3. materials which convert fissile nuclei to fertile nuclei. 4. fission products which absorb neutrons without contributing to the chain reaction fission process. When replacing my single glazed windows with double glazed, I 1. reduce heat lost by radiation 2. reduce heat lost by conduction 3. reduce heat lost by convection 4. None of the above are correct. Chimney vents waste gases and provides draft for new oxygen.
Electric power comes from central station -either fossil, nuclear, wind, or water powered.
If combustion occurs, it occurs at central station, not at home. Electric heating can occur right where needed - doesn't have to be transported from furnace to place of need. But lot of electrical energy lost on way from powerplant to place of need. Does not appear wise to use up fuel to, produce fuel. If we could tap all of the solar energy captured in the corn without using fossil fuels, then corn would be a useful supply of fuel.
