A company called Texzon is developing wireless power transmission based on the "Zenneck wave" theory, a ground-wave technology related to Nikola Tesla's early 20th-century work. The CEO claims the system is safer than current RF standards and could eventually provide commercial-grade power over any distance.

Brussels became the first major city to halt its 5G rollout due to health concerns regarding RF radiation. In the U.S., the town of Moraga is fighting the installation of small cell towers, though local governments face legal hurdles from the FCC that prevent them from citing safety as a reason for denial.

The debate over the border wall is framed as a conflict between Trump's physical barrier and Silicon Valley's preference for an "electronic wall" consisting of high-tech surveillance. One host shares personal experiences with "RF burns" from amateur radio equipment to illustrate the reality of radio frequency hazards. The discussion concludes with a proposal for "5G crystals" or wearable LED armbands that light up when high levels of radiation are detected.

Edward Snowden, collaborating with designer Andrew "Bunny" Huang, unveiled a mobile phone case designed to alert users to electronic surveillance. The device is intended to detect RF signals that indicate a phone is transmitting data even in airplane mode. The project was presented via video link at an MIT event, sparking debate over the ethics of working with the whistleblower.

Following the discussion on cell phones, the hosts share their personal precautions regarding radio frequency (RF) exposure. Adam Curry mentions his respect for high-frequency equipment after suffering an "RF burn" from a low-wattage transmitter. John C. Dvorak admits he uses speakerphone and avoids carrying his phone in his front pocket, reflecting a general caution toward long-term radiation exposure.

Applebaum suggests that the NSA's "CTX 4000" continuous wave radar device could be responsible for Hugo Chavez's cancer by radiating individuals with high-power RF energy. One host, a licensed amateur radio operator, dismisses this as "bullshit," explaining that the power levels described (up to 1 kilowatt) are standard in amateur radio and would not cause cancer from a distance.

The hosts debate the technical feasibility of claims made by author James Bamford regarding NSA satellite interception of point-to-point microwave transmissions. While one host dismisses the idea as "bullshit" due to the directional nature of microwaves, the other argues that atmospheric scatter and low-earth orbit satellites could theoretically allow for such collection.

A military surveillance blimp designed to operate at 60,000 feet crashed over Philadelphia, prompting a discussion on the high-end camera equipment used in such craft. Advice is offered on how to scavenge expensive lenses from crashed military hardware while avoiding detection by disabling RF transmitters.

The hosts reminisce about early Research In Motion (RIM) messaging devices from the mid-1990s, which used high-wattage PC cards to send emails. Curry describes a flight where he and a colleague sent messages back and forth from their seats, potentially causing the pilot to report navigation system issues. They discuss the high levels of radio frequency (RF) interference emitted by early portable electronics like CD players.
