Hi, My name is William Nelson, I have been an environmental since 1969 and have discovered many confirmed solutions having to do with environmental problems, mostly dealing with preventing the spread of radiation such as preventing radioactive waste. I have been to Chernobyl 3 times and have spent time within reactor # 4 and have solved some of their problems such as preventing the escape of Plutonium dust from escaping the Sarcophagus. During my research, I discovered a combustion rocket without a motor, not a solid-fueled rocket. Anyone interested?
