I was actually more worried by the output going into the bucket. I got the impression (but it was difficult to see) that there was a lot of water as well as steam. At 61 mL/min 313 W can raise the water temperature to 92.8 ÂșC. A little extra energy from the device would do the rest, and maybe produce a little steam. I think a proper measurement of the actual output power is now very important. (As Jed suggests, sparge it into a deep container of cold water for a few minutes - while Rossi is not seated at the controls ;) Regards, Robin van Spaandonk http://rvanspaa.freehostia.com/Project.html
