energy transduction processes offer examples of elegant machinery, made of
earth-abundant materials, that operate efficiently and essentially isothermally.
Moreover, biological systems exhibit repair, self-assembly and replication –
features that so far remain elusive to human-engineered devices. Biological

energy technologies include catalysts for O<SUB>2</SUB>/H<SUB>2</SUB>O,
H<SUP>+</SUP>/H<SUB>2</SUB>, CO<SUB>2</SUB>/CH<SUB>2</SUB>O redox reactions,
reactions involving making/breaking carbon-carbon bonds, the redox chemistry of
nitrogen, and many others. Focusing on solar energy conversion, photosynthesis
inspires us to imagine technologies that would convert solar energy to fuel at
rates commensurate with human use. Aspects of photosynthetic machinery that are
important to future solar technologies include energy transfer, photoinduced
electron transfer at molecular heterojunctions, protective mechanisms, and
control networks. In addition to the design, synthesis and assembly of
constructs that carry out such processes, artificial photosynthesis can define
