Rossi used this electronic device for electronic measurement (as was reported) - model HD37AB1347. Relative Humidity probe model HP474AC was attached to it. Page three of this link (thanks to Horace) shows details of that probe connected to the electronic device. HP474AC has the following specifications:
http://tinyurl.com/45rwsvh HP474AC Relative Humiditiy Probe specifications: 5% to 98% RH >>> -40C to 150 C +/- 2.5% (5%...95%RH) +/-3.5%(95%...99%RH) Temp +/-0.3C This probe does not measure the amount of liquid water droplets in the "steam" (ie. mass fraction of water vapor to to total water). It measures Relative Humidity (Relative Humidity measures how saturated the air is for a given temperature). What we want is a a device that measures "quality" of the steam. For reference, 100% quality = 100% vapor. How did they confirm that the water vapor was truly vapor? A visual description would go a long way. As was calculated in a previous email (and shown below), at a hose diameter of .44" (1 cm^2), the velocity of the water vapor should be 198 mph. At .63" inner diameter (2 cm^2) for the hose, the water vapor will be exiting at 94 mph. Also the vapor should be transparent as it leaves the hose until it starts to condense in the air. I read that the steam was vented outside the room. What did it look like in terms of volume and transparentness? I tend to believe that Rossi is legitimate (from what I hear on the grapevine). But we have to have our facts straight when it comes to listing devices that measure relative humidity and saying they measure the quality of the steam. I'm open to the possibility that this probe can measure quality of the steam in some undocumented manner, but let's hear how that is done. The documentation does not say it. ============================================ from a previous email, below are the assumptions used to calculate the vapor velocity: Jeff D. wrote: The calculations of the steam velocity below translates to a 188 mph jet of steam coming out of a hose having an area of 1 cm^2 (equates to a 1.13 cm inner diameter hose or .44" inner diameter) Double the area of the hose and the velocity will drop by a factor of 2 to 94 mph.

This is from an associate LENR researcher - Jeff Morriss, in response to the other issues on steam/vapor raised by Jeff Driscoll and Peter van Noorden, which so far do not have convincing answers. Jeff M. wrote: Nagel states that 150 grams of water are boiled every 30 sec, or 5 cc/sec. Taking the density of steam at 100C as .590 Kg/m**3 and ratio-ing it against the density of liquid water as 1000 kG/m**3 yields a volume increase of 1690. So each 5 cc of water is converted into 8450 cc of steam every second. If we estimate the area of the vent hose at ~1 cm**2, then the steam velocity must be 8450 cm/sec of 84.5 m/sec. This is about 1/4 the speed of sound and should produce quite a jet of steam. Did anyone observe this? Also, the steam would condense and quickly produce a saturated atmosphere and condensation on metal surfaces. Again, did anyone observe this?
