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
Rust Power
Preface. This is yet another article with an energy generation idea that will probably never work out and become commercial. But it gives hope and dreams to ordinary people who think what a cool idea, and who will never check … Continue reading
