I'm planning a to build a solar-powered robot. Efficient solar cells, motors and electronics will of course be required. Efficiency has never been much of a concern in my previous hobby projects.
Can anyone suggest any good books / papers / websites / whatever on power-efficient electronic and mechanical design? It's not just low-power, as I'll have around 0.5 sq ft. of solar panels, so at least a couple of watts to play with (during full sunlight), but I want to make the most of that power.
