While sitting here nursing a King sized cold I caught the trailers and first episode of a new (to me at least) programme on the Yesterday channel called "The Re-Inventors". Did anyone else catch it?
This seems a similar programme to Mythbusters but the technicians build and try out old inventions. The episode I saw involved a 19th century proposal for a solar powered crematorium! The final 'coming next time' section shows them building a medieval Chinese flame throwere, and the trailers seem to include a number of items with military applications, including a Da-Vinci machine gun and what looked like a Prussia (?) 19the century helmet gun.
I could be worth finding appropriate episodes.
