Solar-powered boats are expanding in the Amazon rainforest, under an Indigenous-led initiative
Eight years after its launch, a solar-powered canoe initiative born in Ecuador’s Amazon is reshaping river transport far beyond its origins, reports Aimee Gabay.
The Kara Solar Foundation, led by Indigenous engineers and community leaders, has delivered 12 canoes to villages in Ecuador, Peru, Brazil, Suriname and even the Solomon Islands. Each vessel glides silently across rivers that once echoed with the noise and fumes of gasoline engines.
For many communities, rivers are the only roads. Solar boats spare them the cost of fuel while reducing pollution.
“[They] do not pollute the environment, especially for those who live near rivers,” said Ichinki Tentets Tanchim Federico, a leader of the Achuar community of Wayusentsa.
The boats also diminish pressure to build roads, which often accelerate deforestation and the spread of mining and livestock.
The first canoe, Tapiatpia, proved the concept in 2017 when it traveled 1,800 kilometers across Amazonian rivers. Since then, Kara Solar has paired its boats with solar recharge stations that double as community energy hubs. Local residents are trained to operate and repair the systems themselves.
“Kara Solar ensures that technical knowledge is cultivated within the communities,” says Nantu Canelos, the foundation’s executive director.
Ambitions run high: By 2030, the group aims to support 10,000 solar canoes across the Amazon Basin and create a network of Indigenous-run recharge stations. Yet financing remains elusive.
“Projects like this…are not attractive for traditional investment because they are not designed to obtain large gains quickly,” Canelos said.
Still, in regions where infrastructure is sparse, these solar vessels offer a rare chance to chart a different future—quietly, cleanly, and on local terms.
