You loose around 30% of energy from the sun through the atmosphere, plants are about 3% efficient at turning light into sugar, humans are about 25% efficient at turning food into mechanical energy, so you are only about 0.525% efficient at turning energy from the sun into human power on earth.
So you this device is only about 0.231525% efficient at turning solar power into usable work.
Assuming 80% efficiency for the electric variant, 20% efficiency for solar panels, 90% efficiency for robots to turn electricity into mechanical work, that’s 14.4% efficient. Then it’s like 62.196307 times more efficient to become a solar electric android and pedal on it in space.

A nice place to discuss rumors, happenings, innovations, and challenges in the technology sphere. We also welcome discussions on the intersections of technology and society. If it’s technological news or discussion of technology, it probably belongs here.
Remember the overriding ethos on Beehaw: Be(e) Nice. Each user you encounter here is a person, and should be treated with kindness (even if they’re wrong, or use a Linux distro you don’t like). Personal attacks will not be tolerated.
Adding to this: This is basically turning solar energy in stored energy. Solar power-> growing Plants-> Man eats Plants-> kinetic energy-> storage
Simply take a solar panel and a battery.
