Tech Scrape

Nighttime flight is an important milestone–but solar power is unlikely to transform aviation. Swiss researchers yesterday marked a major milestone in the development of a solar-powered, single-pilot aircraft that they hope will eventually circumnavigate the globe. They kept their craft aloft through an entire night on stored solar energy.

A new process could allow Air Force jets to run exclusively on domestically produced biomass and coal.

The aircraft will one day be used to circumnavigate the globe.
