Grav-nets, like those in Niobe, are obsolete technology. Though they retain their charge for several hours after they lose power, they can't easily be modified once they've been built into the deck plating. Over time they're likely to drift away from 1G and can't be fixed without actually lifting the deck plating and exposing the net. Variable grav-plates can be modified through the ship/station's computer, but don't hold their charge for more few seconds. |
