baobab-inspired floating waterfall power plant generates renewable energy off madagascar
circular ocean-powered complex reimagines energy production
Designed as an entry for the prestigious Jacques Rougerie Foundation competition, ‘Baobab Waterfall’ project by Ahmad Eghtesad is a conceptual mixed-use infrastructure proposed for the coastline of Madagascar. The island is rich in natural resources and unique biodiversity, yet severe energy shortages leave a vast majority of the population without electricity. This energy crisis contributes directly to economic hardship and rising crime rates, leading to severely overcrowded correctional facilities. This project seeks to address these interconnected crises through a radical architectural intervention that turns a societal challenge into a profound economic opportunity.
The core structural form of the complex is heavily inspired by the native Baobab tree, a national symbol of Madagascar known for its ability to store water and sustain life in the harshest environments. Mimicking the tree’s thick trunk and sprawling, protective canopy, the central building functions as a multi-story administrative and living hub rising high above the tropical landscape.
The floating design proposes a massive and continuous system of deep-ocean waterfalls, generating renewable electricity on a scale akin to natural wonders. By engineering a colossal, circular marine infrastructure, ocean water is funneled directly into subterranean turbines deep below the surface. This dual-function structure acts simultaneously as a highly efficient green power plant and a monument. The sweeping cascades protect a lush, palm-fringed central sanctuary from the open sea, creating a spectacular landmark designed to draw global eco-tourism.

greenhouses integrate cultivation, learning, and community life
Initially envisioned by designer Ahmad Eghtesad as a rehabilitative facility, the architecture encourages constructive interaction between residents and the surrounding environment. The central ‘trunk’ features multi-level, transparent greenhouses where inmates participate in modern agricultural training programs. By cultivating crops and trading goods along sunlit pedestrian pathways, they foster vital skills for a healthy economic life upon release. Beneath the ocean surface, a massive, pressure-resistant glass dome bridges the gap between human innovation and marine biology, giving residents a direct view into a thriving coral reef ecosystem while leaving migrating marine life undisturbed. As crime rates decrease and society heals, the modular complex is designed to seamlessly transition into a public eco-resort and green energy hub, securing a prosperous, self-sustaining future for the island.
