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
Carbon capture could require 25% of all global energy
Preface. This is clearly a pipedream. Surely the authors know this, since they say that the energy needed to run direct air capture machines in 2100 is up to 300 exajoules each year. That’s more than half of global energy … Continue reading
How safe are utility-scale energy storage batteries?
