Graphene is quite silly when combined with near perfect atomic assembly. You can create some very stupid weapons with it, like the railgun below.  You can also make massive radiators that weigh next to nothing and super-thin engine bells. In modern times we cant do this because graphene loses its properties when assembled into large sections but in CoaDE we have seemingly perfect manufacturing techniques that may allow us to bypass this issue. Edit: This should probably go under the science and technology board. Attachments:

Try it with a 2.31g armature but no payload. Doubt it will behave remotely the same.

Well Graphene is a 2D material so you should use carbon nanotube , the 3D version of Graphene instead.

That's why this would only work in game. We have, as I stated in the main post, "near perfect atomic assembly". |

I'm sure this material will be my next choice for railgun construction! Where's the code for graphene/carbon nanotube?
Also, let's not forget boron nitride nanotube.

Here's the code. I gave it the "IsNaostructured" flag to represent the difficulty in building large plates of it. It costs 365 c/kg so large sheets are expensive (the demo railguns cost 12 and 64 million credits).

It costs 473c/kg for me. Was your price from before adding the nanostructured flag? Feels like a cheat code for the universe. Not sure I wanna use it, but it is great for containing the power of other mods like tripropellant rockets. Without the probably extraneous gimbal armour this masses under 50kg and has a TWR over 6kg 0. Well Graphene is a 2D material so you should use carbon nanotube , the 3D version of Graphene instead. You can find the 3D version here: childrenofadeadearth.boards.net/thread/849 |
