Solar Community Radio

Barcelona, 2026

What happens when the power goes out?

Last year’s electricity cut in Spain reminded us how fragile our cities can be, and that resilience isn’t just about infrastructure, it’s also about community and shared tools.

We invited a group of students from IED to think about this question: What can we build, with limited means, to stay connected during a power cut?

The result is this mobile, solar-powered, off-grid community radio, co-designed and built during a short workshop: a place to charge devices when the sun is out, stay informed, and gather.

We hosted this one-week workshop at IED Design School in Barcelona in February 2026.
