The energy thread

[Jimbuna]

Here in the UK the energy price cap as set by Ofgem is currently £1928 but is due to be reduced to £1628 in April.

In the Netherlands, our energy price cap stopped only the poor get it

Yep, and they are incredibly inefficient and have no chance of being profitable.

They had not been optimized for civilian/commercial use, since they were not intended for that, but for a different purpose: to fit into a limited space, and that's it.



Anyway, the point regarding these new small reactors as designed and planned for commercial use now is that their existence in shiops and submarines proves the principle safety of these. That is a major point in Germany, because as you know as good as I do many Germans turn immediately hysteric over the " high!-risk!-TECHNOLOGY!!!-ATOMKRAFT...!!! "


Germans... Next.

It's been tried before several times and in several versions, and the results have always been the same. With existing technology small reactors are way too expensive both in terms of constructing and in terms of maintaining to make them viable for commercial use, and there's absolutely no technology on the horizon (not even in the hypothetical state) that is going to change anything about that.

Westinghouse seem to disagree. And eVinci is real. Note that the cooling is passive. It needs no active maintenance. 8 years long, then the whole reactor gets replaced, like a battery.

Well admittedly and thankfully I'm not poor but the price cap is applicable to everyone here in the UK.

We are getting close to harvest clean energy in neverending flow

On December 5, 2022, the system released 3.1 MegaJoules of fusion yield. Given that the laser pulse required 2.05 MegaJoules, the system produced more than 150 percent of the energy needed to start it.

As of yesterday my duel fuel payments have been reduced from £119 to £98 per month.

Well, friends and neighbors it's 2024. And things are going good for Planet Earth.The War in Ukraine is on target.We need to send more migrants to the battlefield after all when they came to our country, Who told them Freedom was free? Housing,Food,Clothing,Medical,Jobs and young women.You don't speak our language. Oh damn,Life is good. But you have a purpose.

All you have to do is fill the empty trenches on the frontline in Ukraine You don't have to speak any language, if you want to be free move forward. Look Democracy requires sacrifice.

So ,young migrant man if you don't have an IQ that we can use. And you want Freedom you will have to find your way through the Tombstones. And if you get back you will know what the price of Life is. Politicians sell Freedom,They and their families never sacrifice for it... Our Politicians are very smart. So I have a Question. For all immigrants why do you seek to live in the lands of the people you hate? Why don't you create a better land and country where you live? Are you afraid to die ? Or is it easier to walk over the backs and the graves of the people who have died to make their countries better than yours ?

Same here in Australia, the mere mention of the word Nuclear has everyone in panic mode, current Labour government has seen to that!! Makes my blood boil.
So now we have to stare at thousands of ugly wind turbines defacing the countryside!

Yes. As Bloomberg recently wrote: You have to question the wisdom of a country that closed perfectly good nuclear power stations. These once were seen as the global gold standard in reactor safety. But not good enough for hysteric Germans. Instead Germany now places a risky bet on hydrogen and LNG. The LNG bubble already has scared Germany to death two weeks ago when Biden suddenly stopped the - from the German side taken for granted - further widening and future expansion of LNG deliveries, due to concerns over the climate consequences of increased fracking and gas production.
And hydrogen? Have the Germans never cared to check out the physics and energy balance when you run the needed and highly energy-consuming processes to create hydrogen, make it transportable, and then reversing it att he destination? Its comparably problematic like the liquification of gas, and, if I recall correctly, as energy-intensive, if not more so, than the handling of LNG. I have linked the physics and chemistry behind it in some post some months ago. It kills the argument why one should want to go with hydrogen, especially when the hydrogen is not created right in the place where it is needed. The energy balance is a desaster. And nobody speaks about it. We are using more brown coal, and black coal too. We produce more CO2, because we wanted to take CO2-free nuclear out of the equation.



And the energy costs will grow steeply, and faster than before. Reasons is the taxes on energy and secondary costs added by the state and the grid comnoanies. Its absurd, at the international energy market prices drop - which means in Germany the private and industrial consumer has to pay more. - Last week I got mail form ym supplier, he is again raising the prices for electric power, 2.7 cents more per kWh.



Irrationality has gone pandemic in Germany. And its a hopeless fight against it. I think this country must crash down and get destroyed once again before the German people wake up. In this regard, impressive progress is being made. The industry for sure gives a vote of confidence on the German energy plans - it leaves the country in increasing speed and numbers. Last famous name reported on is Miele, a German top kitchen equipment producer, they will shift production from Germany to Poland. They are just the last in a long line. At the same time, it dawns on the German car makers that with their radical move to electric-only they will end with in a deluxe belly landing, while the Chinese ecar invasion has begun over here (which creates its own follow-on problems).



Vergesst Deutschland. Germany is done.

Electric cars over here are being scrapped because of the cost of battery manufacturing and disposal, now they are going to try hydrogen fueled cars!!

A lot cheaper and climate-friendly if you simply manufacture kangaroo saddles and ride around on the buggas

"The large rotating generators of the power plants are "grid-forming" machines; due to their large mass, they keep the frequency of 50 Hz constant in the range of seconds. For our colleagues at the BMWI and BNA, inertia is a physical property that ensures that power fluctuations are cushioned in a range in which the time for human intervention is too short. Wind turbines have only small masses and solar panels have no rotating parts at all, they are "grid-following" with their inverters; this means that they are connected to the grid of the "grid-forming machines" and do not have a stabilizing effect. Incidentally, gas-fired power plants tend to be "grid-following machines". The large power plant generators have also been responsible for maintaining the voltage in the grid through reactive power control.

"The electricity of tomorrow, which will be generated almost exclusively from renewable energies (RE), should not only be integrated into the electricity grid, but also be able to keep the grid stable at all times. However, renewable energy plants still lack the grid-forming properties that would enable them to ensure stable grid operation, especially in the event of a fault."

Sidenote: the number of microblackouts me and my parents and friends in other cities experienced over the past 10-15 years, has multiplied by factors. Before that timeframe, i did not know such things, not in the 70s, not in the 80s, not in the 90s. Reaction and adaptation times in the grid have been slowed down that much that now the existence of such malfunction events has become perceivable for the common man. We may talk about split seconds only - and yet, in this field of technology and physics-based events that is eternities.


What it means is that the wanted detoriation of the energy supply stability has become perceivable even for the layman. It will grow much worse.


Murphy's law is neither pessimistic nor optimistic, it simply states that everything that theoretically is possible to happen, sooner or later will happen if only you give it enough time. Well...
