Before revision: He predicted that a power input of 1,900 kW would be needed and calculated that the D-D and D-T reactions would generate 9 ,000 kW of fusion energy, of which 1,900 kW was in the form of neutrons.
After revision: He predicted that a power input of 1.9 MW would be needed and calculated that the D-D and D-T reactions would generate 9 MW of fusion energy, of which 1.9 MW was in the form of neutrons.
