Are Deuteron Fuel Rods worth it?
So 1 Deuteron Fuel Rod produces about 10x the total power of the 10 Hydrogen that goes into it.

But at the cost of a not insignificant amount of non-renewable resources, where Hydrogen is free and infinite if you have oil or a gas giant.

I'm currently making 100MW using just hydrogen and some excess refinery products.

Is it worth it to switch to fusion reactors? I don't really see the benefit at this stage. I can just build more thermal plants for a while. I'm just starting to look into building green cubes, red-purple are currently automated.

You don't have to create Deuteron Fuel Rods and burn them for power if you've got adequate power from renewable sources like solar/wind/burning hydrogen.

However, you will need to create them in order to build the Small Carrier Rockets used to construct the Dyson Sphere itself.

^ what he said. they are great for mech fuel though as they last a very long time, even flying. so you would not need very many, one container would last forever. If you worry about resources then just make them for recipes you WILL need them for.

Oh yes they are 1000000% worth it.

While on paper they just make 9MW of power, that's a consistent power over a long period of time. Once you fill a nuclear reactor you don't have to refuel it much, this means comparatively you can fuel far more reactors for a given production of fuel cells compared to Hydrogen cells in Thermal plants.

Secondly, they are so power dense filling your Mecha fuel chamber with them gives a backup of over 40 GJ of power. That's more than enough for hours away from your power network for when you start taking more and more trips to other planets or other systems.

Are they worth it? Yes, god yes, by all means yes. I've essentially stopped recharging "manually" at Power Poles and just keep Deuteron Fuel Cells loaded up. They last for ages and charge much faster than the Hydrogen fuel cells. You can just set and forget, never needing to worry about recharging until the warning pops up every couple of hours.

They cannot be used as mech fuel.

Last time I tried it rejected to use deuterium rod as mech fuel, was it changed recently?

Very much worth it. 3 assembly plants can power 3 rocket launch pads and fill an entire stack of mk2 storage buildings in short order. use a mix of colliders and those fractioner things, and use a 4 way splitter to loop your hydrogen thru twice. you will BANK deut so fast. i have towers of the stuff.

you sure u didnt grab the other green rod? strange something or other. looks similar, isnt a fuel.

They're absolutely mech fuel. They're the best mech fuel, as they last a very long time.

I haven't used them in reactors though. I have no need for that, as my sphere is putting out 600 MJ of power in the only system I need a lot of it. That's been enough so far, and that number is doubling by the day as I continue construction.

Oi yes, four stacks of 20 and you forget mech fuel is a thing
Rhaane Feb 2, 2021 @ 2:11pm 
Id argue they are required for system to system warping in your mech as not only are they more power but they refill your suit faster as well, without that its such a pain auto piloting in space waiting on power regen.. it still is but without dueterium rods I wouldnt wanna bother
Rhaane Feb 2, 2021 @ 2:12pm 
They are also a great way to jump start a new planet as you can set it up and get things going that may help you get more renewable on-planet power

Yes I do mean the other green rod which is deuterium rod and it is used for fusion reactor. If you mean hydrogen rod, that one can be used as mech fuel, but it is not the one this topic is about.

Looks like you are talking about hydrogen fuel rod, not deuterium one. Hydrogen fuel rod can be used as mech fuel but cannot be used in fusion reactor and this topic is about deuterium rod.

Dueterium Fuel Rod can absolutely be used as mech fuel, You are doing something or seeing something wrong here
