When Anna Cain, a master’s student in Barcelona, was looking for inspiration for a school project, she was thinking about climate change and how technology might help.
There was a severe drought underway that “was really bad where we were living in Barcelona,” she recalls; “so I think it was just at the top of my mind.” What if, she and some friends wondered, you could get water directly from the air?
So that’s what her team devised: A lightweight jacket that condenses water from the humidity in the air all around, then sterilises it so it’s ready to drink. To make it, they borrowed some fancy technology they encountered on a study visit to CERN, the famed particle accelerator near Geneva. The result is a prototype to be on display at a conference on 2-3 July in Brussels, for an EU project that funded her visit. Working on the jacket, which they call PuffAIR, taught her a lot. “I loved the experience,” she says. “It was the highlight of my master’s experience.”
Hands-on tech training
Hers was one of many student tech projects organised since 2018 by the EU-funded ATTRACT project, in an unusual teaching experiment. More than 1,400 students from universities across Europe have taken part. The goal: To provide hands-on training in tech entrepreneurship, something Europe needs more of if it’s to compete in global tech markets. The main focus of the €55 million ATTRACT project is helping move “deep tech” innovations from lab to market, through a CERN-led consortium that includes seven big research institutions, a business organisation, and two universities: ESADE Business School in Barcelona and Aalto University in Helsinki. But studying innovation and teaching young entrepreneurs are also among ATTRACT’s objectives.
The curriculum for what ATTRACT calls its Academy involves a 12-week programme devised by Esade and Aalto with help from other universities. The students come from all disciplines: engineering, physics, business, finance, marketing, design – some 75 specialities in all. At their home universities, they attend classes on the key skills a flexible, multi-skilled innovator will need. Then they travel to meet the technology and its inventors — often to Geneva and CERN’s IdeaSquare innovation centre. In teams, they brainstorm on possible applications. Then they prototype, draft a business plan or develop marketing strategies.
In the PuffAIR project, the team was developing what it called “functional fashion to ensure survival in the climate crisis era.” At the time, Cain, a student at the Fabricademy textile and technology programme, had been reading a book about biomimicry – that is, turning to nature to find solutions to human problems. That led the team to look at an odd beetle that survives in the arid Namib Desert on the west coast of Africa by collecting water droplets on its bumpy back during morning fog and somehow getting the moisture to roll down into its mouth.
Between the beetle and the drought, Cain recalls, “I think we just put those two things together, and we thought, ‘let’s focus on water,’ because everybody’s talking about it and we are experiencing it every day where we are.” The project also drew some inspiration from the film, Dune, “just because of how sci-fi the project kind of is,” she says. Her team also included an Argentine student, Julia Rodriguez Heine, and Nico Garare of Spain, who contributed much to the jacket’s functional fashion design. “He had a lot of the vision for the physical prototype we were going to create,” Cain says.
In that prototype, a fan blows the surrounding air into the jacket made from a special fabric created on a computer-controlled knitting machine called Knitterate, which condenses the humidity into water that falls into a pouch. There, it is sterilised by a new carbon-based graphene system, under development by an ATTRACT R&D project called Megamorph, that generates ultraviolet light. A water-purity sensor double-checks it, ready for drinking. Cain recalls her favourite moments as the opportunities she had to make presentations about the jacket. That helped with her public speaking confidence and with the ability to translate her ideas into concrete thoughts. An American still living in Barcelona, she currently works on digital marketing for an organisation that promotes global standards for organically made textiles.
While the prototype could be a product one day, she says, “we didn’t really take a business approach from the start.” Instead, they wanted to make a statement: use the jacket as a launching point for a conversation or for ideas for design in the future. “It was an exploration of how we could be thinkers and dreamers.”
