Deliver us the moon electric cables rotation engine generator#
Rather than having a power station on the moon, why not have the cable itself be the power station.Īn electric generator consists of a conducting coil moving within a magnetic field.
Long story short, I believe it is more plausible story to beam energy than to send it via cableĪ few others have addressed the "how" of it, so I'll try to take a stab at the "why" of it. We kinda resolve it by pushing the power on high voltage to the cables, but you are still going to lose some power.
The power cables lose their power on the go. So, you do not only need 4 space elevators, you need to build space elevators using curved cable, which is another level of the whole engineering issue.īeing in energy field, I have to tell you sad news. You need to somehow resolve variable distance of Moon to EarthĪs stated in the comments, the Moon changes its distance relative to the Earth by 10 percent. Googling "distance to Moon" gave me 384400 km. (Googling Space elevator length gave me 60000 miles = 96560.6 km. If my calculations are correct, you need four of them, possibly connected to each other. However, for the sake of this question, let's assume that the cable material is a superconductor, and has the adequate properties (tensile strength, etc.) to withstand the rigors of satellite-tethering! Now, as several people mentioned in the comments, I get it that a cable would be no better as it too would lose power during transmission. I asked this question primarily because it was stated in the above question that 'beam'ing energy from the moon to earth would have a pretty bad efficiency. What other reasons could prevent this from becoming a reality, or what type of improvement in technology would be required to make this achievable?
If the power cable was fixed at a stationary point on earth, it would be at one of the poles, I guess, otherwise the cable would wrap around the earth as the moon revolves. I was wondering if instead of 'beam'ing energy from the moon, could it be possible to extend a power cable from the earth to the moon? Related Question : Can we 'beam' energy from the moon?
