- Mimic orbital motion for electrical generative purposes
If the earth has been revolving around the sun almost perpetually, we should mimic this motion for electric generative purposes or is it not feasible?
Are you referring to leaching orbital energy from the Earth to provide electricity? If so, there's not really a feasible way of doing so.camptent said:If the earth has been revolving around the sun almost perpetually, we should mimic this motion for electric generative purposes or is it not feasible?

I wonder what you really mean by that?camptent said:Wow this reply just opened up a Pandora's box for me, this would awesome
Please don't spend a lot of time trying to figure out how to generate electrical energy from the rotation of the Earth or its orbit around the Sun. I spent a little time on this (before finding PF), and eventually concluded correctly that you cannot do this in the Earth's isolated system. You would need some external system (a giant gorilla the size of the solar system) who could "hold" objects stationary to interact with the orbiting planets. Not going to happen.camptent said:Wow this reply just opened up a Pandora's box for me, this would awesome
So you're responsible for that damned Gorilla? Doesn't he do the cattle mutilations?berkeman said:Please don't spend a lot of time trying to figure out how to generate electrical energy from the rotation of the Earth or its orbit around the Sun.

It's good to be creative, but you need to learn enough basic science to be able to figure out "non-existence proofs" quickly for creative ideas that will not work. That gives you more time to devote to other ideas that do have a chance of working.

I think there might be some ways to try to generate power from the solar wind and orbital rotation, but there's that pesky issue of how to get that power down to the Earth's surface (similar to orbital solar power generation).
Electrical energy can be extracted from orbital motion using electromagnetic induction. This involves moving a conductor through a magnetic field, which generates an electric current. In the case of orbital motion, this can be achieved by placing a conductive material, such as a wire loop, within the magnetic field generated by the orbital motion.
Potential sources of orbital motion for extracting electrical energy include satellites in Earth's orbit, planets orbiting stars, and moons orbiting planets. These objects all move through a magnetic field, which can be utilized to generate electrical energy through electromagnetic induction.
The efficiency of extracting electrical energy from orbital motion can vary depending on various factors such as the strength of the magnetic field, the speed of the orbital motion, and the design of the system. Generally, electromagnetic induction is a relatively efficient process for generating electricity, but the specific efficiency of extracting energy from orbital motion would need to be determined through experimentation and analysis.
Some potential applications of extracting electrical energy from orbital motion include powering satellites and spacecraft, providing energy for space missions, and generating electricity in space-based habitats or colonies. This technology could also be used to supplement or replace traditional solar power systems in space.
Some challenges and limitations of extracting electrical energy from orbital motion include the need for a strong magnetic field, the complexity of designing systems to capture and convert this energy, and the potential for interference or inefficiencies in the process. Additionally, the amount of energy that can be extracted from orbital motion may be limited by the speed and trajectory of the orbiting object.
