The United States has Aircraft Carriers that refuel from 20 to 25 years, so isn't it logical that auto makers can duplicate that feat as well? Those wanting electric cars can get them this way. Keep in mind that scientists also made very small nuclear weapons years ago. Called them the Davy Crockett. I do not believe they quit having small nuclear bombs. Those could decide a battle. Remember this is pretty far into the future. Click the MSN link
