We have been exploring whether Mark Heigh’s Gili speed boats could provide a suitable setting for a toroidal-propeller trial. The first question is compatibility, not publicity: hull, engines, gear ratio, shaft or outboard arrangement, normal operating load and the routes the boats actually run.
Fast island boats carry people who depend on predictable handling and dependable maintenance. A pilot therefore needs manufacturer involvement, a qualified installer, insurance and safety review, a spare-parts plan, and a clear stop condition. No efficiency objective can take priority over those basics.
If the right configuration is identified, we would compare the present propeller with the candidate configuration over repeatable conditions. The useful record would include speed, fuel, noise, vibration, handling and crew feedback—not just a single headline number.
Draft note: this is a proposal under discussion. It does not state that a propeller has been supplied, fitted or tested on a Gili vessel.

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:
