As a mechanical engineer with experience in flywheel energy storage and wave power generation, I can't see what the excitement is about: "The WITT system of this size is approximately 250mm in diameter and
is capable of generating 5W" - https://www.rs-online.com/designspark/download-attachment/2b83e1e4-6add-11eb-8d22-42010a00001f_Smart%20Subsea%20Power.pdf

A good automatic watch would be cheaper surely. This does not help with climate change!

@billrayner Thank you for taking the time to post a comment, the WITT team recognise a healthy dialogue is always good As a company with a unique patented system (granted in Europe, USA et al) that takes 6 degrees of motion from two orthogonal axes to a single output we needed to identify a first product to market, having a system sealed from the elements that can produce 5 to 10 watts sub-sea gives us unique advantages in providing persistent power, which at 5 watts for 90 days equates to 10,800wh (at 12 volts 900ah), this is useful power which has been confirmed by multiple entities. The WITT team believe a fundamental for addressing climate change is knowledge, and collecting data where it was previously unavailable, this a different need to applications where wind or sea turbines are used. As an engineer you must appreciate that the ability to scale is vital, and the power output from a scaled up device is not a linear function. At present we are neither using wave power nor flywheel energy storage, although both of these are of interest to us. We believe there is a gyroscopic effect with the flywheel which may counteract the movements for kinetic energy harvesting devices. We also note you have done a thesis on flywheel storage, interesting technology, there was a presentation at Ocean Exchange in 2013 by Thorndon Bearings on this.
