Open call: Impact 3 billion people

3 billion people lack access to efficient cooling!

The consequences include food spoilage in already deprived areas, increased health risks and limited options for the storing of life-saving medicine and remedies.

We have a plan – it involves our great community – and you 🦾 

Calling all: Engineers, product designers, crafts people, software developers, DIY and open source enthusiasts. Help us develop and build an off-the-grid refrigerator for developing countries.

Inefficient food storing is a significant factor contributing to the continued and growing gap between rich and poor within and across nations. Focusing on India, where power cuts and limited access to water leave many families struggling to break free from their social caste, the refrigeration project sets out to develop an open source off-the-grid refrigerator to circumvent this issue. Being open source means that all design files are freely available online and can be built by anyone anywhere.

The refrigerator prototype will be developed in Viadukten – Maker’s professional workshop under Langebro in central Copenhagen.

How to develop a low-cost, open source, off-the-grid refrigerator 

In cross-disciplinary teams, you will have the option to work closely with Maker (DK) and The Refrigeration Project (UK) on the development of a first prototype, set to be tested in India in real-life scenarios. The 1-week Refrigerator Development Sprint will take place at Maker in central Copenhagen. Our workshop will be equipped with the necessary tools like 3D printers, CNC machines and laser cutters as well as great people, atmosphere and ingenuity.  

When: From March 28th to April 1st at Maker.

Your commitment: To participate in the Refrigrator Development Sprint in a cross-disciplinary team assembled by Maker. We will be working from 9.00 – 17.00 every day during the sprint. Full program will be revealed soon and will include workshops, talks by experts, introduction courses to all machines and a full material bank to build from.

What’s in it for you!

  • 1-month free access to Viadukten – Makers workshop in central Copenhagen
  • Free access to all materials needed for development and prototyping
  • Collaborate with a cross-disciplinary team and expand your network 
  • Directly contribute to improve everyday life for billions of people around the world

Partners: Maker (DK) & The Washing Machine Project (UK)

During the 1-week Refrigerator Development Sprint, the teams will have online meetings and dialogues with the UK team from The Refrigeration Project who are also behind The Washing Machine project, which is already implemented in the market. You can see the fully functional and market-launched washing machine in the video (credit: World Economic Forum) at the bottom of the page. 

The project is part of OPEN NEXT and has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement no. 869984
