Transactions of the Symposium on Space Nuclear Power Systems, (5th) Held at Albuquerque, New Mexico on January 11, 1988. | National Technical Reports Library - NTIS
The PDF contains info on wheelguns, giant counterrotating flywheel hoops in space to supply power to SDI weapons, mainly railguns/particle accelerator cannons/free electron lasers that need huge amounts of power right now. Appears to expect to be trickle charged over time by a small space nuclear reactor (SNAP? atomic teakettle?). Also has an interesting microwave power beaming scenario from a nuke in mars synchronous orbit to a ground rover, high performance radiators, including a fabric heatpipe radiator, a curie point magnetic liquid droplet radiator, and other power conversion concepts.

Cultivation of an Obligate Fe(II)-Oxidizing Lithoautotrophic Bacterium Using Electrodes
Looks like they got rust making bacteria to live without iron, by simply supplying them electricity (electron substitute for iron oxides) and their regular diet of CO2. Which means you now have the basic foundation for a synthetic biofuel production system with electricity and CO2 inputs, provided you can tweak the bacteria to output biofuels directly like alcohols or oils, to be skimmed from a vat.

Phys. Rev. Lett. 109, 126806 (2012): Cloaking Core-Shell Nanoparticles from Conducting Electrons in Solids
Could this potentially be used as a high temperature superconductor alternative (or at least a super high conductivity material with very low resistance), since if you trick the electrons into believing that there is nothing hindering them, there might be no resistance?
