600W generating, completely exploit-free SPOM

[Strygald]

I had an idea last night, maybe it's been done before but i'll share it anyway.

SPOM that generates 600W surplus electricity

https://steamcommunity.com/sharedfiles/filedetails/?id=1750455550

Video Notes:
Freshly built SPOM takes a few cycles to "get fully revved up", so the vid covers 5 or 6 cycles.

10 Jumbo batteries are just to give a vizualisation of energy gain, nobody in their right mind would use 10 jumbo batteries in survival - please remember to add +20kj to the Net power gained(to ignore the runoff).

How it works

The SPOM box should be built somewhere near the top of your base with nothing obstructing it nearby.. so above a ladder shaft would be a good candidate. It has 3 electrolyzers and 3 gas pumps above them. So that you have full control over water usage I would suggest using a liquid valve to limit flow to the electrolyzers to 1000g/s, this is so 1/3 of the water goes to each electrolyzer and all 3 will have a combined output of 1 electrolyzer running at 100% uptime. The reason there are 3 is simply because you get better gas dispersion and don't end up with the dreaded 'max gas pressure' ruining your efficiency, which is often the case with 1 lone electrolyzer.

Next, there are 3 gas pumps which suck up the hydrogen(and oxygen) and these also help greatly with preventing 'max gas pressure', all other oxygen produced floats down into your base. Wait! you say, how can you generate surplus power with 3 gas pumps going?! Here's the key: we use an automation pulse 'thingymajig'(the thing under the SPOM box) to only allow the pumps to work every couple of seconds, this vastly reduces the amount of power they use. With the correct settings on the automation pulse you can reliably get very near 100% electrolyzer efficiency.

Here are the settings i'm using:
top buffer set to 1s
bottom buffer set to 4s

The gas pumps suck up both oxygen and hydrogen and send to a custom filtration system(which I wont go into unless someone wants to know), filtered hydrogen gets fed into the generators and filtered oxygen can be sent to far away parts of the base or into exosuit docks, etc..


Results(of the last 5 cycles before I stopped)

Cycle 23
oxygen generated: 539.9kg
net power: 355.8kj

Cycle 24
oxygen generated: 532.8kg
net power: 361.9kj

Cycle 25
oxygen generated: 537.2kg
net power: 382.3kj

Cycle 26
oxygen generated: 525.7kg
net power: 358.1kj

Cycle 27
oxygen generated: 541.7kg
net power: 366.5kj

Average
oxygen generated: 535.46kg/cycle
net power: 364.92kj/cycle

( 364.92 * 1000 ) / 600 = 608

average of 608W surplus power generated per cycle

One electrolyzer outputs enough O2 to keep about 12 dupes alive (unless you have a lot of mouthbreathers), and keep 2 Oxygen pumps almost 100% busy.... suggest you get rid of some electrolyzers and add more pumps!

[jott]

What ddoge said, 1 electrolyzer to 2 gas pumps, I myself usually pump it through 2 filters, and send the o2 through some warts to cool it, and the hydrogen self sustains it all with some slight excess production, I usually keep it seperate from my main powernetwork, with automated switched feed in if it ever stops to jumpstart it back up. it's completely self sufficient that way. excess hydrogen goes off to get used elsewhere, it's honestly not much.

[Ruggy]

I was wondering if you cool the oxygen at all.

Yes, pipe the oxygen through the cold biome, a room full of wheezeworts, a room with an active anti-entropy thermo-nullifier, or a thermo-regulator.

Guys, please read the post more carefully. The main reason to come up with improved SPOM(self powered oxygen modules) designs is to squeeze more out of them.

You both describe the basic setup:

liquid pump 21W, power cost to supply electrolyzer with 1000g/s water
gas pump 240W, 100% uptime
gas pump 240W, 100% uptime
electrolyzer 120W, 100% uptime
gas filter 0W, assume using automation filter

Total wattage: 240W + 240W + 120W + 21W = 621W

So, you put in 1000g/s water and get out
888g/s oxygen
112g/s hydrogen

Converting all of the hydrogen to electricity will give you: 896W - 621W = 275W surplus


With my SPOM design:

1000g/s water in
888g/s oxygen out
112g/s hydrogen out

Converting all of the hydrogen to electricity will give: 600W surplus

Which would you rather have? 275W of extra power or 600W of extra power per installation?

Multi pump set ups don't run the pumps full time. They automate to atmo sensors so they only send full packets. Its more efficient than what you are doing. Also you can avoid using filters of any kind, either the (maybe exploity) mechanical or the powered kind by allowing gravity to filter for you. In the best set ups you can get a permanent layer of hydrogen above the electrolyzer that never gets any oxygen in it.

I'm with promethian. Filters are easily replaced by the natural force of gravity and atmo sensors help a lot. This is my set up.

Or use "hydra" scheme (familiar half-bug schematic). Electrolizer and filter, all in one.

Oh? I (friendly)challenge you to calculate how much surplus electricity your SPOMs generate every cycle and tell me if it's as good as or better than 600W!

[Prometheus]

Don't need to. If your pumps ever send a half packet of a gas at any time we are being more energy efficient than you. If you are worried about raw power, it takes two pumps to move the full output of an electrolyzer. So your set up has the electrolyzers running half as often as one of ours. Which is half the hydrogen produced.

Your set up offers no advantages. Its not energy efficient, its not getting the maximum use of the machines, it requires a filter. You are several steps behind the meta. Do you even realize that long term self powering isn't even the goal? Hydrogen is used as rocket fuel plus running the AETN is very valuable. Hydrogen is also the best gaseous coolant. There are more uses for Hydrogen than to feed back into your power grid.

The gas pump to electrolyzer ratio is 2:1.
This is going to get to max pressure eventually and shut down like others have stated (until the pumps catch up).
Also you'll probably need to dump this much oxygen into vacuum or you're going to over-pressurize the entire map and make the game unplayable, so space suits and a long pipe are required.
You're also omitting the power cost of the liquid pump as if it doesn't cost energy.

Overall - try again.

I'll answer you first as it'll be quick:

I am including the cost of the liquid pump, examine the screenshots ... I always have "yesterday's report" open so you can see. In the screenshot it says Liquid pump -13.2kj which is approximately 21W .. this is a fixed cost since it always costs the same to pump 1000g/s water in an electrolyzer each cycle.

Every oxygen-producing setup, from the simplest to most complex, will eventually get max pressure and shutdown if you don't manage gas on your map, when I post SPOM designs I assume the player at least knows how to manage gas in their game... that is if you have too much either cut down on how much you're producing, get more dupes or vent it off into space(dig an opening up into Space), etc...

LOL, I see... unable to back up your nonsense with any actual hard data.

Extracting maximum oxygen and hydrogen for the lowest energy cost is the goal of SPOM designs, even at end-game when you might want to use all of your hydrogen for rockets you will still want to extract maximum oxygen and hydrogen for least energy cost, that never becomes irrelevant... I can't believe you failed to understand that.

I can tell you right now your SPOM is pretty crap, it is in a closed box so in order to move out the 1000g/s the electrolzyer produces you need to spend at least 480W, any less than that and your electrolyzer will stop due to 'max gas pressure'

120W + 240W + 240W + 21W = 621W to produce approx 888g/s oxygen and 112g/s hydrogen


Here's another screenshot, with yet another report open:

530.1kg oxygen produced
514.4kj electricity produced

electricity removed:
Liquid pump -13.2kj
Gas Filter -20.6kj
Gas Pump -48.1kj
Electrolyzer 59.7kj

Cost to extract: 141.6kj or 236W

So, yes try and actually test my SPOM design before trying to crap all over it, it just makes you look silly.

[Just a dog]

So if you're not going to be using the oxygen, why not just make 1 electrolyzer and 2 pumps? Or 1 of each if you don't like being efficient. What's the point of having 3 of each? 600W isn't worth the effort. Might as well just build one coal generator and be over with it.

[Just a dog]

You obviously haven't tested your own design. Why not test it yourself in survival before you praise it?
