In "SolderSmoke -- Global Adventures in Wireless Electronics" we discuss the way in which Einstein's Special Relativity explains how and why transformers and coils work. I thought it was very cool to be able to see the role of Einstein's theory in our little toroidal transformers. Yesterday The New Scientist (perhaps the best science weekly in the world) brought news that we need to consider relativistic effects if we want to understand how and why our car batteries (and, I suppose, our gel-cells) work:
Thank relativity every time your car starts. Lead-acid batteries get about 80 per cent of their voltage from special relativistic effects.

Yes! It's an amazing meter! I sold mine after getting Telepost's LP-700
station monitor that replaced it. I sold it only because the 100A and the
