PEN RECOVERS INK FROM PAPER

Iron Imperative
Pen can recover the ink it writes with. 
Inspiration from Nature
Phalaropus Lobatus drinks water by opening and closing its beak instantaneously. This creates pressure due to the surface tension of water.

Problem Statement
Paper, over the years, has become largely recyclable. But ink left in used-paper is wasted even when the later is recycled. If ink could be recovered, the whole process of recycling paper would not be needed. A set of pen and ink needs to be designed which can write and erase over and and again.
Nature Review
Red-necked phalarope (Phalaropus Lobatus) can perform a highly sophisticated form of capillary action called Capillary Ratchet. In this process, a pressure is built on the surface tension of a liquid, through instantaneous intervals of opening and closing of a device (beak or nib).
Technology Review
Classic fountain pens use capillary rubber cartridges to store ink. Now that the charged fluids have already been invented, molecular-level oscillations at the tip of the pen can create electro-magnetic pressure on ink particles which are pre-encoded to communicate given pen. Such pen would write like an infinitesimally small ink jet printer but an ink that can be galvanized and recovered.

Nature Gadget
Ink is imbued with electromagnetic charge (32) which remains dormant while writing but gets activated by electromagnetic capillary ratchet action (21, 16, 19) of the nib (34). Nib sucks ink back into a neutralising compartment (11) where it (ink) can be stored and reused. Every pen has a unique (31) algorithmic pattern of its capillary action (like morse code) and it can upload written and recovered history (34) in a binary format on cloud storage. It provides a backup for the conventional paper notebooks.
