Eutectic fluoride mixtures of alkali and alkaline earth metals posses extremely high thermal storage capacities, and are therefore suitable for space heating as well as for powering heat engines. Their melting points ranging from 449 to 832° C are well adapted to any high level heat supply. The compounds are of high chemical stability and show no corrosive action with stainless steel. In order to make efficient use of the stored heat, good thermal insulation and controllable heat transfer are achieved by a multifoil insulation jacket with a controllable hydrogen filling. For powering engines energy transfer is realized by heat pipes.
