Google Testing Project Loon: Concerns Are Without Factual Basis (thestack.com)
An anonymous reader writes: In a filing submitted to the FCC, Google has stated that while concerns for health and environmental risks posed by Project Loon testing were 'genuinely held,' 'there is no factual basis for them.' Google's filing attempts to address a wide range of complaints, from environmental concerns related to increased exposure to RF and microwave radiation, to concerns for loss of control and crashes of the balloons themselves. First, it states that its proposed testing poses no health or environmental risks, and is all well within the standards of experimentation that the FCC regularly approves. It also pledges to avoid interference with any other users of the proposed bandwidth, by collocating transmitters on shared platforms and sharing information kept current daily by an FCC-approved third party database manager.
I have no idea what Project Loon is. One line to explain it in the summary would have been nice.

Duh. Why do you think I wear the tinfoil hat? To get chicks? No, to block all that stuff from hitting my brain AND to get chicks. Chicks love shiny metal.
If you browse through the FCC database and read the objections to date, what you'll find is mainly a bunch of "OMG! Electromagnetic radiation will poison us! Stop Project Loon!" It's the tinfoil hat crowd, the ones who think that WiFi and cell phones are giving us brain cancer. Some of their letters are good for a laugh, but they're not a serious threat to Loon.
The serious objections will come later, from telcos who find their wireless rate models undercut by Google, or by petty despots who absolutely, positively do not want Google giving cheap Internet access to their subjects.
There are legit concerns of google just swarming over the world and stomping over any existing carriers
Increased competition is not a "legit concern".
Communities should be able to choose how to evolve their infrastructure
Individuals should be able to choose what infrastructure they use. This is not a decision to be imposed by "communities".
FYI, there are biophysical effects to cell radiation. Well documented, published research from prestigious institutions has shown that under exposure to cell phone frequencies that bacterial and mammalian cells produce a lot of lipids. Why this happens is not known. One of the speculations is DNA is being activated by the radiation. At first this seems impossible to believe since the wavelengths of the radiation are orders of magnitude larger than the size of DNA. But models have shown that it does not take a lot of energy to cause Diploid DNA to separate into two strands. What happens if resonance occur and small "bubble" openings between the strands ripple along the chain. Thus very tiny amounts of radiation can affect the DNA. Where these opening occur depend on where a resonance condition can occur. Thus it is possible to imagine selective activation of parts of the DNA in the presence of cell phone radiation. Controls have shown the effect is not due to heating and a number of other possible laboratory artifacts in setting up the tests. Since there is no way yet to observe the predicted DNA response and the models are idealized it's not known if that happens in real cells or if that effect is any way connected to the observed lipid production. None the less what you can say is:
1) it's not crazy to say Cell phone radiation can selectively excite DNA
2) Cells do repspond inthe presence of cell radiation
Thus while there is as far as I know zero evidence of direct damage to a multi-cellular human, the fact that it can act on individual cells is cause for further study.

Signal strength decreases with distance squared, so a 12 kW signal from a balloon 20 000 meters away is as weak as a 0.3 W signal from a WiFi router 100 meters away.

Mammalian Stem Cells Reprogramming in Response to Terahertz Radiation
http://journals.plos.org/ploso...
We report that extended exposure to broad-spectrum terahertz radiation results in specific changes in cellular functions that are closely related to DNA-directed gene transcription. Our gene chip survey of gene expression shows that whereas 89% of the protein coding genes in mouse stem cells do not respond to the applied terahertz radiation, certain genes are activated, while other are repressed. RT-PCR experiments with selected gene probes corresponding to transcripts in the three groups of genes detail the gene specific effect. The response was not only gene specific but also irradiation conditions dependent. Our findings suggest that the applied terahertz irradiation accelerates cell differentiation toward adipose phenotype by activating the transcription factor peroxisome proliferator-activated receptor gamma (PPARG). Finally, our molecular dynamics computer simulations indicate that the local breathing dynamics of the PPARG promoter DNA coincides with the gene specific response to the THz radiation. We propose that THz radiation is a potential tool for cellular reprogramming.

Intense THz pulses cause H2AX phosphorylation and activate DNA damage response in human skin tissue

Recent emergence and growing use of terahertz (THz) radiation for medical imaging and public security screening raise questions on reasonable levels of exposure and health consequences of this form of electromagnetic radiation. In particular, picosecond-duration THz pulses have shown promise for novel diagnostic imaging techniques. However, the effects of THz pulses on human cells and tissues thus far remain largely unknown. We report on the investigation of the biological effects of pulsed THz radiation on artificial human skin tissues. We observe that exposure to intense THz pulses for ten minutes leads to a significant induction of H2AX phosphorylation, indicating that THz pulse irradiation may cause DNA damage in exposed skin tissue. At the same time, we find a THz-pulse- induced increase in the levels of several proteins responsible for cell-cycle regulation and tumor suppression, suggesting that DNA damage repair mechanisms are quickly activated. Furthermore, we find that the cellular response to pulsed THz radiation is significantly different from that induced by exposure to UVA (400 nm).

That's great but Google are using gigahertz frequencies, not terahertz frequencies. There is a three order of magnitude difference. This roughly the same as the difference between visible light and extreme UV/X-rays and there is clearly a huge difference in how these two types of radiation interact with the body.
Google has stated that while concerns for health and environmental risks posed by Project Loon testing were 'genuinely held,' 'there is no factual basis for them.'
While Google's belief that provably invalid health and environmental concerns aren't important in a political matter might be genuinely held, there is no factual basis for that belief.
