New e-book just published by Robert Green

"Steam Age Machines" contains descriptions and 100 fine etchings and drawings of late 1800's industrial machines and steam engines. The beautifully detailed etchings are of framing quality and show the highest point of the technology. The pre-OSHA machines reveal the innermost workings of the gears, flywheels and structure before safety regulations hide them from view. This book also gives a brief history of the steam age and the contribution and legacy that is still in use today. In the last chapter it lays out the possible future of technology and its relevance for future generations of steam power systems.
