An alternative to Diesel: the Baureihe 563

More and more of these trains have appeared in the Offenburg area recently. Technically, I could be talking about both of the trains above because I'd never seen a Baureihe 218 locomotive (right) before, though over 400 were built in the 70s, but I am talking about the train on the left: the Baureihe 563.

5 is an unusual first digit for a German train type. Locomotives start with a 1 or a 2, for electric and Diesel power respectively, while passenger-carrying multiple units start with a 4 or a 6, again for electric and Diesel power respectively. Evidently, as seen above, these trains can run on non-electrified lines, but they are not Diesel multiple units - they are battery-electric multiple units.

Part of the Siemens Mireo family, the Mireo Plus B can run on electric power either from the overhead cable, or from the onboard batteries. The manufacturer states that the train can run between 80 and 120 km on battery power before needing a recharge from overhead cable, typically at a terminal station. This makes this train ideal for relatively short runs, such as those seen around Offenburg, the central station of the Ortenau area. As such, they are becoming more common, running local services for regional operator SWEG, indifferently on non-electrified lines like the one to Oberkirch, or electrified lines such as the picturesque Schwarzwaldbahn.

I know that Japan and the UK (link to Jago Hazzard's review of the GWR Class 230 and a quick overview of the BEMU topic) have also recently (re)introduced BEMUs. France hasn't really got on-board with this yet, as far as I know. Instead, they have built lots of bi-mode trains (mentioned at the end of the post), which have electric motors which can be powered by overhead cables or by an on-board Diesel engine.

A well written explanation involving Lithium Ion Batteries. 👇

Understanding Thermal Runaway in Lithium Ion Battery Fires. Thermal Runaway Explained:

Thermal runaway is a chain reaction within a lithium-ion battery that can lead to catastrophic failure, resulting in fires or explosions. Here’s a step-by-step breakdown of what happens during thermal runaway:

1. Initial Trigger: Thermal runaway can be initiated by several factors, such as physical damage (e.g., puncturing or crushing), overcharging, manufacturing defects, or exposure to extreme heat.

2. Internal Heating: Once triggered, a part of the battery starts to overheat. This can be due to an internal short circuit or a chemical reaction within the battery.

3. Chain Reaction: The heat generated from the initial trigger increases the temperature inside the battery. This heat can cause other parts of the battery to react, generating even more heat.

4. Rapid Temperature Rise: As the temperature rises, the electrolyte inside the battery—a flammable liquid—starts to vaporize and decompose, producing gases. This further increases the internal pressure and temperature.

5. Gas Release and Ignition: The increasing pressure can cause the battery casing to rupture, releasing flammable gases. These gases can then ignite, leading to a fire or explosion.

6. Propagation: If the battery is part of a larger battery pack, the heat and flames can spread to adjacent cells, causing them to undergo thermal runaway as well. This can result in a large, intense fire that is difficult to control.

Key Points: - Difficult to Extinguish: Thermal runaway fires require massive amounts of water to cool the batteries and stop the chain reaction. Traditional fire extinguishers are often ineffective.

- Toxic Gases: Burning lithium-ion batteries release toxic gases such as hydrogen fluoride, which can be harmful if inhaled.

- Reignition Risk: Even after the fire appears to be extinguished, there is a risk of reignition. The battery cells can remain hot and unstable for hours or even days.

Safety Measures:

- Distance: Establishing safety distances to keep people away from the danger zone.

- Continuous Monitoring: Using thermal imaging to monitor for any signs of reignition.

- Specialized Response: Firefighters need to use specialized techniques and equipment to handle lithium-ion battery fires safely.

Understanding thermal runaway helps in appreciating the complexity and danger of lithium-ion battery fires, highlighting the importance of safety precautions and effective response strategies. 🤔

"A net-zero power system is closer than we think.

New research, published by RMI, indicates that an exponential surge in renewable energy deployment is outpacing the International Energy Agency’s most ambitious net-zero predictions for 2030. 

That’s right: Surging solar, wind, and battery capacity is now in-line with net-zero scenarios. 

“For the first time, we can, with hand on heart, say that we are potentially on the path to net zero,” Kingsmill Bond, Senior Principal at RMI, said. “We need to make sure that we continue to drive change, but there is a path and we are on it.”

And that’s really good news.

Exponential growth in renewable energy has put the global electricity system at a tipping point. What was once seen as a wildly daunting task — transitioning away from fossil fuels — is now happening at a faster pace every year. 

Based on this new research, conducted in partnership with the Bezos Earth Fund, RMI projects that solar and wind will supply over a third of all global electricity by 2030, up from about 12% today, which would surpass recent calls for a tripling of total renewable energy capacity by the end of the decade. 

Global progress in the renewable energy sector

China and Europe have been leading the way in clean energy generation, but the deployment of renewable energy has also been widely distributed across the Middle East and Africa. 

Research from Systems Change Lab shows that eight countries (Uruguay, Denmark, Lithuania, Namibia, Netherlands, Palestine, Jordan, and Chile) have already grown solar and wind power faster than what is needed to limit global warming to 1.5°C, proving that a swift switch to renewable energy is not only feasible — it’s entirely achievable. 

In order to make that switch, globally, wind and solar need to grow from 12% to 41% by 2030. Denmark, Uruguay, and Lithuania have already achieved that increase in the span of eight years.

Meanwhile, Namibia, the Netherlands, Palestine, Jordan, and Chile have grown solar and wind energy at sufficient rates for five years...

The economic impact of climate progress

Not only is this an exciting and unprecedented development for the health of the environment, but this rapid transition to clean energy includes widespread benefits, like jobs growth, more secure supply chains, and reductions in energy price inflation. 

This progress spans both developing and developed countries, all driven to accelerate renewables for a number of different reasons: adopting smart and effective policies, maintaining political commitments, lowering the costs of renewable energy, and improving energy security. 

And with exponential growth of clean energy means sharp declines in prices. This puts fossil fuels at a higher, uncompetitive cost — both financially and figuratively. 

RMI suggests that solar energy is already the cheapest form of electricity in history — and will likely halve in price by 2030, falling as low as $20/MWh in the coming years. This follows previous trends: solar and battery costs have declined 80% between 2012 and 2022, and offshore wind costs are down 73%."

The main galactic power players, post-war:

First of all, the krogan. At the very least, the krogan must get a seat in the council. If a named/old character has to be the one to hold it, it should be Bakara. Wrex should rule a unified Tuchanka. Their help was instrumental in holding Palaven, and as a consequence, humanity and the turians. I can see all three peoples become closer allies. Tension would remain, especially between the turians and the krogan, rightfully so. However, I can see the Hierarchy, under Victus, finally start to pay reparations for the genophage.

An initial offer is made to get turian workers to Tuchanka, to help physically rebuild the planet's main cities. This is completely vetoed by the krogan leadership, obviously. These guys were doing secret operations like a year ago to disable a gigantic bomb they had buried in their planet to destroy them. They agree on raw materials + monetary compensation until krogan population reaches pre-genophage and post-industrialization, but pre-expansion numbers. A surviving Shepard that keeps working as a Spectre would totally mediate the negotiations as an impartial observer. It is also yet another show of cooperation between all three peoples.

Now, the asari... would they get any sort of penalty for hiding the Athame beacon? Would it all get swept under the rug due to corruption? Would it be purposefuly "forgiven" due to the galaxy-wide destruction? Let's be real - if they had revealed the secret as soon as the Alliance and its allies started building the Crucible, they would've defeated the reapers much sooner. Hell, maybe Thessia would've been spared - it's attacked after the Crucible plans are found on Mars, with enough time to spare to give Alliance officials (including one very annoyed human spectre) the information.

Even if they didn't know that the beacon held information on how to destroy the reapers, it was known that a weapon of prothean origin was being built, and they had information that came straight from the protheans. If the matriarchs had any common sense, they'd start offering asari help to rebuild say...the Citadel. The keepers were basically reaper tech, right? So it stands to reason that they would've died with them, too. Now, if the others had any common sense they would refuse the generous offer and get their hands on it first (when both humans and turians call dibs, Done-With-Your-Shit Shepard says it should be the asari, under strict council supervision).

Salarians! They did not withhold crucial information, but they actively tried to sabotage the biggest war alliance by trying to ruin the cure for the genophage, and withholding support when they didn't get their way. To save face, the STG could try to make it seem like it was the Dalatrass acting alone, have her replaced, and profusely apologize. They are not formally penalized, but their political influence is definitely diminished. Again, the krogan are now among the most influential species, and the humans and the turians didn't get any help from the salarians, either. The asari chose to stay impartial in that mess, and look how it turned out for them. As such, they'll both need to keep a low profile until things have significantly cooled down.

The quarians would have no interest in joining, I believe. They'll be high on the thrill of getting their planet back. They'll need to completely reorganize their entire society, so galaxy-wide politics would take a backseat for a while. They are used to self-sufficiency and ostatrization for everyone else, so I can't see them being too keen on them, too.

Unfortunately, I don't think the "secondary" species/worlds would get much more influence or power. Some of them, like the volus and the elcor contributed a non-insignificant ammout to the war effort. However, allowing the volus into the council would be a conflict of interest: they are a client race to the turians, so unless they became completely independent for a long while, they wouldn't get that seat. Since elcor made a similar contribution, it would be unfair if they got it and the volus didn't, so no more seats for anyone. The drell don't even have their own planet, and the overall contribution from them and the hanar was not significant enough to change much of their status. Of course, all of these are excuses. The big power players are just not keen on sharing, just like before. After all, politicians will be politicians, and a sense of unity only goes so far.
