Thermomagnetic generators convert heat to electricity directly, without a mechanical interface. Numerical analyses of regenerative thermomagnetic generators have been performed for three materials. Power density and efficiency higher than previously reported in the literature appear achievable. Practical machines may be possible, but further study is required. Some possible configurations are discussed in this paper. Areas for future investigation include identification of optimum materials and verification of heat transfer correlations. Capital cost for a thermomagnetic generator is estimated as comparable to the cost for commercially available low-temperature organic Rankine cycle generators. 15 references.
