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

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
EV cars only go half as far in freezing weather
Preface. Below freezing, li-ion batteries don’t perform as well. Consumer reports found that about half the driving range was lost. Perhaps this is why nearly half of PHEV/BEV vehicles are sold in balmy California, while the half of the states … Continue reading
Utility scale energy storage has a long way to go to make renewables possible
What follows comes from my book “When Trucks Stop Running: Energy and the Future of Transportation” , which is also where you’ll find the references backing up what I’ve written below. I often get letters from people about energy breakthroughs … Continue reading
Can Zinc batteries save us?
Preface: The New York Times had two articles about zinc air batteries in September 2018. Right now, finite natural gas is the dominant way of balancing unreliable, outright missing, or intermittent power from wind and solar. So other energy storage … Continue reading

Want to go off-grid? You might need hundreds of Tesla batteries
Preface. Although you may not be as far north as Victoria, British Columbia (48.4 latitude), you’d ideally want to be at 30 degrees or less latitude from the equator to even consider the expense of off-grid solar power. And even … Continue reading
Given the laws of physics, can the Tesla Semi really go 500 miles, and what will the price be?
Preface: Most people think that electric truck makers need to tell us the specs — the battery kWh, price, performance, and so on — before we can possibly know anything about their truck. But that’s simply not true. We know … Continue reading
Anyone who whines about airplanes should have to take the Oregon Trail
Source: Book cover of “Oregon Or Bust: True Short Stories from the Descendants of Oregon Trail Pioneers, Prospectors, Trappers, and Settlers in the Great Northwest Hardcover” by Gentry Ward Cutsforth (2012), XLibris. [ In addition, I recommend the Louis CK … Continue reading
