TRL 3 - TECHNOLOGY READINESS
THREE - Level 3 – Critical function, proof of concept established
In the case of the Elizabeth Swann, we need to provide a stable hull, for a lightweight superstructure, on which to mount the PV panels that track the sun. To begin with, this is a given - using a simulated superstructure fixed to a workshop bench. We also need to be sure that electronic reading and motor control for alignment with the sun, works. Thus, mounting of the photo-resistors is critical to success of the experiments, as is the drive-shaft, motor and gearbox, that provides the torque to rotate the PV wings against normal wind pressure.
SCALE - The TRL scale is a metric for describing the maturity of a technology. The acronym stands for Technology Readiness Level. The scale consists of 9 levels. Each level characterises the progress in the development of a technology, from the idea (level 1) to the full deployment of the product in the marketplace (level 9).
