When plants grow too tall, they start to take over a domestic environment.
Today’s invention is a plant pot stand which can measure the height of the plant placed on it (say daily, by using a photocell to spot the shadow of the plant on the adjacent wall at a fixed time each day). It would then, very gradually, reduce its own height to compensate -keeping the plant’s tallest point at a fixed vertical location.
This would be achieved by having a very slow-rate screw built into the stand’s telescopic column. Rotation of the stand on the screw would be via a battery-driven electric motor and a suitable gearbox.
