I think it is the crash of Tesla, its evaluation is based on being a silicon tech startup, not as an automobile company. So when the shares finally fall in line with other car manufacturers valuation, shit is going to hit the fan. And I think he knows he needs a government bailout and sanctions on foreign EVs specifically to price the competition out of the market. His entire empire is basically being propped up by the Tesla share price. He needs to go all in, it is survival mode for him right now

South Africa, you can read up on us if you want to learn about a country that really fucked up its energy supply, but that is a different story.

You do need a baseload, this is not something an argument of saying we do not really need a baseload can wish away, industries that run 24/7 like a smelting operation where if you cannot shutdown, or hospitals or traffic lights, there is a certain percentage of baseload that has to be generated.

Solar and wind are amazing and I really wish to see these systems play a major role in power generation, but you say the nuclear and coal plants are very inflexible. I do not know who this guy is but Nuclear and coal can very easily ramp up their power generation, both these are basically steam engines, both nuclear and coal can very quickly heat up and generate a lot more steam that powers generators, like an car engine but more accurately a steam train that you give more power to go faster. Solar and wind cannot ramp up on their own, cannot ask the wind to blow harder or the sun to shine brighter suddenly when the system requires it, they need costly backup systems like methane peaker plants or energy storage, be it batteries, pumped hydro, hydrogen electrolysis the list goes on. These things added to solar and wind plants are usually not allocated to the cost of generation, a total cost of generation including these additional backup systems are a better indicator of solar and wind systems cost.

Now what about waste. I agree coal is messy and is causing global warming and needs to be phased out. But nuclear waste is a solved problem, it has been for decades, the spent fuel is usually stored deep underground where it will never interact with the world again. Solar on the other hand, if it costs about $20-$30 to recycle a panel but like $1-$3 to send it to a waste dumps, what do you think will happen to the solar panels. https://hbr.org/2021/06/the-dark-side-of-solar-power Harvard business did an article about how solar recycling has really been a point of weakness, where nuclear we have set guidelines on how to environmentally and safely dispose of nuclear waste currently. I am willing to bet you the environmental impact from pollution from nuclear, including all the disasters will be negligible compared to the waste impact from solar panels and batteries currently.

So my point is not to dismiss solar or wind, really where wind and sunshine are naturally plentiful it will be a waste not to harvest these resources, just like where geothermal resources are available it will be wasteful not to utilise it.

But nuclear, even with its high initial capital cost and long build time, still does provide energy cheaply and will last for a lot longer than solar panels and wind turbines, nuclear can be easily and quickly ramped up or down depending on the load required.

Well one easy one, in my country it is that nuclear plants need to emit zero radiation from their core, like nothing. This is incredibly expensive to achieve, a more sensible value would have been similar or less than normal background radiation.

Nuclear has a lot of advantages that are really low hanging fruit of producing safe clean energy that is perfect for a grids baseload.

I love Mint 22 so far, it really has matured where my home computer is running Mint is more stable than my work computer running Windows 11, luckily my company uses CrowdStrike so nothing to worry there.

But really I now recommend Mint to my non tech savvy friends and family, as a person who uses Linux should! But joking aside took my sister’s old laptop running Windows 7, slapped a SSD and upped the ram to 8 GB into it with Mint and she has been happy

Microsoft launcher on my Nokia T20 3GB version and on that little memory the tablet had regular crashes. Went back to stock no fine

So only energy losses in theory

Yes, basically. Enegy is used on H2O gets split and turned into H2 and O2, the H2 then in the fuel cell gets to react again with O2 to produce energy, less than what was used to split it, why it is inefficient, and now stable H20

Of course not, hydrogen is pathetic compared to batteries and similar stored mass energy solutions, but hydrogen does have its place, the future should be a mixture of different solutions because many methods have their advantages and disadvantages, but having a mixture means we can apply the best solution to the viable problems. Let’s take transportation, you have a truck that earns money by travelling. If we want to transition away from fossil fuel, hydrogen makes sense over batteries that takes an hour to multiple hours to charge and the weight of the batteries reduce the overall payload of the truck.

Hydrogen reaction to oxygen in a fuel cell turns it back into water

This will hopefully lead to storage methods, maybe exportable ones like hydrogen

I lost it at Martha

Agree where is coal, but it is hard to track since most of these have a set value and quantity at that time and is usually sold and usually tracked at which amounts, where coal is a different beast, you have different types of coal, like peat, lignite, bituminous and anthracite, then there is even in the same type different grades and quantity, like bituminous coal you will look at the water content, the ash content, amount of macerials… All of these affect their price. Then some coal is mined and consumed at source, usually powerplants are build right by coalfields, to minimise transportation costs, and the mine might be owned by the powerplant, or with a private contract where the price and quantity would not be disclosed to the public.

But if you look at USA, China, India and Indonesia, I think, so my very biased outlook, their combined coal mining, not only in $ but also in Tonnes, will make oil look like a small footnote.

Not an American but if you should have and every country should have a minimum age, like 21 because of mental and physical maturity, and a maximum age like 75, because of the risk of possible stamina and mental decline.

So cool you work on submarines that is extremely cool, I am in a way different industry, mining. Jeez I wished we had your safety record of only one lost submarine. Our industry has gone through a couple of mines in the same period.

But wow, how does the safety of submarines compare to other industries, granted outside of war times, like compared to trains or even other seafaring vessels

Ok it probably was prepreg now that I think back, but I saw the application video where the just rolled it on no vaccume bags to remove any voids or cavities

Usually these program’s rules seem very tedious and restrictive and I can easily see one person looking at this and think they are in place to stifle innovation and keep the little guy out.

I remember how he said to not have regulatory approval because of of this or that, but why not get a regulatory expert to have a look, might not approve your vessel but might show clearly missed safety critical blindspots.

But these rules exist for a reason, they where usually written in blood, it’s how I know this incident added rules to your SUBSAFE program.

I think this was the original sin, the root cause. One man’s vanity and arrogance, which made him blind to his own shortcomings. He build something great, let us not lie, but we can clearly see in hindsight the obvious truth. Well if what people that know way more than I do are right, the vessel imploded quicker than the neurons in your brain, so it must’ve been an quick painless death

There’s how you spell the word

I have worked in underground mines, and this scenario of being bolted inside gives me way more cluster phobia than any experience I have had

I have no issues with the controller either think it was a great addition, were I had a gripe is that it was the only way to operate the vessel, so not an addition but the sum total of controls.

Like if you were bolted into a vehicle, with no way to interact with the outside except a tiny window and only a game controller, it is a lovely piece of efficient engineering and does everything you need, but if this controller maybe gets damaged for example it’s cable was unfortunately pinched off by someone’s shoe. When you realise at a 1000m the closest thing to a god is that controller working and taking you safely back to surface in time or being stuck and hoping the guy who got you into the mess, that his, only other plan the dissolvable ropes on the weights actually work and you get to surface and get found and unsealed before air runs out.
