Interesting, googling around a bit it looks like it is basically soybean oil, whey, and dextrose with vitamin powders. So pretty much the same as Soylent. I guess worries about bioavailability are overblown given that coma patients survive indefinitely, but then again, their mixture is adjusted daily based on blood work.
Rob Rhinehart's food replacement Soylent now has a crowdfunding campaign.
If you're interested in one or more of these benefits, send in some money! There is also a new blog post.
