Who we are

Climate technology
for the real classroom.

From Barcelona we design real sensors, data platforms and curriculum materials so that any teacher can teach climate change with the classroom's own measurements, not with charts from the internet.

Our Mission

We turn climate change into measurable, actionable learning.

At POWAR STEAM we bring climate science into the classroom with IoT hardware, educational software and teaching resources that reduce teachers' preparation time and give students real data to investigate, compare and draw their own conclusions.

Our Vision

That every school can measure the climate around it, understand the data and act on it, with the same tools a researcher uses, but designed for the classroom from day one.

Pablo Zuloaga · Founder of POWAR STEAM

POWAR began as a question for farmers: how to test today the climate their fields will have tomorrow. That same question, taken into the classroom, is what gives meaning to everything we do today: students measuring their own climate and understanding it with real data.

Our story

From a wooden box to classrooms across Europe

The idea

During the Master in Design for Emergent Futures (IaaC and Elisava), Pablo Zuloaga asks himself how to help smallholder farmers prepare for the climate to come. That is how POWAR was born: Plant Observatory of Weather Adaptability for Resilience.

The first prototype

At IaaC and Fab Lab Barcelona the first box is built: it downloads the live weather of any city and recreates it inside, to see how a plant would grow in another climate.

  • Fab Schools (Fab Foundation) award for best STEAM project, with the P.OW.A.R. lesson.

From the lab to the countryside

With the support of the Diputació de Barcelona and Rupit Town Council, a second prototype is built, designed for rural areas.

  • Shown at the Rupit Rural Innovation Fair and at Smart City Expo World Congress, with FarmLab Rupit.
  • Selected by the European accelerator FoodSHIFT 2030.
  • Utility model registered.

A connected simulator and the first P-Bit

The third simulator prototype arrives, with its own board and a web platform to choose the climate. Alongside it, the first version of the P-Bit is born: a small environmental computer for measuring in the classroom.

From Barcelona to the world

The P-Bit v2 is designed together with teachers and tested in three schools. And POWAR goes out to show what it does:

  • Invited to Maker Faire Lisbon.
  • Speakers at the FoodSHIFT Summer School in Athens.
  • Exhibitors at Fixing the Futures, in Barcelona.
  • Best Exhibit award at Maker Faire Shenzhen, with the support of Seeed Studio.
  • Speakers at the Hackster.io Impact Summit and participants in the Industrial Tech programme by CIM UPC and Stage2.

The P-Bit v3 enters the classroom

The team comes together and the P-Bit v3 reaches schools: students in Spain and Croatia use it in real projects, such as the mushroom-growing project at Escola Joan Miró.

  • Winning startup at EIT Jumpstarter (New European Bauhaus category).
  • Pre-incubated and finalists at Barcelona Activa.
  • Among the 20 best projects in the Government of Catalonia's PRIME programme, in two editions.
  • Our prototype inspired the MiTequiobox, a sensor box for farmers in Calpan (Mexico), at the Fab City Challenge Mexico 2024.

The company is founded

POWAR STEAM is incorporated as a company. We train teachers and work with students in Croatia within an Erasmus+ project, and prepare the school pilot of the new simulator version.

  • Project selected by SEK Labs (EdTech accelerator).
  • Exhibitors at 4YFN (Mobile World Congress).
  • Pre-selected as a UOC spin-off.

Our Values

The principles behind every design, business and impact decision we make.

Sustainability

Every product we design has to help a student understand their climate with their own data, not with abstractions.

Innovation

We use IoT sensors and climate simulators because classroom questions deserve tools that connect real science and sustainability.

Open Source

We believe in collaboration and shared knowledge. POWAR STEAM promotes Open Source so that teachers and developers can adapt the resources as much as they need.

Accessibility

Every teacher deserves effective, easy-to-use teaching resources. Our products include curriculum-aligned learning activities that require no advanced technical knowledge.

Collaboration

We work with institutions, educators and organisations to build a support ecosystem that boosts the impact of climate education worldwide.
