Shiny but not enough, this is typical green washing. We need 100% decarbonation, not a few tiny percents.
These bubbles may be cool, it may contribute to somehow re-oxygenate the surface of the oceans, and it is still relevant when ships become fully electric.
But we need to replace the diesel machines with electric engines.
And why not real sails, proven to work since millennia, instead of those ridiculous rotative sail towers that need power and deliver so few results.
Real sails, and the boat's hull, must be photovoltaicized to provide power to batteries, the electric engines, and water hydrolysis machines that can store hydrogen as clean fuel for fuel cells.
Lots of work ? Yes, but 100% decarbonation is the minimum we need to reach.
Renaud Janson I'd say any improvement on existing performance is to be welcomed - especially those that can be retrofitted and don't require new ships to be built. Fully renewable and non-polluting is the ultimate goal, but AFAIK there's no practical solution to that for the shipping industry at present.
Rhys Taylor Renaud Janson - Perhaps if the rotating sails were powered by an N Machine type device. This was developed by Bruce DePalma, but tested in India by Paramahamsa Tewari.

We need better, quieter technology that doesn't disturb marine life; especially whales and dolphins.

Renaud Janson - Well said.

ReplyDeleteAs I understand it, conventional sails are not practical to retrofit onto existing ships, though kites might be a way forward. I think the rotating "sails" are weird but interesting; I'd like to see how far they can be pushed. They have the advantage over conventional sails of working all the time.
quora.com - Why don’t modern civilian cargo ships also use sails in addition to engine power to reduce fuel consumption?
