“And if there is no wind..................................”
And if you had read the article..........................
According to Zha, this makes for a very effective wind propulsion system
As one who did— it did not address how these would function in major sea storms encountered quite freqently. The design is called “at right angles” to wind. When in these huge waveforming storms, large vessels need to head into the wind, under power. Turn into the wind. Does not say how they can be non-deployed or stored. Perhaps it is dealt with- but it would have to be proven for the expense of not destroying a vessel. Insurers would be in the equation, of course.
I tried to read the article but my BS meter kept getting in the way.
“And if you had read the article............”
Why?
We had a headline to go by.
