Just have a think, ICE cars EVs and power generation

It is somewhat of a difficult situation of course, because it relies on trust in some ways, but also being aware of fallacious reasoning. For example, I often see people argue that BECAUSE this is political, THEREFORE it is false. I’m sorry, that is just not true. It can be true while it is also being politicized.

(Remember when Zuma said he should not be prosecuted because of the political involvement?).

So in the end, the question remains: What is true? If it is true that the earth is on the brink of an environmental disaster, then your personal freedom be damned: You will switch to an EV or start walking! If it is entirely untrue, well then we should probably start looking for the cabal orchestrating all this (and some people claim to have already found them).

My personal view is that the matter is probably somewhere in the middle. We are indeed skewing our environment, we are making it hotter, we are affecting the weather. I think the earth has the ability to correct, like a finely tuned closed-control loop, it can recover… but if you know anything about closed control loop, the inputs required may be rather huge. So if you wonder about the huge swings, very wet months followed by dry ones, extreme weather, hurricanes, etc… it is telling us something. Besides, common sense tells you you cannot just continue to burn more stuff all of the time.

Herewith some practicalities regarding EV production (which isn’t included in the forecasts)

Not so good:
Evening Peak Feedback 28/09/2022, 18:36
Total Demand: 31 144MW
Loadshedding: 4 552MW
Interruptible Load Supply: 447MW
Virtual Power Station: 171MW
Eskom OCGT’s Utilised: 12
IPP OCGTs: 5
Renewable Gen: 870MW (Wind 869MW, CSP 1MW)

Available Generation Capacity: 28 226MW


Cr@p to say the least about a turnaround.

I think the thing that irritates me most about those holding negative opinions in this discussion… is that so far they’ve been the only ones who are consistently right. Credit where it is due. You guys irritate the dinges out of me mostly because you keep on being right… and that nonsense needs to stop!

:slight_smile:

Reporting on the news only. It gives me no joy whatsoever. I will be holding their feet to the fire, hence me switching off my grid connection.

Hoop dit help, Groetnis

I have become respectful of Eskom’s efforts, the guys that do their damnest for SA. Give credit where it is due … you made me think about them, doing their utmost.

Came across this, this morning, it is bigger than what we tend to look at:

Diesel shortage fuels Stage 4 power cuts
The power utility says this is due to delays in the supply of diesel.

A vessel carrying the fuel has not been able to berth in Mossel Bay due to rough seas.

Eskom says it will have to preserve low diesel levels at Gourikwa.

Delivery to Ankerlig will take some time as it is done by road tankers.

Stage 4 will therefore be maintained till diesel supply resumes to the two Open Cycle Gas Turbines.

Then I saw this:
Eskom CEO André de Ruyter was speaking at the Africa Renewables Investment Summit in Cape Town when he touched on the topic of Stage 15 load shedding. De Ruyter says he doesn’t want to know what that looks like.

If SA does not aggressively invest in renewable energy and relaxes its air quality standards, we may actually see Stage 15 load shedding.

Eskom’s models reportedly show that Stage 15 might need to be implemented if the above is not done. De Ruyter says that if this level of load shedding is implemented, it would cost 100 000 jobs.

What are the power utility’s options?
De Ruyter was speaking about Eskom’s existing coal power stations and how they do not meet minimum emission standards. Due to this, the embattled power utility is left with two options:

Spend about R300 billion to retrofit the power stations with equipment to clean their emissions or;
Decommission them.

The extremely high cost of this project would lead to increased electricity tariff hikes. This year, the utility applied for a massive 32% price increase. If the retrofitting option is completely off the table, Eskom is forced to shut down 16GW (gigawatt) of capacity immediately and 30GW by 2025.

The current load shedding schedules go up to Stage 8 …

Listening to Sarel, I get the impression these guys are in the minority at Eskom.

Then again, a few bad apples spoils the whole batch, so maybe you don’t even need a majority of bad guys…

But yes, I do get the feeling there is an internal battle between the good and the bad guys, the guys who want to fix things, and the guys who want to draw a salary for the least effort… or even more than just a salary in many cases.

Any problem can be turned around with enough time and money (those two are usually inversely proportional), and with the actual WILL to do it.

Firstly, when I was starting to consult to Eskom, that was old news 18 years ago. To be fair to Eskom, the CancER knew about that long before already. Seems to me they have vanishing memories.

But even worse, they wanted to just offset the emissions back then, not fix it:

So there is that…

DeRuter mentioned the Criminal syndicates. It’s part of the feeding trough network that keeps them powers in power. No wonder we on the Banking grey list as there is no accountability in SA. Nobody goes to jail here. Look at Zondo commission, estimates are R2.2Billion spent and nobody in jail and no curbing of anything… Don’t get me started. (No I have not even started yet)

Bugger …re. the air quality.

Seems the more De Ruyter calls a spade a shovel, the more “replacement” talks get pushed under the auspices of “the board cannot keep the grid on”.

Thing in my book, if De Ruyter is replaced, I’m not sure that is the point where one should stand up and say “ENOUGH ALREADY!!!”.

Mmm, not too sure what comes after that futile decision on my part. :smile:

This sort of thing is becoming more common now… almost weekly.

That’s right in the affordability bracket.

But, 1) it’s a 7-year old EV with an 8-year battery warranty, and 2) It is still a BMW, even if the mode of propulsion is different, I don’t expect it to be any different with the usual litany of small breakages (with the climate control blower resistor probably still being an issue, as it has been since 1997… :slight_smile: ).

Edit: Window regulators! What is it with European cars and window regulators? Nobody realises that plastic brackets with bicycle-type brake cable clipping in is going to break, mmmh? Nobody thinks that maybe we should just attach an electric motor to a scissor-mechanism like the Japs do, mmmh? The things I wonder (and complain?) about sometimes.

You got my attention!!! Wonder hoeveel range het hy nog in sy batterye?

Vriend van my het n 2022 een. Baie fun om te ry en baie spasie en rerig woelig op die pad.

There is a procedure for checking. You start with the VIN number, add up the last 5 digits. Write that number down.

Turn the car on, hold left bottom button (trip odometer) for 10 seconds until you get to a menu. Press button again to scroll down to “Unlock”, then hold again for a second to enter menu, then enter the number calculated earlier, push and hold again to enter, then go to battery capacity option, it shows what the BMS think is left in the battery.

From what I’ve seen, the BMS is conservative in its estimate, the battery is typically better than estimated.

Also note this is a 2015 model. I think it has the a 22kWh battery, when it was new it had a range of 120km. It should still have around 100km of that left if it was well treated.

Thanks @plonkster !!! Net genoeg vir werk toe en dan daar te charge en terug huis toe. hahahhaha :slight_smile:

The other thing to remember about the i3: It uses the AC compressor and refrigerant to actively cool the battery. That is a good thing, but it also means you cannot DIY it. You need the equipment to collect the refrigerant and regas it afterwards. You also cannot swap BMS modules on this without the BMW tooling to tell the computer(s) about what you’ve done.

Swapping modules on a Prius or even a Tesla is way easier than with this. This could turn into a huge money pit… or not… I don’t know :slight_smile:

They always want to make it difficult for us DIY :frowning:

Jip, Ek begin al hoe meer dink om daai turbo motor vir die beetle te stop en EV motor doen. Hier is al klaar n paar in SA.

Doen dit … use those new BMS’es you tempted me with! :rofl:

This is the cheapest one I’ve seen so far. There was one for 370k a week or so ago. Then 420k, 450k, and then above 500 after that. Above 500 you can get a very nice one, but that’s new Hilux money and I still have a mental block about that kind of thing.
