Cycles for producing electricity from heat utilizing the magnetocaloric effect have been considered. A thermomagnetic generator producing electricity directly without a mechanical interface has been studied analytically, with emphasis on low temperature (below 400 K) applications. Power density and efficiency higher than previously reported in the literature appear achievable. Practical machines may be possible, further study is justified. Areas for future investigation include identification of optimum materials and verification of heat transfer correlations. Capital cost for a thermomagnetic generator is estimated to be comparable to the cost for commercially available low temperature organic Rankine cycle generators. Cycles utilizing chemical reactions to change magnetic properties have also been considered. Suitable reactions have been identified, further study is required to quantify performance.
