What is your favorite backyard-shed invention?
Short answerThe panel offers high-pressure steam engines, Rolls-Royce development, the eight-gun fighter calculation, and several compact wartime weapons as favorite examples.
NotesThe question invites examples of consequential inventions developed or refined outside large formal laboratories. Suggestions include the Rolls-Royce Ghost or Phantom, the calculation that British fighters needed eight .303-inch machine guns, and weapons such as the Sten gun, grease gun, and specialist SOE equipment. One panelist chooses Richard Trevithick's high-pressure steam engine work in South Wales. The range of answers shows that the 'backyard shed' label can cover private tinkering, small shops, and estate workshops rather than one precise type of workplace.
