I'm afraid that is a common misconception which was mentioned on this list shortly after the January demo... http://en.wikipedia.org/wiki/Relative_humidity "Misconception Often the notion of air holding water vapor is presented to describe the concept of relative humidity. This, however, is a misconception. Air is a mixture of gases (nitrogen, oxygen, argon, water vapor, and other gases) and as such the constituents of the mixture simply act as a transporter of water vapor but are not a holder of it. Humidity is wholly understood in terms of the physical properties of water and thus is unrelated to the concept of air holding water.[3][4] In fact, an air-less volume can contain water vapor and therefore the humidity of this volume can be readily determined. The misconception that air holds water is likely the result of the use of the word saturation, which is often misused in descriptions of relative humidity. In the present context the word saturation refers to the state of water vapor,[5] not the solubility of one material in another." NOTE the statement: "In fact, an air-less volume can contain water vapor and therefore the humidity of this volume can be readily determined." And secondly, liquid water HAS gases dissolved in it... Have you ever heard of a "dissolved oxygen meter"? I have one. What oxygen are fish 'breathing' in water? It isn't the oxygen in the H2O molecules. So the vapor in the E-Cat has other gases in it (most likely at much lower concentration than air), but even that is irrelevent to this issue. You do not need 'AIR' to be present to measure RH. -Mark -----Original Message----- From: Mattia Rizzi [mailto:[email protected]] Sent: Thursday, August 04, 2011 7:21 AM To: [email protected] Subject: [Vo]:Re: [e-cat] Engineer from delta ohm confirms that galantini instrument is useless > RH is simply the amount of water vapor that CAN exist in a given volume of *air* at a given pressure and temperature There is NO AIR inside e-cat.
