“Dogs on manholes, 8 electrocuted, 6 dead from electrical leakage. One owner hit: “I feel current in my fingers”. What’s going on under the sidewalks?”
“Eight dogs electrocuted in Lombardy. One after the other. They were out for a walk, they were electrocuted as soon as their paws touched the cast iron of the manhole covers, the pedestrian manholes in the sidewalks. It happened in Milan and in the provinces of Lodi and Como Before and after New Year’s Eve. Six dogs died on the spot , two more saved by a miracle. “Mine was struck by a 170 Volt discharge that was passed to me holding it in my arms while it was wet .” Not only that, one of the owners, a twenty-year-old Milanese promoter of the online petition“JUSTICE FOR ALL SHOCKED DOGS. WE WANT CLARITY AND SAFETY FOR EVERYONE ”, it was necessary to seek medical attention. Not veterinary, but for heart tests. His: ” after three days I continue to feel current in the fingers and a general physical decompensation “. The case causes the mayors of the municipalities involved to discuss , Sky , Il Giorno and La Stampa write about it . The mainstream, however, fails to go beyond the surface, providing a general explanation, also taken from Il Corriere della Sera : “Snow and ice end up inside the manholes, thus forming a ‘bridge effect’. The snow is the conductor, the electricity comes out of the cockpit “. For the AGI news agency ” The scientific explanation exists and has to do with snow “. Another thesis is that of the salt , scattered in the streets after the first winter snowfalls: it would have made the water even more conductive of electricity. ” Bad weather in Lombardy, the snow is a killer trap for dogs “, headlines Repubblica .
But one question is missing: how come electricity comes out of the manholes? What is happening under our feet? And under the paws of the electrocuted dead dogs, what was there? We clear the field immediately, although we try to make people believe the opposite: touching the snow does not kill by electrocution . As with the rain water , no one, neither human nor animal, has ever died from having touched it. At most he can act as a conductor , yes, of course, but that’s another matter entirely. Because it was not the snow, nor the water, but the electricity that killed the dogs …”

[BEWARE] Manhole covers do double duty as antennas
“Manhole Covers Serve as Antennas Expanding Wireless Network Coverage
Manhole antenna solution offers glimpse into 5G strategies for signal propagation”
“The inconvenient truth of future 5G networks is that their increased high-speed bandwidth, and the use of the millimeter wave spectrum (the radio spectrum above 30 gigahertz) to achieve it, comes at a price: Those radio signals barely propagate around the corners of buildings.
To overcome this issue, the strategy has been a combination of small cells with massive multiple-input multiple-output (MIMO) antennas to increase coverage. Small cell deployment will be so extensive that the Small Cell Forum predicts 5G small cell will overtake 4G small cells by 2024. The total installed base of 5G or multimode small cells will reach 13.1 million by 2025, constituting more than one-third of the total small cells in use.
So, how do you manage to get all of these small cells dispersed throughout a city landscape where buildings are everywhere and there’s little open space for signals to travel?
Engineers at Vodafone, headquartered in the United Kingdom, have come up with an ingenious solution: make manhole covers do double duty as antennas for mobile communications. This clever solution manages to avoid all the troubling issues that had worried many observers about the proliferation of small cells. It eliminates traffic disruptions from street construction, and there are no antennas awkwardly placed on buildings, marring the appearance of a neighborhood.
This solution is currently being used for existing 4G networks, but Vodafone engineers believe this could be a solution for future 5G networks as well. “The manholes do provide an opportunity to deliver solutions in dense urban environments,” said James Grayling, senior network deployment manager, Vodafone UK.”
