Rob Rhinehart is a software engineer, and also the creator of Soylent.

It's not green, and it's not people, but he is hoping that it will replace all the food that you might need in the course of a day.

Rhinehart, 24, claims that Soylent contains all the nutrients a person needs to survive, and he backs it up with his own health.

"[Soylent] now makes up about 90 percent of my meals. I mostly just eat socially now, which is how I think food should be enjoyed," Rhinehart told Here & Now's Meghna Chakrabarti.

Reviews of the shake-like beverage's taste vary.

Adrian Chen at the online magazine Gawker tried some and wrote, "Soylent tastes like the homemade nontoxic Play-Doh you made, and sometimes ate, as a kid. Slightly sweet and earthy with a strong yeasty aftertaste."

Rhinehart has already managed to raise three times more than his goal of $100,000 through an online fundraising campaign, and expects to start delivering his product to customers in August.
