Biocoal from food waste and sewage
Preface. This probably doesn’t have a net energy gain because of the energy to move waste and sewage to a common facility, and then transport these wastes from numerous places to the factory where biomass is converted to coal using … Continue reading
How will 500,000 products made with fossils as feedstock & process energy be created post fossil fuels?
Preface. It is quite likely that after fossils are gone, plastics will no longer be made, since they are incredibly complex – PhDs in numerous fields make them possible – and most kinds have been around for only 50 years … Continue reading

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

Far Out power #6: Stale beer, crayfish shells, and burning metal powder
Preface. Unfortunately, turning beer into biogas requires a pandemic so that it isn’t drunk at pubs instead. Scientists assure us there will be more pandemics as we mow down (rain)forests for shopping malls and come into contact with new viruses, … Continue reading

800 scientists: Burning forests for electricity & heat releases more 1.5x more CO2 than coal, 3x more than natural gas
Preface. The 2015 Paris climate change agreement states that burning biomass is carbon neutral. Not true. Over 800 scientists have written the European Parliament to tell them that burning wood for heat or electricity emits 1.5 x more CO2 than … Continue reading

Reforestation can cause rivers to disappear
Preface. We’ll need a lot of forests in the future when wood once again becomes our may source of energy and infrastructure as it was before fossil fuels. But care needs to be taken on where trees are planted. Alice … Continue reading
