In London, Machat wrote the book Gods, Gangsters and Honour.

The first edition of the book was published in the UK by Beautiful Books Limited (UK) in August 2009.

Machat has written a second book about the history of Man through the technique of remote viewing. This book goes back through history and illustrates up to our current time how and why Man constantly gets fooled when we allow others to take care of us. The book is titled the Highways of Man – the Odyssey Almanac (2012). This is a book that sees the history of man for the last 2500 years as a trip down 60 highways that certain men created where each new path was no different then the last; The theme of the book is to illustrate once and for all how Man has consistently allowed third parties to own and control their time here on Earth. Machat”s third published book Man, Community and Living the American Dream (2011) is the conclusion to the Highways of Man. After writing his books and traveling the world, he saw a consistent theme. We are lost as a race and need to get back to our original paradigm of survival as a race of Man, both male and female as equals. Machat shares his views as to who Man the species is all about, answers the questions of every generation of who we are as individuals and as a collective consciousness of Man and offers the paradigm shift of what we must do in for our species to survive.

In 2011, Machat created the Wheel Party using his book Man, Community & Living the American dream as its foundation. The Wheel Party is a non-political people movement whose goal is to bring America back in line with the principles of the United States Declaration of Independence, which Machat claims is the “real mantra of Man.”

Machat lectured across Europe and the United Kingdom at universities, including both Oxford University and Cambridge University, as well as at musical festivals and book fairs.

Steven Machat lost his son Barron, the co-founder of the record label Hippos in Tanks, in a car accident in April 2015.
