What types of sheilding technology does the imperium posses, do they still have power feilds, can void sheilds be used for planetary defense. Is the technology used in personal powerfields eg refractor, conversion and displacement used anywhere else
How about radiation/magnetic screens, can/does the imperium use these on ships or worlds were radiation would otherwise kill everything, what i'm getting at is somthing like the effect of the earths core, but instead of spinning liquid iron somthing more like jupiter's spinning metal hydrogen core would be used, or is this beyond the adeptus mechanicus's expertise

Not entirely sure that I agree with the move, but for the moment let's leave it here... Indeed, I wonder if it gets anything other than this generic reply? I'm going to hold off posting since I actually want to see what the others have to say. Ultimately this gets into an important consideration of the project. I expect to see "Well, it doesn't say that planets have void shields. Only ships and titans can have void shields. People where displacer, conversion... " etc.
But if the technology exists then there is every reason to believe it can be exploited elsewhere...

I don't think anyone has anything to say, but i would really like to know your views on the subject, as you say it is quite an important issue. And i know of one sheild used on a planet to protect an entire hive city, and was impervious to ground weapons true mr Abnett had a hand in the writing of this, but please try to temper your....mmm... mild sceptisism of his credentials  |

I think this is a bit of a non-question, to be honest.
They're shields. I'm aware that the various types probably are slightly different in operation, but shields are shields.

sheilds are sheilds, yes indeed  , but sheilds are not feilds and they have different applications, which are better at stopping energy weapons, which at stopping projectiles and missiles, does a void sheild protect against radiation, can powerfeilds create a sealed enviroment as in containment feild, tractor beams are feild devices are they the same as void sheilds . The various applications for these devices is enormous but you seem to see them as only a means not to get shot. True, if thats what we are talking about then i suppose it does't matter, sheilds are sheilds, but i was hoping that someone might have a new take on how they are used and what their properties might be  |

Sheilds are sheilds? Let's get one thing straight... they're called "Shields". S h i e l d s. Not sheilds. Shielding. Not sheilding That said, I don't think it's much of a non-question, but... frankly, I'm not that interested in the subject that I would bother making some kind of overview of Imperial shield types. I would say this however... Void shields would stop radiation. Displacer fields and conversion fields would not. The type of shields in Necropolis would be extremely rare, in my opinion. This is probably DAoT- tech, since no other cities seem to have it. I wouldn't object to an ancient Imperial world in the Anargo sector having it though. |

From RT, not sure if these are still used...
These fields act like shields.
Conversion field
Coverts kinetic energy to light, and works on las-guns too (?!)
Powerfields
Used on weapons they disrupt the target's matter making it easier to destroy the target.
Refraction field
Slips projectiles. Similar to a 'forcefield'.
Displacement field
Not really a field it I remember rightly. A sensor detects a 'hit' and activate a teleporter.
Void Shields
On titans, not sure. Sounds like there is some kind of warppery. It may be void as in 'hit is void'.

I hadn't realised it was kinetic energy only, though the photons in a lasgun blast would have kinetic energy as they are moving and do have mass. This field actually powers itself to some degree does it not
Did'nt orks use power field banks on their gargants as protection, how many types of power field are their
Can power fields be used for mining
Are these fields limited to personal use or can they be made bigger, maybe to shield a city or would a void shield be better for that.
It voids the hit, a void shield can be hit by any thing and will stop it by overloading itself, which its designed to do, i think it might well be warp based. This is a static/solid field of immense strenth, you can see void shields when they are switched on as a kind of rainbow effect i think

If you are looking to generate a protection field (of any type) you must consider the energy needed to not only project the field, but to maintain its integity. to cover an entire city would perhaps cause too much of a drain on the energy production facilites available. Personally I think void shields on Titans are pushing it.

The obvious reason a void shield couldn't protect a city is that it the geometry has to be spherical or ellipsoid and you can't project a spherical field around a city because of the ground. The problem is, Titans suggest there's some way around that problem. Shield geometry may still explain this. Your options for a ship based shield are presumably spherical or ellipsoid or closely following the hull. If we assume a spherical field, then you've got a roughly 3km diameter void shield. Even if you can project a hemispherical field (perhaps by pushing in the bottom of the sphere so the city is actually sitting under the bottom of the bottom half of the sphere, which has been punched in to give a bowl shape over the city), this diameter is insufficient to cover any reasonable hive city.
I'm not sure this works because of the Ramilies Star Fortress - if you can cover that monster with shields, one would think you should be able to cover a city.

I was basically thinking of the city shield in Necropolis, whether or not that was a void shield is debatable, but would it have to be a void shield. and why does it have to be spherical, why cant it be a dome.

And let us not forget the city in Execution Hour where the governor's palance also had a shield of some form... Erm, not much more useful to add at this point I'm afraid. |

Oh, it certainly could be a dome. The question was why some hives have them and not ALL hives. For that matter, why not all imperial installations of value?

There is a nobles house in Malleus that is protected by a void shield I believe. Eisenhorn gets to blow it up!  I hate the idea of shields in many forms of sci-fi  |

Oh, it certainly could be a dome. The question was why some hives have them and not ALL hives. For that matter, why not all imperial installations of value? Unfortunately there are a number of plausible and simple answers to this: - Someone didn't think of it before.
- They don't have the STC (on that world).
- The adeptus mechanicus are not willing to enter into a 'franchise' with the world and/or specific hive for some slight in the past or until certain economic/whatever comprimises are made.
- Suspension of narrative disbelief.
Incidentally, it might make more sense if ground-based installations actually have 'two components' to the shield. The first is the primary field generator and the second are peripheral systems which actually create a hemispherical 'dome'... they kind of 'invert' the field and, just as with a closed harmonic instrument, return the wave back on itself reinforcing it. Thus in some ways one could think of a ground shield being stronger than a similarly rated 'space shield'. This might make up for any atmospheric (or whatever) considerations that could be 'hand-waved' into position. |
