About the Dyson Cube Project mod
With Dyson Cube Project you can build your very own Dyson Sphere like megastructure in Minecraft and unlock limitless energy for your world.
🔧 How it works:
- Send Solar Sails and Beams to the sun using EM Railguns, EM Railguns can only work during non rainy days, and they will stop working when the sun is at its peak (By default you need 1 beam to support 4 solar sails)
- After sending a bunch of solar sails you can harvest the power (FE) using Ray Recievers
(All multiblocks can be connected from the bottom middle block)
The EM Railguns work without power but when provided with power they will ramp up how many items they are sending each time. You can connect power to the middle pillar of the multiblock.
In multiplayer other players can join your sphere by interacting with any multiblock and clicking on the button on the bottom left
