Shipboard wireless power

I use this in my game for on ship robots, cargo containers that need power, etc. Helps eliminate bulky batteries and what not. Just an interesting additional high tech flavor for the game. I consider it an advanced form of this: http://en.wikipedia.org/wiki/Resonant_inductive_coupling
 
Inductive power is fairly cheap and common today (I have some table lights in my flat that are recharged by sitting on the recharger rather than plugging into it (hence ugly plug), so I'd say this is a nice idea.

Not needing a cable connector makes things easier; I'd imagine that at TL12+ you've probably got a resonably smart computer in a lot of cargo containers (combined RFID tag, handling/hazardous goods data, and manifest/customs paperwork in one panel) and something like this in the cargo bay floor is a nice way to power them without having to run trip-hazard cables everywhere or else shift a twenty tonne container if you find you've put it down six inches short of the socket.
 
So what stops other devices from leaching their power off the field? (Note: not even close to being a physics geek. Pity, that.)

The link explains. But, it isn't like Tesla's power transmission. It is ~80% efficient today.
 
Just because they don't cause any (documented or recognized) health effects in humans doesn't mean they won't set an Aslan's teeth on edge, or give a Virushi vertigo.

Unless those species have built in resonant coils, no problem.
 
Quantum entanglement could also be used at high tech levels to transfer power from a power source to anything, theoretically no matter what the distance. Haven't a clue about bulkiness though of the "entangled" receiver on a robot or what ever. Not to mention the cost.
But just imagine having a large power plant on some planet somewhere, then have the M-drives entangled to the power plant, maybe even a J-drive.
Large engines on a ship, but the power plant or fuel source on a planet many parecs away.
hmmmmm..... that would break the rules though.

Well, a lot of species on Earth have magnetic sensitivity for navigation... there's no reason why some alien races shouldn't...

Not the same thing. Having sensitivity won't cut it as they would be messed up by other EM fields that are stronger. So, they wouldn't be able to function in any modern society...
 
You can't say that for certain - unless you know of all alien races and their physiology...

I was born with a squint and, as a result, had several operations on my eyes. I was told by "experts" that it was only bright light I'd need to worry about and that'd only be a for a week after the operation... they didn't believe me when I subsequently told them that I couldn't go near some fluorescent lights because of the flicker rate - particularly when you get multiple devices together.

It's not the frequency of the device, it's the frequency of all the devices together that might cause problems.

Not saying it would, just that it might.

After all, some people have reported more frequent headaches when near overhead power lines...?

Sure I can. It isn't about physiology. It is about electronics & physical laws. IF the wireless power effects them, other EM would also. Inescapable physics not, physiology..
 
So you're saying, that by your logic, that I couldn't handle any light (ie that band of EM radiation) after my operations? I beg to differ... I could handle bright light after a few weeks, but the light flicker gave me headaches for months and months after... or are you saying that all such tubes are dangerous for human use? Incidently, I used microwaves, computers, video equipment and lots of other electronic devices without harm or discomfort...

Sensitivity can be limited to certain ranges and/or types of EM radiation, but also when such devices start to wear out they emit more EM radiation than when they're new, which may lead to other problems.

With such new technology, you cannot be sure that there are no such influences outside of their intended range without stress and endurance testing to induce component wear.
 
I doubt that it would be possible to design a standard "Goldilocks ship" with
an artificial environment that is comfortable for all species. There will be dif-
ferent gravities, different compositions of the atmosphere, different tempera-
tures, different lighting, ships with and without wireless power ... the majo-
rity of all artificial shipboard environments of all species is very likely to be
harmful for at least one other species.

A species with the electromagnetic sense of a hammerhead shark would pro-
bably be unable to serve on a ship with a wireless power system, so this spe-
cies' ships will have to use some other kind of system.

No, I'm not talking about you, unless you have coils in your body. I'm talking about being sensitive to to EM from power systems (since that is what the subject is). Do you know the difference?

Actually not. As, that isn't how this type of system works. It is NOT a broadcast system, a la Tesla. The field wouldn't enter the body of said shark in the 1st place... That's why even examples at TL 7 deliver >80% power to the receiver as opposed to a small fraction.

It may be, but I am not sure. A hammerhead shark's sensor can detect
an electrical signal of half a billionth of a volt, he uses it to sense the ra-
ther weak neural electric signals in prey hidden under a layer of silt on
the sea floor - most impressive. But this would be a question for a mari-
ne biologist, I do not know for certain how the shark's sensor works.

They detect weak EM electrical generated by the nervous systems of living organisms. That type of EM radiates in all directions. Hence, they pick up as it interacts with their receptors in/on the its body. The broadcast power systems doesn't radiate in that manner. It would effect the shark if it has an actual coil tuned to the frequency.
