A Deliberately Engineered Ecosystem

A 150–200MW geothermal power plant — using XGS solid-state closed-loop technology — provides the energy backbone for the entire mainland district. Unlike conventional geothermal, the XGS approach eliminates the risk of induced seismicity and contamination of underground aquifers, making it compatible with the programme's ecological standards. Waste heat from the geothermal process feeds the brine crystallisation units directly, eliminating the need for separate industrial boilers.

The material logic of the mainland district is deliberate at every step. Agricultural waste from the 35-hectare greenhouse operation becomes feedstock for HVO biofuel production. CO₂ captured from industrial processing is piped back to the greenhouses for crop enrichment. Water recycling closes the loop between the desalination plant, the data centre cooling towers, and agricultural irrigation. These are not aspirational goals — they are engineered dependencies that make each operation more profitable and more sustainable when operating together.

The Delta Aerospace seaplane manufacturing facility is not merely an export industry — it is a transport enabler. Aircraft produced in the mainland zone connect the mainland district with Siberut Island, the Mentawai archipelago, and regional destinations. The 50-hectare logistics hub integrates ferry terminals, seaplane taxi maintenance, warehousing, and customs clearance into a single coordinated facility. Agricultural produce is distributed through this hub, reducing cold-chain losses and connecting local production to regional markets.
