Origin Adelaide Type Worker Co-op Stage Concept

Noteworthy This is incredibly innovative and ambitious concept.

Sea level rise is already flooding many people’s wells and forcing them to move.  This project directly aims to improve the lives of 100,000,000 people today and as climate induced sea rising gets worse this technology will become more important.


TideWater – will make fresh water from the sea by reverse osmosis, powered just by the tide and gravity.

Usually reverse osmosis requires pressures that are generated through running an engine on fuel, biodiesel or some finite source.

This design works by filling a long narrow tube with water from the incoming tide.  This sends tube vertical. As the tide goes out this sends tube horizontal. This gravity-powers the reverse osmosis filter.  The process repeats once the tube empties, refilling again on the next tide.


  • It will take no fuel to make fresh water from the sea.
  • Production costs per unit are estimated at less than $15,000
  • Export market opportunities

Hurdles: This idea is at concept stage and so there is a need to create a Proof of Concept, business model and structure.

What they need: 

  • Prototype Design
  • Money
  • Advice

What is the Accelerator Program?

Beginning on the 4th of February and running for 8-weeks is the first Accelerator Program being run for creating new member-owned organisations.

There are already many incubators for investor-owned companies and even some incubators for social enterprises, but this is the first incubator run to assist the creation of new member-owned businesses.

The incubation process takes an idea – or Project – through 4-stages: Forming, Organising, Funding and Operating.

A project is improved upon at each stage with the direct assistance of the membership of Incubator Co-operative.  For example a Project might need a website and they will agree a deferred-payment arrangement with a web designer who is also a member of incubator.coop.

Not all projects will offer deferred-payment arrangements, some will pay directly for work, some will ask for a freebie and some will offer the equivalent type of sweat-for-equity arrangement that a startup might provide.

Incubator.coop provides the ‘ecosystem’ that allows members to assist Projects through the critically important early stages of formation, planning, launching and compliance of member-owned organisations.
