Energy Sources & Conversion
An Overview of Energy Conversion Processes
The processes which convert energy into useful forms have limited thermodynamic efficiencies, typically only 10-40%. This means that typically 60-90% of the input energy becomes waste energy. Often significant waste materials are also produced.
|Sample Reaction||C + O2 -> CO2||n + U-235 -> Ba-143 + Kr-91 + 2 n||H-2 + H-3 -> He-4 + n|
|Typical Inputs (to Power Plant)||Bituminous Coal||UO2 (3% U-235 + 97% U-238)||Deuterium & Lithium|
|Typical Reaction Temperature (K)||700||1000||108|
|Energy Released per kg of Fuel (J/kg)||3.3 x 107||2.1 x 1012||3.4 x 1014|
