I also can't connect to the TPT server to download simulations. I love trying out mod elements in Destroyable City to see if I can make better nukes, but Powder Sim won't connect to TPT server.
Also the noble gases should produce SOME heat when turned into plasma by electricity (maybe 900DegC) so it's hot enough to make the metal electrode glow (not hot enough in Powder Sim now), but not so much it melts the metal (as it does in TPT, which means TPT has it too hot)
I am no longer a developer for Powder Sim. In my opinion, I don't think I have the skills to help build this simulator. I will be now assuming a role as a member. @me4502, please change me to a member in the groups section. Thank you.
