Offshore wind power redesign key to adoption, says Irish firm A Dublin-based company with a modular floating offshore wind turbine design believes its design checks one of the most important boxes the deep-sea wind industry has yet to solve: Affordability. Rather than reducing the height of their turbines, building a wider, more stable base or trying to develop an entirely new method for …
is Manhattan really the global minima for wild goat bites?
While we're being pedantic, "global minimum".
Unfortunately it appears the ICD-10-CM only breaks this sort of thing down to "Bitten by other hoof stock" (W55.31) which is "applicable to contact with goats" and distinct from other sorts of encounters with goats, but does not distinguish between goats and, say, sheep. So it's going to be tough to get reliable numbers.
That said, you're certainly correct that the probability of a goat bite in Manhattan, while small compared to, say, the probability of encountering a pool of human urine, is still likely greater than the probability of a goat bite in, say, Queen Elizabeth Land.
This looks like a clever design, but moving elements and pulleys in those harsh conditions don't seem like a good idea.
If something fails you don't want the nacelle with its tons of oil other dangerous chemicals landing in the water.
To keep something that floats stable in rough seas you need balast. Lots of balast.
Finding cheaper and more suitable balast sources would seem like a better direction of research to me, but nonetheless it's good that research and innovation is happening in this industry not just on the blade and generator front.
Well, you really want something that is heavier than the surrounding medium to give a weight differential to make it an effective ballast. Seawater would have some benefits, but would not help in that respect.
What is interesting is that the main movement of water caused by weather only goes down 10 metres or so. Below that, any movement is mainly caused by currents, so maybe part of the solution is to go deeper with the supporting structure. Would probably still need to be tethered, though.
I can understand why some startup wants to flog this carp. The Bbc explains the challenge-
https://www.bbc.co.uk/news/science-environment-65500339
The government and private investors have spent £198bn on renewable power infrastructure since 2010. But now energy companies are warning that significant delays to connect their green energy projects to the system will threaten their ability to bring more green power online.
This is why our energy bills are so high. When they say 'government' and 'private investors', what the 'renewables' PR wing really means is UK energy bill payers because that £198bn has been added to our costs. And it's given us this-
https://gridwatch.co.uk/Wind
minimum: 0.388 GW maximum: 17.444 GW average: 7.821 GW
solar-
minimum: 0.001 GW maximum: 9.168 GW average: 1.166 GW
So 'renewables' have only cost around £22bn a GW. Nuclear costs around £10bn and doesn't have the intermittency problems. They're also far less vulnerable to off-shore storms that will turn floating wind farms into scrap metal. Funnily enough, our doom-ongers also confidently predict that we'll experience more severe storms that are more likely to destroy 'renewables' projects. It's kind of the sunk cost fallacy writ large, only with other people's money.
I know you spelt onagar wrong but you hit the nail on the head about wild asses predicting doom.
Sadly, they're everywhere-

Our overheating world is likely to break a key temperature limit for the first time over the next few years, scientists predict.
Researchers say there's now a 66% chance we will pass the 1.5C global warming threshold between now and 2027.
Ohnoes! We're melting! But the trillion dollar climate fear industry relies on garbage like this. Build windmills, save the planet. Nuclear power would be far cheaper and more efficient at producing cheap, reliable low carbon energy as the Finns just discovered-
https://www.statista.com/statistics/1271437/finland-monthly-wholesale-electricity-price/#:~:text=The%20average%20wholesale%20electricity%20price%20in%20Finland%20stood,indicated%20period%2C%20at%20around%20261.5%20euros%20per%20megawatt-hour.
The average wholesale electricity price in Finland stood at approximately 74 euros per megawatt-hour in March 2023, the lowest figure since October 2021. Less than one year earlier, Finland's wholesale electricity price reached the peak of the indicated period, at around 261.5 euros per megawatt-hour.
And mostly because of..
https://www.thenationalnews.com/business/energy/2023/05/14/nuclear-power-helps-bring-down-electricity-prices-by-75-in-finland/
The start of a much-delayed nuclear plant in Finland has helped bring down electricity prices by more than 75 per cent in the Nordic country.
The Olkiluoto 3 (OL3), Europe’s first new nuclear plant in 16 years, began operating in April and is capable of meeting up to 15 per cent of the country’s power demand. Nuclear made up a third of Finland’s total electricity generation in 2021.
Nuclear doesn't care about the weather, unlike neo-luddites like the Bbc who promote the 'renewables' scam. We've been warming since the end of the Ice Age, or even Little Ice Age, therefore we're doomed. Plants and animals that evolved in conditions where both temperatures and CO2 levels were far higher than today are somehow going to become extinct. Floating windmills that kill birds and fish are somehow going to save them from disolving in 'acidic' oceans.. which kinda overlooks the amount of carbonates in the oceans that will prevent that from ever happening. But it's a hugely profitable business, hence why pseudo-scientists realised at observed, empirical run-rates, we'd never hit the 2C doomsday level, and so dropped the target to 1.5C, which is within observed natural variability. And also far less problematic, even potentially beneficial.
But thanks to the Bbc's 'unique' form of funding, idiots like McGrath can afford to pay their energy bills because the Bbc extorts money from it's 'customers', just as the scum sucking parasites in the 'renewables' industry he promotes do. Rather than wasting billions more on floating bird slicers, this company should perhaps look at building floating nuclear power plants instead. These already exist, and our own Rolls Royce has plenty of experience in this sector.
Firstly, you haven't included decommissioning costs for nuclear power stations and the cost of safe storage of their high-level waste products for hundreds of thousands of years Understandable, because we haven't even started on that yet. Secondly, they're not yet vulnerable to offshore storms, but wait until the sea level rises!
The UK government has been trying to build a long-term waste repository for decades. The "green" lobby has campaigned against it, successfully, just because nuclear is "bad". Meanwhile we have a lot of long-term waste being kept in "temporary" storage, and nowhere to put it.
There's also the NIMBY problem. No-one wants a garbage dump in their back yard, and no-one wants a long-term nuclear waste repository anywhere near them. But we need one somewhere.
The USA has the same problem.
It's not a technical or financial problem. We know how to do it and the government is willing to spend the money. It's a political problem.
I wonder what the scrap value will be and how many battered old transit vans will be needed.
There are potential benefits. Even tax ones! So dead windmills could be used to create artificial reefs. Or a more cunning plan.. Use them as pillars and a lot of gabions to create artificial islands. There are some.. downsides, like these may end up still inside various nation's national waters, or EEZs. Plus the UN refuses to recognise artificial islands as sovereign nations. But this seems a perfect way to recycle useless windfarms, especially as they'd already have access to power and fibre cables. Add a couple of SMRs and some desalination, and make new land.
