To answer my own question, using numbers from [1]: U235 = 79,390,000 MJ/kg 1 kWh = 3.6MJ 1kg u235 = ~22,000,000kWh 1g u235 = ~22,000 kWh of energy For th

To answer my own question, using numbers from [1]: U235 = 79,390,000 MJ/kg 1 kWh = 3.6MJ 1kg u235 = ~22,000,000kWh 1g u235 = ~22,000 kWh of energy For the HB11 reaction: 1000 / .014 = ~21,000 kWh/g So about the same as current fission. Except without the nasty byproducts.
