Normally, I don't pay attention to the private ventures of rich billionaires, but this one is a rare exception for how insane it is. According to Luxurylaunches, Gabe Newell, the co-founder of Valve and Steam, has recently signed a contract with the Norwegian shipbuilder company VARD to build a new research vessel for his Inkfish organization called the RV11000.
Costing roughly $815,000,000, this titanic vessel is being constructed to support submarines and map uncharted depths of the world's deepest, darkest, and most dangerous depths of the ocean.
