Rex Research posted a fantastic report recently that I was really pleased to discover called "Suppressed & Incredible Inventions" by John Freeman from Health Research in 1987:
@deandddd you're going to love this book. I can't help but think that Joseph Cater also must have read this book due to a number of inventions he reiterated from this. This is a fantastic survey of inventions from the past century that really could have made all of our lives so much better and in so many ways.
Also @deandddd did you say you were familiar with the publisher Health Research and Al Fry?
