Jones has explained the case better than me. It was a peristaltic pump, see Celani's report "peristaltic pump, small size 10-20 W power" I have used this type of pump for many liquids, including phosgene- so I noticed it immediately. The temperature of the steam was 101 C- and to be again personal when you are burned with it as I was twice, you don't feel the difference.. I hope to see a similar device, if my health permits I will visit Francesco Piantelli this summer and see his cells in action. Peter
