It does sound like bullshit too bad it’s true

>As long as you have some minimum number of people (specialized skills) and enough manufacturing machinery, this won't happen.
You'd need quite a large number of people with many specialties, I think. The idea of a small self-contained system is more of the problem. You also can't forget about materials (how are you getting them?). Much of our technology relies heavily on the global economy, and there has been no effort put in to try to make these self-contained systems even on a nation-sized basis (except maybe North Korea, and even they rely on the global economy despite every desire not to).
We don't necessarily have a good reason to believe we can for sure make a smaller self-contained system. It may be possible, but it isn't a given, an. it's certainly not an easy problem.

While the purists might want no engine, that is kind of unrealistic given the need for a ship like this to maneuver into and out of busy modern ports. I suspect getting becalmed in the middle of a busy shipping channel would not be looked upon favorably by the port authorities. Either hire a tug, or start you own engine (which is difficult if you don't have one) and get out of that container ships way.

I hope not as well, but the engineering of it has never mattered much to either group. I guess Im just bitter at all the obstructionism.

Tesla is not interested in the mining business... they want processed lithium...

I'd hope not. Grounded Lithium plans on using a process called Direct Lithium Extraction (DLE) which has potential to offer an ESG-friendly source of lithium. DLE technology may allow for lithium extraction without the need for large-scale mining (per typical hard-rock operations) nor large evaporation ponds (per typical brine operations). This can translate to a lower environmental footprint (typically <5% of the land use required for Li projects that produce similar volumes), less ground disturbance (as the Li-void brine can be reinjected back to where it came from, which may also reduce or eliminate the need for large tailings ponds), potentially less fresh water and energy usage, and overall, fewer carbon emissions (especially if the company is aiming to direct-ship its final Li-chemical directly to end-users rather than shipping to an intermediary, as is the case with most hard-rock Li mines, which ship a Li-concentrate to China for downstream processing).

Watch canadian environmentalists and first nations delay then sink the project like they are doing for the lithium mines in Québec.
Canada has a lot of lithium ressources, yet the only operating mine is owned and operated by China and all of the lithium is shipped to China.

I’m on board with what you’re saying, but will this still be a problem after a few years of successful clean hydrogen? As in aren’t they all just waiting to be proven wrong until they’re forced to change?

The recent lithium developments in Canada, particularly the Kindersley Lithium Project in Saskatchewan, are expected to have a major impact on Tesla's supply chain, as the company relies heavily on lithium for its electric vehicle batteries. The Canadian lithium deposits are becoming increasingly attractive to not only Tesla but also other major automakers like Volkswagen and General Motors, who are looking to secure their own lithium and battery supplies. These developments could accelerate the adoption of electric vehicles in North America and highlight the potential for sustainable transportation in the future.

Sorry if I’m wrong but does the process create a toxic waste? Couldn’t it just be put back into the ocean?

It does, however, escape from containment very easily and float away into space.

The us spent tons of money researching iron based batteries, succeeded then gave the technology to China and made it illegal to make them in the United States. We are now backtracking trying to tell China they can’t use the technology we just handed them. Typical us politics.

Trying to revive traditional sailing for modern commercial shipping is a dead end. It requires too much manpower (meaning: more than current commercial shipping requires) to operate these, too much maintenance and too much deckspace. Add to that the relative unreliability because the wind is not always blowing of course and it is just not economical viable.
The solution to still use the wind as a power source is to use Rotor Sails (Flettner Rotor) - these can be fully automated, require very little maintenance, have a 8x higher efficency per area and require far less deckspace compared to traditional sails.
However, if we still want our cargo delivered in the same reliable time schedules this will only always be an additional thing to the diesel main engine. It makes not yet sense to have the main engine be electric on such large ships, because the required battery capacity would require an enormous volume of batteries.
As far as sailing goes I think the rotor sail is the future.

Tbh I didn't think it was that hard, but then seawater has a lot of contaminants that could block the basic clean water plus electric idea I assumed was already well established.

Total BS, sorry for a couple of of very BIG reasons We just “borrow” water with law salinity and we will re introduce it in the cycle. There is very little water that is ever lost.
The total amount of human consumption of fresh water is just insignificant, not even measurable, with respect the total amount of water on this planet.
Bottom line: water does not exist in a “state” but in a dynamic cycle. Altering this dynamic cycle to a measurable amount requires a scale that is far bigger (many orders of magnitude) and does not take into account negative feedbacks to the process of increased salinity, like the increase of low salinity water coming from the waste product of this process
