Interesting wind technology

This was on a Cop26 news item but could be relevant to a moored boat?

Windswept and Interesting

Says he has 1.6kwh running.

A quick look at a Rutland 914i shows a few hundred watts?

Might even work if you were offshore sailing in a straight line?

I saw this in Reporting Scotland half an hour ago. It occurred to me that it's a complicated way of doing something simple. When the wind falls the whole lot ends up on the ground and will not relaunch by itself when the wind returns.

The effective diameter of the rotor is large compared to a boat wind generator like the Rutland, but that is all that it has going for it.

Ingenious? Certainly, but practical? Not so sure.

It's old hat. My PhD supervisor in the 1970's (there was an oil supply crisis at the time) had the concept of a kite supporting a wind turbine in the jet stream. We all thought the jet stream was a thing that blew steadily and stayed put. Apart from that, I thought it was ingenious. We never got round to the question of how to get the assembly up there.

IIRC during the 2nd world war the only military accidents on US soil were caused by Japanese balloons loaded with explosives which were sent into the Jet stream, which then brought them over North America.

Any wind generator must create

See Fu-Go balloon bomb - Wikipedia. Totally ineffective in any military sense, but they did cause one incident with civilian casualities.

Apparently Operation Outward - Wikipedia was more successful!

Minesto are looking at underwater, tide driven "kite" technology:

Saw it on Alluring Arctic on YouTube.

My understanding (not much) of yachting was to move forwards through the water, that contraption looks like it may pull you Backwards!

There's a thing called kite-sailing, and that was my thought too
