Biogas from cow manure is not a solution for the energy crisis

Preface. Smil’s article about biogas sums up why it won’t contribute to energy shortages as fossils decline. Biogass doesn’t scale and is easy to muck up. Hayes (2015) also makes this case, pointing out that even if every ounce of … Continue reading

Why no single or combination of alternative energy resources can replace fossil fuels

Preface. This 2002 paper is still true today. There simply are no renewable replacements for the fossil fuels that power our civilization.  If only scientists could violate the laws of thermodynamics and physics the way capitalistic crooks cheat, like Bernie … Continue reading

Utility scale energy storage doesn’t scale up: limits to minerals and geography

Preface. Natural gas is finite, but aside from (pumped) hydropower, natural 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. And … Continue reading

Not enough rare metals to scale up solar power

  Preface. Sunshine may be free, but the materials to make solar contraptions sure aren’t.  Since sunshine arrives in a diluted form, vast expanses of solar photovoltaic panels will be needed to produce the world’s 24,000 Terawatt hours of electrical … Continue reading

Why rare and valuable metals are not recycled

Preface. This is a post about why rare and critical metals aren’t recycled at all or at best, just a small percent. Basically it is still cheaper to mine them from scratch than to try to separate them out from … Continue reading

What are rare earth metals and how are they used?

Preface.  After oil, the main feature of new products will be drastic simplification. The re-use of existing stuff. Lack of precision machine tools as they rust away. Back to basics: wood, iron, and clay. Yet every high-tech object depends on … Continue reading
