EV's and weight
Most articles about EV’s, recognize that the power source must be green, or the whole purpose of the car is lost and they lead off with how the cost of solar panels have come down over the past 20 years and this is a fact. What they don’t write about is the materials needed to produce EV’s which include lithium, nickel, cobalt, manganese, graphite and copper along with rare earths neodymium, praseodymium, dysprosium and terbium. These are left out because of the environmental harm caused by the mining, processing and disposal of these elements. The second area left out is how airplanes and heavy equipment will operate on batteries. Both military and commercial planes are jets and ocean liners, tanks, bull dozers and large farm equipment need more power than batteries can supply. A Tesla long range semi-truck weighs 23,000 pounds including the 11,000-pound battery. An Abrams tank weighs 128,000 pounds and would require a 61,000-pound battery. When out on the battle field where would the charging station be. A diesel locomotive weighs 450,000 pounds and would need a 215,000-pound battery. When it comes to ocean liners and oil tankers the numbers are out of sight. Overwhelmed by the excitement of EV’s many of these problems are ignored. The problem of building EV’s before charging stations are installed and these cannot be supported without updating the grid is just putting the cart before the horse.
