Rovers as opposed to humans. Humans need food, a pressurized, temperated air environment, a discharge for their excrements, a higher level of safety and return mechanisms, much stronger radiation protection…

So a big event without any practical relevance because there is more cheaper, reliable and safer alternatives available?

There is only so much mentoring can do though. You can have the best math prof. You still need to put in the exercise to solve your differential equations to get good at it.

My impression is that people will be eager to tell in the comments that a news source is bad or biased, or that the specific article is misinformation.

At the end of the day, if you just trust some rank value that someone tossed in, w.o. knowing who is behind it exactly and how they reached that conclusion, it can be an easy source for disinformation.

Also some news outlets are providing reliable coverage on some issues, while being biased on others. Often they just repeat texts from Reuters, AP or other agencies. So any single value rating can warn you that the same message is “biased” in one case and in another case it cheers it on as “reliable”.

In other words: You can keep jumping out of the window in different ways, trying to find a way for humans to fly w.o. mechanical help, or you can just accept taking the stairs.

Seriously, my first thought was looking forward to the ADL explaining why smiling Hitler denying the Holocaust is not antisemitic since it isnt against Israel or something.

Well the only way to change that is to engage with those communities and provide content. Ofc. community building isnt easy.

I am sorry, but your ideas about how these things work are ignoring a lot of issues.

First of all you have significant losses in the distribution grid. This is minimized the higher your voltage is, which is why longer range grids run on 110 kV and more. Then you have an intermediate level, typically 20 kV. Finally you get your local distribution with 220/230V. Also “current flowing the other way” does not exist in AC, because the “direction” changes 50x per second.

Then you only have a limited transportation capacity, so moving a lot of electricity from a central plant of course costs a lot of investment and maintenance. The idea that “Transporting it is for all intents and purposes free” is completely out of touch with the reality of the electrical grid.

But it gets worse. The more producers and consumers you have, the more you will need to balance fluctuations in production and consumption. This is why traditional grids were built around having a high baseload, with incentivizing high demand industries to connect, stabilizing demand. For renewables this is completely different, because renewabls will fluctuate. So the more energy you run through the centralized grid, the more short and medium term storages you will need to provide and the more investment and running costs you will have.

You mention this with there being too much production on the local grid and then in another place also needing to react to this. This is not a problem exclusive to local grids. It is a problem for any level of the grid with integrating renewables. Note how the article also mentions the limit of 800W without requiring a permit.

Finally in the long term we need to make the demand more flexible to production. So if the sun shines and the wind blows, household appliances should run, the fridge should cool a bit stronger, and the water heater heats up for the evening shower… Having a responsive demand with millions of agents can easily lead to overshooting, so that the demand spikes up far beyond supply, because every consumer reacts at the same time and it doesn’t temper out.

This problem is much smaller, if every household can directly see their own production and consumption and already limit how much excess goes into, or is demanded.

So microgeneration is part of the solution and not a problem like you make it out to be.

Hard to justify costs? The article quotes 6 years of amortization. I know numbers around 8-10 years in Germany.

Show me any consumer investment, that gives such a good ROI.

Balcony solar is not unsafe though. At least it is not more unsafe than say putting a plant pot on your balcony, or operating power appliances like fridges, stoves, washing machines…

Why are you cooking for yourself at home? It would be more efficient, if you organize a shared kitchen in the house and each evening a different party cooks for everyone in the house.

Upon being awarded the prize of A$10,000 (equivalent to $36,011 in 2022), Young said that he did not know there was a prize and that he felt bad accepting it, as each of the other five runners who finished had worked as hard as he did—so he gave A$3,000 to 41-year-old Joe Record and A$4,000 to the other runners, keeping only A$3,000 for himself.[2] Despite attempting the event again in later years, Young was unable to repeat this performance or claim victory again.[8]

Turns out regulations are good for businesses.

I wonder how they communicated GUI colors then.
