I think TPT should have tritium as an element. Tritium should be used for fusion with deuterium. This will make it easier to make fusion reactors. When fusion occurs with tritium and deuterium, it should make neutrons and helium. TPT should also have helium. helium will be a very light and flamable gas. They should also add sulfur and phosphorus. sulfur will be used with phosphorus to make fire. If you make a box and put a pile of sulfur with a pile of phosphorus it will constantly break down to make fire. this will be another possibility for reactors.
