In part to resolve this and related questions about the dangers of industrial accidents and popular fears of runaway events equivalent to Chernobyl and Bhopal disasters , and the more remote issue of ecophagy , grey goo and green goo ( various potential disasters arising from runaway replicators , which could be built using mechanosynthesis ) the UK Royal Society and UK Royal Academy of Engineering in 2003 commissioned a study to deal with these issues and larger social and ecological implications , led by mechanical engineering professor Ann Dowling . This was anticipated by some to take a strong position on these problems and potentials — – and suggest any development path to a general theory of so-called mechanosynthesis . However , the Royal Society 's nanotech report did not address molecular manufacturing at all , except to dismiss it along with grey goo
