The design of this would probably rotate to catch the wind, reducing the efficacy of the photovoltaic cells - though since they're at various angles and only a small number can ever be in direct sunlight... you won't be drawing much power anyway. You could design it to have a motor take over and bring up the blades to face the sun whenever the wind drops below a certain point for a sustained period... but it would need to lock and thus have many, many more points of stress. That would allow it to repurpose when the wind dies. I'm not sure if the design can come out ahead, even given ideal materials, my power generation knowledge peters out after the mid seventies.

Unless we bring out a pulse laser, or we needed the tight focus, or the laser had a specific frequency that makes it a more effective weapon against certain armor, etc.SinbadEV wrote:correction, not as efficient as a mirror and a large magnifying glass.AF wrote:Not as efficient as a mirrorsmoth wrote:solar powered laser?
