Our effort has been to open a conversation about testing toroidal propellers on Venice’s working water-transport fleet. The idea is not to impose a technology from the shore. It is to ask operators what matters on their routes: noise, vibration, handling, reliability, fuel use and the realities of maintenance.
Any serious proposal needs a defined vessel, a compatible propulsion arrangement, a baseline and an agreed measurement plan. The test must compare like with like and account for route, load, weather and operating practice. Only then can a performance claim be meaningful.
In a dense, historic city lived through on water, quieter movement could be a real quality-of-life benefit if it can be shown reliably. That makes Venice a powerful place for a measured pilot: one that is useful to operators first, and only then to a wider story.
Draft note: this records outreach and a proposed evaluation path; no vaporetto installation or measured result is claimed.

Here I tell the story of the people and processes that won the final debate of the 200th aniversary of The Oxford Union on the motion: This House Would Go Vegan. The effort was intended to shine a light on the arguments of Dr. Sailesh Rao and Gerard Wedderburn-Bisshop that insist we must include the Carbon opportunity Cost of deforestation, the carbon that can not be sequestered by forests that are cut down, in the IPCC and therefore national carbon accounting conventions. Including COC in Carbon accounting conventions shows that livestock is responsible for 87% of Global Temperature Change Potential and focusing on fossil fuels is actually speeding up climate change. The event allowed us to meet researchers at Oxford who argue for and against the position and yet we continue our work to find written arguments against the position which was won on the day. We are very Grateful to The Oxford Union for supporting this event and allowing us to use it to shine a light into this all important place. The story follows:
