(Second-posting this on the "new" thread -- so it doesn't get "lost in Festival limbo"...)

~~~~~~~~~~~~~~~~~~~~~

Kit, this isn't on your "DARPA Tunnels" subject, but...

I could use FReeQs' help on another tunnel-related matter:

I'm pulling the core of my OHI work on the Epstein properties together as a website to be hosted and archived on my own server with pages designed to be published here on our Qthreads.

One subject I'm covering is the Services required to support an extensive tunnel system designed for human occupancy:

1. Drainage (Nobody wants a "wet basement"...)

2. Transport, (Probably electric -- like airport people transporter carts) plus carriers for delivery of supplies & trash, etc. removal).

3. HVAC (Heating, Ventilaton & Air Conditioning)

~~~~~~~~~~~~~~~~~~
I feel confident that I "have a handle on" the first service -- Drainage.
~~~~~~~~~~~~~~~~~~

On LSJI, there are indications that the last two (2) services may be supported by the labeled buildings in this [(low-res) drone] photo:

Both buildings are now "built into a hillside". Their back walls are the hill...

1. The wide "Transport" building with six "arches":
   1. ...is a "false front": the "arches" are, (a la "Trompe L Oeil") painted onto the front wall. The actual doorways are white rectangles.

   2. Before the "arches" building was built, it appears that floor-level concrete "access conduits/passageways" were built -- extending into the hillside. The entrances to those conduits apparently are now concealed inside the building.

2. The "HVAC" building has been discussed at some length online by Anons and others.
   1. I have OHI evidence that, before the hillside was filled in flush with the building, two concrete "access conduits" were visible -- extending from the back wall into the hillside. Those "conduits" are consistent with HVAC ductwork to support the tunnel system.

   2. I recall seeing reports (by Anons?) describing, in detail how the various features of the "HVAC Building" indicated high-volume HVAC service for the tunnel system.

   3. Immediately adjacent to the beach, the water is made turbid by a reddish-brown substance -- appearing to be a "Red Algal 'Bloom'". Someone (Anon?) posted the theory that the algal bloom was caused by nutrients from engine exhaust from the HVAC building -- which emerged underwater just off the beach.

   4. The importance of the above is that the algae bloom could be an indicator of whether the tunnel system is operational -- or not...

~~~~~~~~~~~~~~~~~~~~~~~~

And, now -- my plea for help:

Please share with me any information, links, quotes. etc by Q Researchers...

RE: 2.B., above -- detailing engineering functions that point to the "HVAC" building as air supply for the tunnel system.

RE: 2.C., above -- the theory that the algal bloom was caused by nutrients from engine exhaust from the HVAC building.

~~~~~~~~~~~~~~~~~

ThanQ in advance!!

My source says: HVAC...It could possibly be a passive system whereas the warm water from the evaporative cooling tower is being discharged into the bay producing ideal conditions for algae growth. When you use a closed system you use algaecide and other chemicals to control the algae. Or they could be using seawater for the evaporative cooling tower then dumping it back into the bay.

Tex, I’ll help where I can. I did read the anon digs on the HVAC building being waaay overbuilt for it’s location - indicating it serviced much more than the surface structures. I’ll see what I have in the archives tonight.

As for the algal bloom, I recall that being more of a temperature discussion rather than ‘nutrients from the HVAC exhaust’ it was more like heat from the exhaust making different algae grow in that spot.

Also discussed by anon was your implied, but not stated, drainage. Sewage.

Sewage (treated vs. untreated?) would provide a temperature and nutritional differential for plants. In fact, I thought you had mentioned once that the algal bloom could be caused by dumping at that point on the beach. It certainly isn’t the scenic side of the island.

Critical to know now and in the coming weeks will be whether that bloom returns after this latest storm. Even though Dorian wasn’t a direct hit that I know of, the resulting tidal disturbance may have stripped away some of that algae. If it’s gone and grows back, we can surmise there’s activity. If it survived the storm and remains or gets smaller, that may indicate a decline in activity. If it was swept away and stays away, then whatever was feeding it isn’t anymore.

I’m going to take a stab at the HVAC stuff. I did commercial HVAC for ~35 years.

“Immediately adjacent to the beach, the water is made turbid by a reddish-brown substance — appearing to be a “Red Algal ‘Bloom’”. Someone (Anon?) posted the theory that the algal bloom was caused by nutrients from engine exhaust from the HVAC building — which emerged underwater just off the beach.”

This would be the foundation of any HVAC system, how is it powered? In my experience it would usually be 480 Volt/3 Phase electrical power. Since it’s an island, you could do that with a diesel engine generator to create the electricity. Generally, those would exhaust through the roof. I don’t know you would go to trouble to pipe the exhaust out underground to the water sine it was not a secret the building was there.

I have seen chillers (very large refrigeration compressors that supply cold water to coils in large fan units to supply cold air through ductwork) that were driven by natural gas engines (they could also be diesel) but they were very high maintenance. They were introduced as a “green” alternative, I suppose in the 1980s and were soon abandoned because they were too high maintenance and expensive. That wouldn’t run any of the fan motors anyway.

Either of those would require large fuel storage and there should be evidence of those.

Providing the HVAC system to make underground spaces comfortable would be fairly complex. you would need to control the temperature, obviously, but also the amount of fresh air, the humidity, and the pressure. You would want keep the underground space at a slightly higher pressure compared to the outside so that air (and germs, etc) would tend to go out of the space, rather than into it.

Long way to wonder, why would they vent any exhaust out to the shore line if the whole thing is pretty obvious anyway?
