Generating electricity with biomass at utility-scale in California limited to direct combustion in small 50 MW plants
Preface. It’s obviously much easier and more energy efficient to set logs on fire for heat and electricity than to turn them into ethanol. Burning biomass can’t do much to solve our energy crisis. To produce just 10% of … Continue reading
Steam powered farm tractors
Preface. Steam engines weren’t very efficient, 10 to 20% at best, which is why they went away beginning around 1920 when oil-powered engines came along. At the very best steam engines for transportation reached 10 to 20% efficiency. They were … Continue reading

Foreign Policy: The limits of clean energy
Preface. This article appeared in the magazine Foreign Policy. Some key points: Renewables to power the world would require 34 million metric tons of copper, 40 million tons of lead, 50 million tons of zinc, 162 million tons of aluminum, … Continue reading
Airplanes are energy gluttons. Finite oil should be used for ships, locomotives, & trucks
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
