Is it something in the air ? (Page 16/20)

This meme is a Non Sequitur. It's as if I said "the sky is blue" and someone came along and tried to debunk that by offering evidence that the sky is not chartreuse or fuchsia. It comes from the same place as the meme in the message that came before this message, and the meme in the message that came right before that message.

This is what happens when dumb people think of dumb reasons to call other people dumb (or #IDIOTS) and the memes that they create are picked up from Dumb Net or Dumb Chan or Dumb-a-gram and reposted here. I'm only posting it again myself, as a reminder of the discussion that ensues after some other forum member posted it as if it were something smart.

Even if you don't believe that there's any real climate emergency or climate urgency to reduce CO2 and other greenhouse gases, trying to validate this "ice cube" meme by posting it reveals your Inner Dumb because it doesn't address anything that climate scientists are actually saying. It misses its target because it starts with the ice cube already floating in the glass of water, and so, it only represents what climate scientists call "sea ice".

What about land ice? The experiment would have to start, not with the ice cube already floating in the glass of water, but with the ice cube still in the freezer, or in the hand of the experimenter, before that hand drops it into the glass of water. That would cause the water level in the glass to rise, proportionate to the mass of the water that's in the ice cube. Ergo, sea level rise. And that's only the phase transition. There's also the thermal expansion of seawater as it warms, also significant, but completely outside the scope of this meme.

Have a good dumb.

Have you ever seen a palm tree in a hurricane? They can survive because they flex and have a very large root ball to anchor them in the ground. I want to see a wind turbine do this.

As an admitted fanboy of floating offshore wind energy, I want to see that happen myself.

I don't know that the vertical tower or mast would have to bend like the trunks of those palm trees. Think back to that brief YouTube video that I just posted. They were testing a two-bladed turbine with an active system that keeps the blades oriented downwind. That's not the same as the large leaf fronds at the tops of those palm trees.

So far, the attitude of the investors that have bought into the Floating Offshore Wind Shot mantra by purchasing the offshore lease areas seems to be "Damn the hurricanes, full turbine speed ahead!"

Another possibility for storm and hurricane resistance are the vertical axis wind turbine designs. And even farther afield from the common three-bladed horizontal axis wind turbines that are currently state of the art, are the prototypes of "no blade" wind-powered generators that convert vibratory motion into electricity, and one design that I've seen that uses electrostatic potential to generate electricity from the saltwater spray in the air just above the surface of the ocean. A wind energy generator without any moving parts.

Storm and hurricane-resistant floating wind turbines extraordinaire

The "American Turbine," created by American Offshore Energy (AOE), is the first wind turbine of its kind without a central shaft. The lightweight fibreglass foundation of the vertical axis turbine makes it float like a hybrid between sailboat masts and bicycle wheels. The bearings and generator, two of the heaviest parts, are located on the outer rim, close to sea level, where surface speeds are high even at low revolutions per minute (RPM), doing away with the need for rolling bearings, gearboxes, and oil.

The AOE design also uses far less steel than a standard wind turbine and doesn't necessitate forgings, castings, conventional generators, or AC/DC converters while operating at sea.

Because of their reduced weight, these turbines might be produced and launched from locations that would be inaccessible to traditional floating turbines. They might be dragged and maintained by already operating boats that do not violate the Jones Act. The turbines could be manufactured in the U.S. without having to wait for components from other countries, since they could be constructed entirely of fabricated steel and fibreglass. The AOE CTO, Drew Devitt, said in a news release that this would aid manufacturers in deploying the turbines more rapidly and cheaply.

The absence of oil in the turbines makes it possible to submerge them in the eye of a cyclone and wait out the storm there. The cost of financing and insurance might be drastically reduced as a result. In the aftermath of a storm, the turbines might be elevated by releasing compressed air cylinders in the fibreglass floats from afar.

It would be easier to do routine maintenance at sea if service boats had their bearings and generator components on the deck. And if repair is required, the turbines may be disconnected and transported back to port in a day by Jones Act-compliant tugs already in service.

The advantages of the design include safeguards for vessels and marine wildlife. The vast vertical wing area is easily visible to birds and provides excellent horizontal radar reflection for seafaring purposes, but little vertical reflection for airborne navigation.

Time to go to the phones. Hello, Bismarck North Dakota. What's happening dude? Besides this Arctic Blast..?

#1) Remember the law of Conservation of Energy. A wind turbine converts wind to electricity, so downwind from a wind farm, there will be less wind.

#2) Hurricanes take heat from the tropics and dissipate it in more temperate regions. Hurricanes are driven by wind.

Wind turbines steal the wind from hurricanes and as a result, increase global warming.

Hell, if Greta can do it, I can do it.
