A smaller version of the Rankine machine in yourownpower.com looks possible in principle, and I've seen a number of other suggestions that solar thermal plus heat engine of some sort should beat solar PV in terms of overall efficiency and cost.

So perhaps a very small geothermal power unit which is designed for these sorts of temperatures and low-delta-Ts might be the most practical to avoid much re-engineering.
