Black plastic pipes distribute biogas to eight homes in the rural town of La Macuca in Cuba, thanks to engineer Alexander López Savran
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.
“A new biodigester has been designed to obtain pressure, which means that biogas can be distributed more than five kilometres away without the need for a compressor or blower.
That is where the innovation lies,” the engineer, who lives in the city of Cabaiguán, capital of the municipality of the same name, where La Macuca is located, in the central province of Santi Spíritus, told IPS.
