Solar panel-equipped ski helmet uses sunlight to power its communications system

Solar panel-equipped ski helmet uses sunlight to power its communications system: "It looks like the skiers' communications systems from Buhel and Recon could soon be in for some solar-powered competition. Working with German tech company TEXSYS and the Technische Universität Berlin, researchers from the Fraunhofer Institute for Reliability and Microintegration have developed a communications module that can be integrated directly into a ski helmet."

ASV hulls would dramatically improve ship efficiency by riding on a cushion of air

ASV hulls would dramatically improve ship efficiency by riding on a cushion of air: "A European project is developing new Air Support Vessel (ASV) hull designs that allow watercraft to ride on a cushion of air to greatly reduce friction between the hull and the water, resulting in more hull speed for less power than conventional designs."
