This project aims to introduce and promote the cultivation of spirulina in low-income neighborhoods in Bogotá. The initiative targets combating malnutrition, creating new income opportunities, and enhancing environmental sustainability within vulnerable communities.

Its focus is on designing, manufacturing and distributing low-cost, energy-efficient biomass stoves that can reduce biomass fuel consumption, lower the smoke inhalation and carbon emissions. The project also includes developing clean solid biomass fuel with wood derived from invasive bush trees, rampant across Botswana’s farmlands.

It is the first step to a new design of bladeless turbines with hydrofoils. Their streamlined design reduces the impact on marine life by eliminating rotating blades and enhances efficiency in energy conversion. Emilia suggests that hydrofoils operate by harnessing lift generated from water flow, allowing them to capture energy with reduced drag and increased effectiveness.

This is a revolutionary integrated communication system designed to provide early flood warnings. The system includes a telemetry buoy, a signal tower, and a solar-powered alarm system. These components work seamlessly together to monitor water levels and deliver timely alerts to high-risk areas.
