Volunteers in Argentina are working to turn recycled materials into solar power stations for marginalized communities.
Activists say the homemade system they are building is ingenious, but simple, and could easily be replicated in other communities where the sun shines. They bring leftover soda cans, plastic bottles, and milk cartons to recycle. Volunteers paint the pipes black to soak up heat from the sun.
This way, the “solar collector” keeps water hot without using electricity or gas. The group has assembled 36 solar panels since 2014. It offers workshop for those keen to turn materials into solar-powered heaters. Volunteers can learn about recycling for 40 dollars.
