Any surplus heat from Aneutronic Fusion need not be wasted. Instead it can be used directly for space heating in winter and air conditioning in summer. Many European cities have central space heating systems. It can also be used to heat/cool greenhouses and for aquaculture, especially in cold climates. If FF is safe enough to be built in urban/suburban areas space heating and cooling would be both easy and economical and would improve the economics of a FF power plant.
