Daniel_Stuckey writes "Less than a year ago, Rob Rhinehart published a blog post explaining how he had stopped eating food and begun living entirely on a greyish, macro-nutritious cocktail. Today, he told Motherboard that he's sold more than $2 million worth of Soylent to tens of thousands of post-food consumers worldwide—and that it's on track to ship next month. 'We have crossed $2,000,000 in revenue from over 20,000 customers, with more every day,' Rhinehart told me. 'International demand is really picking up as well.' This despite the fact that Soylent isn't technically on the market yet, and has thus far only been available to beta testers. Rhinehart's company spent much of last year tinkering with the formula—the version he tried first was deficient in sulfur, and contained since-jettisoned ingredients like cow whey. But there's been a steadily building crescendo of publicity—both positive and negative—around the project since its inception."
