Technical Research

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
