Hoover Dam is an engineering marvel.

Standing 726 feet high and 1,244 feet long at the crest and costing $50 million at the time ($1.2 billion today), Hoover Dam is made from an astounding 3.25 million cubic yards of concrete. This is enough to pave a two-lane highway from New York to San Francisco.

While it cures, concrete heats up and potentially could crack. To prevent cracking, engineers poured concrete into 215 interlocking vertical blocks and stacked them in a staggered pattern. They also included over 590 miles of 1-inch steel cooling pipes in the concrete blocks to channel chilled river water through the concrete as it cured.

Patented columnar construction and cooling system technology made this possible, for example, U.S. Patent Nos. 1,889,268 and 1,888097, both issued to Henry Sorensen in 1932.

Hoover Dam is a symbol of the power of American ingenuity, innovation, and perseverance. Visit America’s Innovation Agency to protect your intellectual property for the next engineering marvel:

Record-low water levels on the Danube River have exposed dozens of German World War II shipwrecks near Prahovo, Serbia, where around 200 N**i vessels were deliberately sunk in 1944.

The ships belonged to Germany’s Danube and Black Sea flotillas, which were scuttled to block the river and slow the advancing Soviet Red Army during the war.

Some wrecks still contain ammunition and unexploded ordnance, making recovery dangerous while restricting commercial navigation and costing Serbia an estimated €5 million annually.

An EU-backed project is removing the most hazardous wrecks, while others remain buried beneath the riverbed because they are too risky to recover.

Experts say extreme heat and drought are exposing long-hidden wartime relics and reshaping Europe’s archaeological landscape.
