Marginal Parasitic Loss Rates

Guest Post by Willis Eschenbach There is a more global restatement of Murphy’s Law which says “Nature always sides with the hidden flaw”. Parasitic losses are an example of that law at work. In any heat engine, either natural or … Continue reading

Argo, Temperature, and OHC

Guest Post by Willis Eschenbach I’ve been thinking about the Argo floats and the data they’ve collected. There are about 4,000 Argo floats in the ocean. Most of the time they are asleep, a thousand metres below the surface. Every … Continue reading
