Zephyr UAS smashes its own endurance record, may still be up there

The remarkable Zephyr is a stratospheric UAV designed to fly ultra-long endurance missions acting as a solar-powered observation and comms platform. In its latest test, it sailed past its old endurance record two weeks ago, and may still be up there.Co… Continue reading Zephyr UAS smashes its own endurance record, may still be up there

Another hydrogen transport powder emerges, promising double the density

Stir this silicon-based powder into water, and hydrogen will bubble out, ready for immediate use. Hong Kong company EPRO Advance Technology (EAT) says its Si+ powder offers an instant end to the difficulties of shipping and storing green energy.Continu… Continue reading Another hydrogen transport powder emerges, promising double the density

World’s first laser-controlled drone easily evades countermeasures

Counter-drone systems typically attack a UAV’s radio control or GPS systems, disabling pilot control as well as pre-programmed missions. But British defense tech company QinetiQ has now demonstrated a laser-controlled drone these systems can’t stop.Con… Continue reading World’s first laser-controlled drone easily evades countermeasures

All-in-one solar tower produces jet fuel from CO2, water and sunlight

Taking carbon dioxide, water and sunlight as its only inputs, this solar thermal tower in Spain produces carbon-neutral, sustainable versions of diesel and jet fuel. Built and tested by researchers at ETH Zurich, it’s a promising clean fuel project.Con… Continue reading All-in-one solar tower produces jet fuel from CO2, water and sunlight

Mechanochemical breakthrough unlocks cheap, safe, powdered hydrogen

Australian scientists say they’ve made a “eureka moment” breakthrough in gas separation and storage that could radically reduce energy use in the petrochemical industry, while making hydrogen much easier and safer to store and transport in a powder.Con… Continue reading Mechanochemical breakthrough unlocks cheap, safe, powdered hydrogen

Eve ditches its pretty canard eVTOL design for something simpler

Embraer spinoff Eve has changed tack on its eVTOL aircraft design, unveiling a new single-wing lift and cruise design, as well as a refreshingly utilitarian-looking mockup of its passenger cabin, at this week’s Farnborough air show outside London.Conti… Continue reading Eve ditches its pretty canard eVTOL design for something simpler

AGV Tourmodular flip-face helmet has zero dynamic weight on the highway
