Dear Colleagues.

Greetings. We had a most productive conference call yesterday that a total of 19 people were in on at various times. We learned and discussed highly important and valuable information on both the technical and policy aspects of this project that I think are important for everyone to hear. 

We had the great honor to have Prof. Trevor G Marshall, PhD join us. Dr. Marshall is Director of the Autoimmunity Research Foundation in Thousand Oaks, California and is also a member of prestigious organizations in Brussels, Germany and Moscow. Dr. Marshall not only has a working knowledge of both the physics and engineering aspects of radio frequencies and the technologies that create them, including cell towers and the types of transmitters that Google and others are testing on balloons and drones, but he is also knowledgable on the physiological and health effects of exposure to these frequencies on human health, both the thermal and non-thermal, biological effects. His website is .

Most recently, Dr. Marshall presented a lecture entitled, “How Radio Waves Make You Sicker; Environmental Radiation Modulates Symptoms in Human Immune Disease”. This was presented at the 5th International Symposium on the Interaction of the Nervous and Immune Systems in Health and Disease in June 2015 in St. Petersburg, Russia. The link to his 20 minute talk is . A PDF copy of the written abstract is here: . A PDF of a recent paper (cited on slide 3) describing the Foundation's earlier research, "Inflammatory Disease and the Human Microbiome" is available from: . 

Dr. Marshall went into detailed descriptions on yesterday’s call of the expected impact of the radio frequencies reportedly to be transmitted from Google’s balloons and drones, as far as we know from the data we have from Google’s FCC filings. He has been following this for two years and helped Alasdair Philips with his calculations of power flux density that Alasdair reported to us two seeks ago. 

The important thing to know is that Dr. Marshall says what others have already told us, that the strength of the radio frequency signals from these balloons and drones floating or flying twelve miles up will be quite low once it reaches the ground relative to other RF transmitters we are already exposed to at ground level. This is contrary to what some individuals have assumed must be the case for the RF waves coming to earth from Google’s balloons and drones. We understand that there could be the conclusion that since the signal has to travel quite far, it must be made stronger than what is transmitted from land-based antennas. However, that is not the case, according to Dr. Marshall and others. 

This is because it turns out that wireless devices have the capacity to successfully receive radio signals at extremely low levels, lower than you think, and these sky- and space-based transmitters, which are powered by solar panels and not the electric grid as land-based cell towers are. will take advantage of that fact. People are surprised to learn that your cell phone shows five bars when the RF signal strength it is picking up from the distant cell tower is only 0.01 microWatts/meter squared (µW/m2) or 0.002 V/m or -50 dBm/m2.  The cell phone can still connect to the tower at 1 bar, which is 0.000025 microWatts/meter squared (µW/m2) or 0.00001 V/m, which is almost 100 times lower than five bars.

Also, the understanding that because a signal from a balloon covers up to 100 miles on the ground it must be strong is also not true, because any land-based transmitter that is not designed to have a narrow beam, as point-to-point microwave transmitters have, will also spread out to a 100 mile diameter many miles out, however the power density of all radio transmissions decreases exponentially with distance by the 1 over r squared law (where r is distance). This means, at half the distance to zero field strength, the strength of the radio signal decreases to one-quarter, not one-half of what it is at the source. Thus the signal gets lower even faster than the distance away from the transmitter.

Dr. Marshall’s findings corroborate with what Alasdair Philips, Yuval Tsur and other engineers have been telling us for weeks now, that the signal strength from these sky-based transmitters, no matter what frequency, will all be much lower than what the general public is exposed to from the router, laptop, tablet, cell phone, cordless phone and cell towers in that most people use or are exposed to, by several orders of magnitude. 

I am still working on my draft of a more detailed summary of the technical aspects of this project, but according to the numbers that Yuval and Alasdair crunched, it boils down to: 
  • Expected thermal effect values at ground level from balloons and drones in the neighborhood of 1-2 microWatts/meter squared (µW/m2) or 0.02 V/m and -51 to -47 dBm from point-to-point transmissions at 70-90 GHz, which Dr. Marshall says every balloon will transmit, and 
  • Expected thermal effect values at ground level of 0.0006 to 0.003 microWatts/meter squared (µW/m2), or 0.0005 to 0.001 V/m or -83 to -77 dBm/m2 for frequencies transmitted in the 2400 and 900 MHz range, respectively, which is what Google used when they tested their Titan drones in 2014 
Dr. Marshall says LTE will probably be broadcast by Google in the unlicensed 3.5 GHz band, which will produce RF power density levels at ground level similar to the levels just mentioned. 

These LTE values are well below the beginning of the No Concern range of the Building Biology profession’s guidelines for safe EMF exposure, which begins at 0.1 microWatts/meter squared (µW/m2) and goes down from there, and the values for the point-to-point transmissions are in the slight concern level. The table is found at . 

We also have more data in applications that Google filed with the FCC in October 3015 that Arthur Firstenberg found by searching the FCC database using the applicant name, Alphabet, which is the parent company of Google, but the ground-based power density levels will be the same.

Dr. Marshall also went into great detail on how shielding differs at different frequencies. There are many factors that need to be taken into consideration to properly and effectively shield one’s home and also one’s person against these radio waves with the use of RF-shielding fabric. I will share this information in the technical statement I am preparing. Dr. Marshall is working on a silver-based fabric to provide effective shielding of the head and body. For more information on that, contact Dr. Marshall at . 

In summary, the RF power density values anticipated from Google’s balloons and drones are expected to be quite low at ground level compared to the RF levels many people are exposed to in homes and neighborhoods from a growing number of sources at ground level, which are often measured at thousands of microWatts/meter squared (µW/m2). There will be more ground-based RF from the Wi-Fi repeaters in Google's red balls affixed to people’s homes and cell phones will have to "work harder" to transmit back up to the sky-based receivers on the balloons and drones. 

We did agree that these low RF levels that reach remote areas would be a problem for electorally sensitive individuals. That is a given, which everyone agrees with. So-called “white zones” will be needed, and this was discussed.

Needless to say, these RF power density values don’t reflect the non-thermal health effects for everyone from these extremely short, pulsed digital radio signals from the transmitters on these balloons and drones. This will have an affect at even extremely low power density levels. Electrically-sensitive individuals are particularly sensitive to these non-thermal effects, but they affect all of us on a cellular and psychological level, not to mention what all of this does, even at low levels, to bees and other insects, animals and plants.

I honestly will not have time to provide a more detailed summary than what I have presented here (outside of the technical statement I am working on). That is why I highly recommend that you listen to yesterday’s call to hear this important information directly for yourself if you want more details. I will eventually summarize it in a technical statement.

At roughly the 112 minute mark, we get into a detailed discussion of policy for the remainder of the call. This discussion was started by Debora Kopald (not Devra Davis, as I initially thought) and others. We covered many of the points already under discussion by the larger group. I suggest you listen to this portion to hear what policy points were discussed and Dr. Marshall’s comments. 

We will have another call this coming Sunday, the 17th, at 8 AM Pacific Time.

Instructions to Listen to Yesterday’s Conference Call (January 10, 2016)

You can listen to a recording of yesterda’s call from the Free Conference Calling website. If you follow the instructions below, it will take you to the page for the conference number I have been assigned (973494), and the recording is posted there. Future recordings will also be posted on this page.

Go to . On that page, scroll down to the "Listen to Recordings” button on the right side of the page. Once you click that, you will be asked to type in your first and last name, your email address and the conference code number, which is 973494. Once on that page, you will find the recording for yesterday’s call, labelled, "Project Loon Conference Call -- January 10, 2016". You can listen to the call on your computer by starting and stopping the recording using the player that you see just under the title.

Sorry, there is no way to listen to the recording of this call on a telephone. It has to be done through the Free Conference Calling website and listened to from a computer (which is no cost to you nor to me as the host). This is a free service but there are limitations. Another conference calling service I used had toll-free call-in phone numbers, including from overseas, and you could listen to the recorded call from a telephone as well as online, but it was quite pricey.

Instructions on How to Access Future Conference Calls

To call in to future conference calls, which we are currently having every Sunday morning at 8 AM Pacific Time / 11 AM Eastern Time, use the following instructions:

Dial-in Number: 1-302-202-1104 
Conference Code: 973494 

Note, this is a toll call and is the only phone number you can use to access this service from the US or any other country. Skype is a good way to call in to a toll number from anywhere in the world for a very low cost.

Once on the call, we ask that if you are not speaking, you please mute your phone by pressing 4* (4 star) to keep background noise to a minimum. When you want to speak, you can un-mute by pressing 4* once again. 

(End of call-in instructions)

All the best.
