97% of vehicles and trains run on oil which peaked in world-wide production in 2005 — the tractors to plant and harvest, the trucks to deliver food all depend on combustion engines that burn oil

EV cars and utility scale energy storage batteries are not likely to materialize

Preface.  Clearly there’s not enough minerals and metals to shift from fossil fuels to electric vehicles and utility scale battery storage, due to peak critical elements, peak platinum group elements, peak precious elements, peak rare earth elements, and peak everything … Continue reading

Heavy-duty hydrogen fuel cell trucks a waste of energy and money

Preface.  Hydrogen fuel cell trucks are incredibly inefficient. Turning hydrogen back into electricity with a fuel cell is only 24.7 % efficient (.84 * .67 * .54 * .84 * .97) as shown in figure 1. There are multiple stages … Continue reading

A billion new autos by 2030 will kill climate change

Preface. The article below argues that electric cars aren’t going to replace gas and diesel vehicles enough to lessen greenhouse emissions. The average electric vehicle requires 30 kilowatt-hours to travel 100 miles — the same amount of electricity an average … Continue reading

Super heavy trucks ruin roads

Preface. I’m writing a book now which concludes that only biomass and biofuels can replace diesel and other fossil fuels.  But 3 billion people are expected to arrive by 2050, consuming a good chunk of the biomass, plus it will … Continue reading

Nuclear powered airplanes, cars, and tanks

Preface. After all the research I’ve done on rebuildable, not renewable wind and solar, hydrogen, batteries, and other Green dreams of an endless future of growth based on them, I’ve come to see them as just as likely as nuclear … Continue reading

Life before Cars: When Pedestrians Ruled the Streets

Preface.  The past is future after fossil fuels, but minus the horses for a while, since before cars they required about a sixth of U.S. farmland for their feed.  My grandfather, Francis J. Pettijohn, used to fondly reminisce about how … Continue reading

MIT: Why the electric-car revolution may take a lot longer than expected

Preface. This study from MIT explains why price parity of electric and gasoline vehicles is likely to take a lot longer than 5 years, and perhaps never if cars continue to depend on lithium-ion batteries. Deeper cost declines beyond 2030 … Continue reading

Why self-driving cars may not be in your future

Preface. Below are excerpts from several articles about why a completely automated vehicle is unlikely.  Heaven forbid they are invented. Researchers have found that people will drive 76% more miles, stop using bicycles and mass transit, waste a considerable amount … Continue reading

Airplanes are energy gluttons. Finite oil should be used for ships, trains, and trucks instead.

Preface. As oil declines and the energy crisis worsens, airplanes ought to be the first to go since they are 600 times less energy efficient than large cargo ships (30,000 / 50), 50 to 120 times less efficient than trains, … Continue reading

Tesla pickup truck claims defy the laws of physics by John Engle

In 2017 scientists questioned whether the Tesla Semi could meet Musk’s claims (see post “Given the laws of physics, can the Tesla Semi really go 500 miles, and what will the price be?”). I suspect this is why Tesla has … Continue reading
