Marine Technology

The Vanguard is a precursor to the Sentinel system, shown in this render. DEEP says Sentinel – a modular, reconfigurable underwater habitat – will enable six people to stay at depths of 200 meters (656 feet) for 28 days. DEEP wants to “make humans aquatic.”

Can these underwater habitats ‘make humans aquatic’?

US company Calcarea is developing technology to removw carbon dioxide from the exhaust of cargo ships. Pictured is a prototype reactor at the Port of Los Angeles. <strong>Scroll through the gallery to see more innovations that are helping to make transport greener.</strong>

MIT Self-Assembly lab and the Maldivian organization Invena are working to create underwater systems that can harness wave energy to help rebuild coastlines or even build new islands. The organizations have completed nine field experiments in the Maldives, the world’s lowest-lying country.<strong> Scroll through the gallery to see their work.</strong>

Stella Terra, here on a roadtrip through Marocco, is the world's first off-road solar-powered car. Developed by the student team Solar Team Eindhoven, Stella Terra is the first solar car that is robust and efficient enough to go off the beaten path. With this, the students take another step towards a sustainable future, inspiring both society and the current market to accelerate the transition to a sustainable future.
