Dams might work on Titan but....

An underground Dam? Could it work on Mars??

Revolutionary new Swiss 'water battery' will be one of Europe's main renewable sources of energy. Pumped storage power plant was built into a subterranean cavern in the Swiss canton of Valais, battery is located 600 metres underground (1,969 feet) between the reservoirs of Emosson and Vieux Emosson, actual turbines are underground, not sure if it has enough power and I think there are regulations on Swiss exporting energy to Europe.

https://www.euronews.com/green/2022/06/ … -shortages

If large quanity of Water is found a Dam could be put near one of the hotter geothermal regions that encourages evaporation and underground 'rain'. Korolev Crater is estimated to contain 2,200 cubic kilometres (530 cu mi) of water ice and more than 5 million km3 of ice have been detected at or near the surface of Mars, enough to cover the whole planet to a depth of 35 meters (115 ft) more ice is likely to be locked away in the deep Mars subsurface, underground Water would be sealed inside a Mars cave causing Less Loss of Waters Less evaporation.

Mars_B4_Moon,

These people are "battery crazy". It's a hydroelectric dam. Calling it "a water battery" doesn't change what it is or how it functions.

SpaceNut · 2022-07-04 13:42:21

Since it's got to be pumped in its now a reservoir of water as in kinetic storage. it seems to exit the cavern without pumping.

NASA has a plan for mini nuclear reactors on the moon which could one day power a lunar colony

https://www.businessinsider.com/nasa-pl … ?r=US&IR=T

The reactor, shown in the video below, would generate about 1 to 10 kilowatts of power continuously for at least 10 years. That's much smaller than the nuclear power plants on Earth, but it is enough to power several average households.

Mars_B4_Moon,

These people are infinitely more committed to their religious ideology than they are to the people they sleep with, and till death do they part. It's a garden variety death cult. It's exactly what it appears to be, which is why it looks so much like a death cult. They want to keep the majority of the people cold or hot and preferably, to starve them to death. Poor people don't use much energy, because they can't afford to. This "new economic model" (austerity) is exactly like "the old economic model" (austerity). Artificial scarcity is baked into the Russian and even European psyche. I don't know why exactly, it just is. Maybe it's the end result of centuries of trying to mass murder each other. I guess they think the privation they cause each other is "normal", even though it's not.

Promising new catalysts for hydrogen fuel cells
https://phys.org/news/2022-07-catalysts … cells.html

In new interdisciplinary research published in ACS Catalysis, Northeastern scientists have identified a novel class of catalysts that, because of their particular non-noble-metal nature, could replace the platinum-based standard that has prevented hydrogen from advancing in the fuel sector.
"We are quickly transitioning to electric modes of transportation, and as I see it, batteries are only a transitionary phase," says Sanjeev Mukerjee, a distinguished professor of chemistry and chemical biology at Northeastern, who is a co-author of the study. "It's not the ultimate answer to replacing fossil fuels."
It's in hydrogen, or "hydrogen carriers"—larger molecules in which hydrogen is just one part—that the answer lies, he says. The most abundant element in the universe, hydrogen acts as an energy carrier and can be separated from water, fossil fuels or biomass and harnessed as fuel. Hydrogen fuel cells convert hydrogen into electricity; and unlike the internal combustion engine, which produces toxic and carcinogenic chemical byproducts, hydrogen fuel cells only produce water—actual drinkable water—as a result of the chemical reaction.
"The biggest bottleneck right now is, one: infrastructure for the fuel, i.e., hydrogen or a hydrogen carrier; and number two is the high cost of catalysts, because the current state-of-the-art requires noble metals," Mukerjee says. "So there are dual efforts to both lower the noble metal loading and find more sustainable catalysts using elements that are very abundant on earth."

Well I sort of have an attraction to one of the subtopics of the previous post by MbfM.

This one: "Green Ammonia To Rescue US Farmers From Fertilizer Supply Woes"
https://cleantechnica.com/2022/07/25/gr … pply-woes/

In the article they talk about using offshore winds. Using remote energy sources that are otherwise hard to connect to grids, to produce chemicals seems very sensible to me.

I have previously had a look at the "Roaring 40's".
https://en.wikipedia.org/wiki/Roaring_Forties

Roaring Forties
From Wikipedia, the free encyclopedia
Jump to navigationJump to search
For the electric company, see Roaring 40s.
Not to be confused with Roaring Twenties.
The Roaring Forties in the Cook Strait of New Zealand produce high waves, and they erode the shore as shown in this image.
The Roaring Forties are strong westerly winds found in the Southern Hemisphere, generally between the latitudes of 40°S and 50°S.[1] The strong west-to-east air currents are caused by the combination of air being displaced from the Equator towards the South Pole, the Earth's rotation, and the scarcity of landmasses to serve as windbreaks at those latitudes.
The Roaring Forties were a major aid to ships sailing the Brouwer Route from Europe to the East Indies or Australasia during the Age of Sail, and in modern times are favoured by yachtsmen on round-the-world voyages and competitions. The boundaries of the Roaring Forties are not consistent: The wind-stream shifts north or south depending on the season.
Similar but even stronger conditions that occur at more southerly latitudes are called the Furious Fifties and the Shrieking or Screaming Sixties.

So, the 50's and 60's as well

No stationary wind platforms for this, rather ships with sails and dragging a water turbine behind them.

But there are winds in the Atlantic and Pacific that may be more local for various nations.

So, now perhaps a method that works for people like North America and Europe and people also compatible in nature such as Japan and others of that region.

I think this may be much more accessible than fusion power at this time.

I wonder what such ships would look like? Super Tanker sized?

And the sails.

This is a thing that all Technical, Industrial, and even the Religious Greens should support. And a national security item, so it should be of interest at the highest levels, I would think. I can see North Europeans, Japan and other pacific rim nations and indeed Canada and the USA to be interested.

And as the motor fuel is also fertilizer, I cannot see agricultural nations not be interested.

I was thinking of just one drag turbine on a ship, but now I think many, and so they could have magnetic drag imposed on them selectively to help navigate the ship. But of course if you are running an Ammonia engine(s) to propel the ship they would be drag, but maybe not too bad at low speeds. Maybe it need a bit of work.

Maybe the turbines could also serve as propellers when needed.

Done.

US regulators will certify first small nuclear reactor design

https://arstechnica.com/science/2022/07 … or-design/

Small modular reactors have been promoted as avoiding many of the problems that have made large nuclear plants exceedingly expensive to build. They're small enough that they can be assembled on a factory floor and then shipped to the site where they will operate, eliminating many of the challenges of custom, on-site construction. In addition, they're structured in a way to allow passive safety, where no operator actions are necessary to shut the reactor down if problems occur.

The designs for a 300-megawatt SMR might have enough electricity to power approximately 230,000 homes a year?

and some others want to Tax the Sun!?? because a Grid is now getting too much power

'When the sun switches off the solar panels'
https://www.france24.com/en/live-news/2 … lar-panels

this in a ways is a lying misleading headline, the Sun isn't switching off the panel, he's getting disconnected by human political policy

Munich (Germany) (AFP) – The more the sun shines in the southern German town of Aurach, the more likely it is that Jens Husemann's solar panels will be disconnected from the grid -- an exasperating paradox at a time when Germany is navigating an energy supply crisis. "It's being switched off every day," Husemann told AFP during a recent sunny spell, saying there had been more than 120 days of forced shutdowns so far this year.

Interesting technology: Cast basalt lined steel pipes.
http://m.duratecceramic.com/cast-basalt … -pipe.html

Highly corrosion and abrasion resistant. This may be a useful technology for fabrication of AHR, PWR and BWR primary and secondary side systems on Mars. It would allow the use of plain carbon steels or cast iron, in aqueous environments, without concerns for corrosion. On Mars, we will need lots of energy, in the form of electricity and heat. Low grade heat will have abundant applications in agriculture. This means that our nuclear reactors do not neccesarily need high efficiency, as waste heat will have abundant uses.

In the early years of Mars colonisation, it will be more important for nuclear systems to be cheap, simple and easy to build and operate, rather than being super efficient. For water based reactors, this allows outlet temperatures to be relaxed and primary circuit pressures as well. At a temperature of 150°C, water saturation pressure is about 4.8 bar.
https://www.engineeringtoolbox.com/wate … d_599.html

Pressures this low allow cast iron to be used for pressure vessels, with the static pressure of soil in the ground providing back pressure as well as functioning as shielding. Heat exchangers can be fabricated from basalt lined steel tubes. In the case of the aqueous homogenous reactor, the vessel would contain a cylindrical core shroud, with fission taking place within the cylinder and the hot fuel solute rising by natural convection. It would exit holes in the top of the shroud and flow down through heat exchangers, before reentering the core. The blades and nozzles within a steam turbine need to be constructed from stainless steel. However, almost every other component can be either cast iron or carbon steel. Presumably, fixed blades can ve cast iron as well.
https://www.hhitmc.com/eng/products/steam.html

Raising steam at 150°C would limit the plant thermal efficiency to about 20%. That means 4 units of low grade heat produced for every unit of electricity, assuming a condenser temperature of 300K (27°C).

An AHR operating in this way would not in theory need any pumps. The turbine and generated are the only parts that must be moving. Heat transfer between the fuel fluid and heat exchangers is through natural convection. On the secondary side, gravity head could be used to provide return condensate with the 4.5 bar of pressure head needed to flow back into the boilers. But on Mars, this would mean building the condenser on top of a hill. Feed pumps negate the need for this, but will likely have to be imported from Earth. Decay heat removal could be achieved through a bypass loop from the heat exchanger directly into the condenser. Emergency cooling could be provided by having a heat exchanger within the cast iron reactor veseel that results in conduction through the metal. If you allow heat to be list by boiloff into the Martian atmosphere.
