And no, unlike the Green version, the ingredients for Soylent do not include human.

Earlier this week came the news that NASA have invested in a printer that creates food from powder.

Rob Reinhart has taken that one step further by creating a powder-based drink which he’s lived almost exclusively off for several months.

The electrical engineering and computer science graduate created the formula as he felt he was wasting time with traditional meals, calling it an “ancient method”, and has raised almost $250,000 to create Soylent on an industrial scale.

"I wanted to have enough freedom over my time and money, and I wanted to be healthier” Reinhart says in the promotional video for the substance, “I've lived almost exclusively off Soylent for three months.”

His detailed blog confronts many arguments posed against his "new food", saying “Soylent is probably not going to solve hunger, obesity, and health in one fell swoop. But I certainly think it could help. And I certainly think these problems are worth working on.”

Described as tasting like “cake batter”, Soylent is made up of all the base ingredients the human body needs to function, including micronutrients and probiotics.

Reinhart admits that he hasn’t given up regular food completely and eats it once or twice a week.

It seems like almost like a scam or some crazed bedroom experiment, but DNews consumed it exclusively for a week and found that they experienced no ill effects, at least in the short-term.

The video below details their experience, right down to some rather intimate details.
