Local Innovation Facilitates Solidarity-Based Biogas Networks in Cuba
Black plastic pipes, readily available on the mainly empty shelves of Cuba’s shops, distribute biogas to homes in the rural town of La Macuca, buried under the ground or running through the grass and stones in people’s yards.
The strong blue flame in the kitchens of the eight homes supplied by producer Yuniel Pons is thanks to engineer Alexander López Savran, who innovated the standard fixed-dome biodigester to create distribution networks with the few basic materials available in this Caribbean island nation.
