The first generation of Soylent is a powdered food substitute for all your nutritional needs, the second will be a premixed beverage boasting the addition of algae, but the ultimate target is fully-grown, ultra-efficient food equivalent. An eco-friendly paradigm shift, this would allow vast amounts of healthy calories to be created in very small spaces, a single small factory space supplying enough for to sustain the entire city of Los Angeles.

In just a few years, Soylent went from an experimental substance to the household name in food replacement, but its creator’s endgame is far more ambitious than the current niche product might suggest. Soylent 1.0 remains relatively cost-intensive to produce and expensive to consume – it provides simplicity, but only for those who can afford it. Soylent 2.0 will begin targeting broader markets and introduce algae-grown components, but a future version (3.0, perhaps) could truly revolutionize food production and distribution.

Imagine using just water, sunlight, air and a single algae superorganism to generate the complex nutrients (including carbohydrates, proteins and lipids) needed to sustain life, with applications in rich and poor countries (or in space). Then consider having this substance available on tap, piped right into your home like water or power. Alternatively, you might buy your own household bioreactor, churning out Soylent 3.0 directly in your kitchen on demand. Rob Rhinehart’s vision takes various forms, but it comes down to the same thing: an alternative to conventional food and potential solution to unsustainable agricultural practices, available to all those who wish to take part.

Not everyone will want to subsist partially (let alone entirely) on Soylent, now or ever, but that is also not the point – it can always be used in conjunction with other meals by those so inclined or deployed to places otherwise without sufficient food for subsistence. Meanwhile, for the next round (from Motherboard), “The algae [called AlgaWise] in Soylent 2.0 is grown by the biotech company Solazyme, in a facility owned by the Archer Daniels Midland, the food processing giant. The oil is then pressed out much like olive oil. It’s amazingly efficient. Entire tanks can be filled in days.” Solazyme calls the stuff AlgaWise.”

More from Rhinehart on current and next steps: “In the interest of building a sustainable business to fund our research we’ve been focused primarily on product improvements and new products, like the launch today, but I’ve also worked on setting up infrastructure including lab building and recruiting and drawn up a roadmap for reaching the goal of cell synthesis, starting with protein. This process has two modules: one strain engineering to develop and optimize the organism that produces, the other bioreactor engineering to make an ideal growth environment for the strain(s).”

Providing an elegant, robust, accessible and tree-friendly alternative to ladders or branches for climbing trunks, this spiral step solution lets you scale trees without harming them.

Developed by Thor ter Kulve and Robert McIntyre, the CanopyStair uses lightweight birch plywood, adjustable ratchet straps for leveling on uneven trunks and neoprene padding for soft contact points with the tree itself.

As the creators of this system point out, tree canopies are some of the least-explored places on Earth, in some ways as mysterious as the deep oceans or outer space.

The design was inspired in part by a stay off the coast of Portugal in a place with high walls blocking views. The designers found themselves turned into tree climbers in an effort to get a better look at the surrounding vista, then trying to figure out a way to take that approach to the next level, so to speak.

A curved top tread, wooden poles and plastic guidelines all help make the experience smooth and straightforward, letting those who may not normally be able to scale trees still climb them. The team also consulted arboriculturalists to make sure their approach would not damage or harm the trees being employed. The system takes a few hours to set up and as little as 30 minutes to deconstruct.
