Miley elaborates the case for advanced fuel fusion energy well in this profound book. His fusion research has been directed towards low neutron emission nuclear energy production, corresponding to the dream of a "golden age" where the ten million times more efficient nuclear energy replaces most of the chemical energy from fossil sources with extremely clean and low cost power. The challenge mankind faces in getting to this goal is reflected in Miley's view of "Patience and Optimism," the title of his lecture when receiving the Edward Teller medal in 1995.
