Could a giant radiometer generate electricity ...
Several comments lead me to understand that a Crookes radiometer (light mill) would be inefficient according to the Carnot cycle principles governing engines, but I couldn't find anything I was confident with. Still, people have tried to do more with the idea. A Swiss inventor made a clock out of a light mill.
How does a Crookes' radiometer work? | HowStuffWorks
How does a Crookes' radiometer work? A Crookes' radiometer has four vanes suspended inside a glass bulb. Inside the bulb, there is a good vacuum. When you shine a light on the vanes in the radiometer, they spin -- in bright sunlight, they can spin at several thousand rotations per minute! The vacuum is important to the radiometer's success.
