Actually offshore wind is cheaper than diesel. Diesel internal combustion generators is just about the most expensive way to produce electricity, by a long shot.

Not on a small off-grid community. I think you'll find offshore wind farms cost millions, while you can buy a diesel for $1000. Stop making irrelevant comparisons that ignore scale. A diesel generator on the grid is as silly as an offshore wind-farm for a small isolated community. Nobody is replacing diesels with wind, though they might experiment with supplementing it.

My point was that this project is funded by selling power to the grid, and selling it to the island is just a PR point.

I think you'll find that most "eco-friendly" headlines ...

Nothing to do with "eco". Most headlines are BS. Yes, they are selling it to the locals as cheap power, to try and avoid NIMBY-ism.

Real economics is harder to sell. Coal power should have massive taxes to cover externalities - the health and greenhouse effects of emissions. If they had to pay a fair price for all the garbage they dump into the atmosphere, alternatives like wind and nuclear would start looking very affordable.

Headline is misleading. It is not the turbines, but the link to the national grid that is making power cheaper for the island.
Until now, they depended on small local diesel generators.

You can bet that the 30MW wind plant is a lot more expensive than the diesel generators were.
I'd be interested to know the economics of the plant, but supplying cheaper power to the island will be an utterly trivial component.

It doesn't matter if you have a whole leg missing - you won't even be much slower. Cycling is more limited by heart-lung function, not leg muscle mass. You just need toe-straps or clip-in shoes. Sorry, ... shoe.

Are you denser than a 12 billion solar mass black hole?

Actually, he is. Unlike regular black holes resulting from supernova collapse, a super-massive black hole is not very dense.
e.g. a one-billion solar-mass (2x10 to 39kg) hole would give a density of 200kg/m3 - less than that of cork!

Some have proposed that we may living inside an even bigger black hole.

Where did you get that Idea? 100 years ago? Africa actually has quite a low rate of breastfeeding now, with some exceptions like Malawi.
Numbers depend on the age, and whether you mean exclusive.

U-235 has a much shorter half-life, hence a much higher radioactivity.

Not really. It is still 700 million years for U235. A few times almost no radiation is still almost nothing.
A few kilos of uranium would be no worse than sleeping over a pile of bananas.

Its things like radium and plutonium, that are orders of magnitude more unstable, where you need to start considering the hazard.

From Wikipedia, the free encyclopedia
Doxing (from dox, abbreviation of documents),[1] or doxxing,[2][3] is the Internet-based practice of researching and broadcasting personally identifiable information about an individual.[3][4][5][6] The methods employed to acquire this information include searching publicly available databases and social media websites (like Facebook), hacking, and social engineering. It is closely related to cyber-vigilantism, hacktivism and cyber-bullying.

Doxing may be carried out to aid law enforcement, business analysis, extortion, coercion, harassment, public shaming and other forms of vigilante justice.[7][8]

Some people have a great ambition: to build something that will last, at least until they've finished building it.
