Bears are protected animals on Slovakia, so they got overpopulated and the number of incidents with humans went up. So some ppl want to shoot them now.

Well , Here in America we are overpopulated, So we shoot people,animals and anything that our government that rule.Tell us that need to be shot.Don't believe that .Oh have you seen any animals on the streets of any Major city in America ? No our immigrant's do the killing of local animals and turn them into food.

Well , Here in America we are overpopulated, So we shoot people,animals and anything that our Socialist gangsters that rule.Tell us that need to be shot.Don't believe that .Oh have you seen any animals on the streets of any city in America ? anything worth barbecuing is on the grill.

well, it reminds me that nutrias around rivers are often overpopulated here, but it is not allowed to hunt them.
It is strange that even homeless guys are not hunting them for food.
Just Ukrainian migrants are poaching fish here.

Nutrias have become an ever growing problem in Germany, since they are eroding dams, bridge fundaments, dykes. They are being hunted. I see them in the Rieselfelder here around my corners. Usually very pleasurable and peaceful animals, and not more dangerous rergarding zoonotic infections like other wildlife, and certainly not as infectous as rats and mice - but they live in wet environments where they can fetch up quite some bugs. They get along very peacefully with close animals, melt peacefully into huge flocks of ground-nesting water birds or a huge flocks of geese or seagulls, nobody is fleeing from them or avoiding. I saw them almost rubbig their fur against feathers, so to speak.

But you dont wont to get bitten by them. That are some formidable orange teeth that they have, and they are big and real. :03:

Their meat can be eaten, but you need a vet testing it first, of course. Many years ago I heard that in the Netherlands they even had a few restaurants that serve them. Or served? Its long time ago.

They are no rats, although they look like huge rats. They are also no bibers, although many think they are. They are a separate species, but are genetically very closely related to guinea pigs. I see and observe them quite often, even had them close to me, but I watch out to not have them closer than 2-3m minimum, then they usually do not feel threatened and just peacefully munch on, ignoring me completely.

We need to keep them short due to their erosive effect on infrastructure, but I regret that we need to go after them. I like them.

@Skybird - yes, nutrias look a bit like a giant hamsters or guinea pigs with orange teeth. :)
That is probably why people think that nutrias are cute and why they feed them. Plus they are not afraid of human like birds or other animals living around rivers.

They are also on the menu in Belgium. In Dutch polder areas and near rivers, beaver rats are a threat to dykes, which are weakened by the burrows the beaver rat digs in the dyke. Therefore, it is actively caught in traps by employees of the water authorities or municipalities.

All you have to do is check the different energy densities of hydrogen and LNG to see the insurmountable physical problem.

And the root problem causes a long, a very long rat tail of follow-on-problems. Technical problems. Logistical problems. Energy transfer rate problems. Economic problems. Ship building capacity problems. Most of them have no practical solution imaginable, not under realistic assessment.

But it all starts with the much lower energy density of hydrogene. There is no way around this physical fact.

--------------------------------
Water is to hydrogen what carbon dioxide is to carbon. Both are combustion products. Water could also be called hydrogen oxide. Combustion products are generally not good sources of energy, yet hydroelectric power plants have existed for a long time. Let's take a look; it will help us better understand "hydrogen technology."

The water in a mountain reservoir has "potential" energy, meaning it could do work if only allowed to. To do this, it must flow downhill to drive a mill wheel or a turbine. The source of this drive is the Earth's gravity. The farther away from the Earth's center, the more potential energy it imparts to a mass.

So for a hydroelectric power plant, we need more than just water; we also need mountains. If Holland had more mountains, it would be a hydropower paradise, because there would be plenty of water.

From Holland, we take a detour to a hydrogen atom. It consists of a nucleus—which we won't be concerned with here—and an electron, which, thanks to its electrical attraction, stays in the vicinity of the nucleus, as close to it as possible.

A long time ago, hydrogen atoms discovered that when they pair up and form a two-membered household, they can then move even closer to their nuclei. This reduces their potential energy. Just as water occupies the lowest possible energy level to which it has access, so do atoms.

So if you go looking for individual hydrogen atoms, good luck. You'll only find molecules called H2.

But even those aren't easy to find, because they tend to add an oxygen atom to their two-membered household. This then lowers the potential energy of everyone involved even further. Voila: This "ménage à trois" is the water molecule H2O.

You don't have to look far for oxygen; it's in the air. So, if we were to mix H2 and O2 molecules, they would love nothing more than to join forces. To do that, however, they would first have to leave their own little two-person households, and for that, they need a nudge, but then things get going.

The nudge could be a spark; there's a huge bang, and the H2/O2 mixture becomes water. This gas mixture is aptly called oxyhydrogen ["Knallgas" - gas with a bang - in the orginal text]. Incidentally, an explosion of this kind occurred at the damaged Fukushima nuclear power plant. Oxyhydrogen formed in a cooling pool and blew off the roof of the building. That had nothing to do with nuclear energy; it could just as easily have happened in a chemical factory.

Instead of letting the electrons' transition energy to the lower level dissipate in an explosion, you can politely ask them to run through a wire and do useful work in the process. It's like when you don't just let the water trickle down a mountain, but instead channel it through pipes and drive a turbine.

The height of the energy levels in atoms and molecules is measured in volts, by the way; we're dealing with electric fields here. We're talking about a few volts at most.

We can harvest the aforementioned energy gain when electrons transition to a lower level in a suitable device called a fuel cell. This is where the controlled reaction of H2 with O2 takes place, producing a voltage of approximately 0.7 volts. A combination of many such cells could then provide enough electricity to power a machine, such as a car. And obviously, the whole thing produces nothing but pure water. So we've found the perfect, clean energy source—hallelujah.

The fuel cell, by the way, was invented 200 years ago. Why hasn't the H2 revolution happened long ago?

There's still one small problem: Where are we supposed to get the hydrogen from? We don't have it any more than the Dutch have mountains. But wait! We can get it from the water. And there's plenty of it. We just need to reverse the process in our fuel cell, and then we could turn water back into hydrogen and oxygen!

This is also a proven process called electrolysis. All we have to do is offer the electrons 1.2 volts, and they will leave the water molecule.

As an attentive reader, you might now object that this is a bad deal: We put 1.2 volts into the electrolysis and only get 0.7 volts back in the fuel cell.

But that's exactly how it is. In this game, we're dealing with three different energy levels: At the very top, at 1.2 volts, are the individual hydrogen atoms; at the middle level, at 0.7 volts, are the hydrogen molecules; and hydrogen is at level zero.

Electrolysis starts from the very bottom to the very top. Then the hydrogen atoms spontaneously combine to form H2. In the fuel cell, however, we only get back the 0.7 volt difference from the middle to the bottom.

What's the point of that? You put electricity in at the front, and only half comes out at the back. Who would want something like that? And in fact, you only get a third back, because in addition to physics, the technical implementation also has its friction losses.

The architects of our energy transition still want something like that. While wind and photovoltaics don't always produce the electricity that's needed, they provide too much at other times of good weather. This surplus could be used to produce hydrogen, which is then stored and converted back into electricity when the wind and sun are weak.

But that's not all. We could equip our cars across the board with hydrogen tanks and fuel cells and run them electrically – completely carbon-free. And we could also convert aviation to hydrogen – despite the bad experience with the Hindenburg.

In principle, hydrogen is the desperately sought-after energy storage medium, albeit with catastrophically poor efficiency. For the model to be technically viable, the surplus of alternative energy during peak periods – averaged over weeks and months – would have to be three times as high as the shortage during lull periods.

We're far from that today. But is it impossible? No – but it would be economic suicide, because this approach would make electricity even more expensive than it already is. Wind and solar would have to be aggressively expanded to increase the surplus during sunny periods and reduce the shortage during lull periods. Will that happen?

I have no doubt. This will be the final act in the drama known as the energy transition, a tragedy characterized by willful blindness to economic realities, driven by ideology and dogmatism, devoid of logic and professionalism. And with this final curtain, the success story of German industry will end – "Not with a bang, but with a whimper."

For insiders, however, there is still a very lucrative "win-win" deal: Germany will finally be completely covered with wind and solar power, right down to the last corner. This will generate additional billions in an established business area between well-established partners. At the same time, the new hydrogen industry will be built, which will be of similarly gigantic proportions ("Even the German government is thinking big on this topic"). This will then become a second, new gold mine, in which the taxpayers' money of defenseless citizens will be mined with large excavators.

White hydrogen, natural hydrogen, also called ‘geological hydrogen’ or ‘gold hydrogen’, is hydrogen found in its purest form in the ground. According to the U.S. Geological Survey, more than 3 trillion tonnes of natural hydrogen is thought to be available underground worldwide. ‘Most of this may be inaccessible, but the mining of only a limited portion may already be sufficient to meet the expected demand for hydrogen,’ said lead researcher Geoffrey Ellis. The big advantage of white hydrogen is that no energy is needed for its production. According to the Financial Times, there are 5 trillion tons of natural hydrogen resources worldwide. Most of this hydrogen is likely dispersed too widely to be economically recoverable, but the U.S. Geological Survey has reported that even a fractional recovery could meet global demand for hundreds of years. A discovery in Russia in 2008 suggests the possibility of extracting native hydrogen in geological environments. Resources have been identified in France, Mali, the United States, and approximately a dozen other countries. In 2023 Pironon and de Donato announced the discovery of a deposit they estimated to be some 46 million to 260 million metric tons (several years worth of 2020s production). In 2024, a natural deposit of helium and hydrogen was discovered in Rukwa, Tanzania, as well as in Bulqizë, Albania.

But you can also use ammonia as fuel for industry, shiping, for example the Australian ship The Green Pioneer is the first ship in the world that can run on ammonia. Ammonia is burned in the combustion engine. Substances are released, but they are purified in a scrubber. So those stay on board, they don't go into the air. By now, we know very well how to deal with ammonia. We can make it safe, there is an enormous amount of experience in the industry, but also in transporting ammonia. Another successful test took place on 12 May for bunkering ammonia between two ships, at an APM terminal on the Second Maasvlakte that has not yet been commissioned. There, 800 m³ of liquid ammonia went from one test ship to the other in 2.5 hours.
