Power source second planet help

[Lwt]

Hello,

I'm playing the Desolands starter planet, but have no water geysers. I'm working on settting up a SPOM on the secondary planet (radioactive ocean).

I know the SPOM is self-sufficient, but I also need power for the following:

- Pump to provide the water
- Salt Desalinator
- Liquid tepidizer (to cool the water to 0 degrees-ish)
- Water Sieve for toilets (minimal use as I only plan to have 1-2 dupes on the planet).

Can these power requirements can be covered by the excess hydrogen and maybe 1-2 dupes working manual generators?

I've thought about solar panels, but they get shut down by meteors, and the meteor blaster seems like a bad idea (no metal volcanoes = no sustainable source for refined metals = no blastshot maker).     

There's plenty of uranium and a volcano on the planet, but using these isn't viable until later.

If I remember correctly, refined metal in blastshot can be recycled after it fired.

Some of them don't run at all time. Also I think you can use cool slush to cool some heat sources in your base before using liquid tepodozer.

For a rough estimate:

• single electrolyzer: 120W
• gas pumps: 480W (3 pumps moving 1000g/s total, i.e. 54W H2 pump, 426W O2 pumps)
• water pump: 36W (1500g/s, because brine has a lot of salt in it)
• desalinator: 144W (1000g/s water output)
• water sieve: 30W? (seems unlikely to be more)

That's a total of 810W. 112g/s H2 generate 896W without further trickery. All this should scale linearly with oxygen consumption (except for the water sieve, but I'm pretty sure I very much overestimated the cost there).

(forgot to mention: the tepidizer is very efficient, and likely only necessary on startup, if at all. Once the system is up and running, the electrolyzer can do the brine heating.)

Blastshot is definitely a bad idea on a planetoid where you are concerned about energy consumption, because they are quite energy intensive. You could try and use automation to only activate them if meteors are coming, but you still need to handle the energy storage.

Also if the meteors aren't too hurty, there is also a zero automation zero brains solution for Solar Power:

The idea is that by overlapping the Robo-miners they can dig each other out and cooled by Conduction Panels. This does involve a small amount of duplicant repairs if there are hurty meteors (generally metal meteors), the repairs will be very cheap, but there's also a good chance you can make the mesh tiles out of the metal ore the hurty meteors are delivering making the repairs fully sustainable.

A similar strategy of Robo-miners digging each other out is also good for keeping Rocket Platforms clear.

Manual Generators do produce a lot of power though, if you aren't doing anything which involves obscene power usage.

Just try it out. I recommend putting in a tank as a buffer.

You could just pump and teleport the salt water as is, process it on your main planetoid and teleport some hydrogen from the spom back to power the salt water pump. Spoms generally create more than enough surplus hydrogen to power the pump that may feed them. Desalination is an other story. A desalinating spom running on brine may hardly be self powering, but a pump is fine.

Hi, if I remember, you have some wood lying around on this planet, if your dupes are leaving the planet (which I assume since you didn't consider the manual generator) maybe you can build a wood burner while you have time to set up a more permanent solution?

If rad ocean happens to have a cool slush geyser bee tinies could be used for power by feeding them to saturn critter traps.

Saturn critter traps are a great source of extra hydrogen, especially if paired with bee tinies to feed them.

16g of polluted water gives you 40g of hydrogen. Better than any hydra can ever be.

2 more suggestions:

• Make a power station and do tune-ups on your hydrogen generators.  You get a 50% increase in power output for a small amount of refined metal (with no increased fuel consumption).
• You can greatly reduce power usage by not pumping the oxygen.  I typically start with open air electrolyzers with a hydrogen collection system at the top of my base.  Then move to a hydra setup which contains the hydrogen, but lets the (high pressure) oxygen diffuse through the base.

Yeah, this works great.  Especially early on when pressures are low.  The only drawback is if you have a world with few or no dupes but you do have various automated systems.  The problem is that your fuel for power is directly related to how much oxygen is used.  If you're not using oxygen, you're not generating hydrogen.

You can get around this by disposing of excess oxygen in one way or another, but if you have a highly-automated world with few or no dupes, you need to find a reliable way to produce power whether or not dupes are breathing oxygen.  Some are more convoluted than others, but I've found that most worlds have some method I can set up that will generate power whether or not dupes are available to provide maintenance.  

• Beetiny/Saturn Traps
• Wild plug slugs with a correctly-sized battery bank.  Works best if you also have a metal volcano and can feed them, but that makes the setup more complicated.
• Pip-planted trees and either burning the wood directly or distilling into ethanol.  You can use sweepys and sweepers to collect the wood and feed it to the distiller or stove and you'll still be power-positive once your trees start dropping branches.  

Spoiler

Or with the new DLC, use seals and bonbons to produce ethanol directly completely power-free.  Use several lumen quartz and some shine bugs to light a tree or two, add a couple wild seals, then a single pump to collect the ethanol.

If you need LOTs of power for an automated world, then things get more complicated, but that should give you some ideas, right?

Wild planted traps produce exactly same amount of hydrogen, isn't it? So, just one suicidal pip per plant is enough
