So effectively the millimeter waves (5g) are acting very similar to a microwave (oven). I guess the power levels matter alot here, also im sure there are some resonant
frequencies that would cause different effects. But sounds plausible they could start fires. nostr:npub1nf9vm6uhs4j7yaysmjn9eqlf7et5t6hvrkdqgpd995vcc9yfjyas0pxa3x
I’m curious if they have actually activated these yet.
I guarantee that they can cause fires with correctly sized magnetically susceptible particles of sufficient size, and sufficiently high energy levels.
You would be familiar with how a coathanger wire gets hot when you bend it. The changing of the geometry of metals opens up gaps in their semi-crystalline structure that heat escapes from. Microwaves induce this on a very small scale, in a conventional microwave it's around 2-3x the diameter of the faraday cage mesh in the front door, for a millimetre wave, obviously it's 1/10th or so this size, getting smaller as you go up the spectrum until you get to infrared.
Really, photons and electrons are the same thing just that photons have wavelengths that are small enough to directly interact with molecules and atoms.
But as for how they cause the fires, my guess is it's not a direct effect, but rather that there is bits of metal around, especially the soil, the microwaves heat them up until they emit enough infrared that nearby, dry plant material like dead grass or eucalyptus leaves, especially those, since they are full of flammable oils, have enough kinetic energy to start reacting with the oxygen in the air, and voila, fire.
Great point
A material's opacity, refraction, and reflection of EM radiation is highly dependent upon the frequency. Within the microwave frequencies (1GHz-1THz, or 10⁹-10¹² Hz), materials act quite differently event within that range, and we literally see very different effects in the visible spectrum (400THz-800THz, or 4-8 × 10¹⁴ Hz), demonstrated most pointedly by pigments and gel color filters. It's all one phenomenon: electro-magnetic waves.
For one good example, human skin is virtually transparent to NIR, near infrared, light. We see red light therapy on the rise with lots of people experimenting. The light penetrates the skin and enters muscle, causing relief and stimulating healing. And then we have infrared cookers that have high intensity infrared light that, similar to red light therapy, penetrates the upper layers and get absorbed deeper into whatever meat you're cooking, that is until you generate a crust which will absorb more and be less transparent. Your infrared cooker and your red light therapy lamp are using similar frequencies at vastly different intensities.
The same goes for Wi-Fi and milimeter wave 5G versus your microwave oven. The 5G tower would need astronomical power to heat a car to combustion. Don't build your home near it, but a safe distance should reduce the intensity to the point of safety.
Human bodies are quite transparent to the radio frequencies, but absorption does increase with frequency from radio to microwave. At 0.1 GHz, absorption is about 10cm (meaning the EM waves are absorbing at low intensity, and the power density would be quite low).

I share this not because I do not think caution is necessary with EM, but just to put it into perspective.
### As for 5G used for causing fires.
We should consider the power levels of a 5G tower. Let's say 10kW for easy numbers. That 10kW is not entirely focused, so let's say at just 1m away an object might experience about 5kW/m² max, or about 3-4 times the intensity of the sun at sea level. The power drop-off for EM is inverse-squarely proportional, meaning that power at 1km be 5mW/m², much less intensity than putting an LED bulb against your skin.
Let's say the tower can output 100x power for a few seconds, and you're only 100m away (or a football field for those at home): that would produce a whopping(!) 50W/m², which may hurt but would not be high enough to cause huge temperature spikes. For reference, the inside of a microwave over is on the scale of 10-250kW/m² (1000x), and the sun at sea level is about 1400W/m² (280x).
A 5G tower would have to create an incredibly coherent beam to measurably increase the temperature of anything at distance. As far as I know, beam forming is not nearly effective enough to do that.
I wasn't really the one talking about 5G radios, as much as they already have proven powerful enough to cause small birds to internally rupture, I was thinking of directed energy weapons that are specially designed precisely to focus such beams, for the express purpose of causing metallic materials to heat up.
I'm talking about the kind of power level, at a burst, that you find inside a domestic microwave, contained to an area of similar size. This is quite easy to do, and I'm sure there is probably dozens if not hundreds of devices floating above us in low orbit with this capability (via a small nuclear reactor and large capacitor).
Really good insight thanks.
