Solar kills way more people. Roofing is the top 3 most dangerous jobs, any solar that goes up on a residential home is pretty much "roofing" but with even more stuff to trip over than a typical roofing job.

Zombie wind power thread? it's been four years?



I like this because it combines two technologies that I follow, vertical axis windmills and gravity batteries. ...and Bucky Fuller's favorite thing -- tension!

I do wonder about a free-floating hull like the FLIP boats, with a larger mass moving over a shorter distance. Maybe it would reduce down to a lake-shore diving platform with a derrick.

Nailed it.

Initial thought is I don't like it. There's nothing special about the weight being attached to the generator unless that weight serves double-duty saving cost or reducing complexity. The video didn't mention anything thing about that. As it is, looks like a more complex thing, and no explanation of how the design would reduce the LCOE (Levelized Cost of Energy).

Also, water is way more dense than air, so having the weight underwater is a disadvantage as far as efficiency is concerned. Those weights would be pumping enormous amounts of water as it gets displaced with movement.

I put this in the category of kite wind turbines.

Any second thought?

Firstly they don't use a VAWT. Imagine trying to exert force at arms length vs close held.

Putting the weight internal to a FLIP hull was my extrapolation. A sea-going installation would have a minimum [IMHO] of six positioning anchor cables (displacement plus torque). one guide cable for the operative mass, and one or more lift cables to transfer power. It might need two, one to lift and another to feed the generator.

And those HAWTs? They need a need a wickrerbill , or whatever they call those ribs on the noses of velomobiles, that is a blown Coanda nozzle on both sides. This would protect the leading edge, but would be localized enough to not reduce the overall efficiency of the blade. Prove me wrong.



I am totally intrigued by this. It looks like the ultimate weekend getaway/bolthole.

2nd thought is I don't like wind or PV as energy solutions because of their intermittency and need for much larger engineering projects to store the extremely diffuse power.

As far as renewables go, my instinct is to favor geothermal and tidal since these sources are reliable and can be integrated into the grid with less engineering.

Agreed on tidal and geothermal. I think the gravity battery answers some of the shortcomings of wind.
