When the 56-megawatt Gala Solar Power Plant that just broke ground in Cook County, Oregon, is completed at the end of 2017, it will be the state’s largest operating solar farm. But the project is ...

A high-altitude unmanned-aerial-vehicle prototype, powered by solar panels and batteries, performs functions commonly attributed to spacecraft flying in low Earth orbits. HAPS is happening. UAVOS Inc.

An electric-motor driven UAV (unmanned aerial vehicle) recently completed a 48-hr nonstop test flight using only solar energy. The two-day test demonstrated the feasibility of sustainable flight using ...

Have you ever imagined a drone that could fly indefinitely, powered only by the sun? It sounds like something out of a sci-fi movie, but it’s now a reality. By harnessing the power of renewable energy ...

When the US Naval Research Laboratory (NRL) selected Alta Devices, a Hanergy Company, as the solar solution for the prototype Hybrid Tiger UAV (Unmanned Aerial Vehicle) Project, I decided to see what ...

Imagine attempting to construct and maintain a new, massive solar installation using only on-the-ground resources. The time, effort and guesswork required for each step – from scoping out potential ...

While SolAero provided technical data for the Solar Performance Index calculations in an earlier piece, What the US Navy’s solar drones tell us about thin-film solar’s potential, their responses to my ...

Sam Stranks and his team at the University of Cambridge hope they’re on the brink of a revolution in solar technology. For decades, silicon has been the most popular material used to make solar power ...

No matter how cool, versatile, or sophisticated drones might be, they all suffer from the same problem: Limited flight time. They can only do so much on a single charge; you either have to wait until ...

These are exciting times for the solar aircraft industry. Airbus and Boeing have carried out high-profile launches, as have technology giants Facebook and Google – but not all still in the race. So ...
