streets in your more urbanized society. Most Europeans don’t have experience with our large agricultural industry operations and more rural lifestyle. And please answer how trains can replace air travel? It’s not possible and doesn’t make sense.
