Hi,
This is off topic, I know, but I once saw an experiment with a yacht with a windmill instead of a sail. It could sail directly into the wind.
I suppose that as it didn't 'take off', then it was a waist of time, but interesting nevertheless.

I don't find it all that off topic. As someone who has played with wind power for nearing three decades now I have always found it fun to ponder on the practicality (or utter lack thereof) of it suse in different applications.
I think that for low energy non critical applications (supplemental power) its wellworth the pursuit of its use if the numbers remotely add up to being favorable. The problem I always find is the practicality limits that show up in the less than ideal situations along with the the realities of what those limits come from (cost, complexity, stability and service life footprints) and how often they do inevitably come up in normal real world applications.
For example. Since my place got switched over to a smart meter system a decade or better ago and my local utility company set up their website to allow us customers to view our power usage numbers I have tracked my average power consumption over the years and have seen a solid downward trend in my overall average day to day usage rates. In fact I am now at my lowest daily averages ever which are now down to about 25 - 30 KWh per day, a good 10+ KWH per day reduction from my peaks 5 - 10 years ago, even with the addition of an electric water heater a few years ago!
By those average daily usage numbers I should be able to run my whole place off a small 2 KW AE power system with room to spare. Unfortunately the reality is my actual hour to hour usage rates are nowhere close to ~ 1 - 1.2 KWH that those numbers suggest.
What they are now is a lot of .3 - .5 KWH spans with a few 5 - 10+ KWH peak hours from week to week. And even the recorded peak numbers not totally accurate either given that during those there are many times, where I know from personal monitoring, my short duration loads (a few minutes or more) are up in the several 10's of KW!
Total off grid RE power for me is totally impractical despite the outward appearance that my average power consumption looks to be well within the practical working range of such sources at this point simply due to the need to have the capacity for such high short duration (30:1 overhead) load handling.
