Radium: Denied. Reason: Don't see a use for it. Radon: Accepted. Development wont start until you give me a colour for it. Bird: Denied. Reason: Use GoL. Seed: Accepted. Bug: Denied. Reason: Use GoL. Dirt: Already added. Tree: Denied. Reason: Use wood and Plant.
i suggested birds and bugs because GoL particles destroy most things they tuch the tree thing is to speed up tree making,so they auto grow from seeds hmm,dident see dirt...or a list of used elements radium could be used for nuclear rods for making steam,then using said steam to generate power also,you forgot to mention C-3,accepted or denied? new suggestion:
Slow,Pressure-less steam STEAM new thing for water,rather than generating Water Vapor,it generates lower temp steam(212 degrees or higher,past 600+ will instantly convert it into vapor),this steam is slower and generates no pressure,but is effected by it,useful for nuclear reactors. color: Cadet blue( http://en.wikipedia.org/wiki/Cadet_grey#Cadet_blue )
