Hello Jed,
If water boils at 99.6 degr C the airpressure must have been 1000 mbar, but
according to this site:
http://www.worldweatheronline.com/sports/football/weather/Italy/1175869/Bologna-Fc-1909/2638541/info.aspx?day=21
the airpressure on April 28th 2011 was 1011 mbar, so the boilingpoint must
have been 99.9 degC. The difference in boilingtemperature can be
explained by the accuracy of the thermometer (+/- 0.4 degrC).
To conventionally explain the boilingpoint of 100.5 degrC the backpressure
in the Ecat must have been 30mbar (for a boilingpoint of 99.6degC) and
20mbar for a boilingpoint of 99.9degC. This compares to resp 30.6 cm and
20.4cm water and this is about the hight of the chimney. The difference in
temperature of the steam can ofcourse only be explained if the chimney of
the ecat is almost completely filled with water. This is ofcourse the big
question.

It is very important to notice that water boils at 100.5 C when the
outside air pressure is 1030 mBar, which can be the case when a high
pressure system is covering Italy . . .
In the April 28 tests, Lewan reported: "we calibrated the probe by
immersing it in a pot with boiling water, and the measured value was then
99.6 degrees centigrade." Later during the test they measured vapor at
"about 100.5 degrees centigrade." There is no doubt that was vapor, since
it is substantially hotter than the boiling water, plus you can see steam
coming out of the pipe. I expect that backpressure is minimal with this
system.
