Inductive Boots that passively recharge your suit while standing on a powered grid.

It could be mid-to-late game convenience upgrade. It could be a tool (like bottles) that costs gold (since it probably uses superconductors), and when that tool's in your inventory, the boots work.

There were several ideas about implementation when I posted this to the subreddit:

• It could charge more slowly than a medical room or survival kit, or just prevent the suit from running out.
• Ownership-wise, if the player with the boots owns the power source on the grid (reactors, etc.), they can charge; this prevents people from draining enemy-owned grids.
• Instead of something the player equips, there could be a transmitter block. This could be like the gravity generator, with a set range within which you recharge, or just a block that enables that grid to recharge you whatever its extent. One person thought this could be an upgrade module for the antenna.
• A couple people thought it should be limited to only certain blocks, like interior blocks and stairs. I would add catwalks to that list, but I'm not sure it's necessary to restrict charging to only the interior/'finished' areas of a grid.
• One user suggested this could apply to landing gear as well, which would allow miniaturization of drones that otherwise don't need connectors (without having to connect them with a rotor...).
