📱 eBook en inglés FLOATING STONE

During the height of the World Wars, the global demand for steel outpaced the capacity of massive industrial nations. With German U-boats sinking cargo vessels faster than they could be traditionally replaced, the Allied forces faced a crippling logistical crisis. In a desperate bid to maintain the vital supply chains across the Atlantic, engineers turned to a highly counterintuitive building material: solid concrete.
President Woodrow Wilson initially approved the Emergency Fleet Corporation to build these experimental vessels, and the concept was revived during WWII. Using a specialized lightweight aggregate reinforced with steel rebar, shipyards poured and molded massive cargo ships. Despite the obvious psychological hurdle of trying to float thousands of tons of rock, the physics of water displacement held true, and the "Liberty Ships of Stone" successfully took to the seas.
Floating Stone explores the forgotten history of this bizarre wartime innovation. It details the incredible engineering challenges of casting enormous hulls in a single pour and the strange experiences of the sailors who lived and worked inside damp, echoing concrete caverns.
Discover the fate of these unsung workhorses of the war. While too slow and rigid to survive long-term maritime use, their ghostly, indestructible remains can still be found today, serving as breakwaters and haunting monuments to wartime desperation.
