Hey, hi, i like the idea
its been hours i try to add a second fuel to it, do you have any suggestions ?

could i use this on my base?

As a "starting" energy source it is a great solution, however generating 20 MW is a bit of an exaggeration compared to hydrogen engines. At least get these engines to be used for takeoff without causing a shift from hydrogen to oxygen engines

However, I appreciate it for a great mod.

Oh and crasy idea here but maybe make an air vent that looks like a small turbine for the air intake and o2 compression that way it would look nicer in front of the plane instead of the vents, or one that fits in front of the engine as a grill ( i really enjoy exposing the moving parts of the engine in my ships for the looks ,with an air vent "grill" in front of it would look dope ! Lol ( air vent same and shape as engine one block long) just a noob shooting ideas here =D

Hi would you be able to make a tiered version, twice as powerful with twice or 3 times the oxygen need to balance it out a bit? Awesome work by the way love your mod!

anyway to make them not as loud

Curiosity. Will this mod ever become more than this? I'd really like to see it expand into some new grounds

Thanks for the input

мощности конечно маловато,и весит много,в отличии от уранового реактора.но учитывая то,что это вечный двигатель без дополнительных затрат,это многое ему прощает)))

Done

Could you add "Oxygen" to the title so this is easier to find?

That would take a lot of scripting work that I simply dont know how to do. And the intent of this mod wasn't to be realistic, but instead to add a simpler alternative for refueling airplanes and other such vehicles. If a person want to use so many air vents that it breaks the balance of the game, I feel that was their decision to do. It's like using a mod for ore detectors with a range of a few kilometers or so. It breaks the game play by removing the need to search each asteroid, but if the player wants to play that way, that is their choice.

also have a second "converter" block that turns hydrogen into that special fuel to cause it to have the fuel needed

so a special "air intake" that uses air and produces an item instead of power, that item gets fed through the "converter" which gets turned into a usable fuel for the engine, but you could have it so that it checks whether or not its connected to too many air intakes which would cause it to be overpowered, but also only check when a change is made to the grid

what im suggesting you probably do is to make it so it takes a fuel that a certain block makes, which causes you to make a system, but makes it so that you use FAR less fuel with the system rather than just the engine

I tried dual fuel, but it doesnt work. And I plan on releasing an update that will add more variants with varying amounts of power. No known release date, since it is tied to another mod I'm working on that will use these.

I like the Idea of the mod, but balance I suggest having it consume hydrogen and oxygen but at a higher efficiency than the vanilla hydrogen engines. As if it only consumes atmosphere they can be abused for permanent power source planet side for bases etc.

i had no idea that an airplane engine looks more LIKE A SHIP ENGINE! But what do i know about giant machinery for light vehicles like planes (Sarcasm btw! Nice mod!)

No problem.

Right, I think I get it. So while this engine uses air, the amount required is not easily provided with just one or two air vents.
Thank you for clearing that up, I love seeing mods introduce interesting mechanics like this.
I sincerely hope that I didn't come across as the 'I know better' type. That wasn't my intention.
Either way thanks again; happy engineering :)

And yes, I did put a lot of consideration into the fact that they were more or less infinite power generators while trying to balance them, and in the end the current setup seemed to work the best.

The initial idea of these engines was that they would have the same power output as the h2 engines and be used to trickle charge batteries on an airplane, but then I thought that it made more sense if the engines themselves were the source of power

The engines provide four times the power as the vanilla h2 engines while require double the components with some extra power cells on top. And if you only use one or two air vents per engine it will only be able to sustain full power for 15 to 20 minutes. (I haven't measured yet) I've come to think of the engines as air batteries, with air vents being sort of a weak source of input.

How much power does this currently generate?
I assume that it's the same as a vanilla H2 engine?
If so, considering as you say it's 'free energy', I feel that that may be too much. Since an initial greater build cost still potentially provides an infinitely greater return when compared to the H2 engine.
I realize that I'm probably being picky with how little power they generate in the first place, but since the H2 engine consumes a fair amount of H2 I feel that this is a reasonable consideration.
Because, why wouldn't you then simply just replace all your H2 engines with these for the same amount of power with the H2 use?

Other than that, this is a great idea. And by no means do I want to put you down.
Keep being creative :) And in the end, it's your mod ;)
