Ref 1 provides an overview of challenges in energy technology that could be addressed by nanotechnology. Miniature biofuel cells could be a means of converting stored bioenergy to power, or alternatively of harnessing hydrogen gas from inexpensive, readily available materials such as sea water for a source of fuel when needed.

achieving several hundred nanowatts of power, in which tethered biological enzymes at two electrodes first strip a hydrogen ion off glucose and then combine the H+ with oxygen to create both power and water. Nanotechnology is currently revolutionizing small battery technology -- see for example Ref 7.

The overall goal was to use clean, renewable, and biodegradable resources and methods to reduce dependence on hydrocarbon fuels at a scale useful to small, remote villages. The general idea was to develop first "a better bug" to convert solar energy to harvestable hydrogen gas.

Crazy thoughts and cow parts Having narrowed the focus to moderate-scale hydrogen production-means yet to-be-determined -- Focus Group 8 re-convened Friday afternoon to identify current bottlenecks that might yield to innovative approaches. Envisioning eventual depletion of hydrocarbon fuel resources, the group focused on methods driven ultimately by sunlight.

The other was larger in scale, laying out in concept a complete, nearly closed system powered by sun and wind energy, and generating usable hydrogen, oxygen, and fresh water. It incorporated the novel use of reusable cobalt salen to capture the problematic oxygen.
