Utility scale energy storage batteries: only enough material exists on earth for Sodium sulfur (NaS)

[ Natural gas is finite, but aside from hydropower, gas is the main way wind and solar are balanced now. Therefore, a tremendous amount of energy storage will be needed in the future as natural gas declines, hydropower (remains stagnant … Continue reading

Hybrid electric trucks are very different from HEV cars

[ This document explains why it is hard to transfer auto hybrid technology to trucks.  They are entirely different animals — medium-duty trucks weigh up to 10 times more, have up to 10 times the horsepower, and a far longer … Continue reading

Who Killed the Electric Car?

[ Who cares about electric CARS?  Civilization ends when trucks stop running, and trucks can’t run on batteries because they’re too heavy (93% of the cargo weight, 25% of the cargo space), and an all-electric truck fleet would require thousands … Continue reading

Would Tesla, li-ion batteries, SolarCity or SpaceX exist without $4.9 billion in government subsidies?

[ Tesla made no new battery breakthroughs — batteries aren’t much better today than they were 200 years ago.  All they did was build a better battery management system (BMS) by stringing teeny-tiny batteries together — thousands of them, and … Continue reading

Making the most energy dense battery from the palette of the periodic table

There hasn’t been much progress in batteries the past 200 years, not enough for affordable cars, let alone far more essential freight vehicles. The very heavy, 4,647 pound Tesla Model S gets most of its mileage from aerodynamics, reduced rolling … Continue reading

All Electric Trucks. Probably not going to happen. Ever. Why not?

There are “forms of transport that cannot be electrified — heavy-duty trucks and planes… Even if the electricity problem can be solved, it won’t address the needs of planes, trucks, ships and some industrial heating that cannot be electrified” (Long). … Continue reading
