In the spring of 1991, I began contemplating ways to combine the benefits of gas turbine power plants with the incredible advantages of nuclear fuels like uranium, plutonium and thorium.

That effort has continued sporadically for many years with many interesting impacts on my life. It was impetus for a small modular reactor start-up company that never gained sufficient traction. It has led to many fascinating conversations and more than a few close friendships.

I thought it would be worthwhile to share an updated version of a concept paper first published on the Adams Atomic Engines, Inc. web site in 1995.
