CPI numbers came out this morning, and producer prices are due out tomorrow. I'll be doing analyses for both, and your question is sure to figure prominently in the framing.
The idea of wind power to move ships obviously works, but the surface area needed to generate the necessary forward impulse has to be huge relative to the size and load of the vessel
Even at that the only time engine power and wind power could be used simultaneously is when running before the wind. When tacking or sailing into the wind a sail develops forward impulse by acting as an airfoil, using the shape of the sail to create a low pressure region on one side. However, that would be counteracted by forward impulse from the propeller, which would force air into the low pressure region and cancelling out the wind generated forward impulse.
Ships are one instance where solar cells would be a better option. Because they would transfer energy to the propeller the same as the ship's engines, so the two impulses are complementary.
I looked it up and now I know that wind and solar are actually being studied. But I don’t see anything that’s currently feasible for making a noticeable difference. The article implies that “politics” is the only thing holding us back from a zero emissions economy. They just keep the lies coming.
Will the same thing happen here ? Deflation.
Probably.

Do you follow MIT Tech? This article made me roll my eyes so hard. https://www.technologyreview.com/2023/07/11/1076080/un-climate-goals-global-shipping
I used to. Had to stop when the Babylon Bee was giving better information.
😆I don’t know if you read the link , but it says that they want to reduce shipping emissions by “slowing down ships and adding sails”. 🤣
I did see that. Hence the Babylon Bee reference.

Which do you feel is better for submarines?
The Babylon Bee says solar cells but I have always felt that running on the surface is best accomplished at night.
