From Dual Universe Wiki
You will have to "unlock" technologies to make advanced Elements (like a new type of propulsor) or advanced crafted items (like a new type of fuel). The way to unlock these technologies remain to be decided. There are currently several ideas.
- Unlocking through research time
- RNG mechanics but relying on luck for research
- Grinding significant amount of specific resources
- Through "trials & errors" experimentation
- Civilization-wide unlock
