An electrical power generation and distribution system 1 for an aircraft comprises at least one heat source 2,3,4,5 and a thermoelectric generator 6,7,8,9 arranged to receive waste heat from the at least one heat source and to convert the waste heat to electrical current. The thermoelectric generator is in electrical connection with an electrical distribution bus 10 which is operable to supply power to aircraft electrical systems. One or more of the heat sources may include an engine exhaust section. One or more of the heat sources may include an auxiliary power unit. One or more of the heat sources may include an environmental control system. One or more of the heat sources may include a fuel cell. The thermoelectric generator may comprise one or more solid state thermoelectric elements (3, fig. 2). The thermoelectric generator may comprise alternating elements of n-type and p-type conductive connectors. The thermoelectric generator may comprise an infrared photovoltaic device.
