Solar-powered ambulance unveiled by Dutch students to serve remote areas

Students from Eindhoven University of Technology in the Netherlands have developed the "Stella Juba," a groundbreaking solar-powered ambulance designed to provide medical services in remote areas lacking reliable electricity. This innovative vehicle aims to function as a mobile clinic, bridging the gap in healthcare access for underserved populations.

The Stella Juba boasts an impressive range, capable of traveling up to 715 kilometers on solar power alone on a clear day, with a top speed of 120 km/h. Its design prioritizes efficiency and durability, incorporating high-efficiency "all-back-contact" solar cells from AIKO, which can capture more sunlight even on cloudy days. The vehicle's structure utilizes lightweight carbon fiber composites, common in aerospace, reducing its weight to approximately 1350 kg, significantly less than conventional ambulances.

To ensure continuous operation, the Stella Juba is equipped with a battery system on its roof, allowing medical equipment to function during the night or extended periods of bad weather. The electrical systems are ingeniously separated: power for driving and power for the medical bay are distinct. This ensures that even if the driving power is depleted, the remaining battery power prioritizes the medical equipment, enabling continued emergency care.

Inside, the ambulance is configured as a self-contained treatment room, with climate control for temperature and humidity. It is outfitted with essential medical devices, including portable X-ray equipment, ultrasound for prenatal check-ups, rapid malaria diagnostic tools, and an automated external defibrillator (AED). A high-performance cooling system is also included to safely store vaccines and medications in hot climates.

The Stella Juba is currently a prototype, with plans for real-world testing in Kenya in collaboration with Amref Health Africa. This field trial will assess the vehicle's performance, durability, and overall effectiveness in challenging terrains and actual medical scenarios, providing valuable data on the potential of solar-powered mobile clinics in regions with limited infrastructure.
