Objectives

  1. Remix / design and prototype a mid-size plant protein extractor.

  2. Evaluate its performance.

  3. Distribute the extractor directly to local producers or through NGOs.

Description

A leaves blender is a device used to extract leaf concentrate, which can be of high nutritional value. Leaf concentrate is essentially a curd, produced by coagulating the juice of fresh green leaves. Leaf concentrate is also known as leaf protein, leaf protein concentrate, leaf nutrient, and leaf extract. Most of the research for making leaf concentrate has been done by Leaf for Life, a non-profit promoting the eating of green. Example of a leave blender for leaves concentrates.


The primary goal of this project is to create a fast, efficient, and easily scalable method to produce leaf concentrate (between DIY home and industrial-scale) during a food shortage. Two organizations have worked on village-scale leaf concentrate manufacturing: Leaf for Life and Association pour la Promotion des Extraits Foliaires (APEF). These two organizations have made impact macerators for leaf concentrate production. These macerators function well but are not suited for the purpose of being laterally scaled. These designs require many custom parts and high energy processes like welding and machining. The goal of our design, on the other hand, is to have an easily replicable design with stock components and minimal use of custom parts (unless they can be digitally fabricated with a RepRap class 3-D printer or CNC mill –e.g. limit to what is found in most fab labs and avoid high energy processes and a skilled machinist). The designers should seek to minimize cost and complexity while keeping throughput high (continuous if possible).


This project will design and make an open source leaf macerator/blender or shredder.


Project nature

This is a sponsored project, i.e. an organization is paying us to do the work.

Deliverables are open source with commercial rights granted.


Project requirements

Need to be developed using only OS tools (e.g. OS CAD-like FreeCAD or OpenSCAD) and be digitally replicable (e.g. make the pulleys 3D printed primarily from a RepRap-class fused filament 3D printer) and only common cheap off-the-shelf components (e.g. cheap reliable electric motor).


Deliverable

Source code (CAD in native format and STL), full BOM (component, number, cost, and source), build instructions with pictures, operation/maintenance instructions, video of operation and prototype sent to the Project Sponsor


Other conditions

The Project Sponsor would retain first academic publication rights (with Sensorica co-authors if wanted). At the time of academic paper submission full open source documentation released to the world.

Incentives

  • Money: This is a financially sponsored project, you'll get paid in proportion to your contributions.

  • Entrepreneurial opportunity: This is an open source project, you can use the prototype and the business model that we will design around it to start a small family business.

  • Learning: This project is a great opportunity to experience and learn an open source hardware development methodology, to experience a highly participatory work culture, and learn about the technologies used in the project. You'll also be exposed to collaborative entrepreneurship and collaborative business models.

  • Exposure: Co-author one or more scientific papers that are planned to be written on this device and process.

  • Networking: Get to know people with various skills, some of which are versed in p2p economics and collaborative entrepreneurship.


It's up to YOU to extract some or all the above benefits :)

Governance

more on Governance page
PROJECTS are seen as COLLABORATIVE VENTURES, which are TRANSPARENT (anyone has access to the information that they produce) and OPEN (anyone can participate). They only produce PRODUCTS and services based on OPEN SOURCE knowledge or technology. PROJECTS have a CUSTODIAN that represents them legally and acts as a trust for their tangible assets. PROJECTS can have multiple EXCHANGE FIRMS, which are commercial entities that move products and services developed by PROJECTS on the MARKET. EXCHANGE FIRMS oblige themselves by contract with the CUSTODIAN to share PROFIT with all contributors to PROJECTS, from which they commercialize PRODUCTS.
