Subsea Power Generation from WITT Energy

WITT Energy offers a new unique solution in energy harvesting and portable power generation. By utilisation of 6 axis of motion, a WITT device can take the energy generated from all types of motion.

Whether this is from kinetic motion, wind generation or wave motion, it doesn't really matter, as the WITT device brings all energy from motion to a single point for power generation. The application potential is vast, as is shown in the WITT Energy launch video below, there is certainly a high level of interest in WITT. 

From launch to testing the video below picks up with Professor Philip Wilson of Southampton University for the first prototype testing.

Exploring how rotational energy can be taken from the environment around us and turned into electrical energy. This testing clearly shows just how scalable the WITT device could be. From utilising wave energy, power can be provided to assist offshore platforms in powering lights, instruments and communications.

Subsea and water farm are the areas where WITT Energy sees demand for remote and renewable power sources. To re-create the subsea conditions and run WITT in a practical setting WITT Project Manager Claire Read paid a visit to Solent University.

To obtain real-life data and performance measurements, WITT was submerged in the university's 60m towing tank. The tank creates subsea currents which induce movement within the pendulums which in turn rotates a single directional shaft to generate power. Join Claire to see WITT in action.

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" -

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

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.
