In the past 15 years I happened to rent in many cities and use all three technologies to heat my food (that is, gas, resistive and induction) and indeed, induction heats in shortest amount of time.
If I was born 20 years before I was born I would be able to enroll in clock-making faculty in University of Technology I graduated. They discontinued this faculty, and the only remaining part was a course of precise mechanics I received..
This article is pure gold. It makes me thinking how much of know-how is already lost and how much can we find in some old book stores... I'd buy a book about clock making.
