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

Some of us like to tinker. We really get satisfaction of having a weird niche filled and even if it comes at the cost of stability and other issues. Heck my Custom Roms used to be more up to date with security updates than phones that were older than one year.

I could use kernels that undervolts my processor to give me better battery life. It allowed features that even 5 years ago were on the custom ROM scene still very absent from modern phones.

But the most important part for me was learning, discovering. If I tried a new ROM I would spend hours going through certain roms settings. If there is a glitch, learn how to diagnose and try to fix it, or learn to send a logcat to the developer.

It was like a fun hobby. I learned how to fix some of my old phones, like screen replacement, and learned how to cure uv reactive glue. So many other things and I was just a noob.

But it gave freedom. I understand iPhone and the other high brands are easy to use, have gimmicky features and all, but dammit I have freedom to have my weird niche phone, with multiple breaking features and I loved it because it just worked.

If Google truly did hold security as its main concern, it would have opened the play Store, yet we know now they only wish to protect their monopoly

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.

Icarus was insane. From an amateur cyclist trying to up his game that leads him on a journey of discovery into the world of performance enhancing drugs and escalates to literally the highest echelons of the sporting world leading to global ramifications, maybe a war.

Also Ai is your friend in interpreting and summarising the paper, but be careful it isn't perfect

I would add to this libmaps, great resource to put the title of your document and it maps the paper, from where it is cited to whom cites the paper that has more up to date research. Then if the paper isn't available use my friend above's method to access the papers

Are hot air balloon not like super safe, last accident I think was a guy that made his own DIY hot air balloon but before that it has been relatively safe. I think America has only seen like less than 800 deaths total.

If the comic put in zeppelins...

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
