Rescued East African slaves taken from a dhow aboard British naval ship HMS Daphne. They were freed from Arab slave traders in 1868.



Ziplines act like little magnets, repelling each other when they need to cross paths (vid @ 2x)

Almost everything is way less figured out than you think



There's middle ground in this dichotomy, of course. There's various uses for all sorts of gear. And urban guys can have a rural mindset. But preparedness isn't a COD fantasy. The rural preparedness mindset is all about utility and being a legitimate asset to your friends & family






A maritime drone campaign of unprecedented scale. Robert "Madyar" Brovdi, commander of Ukraine's Unmanned Systems Forces, announced that drone operators targeted a staggering 90 Russian vessels in the Sea of Azov between July 6 and July 12. The massive coordinated operation hit a wide range of logistics assets, including oil tankers, tugboats, ferries, and dry cargo ships. According to the General Staff of the Armed Forces of Ukraine, these specific vessels were actively backing Russian military logistics and moving petroleum products to bypass international sanctions. Ukraine has effectively turned the Sea of Azov into a no-go zone for Moscow's sanctioned supply fleet. #SeaOfAzov #DroneWarfare #Madyar #UnmannedSystems #UkraineWar #MilitaryLogistics #BreakingNews

If successful, lithium-air batteries will kick jet fuel out of the sky and bunker fuel out of the ocean. "Mainstream lithium-ion batteries have an energy density of ~250-270 Wh/kg, while future solid-state alternatives are expected to achieve ~500 Wh/kg. Lithium-air configurations present a theoretical energy density limit of 12,000 Wh/kg, a ceiling that matches the energy capacity of conventional gasoline."
