Havana Syndrome could be caused by pulsed energy devices – US expert report

A US intelligence report by a panel of expert scientists has named pulsed electromagnetic energy and ultrasound as plausible causes for the mystery Havana Syndrome symptoms suffered by US diplomats and spies in recent years.

The report found that a group of cases could not be explained by health or environmental factors or by psychosomatic illness. It also said that devices exist with “modest energy requirements” which were concealable and could produce the observed symptoms and be effective over hundreds of meters or through walls.

The panel, established last year by the director of national security, Avril Haines, and the CIA director, William Burns, said the investigation was not tasked to identify a culprit, but in a statement accompanying the report, Haines and Burns said it would help sharpen the search for the origins of they mysterious ailments.

“We will stay at it, with continued rigor, for however long it takes,” they said.

    Lasers ... uhm ...

    So if the diplomat is in the building either

    A: The laser is in the same room as the diplomat being pointed at the diplomat. You would think someone would notice.

    B: The laser is being pointed from outside the building on the diplomat. The laser would have to penetrate various barriers such as walls. You would think that the walls would block most of the radiation and if enough radiation made it through the walls and various barriers it would possibly cause noticeable damage to the walls themselves on their way in the building before reaching the diplomat possibly starting a fire even or at least creating noticeable smoke. Also, the people from outside the building pointing the lasers at the diplomat would have to know where the diplomat is within the building.

    I suppose you can have a scenario where multiple lasers are surrounding the diplomat from multiple vantage points from outside the building and they all converge at the diplomat's exact location so as to amplify the intensity (kinda like how radiation cancer treatments work). The people pointing the lasers would still have to know where in the building the diplomats are and it's hard to imagine that no one would notice that a bunch of lasers surrounding the building are being pointed at the building unless the lasers originated from a far distance in which case much of the radiation would attenuate with distance (plus more would attenuate through the walls of the building but I guess the idea behind this is that each individual laser wouldn't be powerful enough to burn the walls and enough of each laser would make it through the walls so that their combined effect can be powerful enough to do something. It would also be hard to create a small powerful or even an exact convergence target if the lasers originated from afar). This seems far fetched also.

    Or are you suggesting that the diplomats are being targeted while outside the building. So someone in a Jeepers Creepers van is stalking the victims with lasers whenever they step outside the building and no one is noticing. Also seems far fetched.

    I don't know ... the only thing I can think of is someone is aiming x-rays at the building kinda like how x-rays scanners are used to scan trucks at checkpoints. Not a laser X-Ray but a broad x-ray device. Again, I can't imagine that this would be hard to notice (ie: you can test for the presence of high x-ray radiation) and, IIRC (I think this possibility was already discussed in previous discussions), I thought that at one time they did test for the presence of x-rays and the tests showed that there aren't any abnormal levels of x-rays.

    A radio-frequency laser? Also called a radio transmitter?
