"Development of mining technology able to extract gold, silver and rare metals lying untapped on deep seabeds in Japanese territorial waters will start this year, government sources have said.

By bringing together advanced technologies in robotics and deep-sea mining, the government will develop a mining system using the world's first deep-sea mining robot to excavate minerals, which will then be transported to a support ship on the surface via a pipe.

The government will start experiments this year on a submerged test model, with a target of putting the system into commercial use in about 10 years, the sources said."

Given that the program has just begun, I think it's reasonable to speculate that this initiative is motivated by China's head start in mining the yellow sea.

Precious metals like gold and platinum are plentiful enough around hydrothermal vents (and easy enough to get at) that the profit model works out. But there are also rare earths, necessary for electric vehicle batteries, which I believe is China's main reason for developing a nationalized deep sea mining program. Japan recognizes the threat this poses as they are home to many of the world's largest auto manufacturers, so they've followed China into the sea, where tomorrow's resources will come from.

as long as they stay within their territory I have no problems with it.

but if they mine an inch outside of it, and it's on.

They're on the right track. Before we try going for the crapshoot of settling space, we should focus our efforts on colonizing and exploiting the ocean.

We've reached the point where the necessary technologies have fallen in price and become universally available such that a private organization has the means to set up a sea floor community. Which is what the Atlantica Expeditions is doing:

"Development of ass mining technology able to extract poo, shit and rare cum lying untapped on deep ass regions of my dad's ass will start this year, government sources have said.

By bringing together advanced technologies in anal robotics and deep-ass fucking, OP will develop a ass mining system using the world's first deep ass mining robot to excavate used condoms filled with my own cum from my dad's ass, which will then be transported to a support ship on the surface via a pipe. I will then use them in sucking off my dad.

OP will start faggot-ass-fucking experiments this year on a submerged hairy father ass model, with a target of putting my cock into commercial use in gay porn in about 10 years, the sources said."

Given that the program has just begun, I think it's reasonable to speculate that this initiative is motivated by my other brother's head start in mining my dad's mouth with his cock.

Precious metals like poo and cum are plentiful enough around hydrothermal vents (in my dad's ass) that the profit model works out. But there are also rare anal beads, necessary for sustainable gay porn, which I believe is my brother's main reason for developing a gay deep ass and mouth mining program. OP recognizes the threat this poses as they are home to many of the world's largest dildo and anal bead manufacturers, so they've followed my brother into the ass/mouth mining business, where tomorrow's resources will come from.

My understanding is that no nation owns sea floor land beyond 12 miles from their shore. Certain laws continue to apply until 200 miles out, and then anything goes. So nothing prevents a nation with the necessary technology from setting up a seafloor mine or aquaculture operation in international waters except the difficulty of defending it.

Here's two Nuytco deep worker mini submersibles commonly used to supervise/maintain the robotic equipment employed at seafloor mines. The Chinese mining program likely has something similar, but you couldn't pay me enough to get inside one.

There's this stuff called methane hydrate. Ice that burns. An energy dense fuel source that we haven't exploited until now because the largest deposits are under the arctic/antarctic oceans and we don't have the technology to set up mining operations in such a hostile environment as of yet.

The nice thing about an underwater city would be that all the cars are 'flying' cars since it doesn't take them any energy to hover, they just gotta be neutrally buoyant.

The only reason that has gotten any attention as a possibility is because a lot of dumbfuck eco warriors don't know it's still a carbon based fuel.

Hydrocarbon fuels are too potent to simply ignore. The trick will be finding more efficient ways to extract energy from them while releasing cleaner emissions.

Natural gas fuel cells are actually more practical than hydrogen fuel cells right now. The 'bloom box' backup energy modules are natural gas fuel cells, with 50% energy efficiency versus 20-25% for a car engine.

Fuel cells on an automotive scale will probably not catch on for a few decades more as currently they wear out faster than lithium batteries and cost more. But scaled up for buses, long haul trucks and so on, they last much longer and begin to make financial sense.

I expect most passenger automobiles will be battery electric within 50 years, and UPS trucks, semis and stuff like that will use fuel cells.

Cars have a few places to go outside of fossil fuels besides nuclear energy.

Personally, I don't cars will go from being fossil-fuel centric to solar centric/battery centric. It's very likely that, unless the entire world is fucking retarded, multiple types of vehicles will be introduced.

It's also possible that mass transit will take an even more important place in society.
