i kind feel iridium doesn't have enough uses. granted is hard to aquire till you get a significant amount of power generation going or a Scrap Farm. but once you get that you tend to have more iridium then you'll ever use as long as you keep your quantum armor charged. so i thought of a few new, fairly realistic uses.
1: Iridium Reactor Plating: this would be an internal Nuclear Reactor component to increase Hull Temperature Capacity by 2,000. this would make breeder reactors alittle easier and help prevent reactor explosions. the recipe would be 4 iridium plates, 4 advanced alloy, and 1 diamond.
2. Iridium Heat Dispenser: this would function the same as the current Integrated Heat Dispenser but would also cause .5 of coolant power up from the IHD'ss .1, would require 1 reactor heat dispenser, 2 iridium plates, 2 advances alloyed, 4 coolant cells.
3. Iridium Wiring: EV wire that cannot be insulated, but only loses 1 EU every 10 blocks. this would be great for transfering energy over really long distances or upgrading the current EV wiring in your house for the use of teleporters and creating large scale Field Generators. however: since they cannot be insulted it runs the risk of killing anyone who touches it when charged, so you have to be careful with your wiring. recipie would simply be 3 iridium ore in a line to create 6 pieces of wire. this would mainly be used to force field generation and Teleporters, as it losses the same amount as Glass Fiber Cables, simply on a scale of 4-1. this could also be used as the most powerful electric fencing.
4. Iridium blocks: Show off how effective your Mass Fabricators are by creating Iridium Blocks! a simple block made from 9 iridium ores that have a sleek Pearl like look to it. these blocks would also be the most explosive and heat resistant material in the game (since iridium is only .12% less dense the the densest material known to man). A wall made 2 thick of iridium would stop a reactor explosion.
