Aural Presence: Redux

edit: ok, these are raw video, so they are bigger than youtube or google video, they are 4M and 2M, so be patient while they load, on the other hand, the resolution is much better than if the other services were used.

This is a couple short vids of a long term flowtest of the last well we completed (48hrs of flow) the wells here on blue mountain are quite spectacular, there is enough down hole pressure to start the wells to flow, then, as the column of water in the bore heats up, some of it flashes into steam, lowering the weight of the column, allowing even more flow (not actual weight, but density loss due to flash and increase in the velocity of flow). These tests actually measure not just the amount of water flowing from the well, but the actual total enthalpy from both phases of the flow (steam and water) to get an energy content, thereby knowing how much electricity may be generated by the well. Turn your speakers up just a bit, and the treble down if you can, and under the noise of the wind blowing over the mic, you can hear the low rumble of the flow into the muffler/separator, the mic on the camera doesn't pick up low end all that well (go figure) but it really is an aural presence, the vibration is transmitted into the ground, and felt through your feet as well as felt/heard through the air.


The second vid is of where the James Tube is inserted into the muffler, just so you know, the well is throttled back to about 50% on the control valve, so its not flowing as hard as it could (50% on the valve does not necessarily mean 50% flow, the flow can stop increasing at less than a 100% valve setting) the gauge on the very end of the James Tube reads about 35 psi, pretty good actually (not as powerful as the Puna, Hawaii wells, those things are something else, some of them have been known to flow over a million pounds per hour, this one is (educated guessing here) a bit over 150k#/hr). The ventury effect of the flow into the muffler is apparent, and the rumble is a lot easier to hear from this angle.
