Yes, but the heat was generated by folk who didn't understand how it could work; no-one claimed it was a new idea.

I wonder how many other good ideas are lying  forgotten and gathering dust in patent offices around the world.

I remember back in the 70's or early 80's a company came out with a gapless automotive piston ring.  When they tried to patent it, turns out it was already patented in the 50's.  The 1850's!  For use in steam engines, of course.

In recent years(?) Martin Cleeve toolk out a provisional patent for a swing tool.

Blackgates and Hemingway both have or had kits for it.

It's also repeated in ME and EIM
