MonDie Posted May 31, 2015 Share Posted May 31, 2015 Apparently it charges a battery for night flight (9/17). Imagine if they were only flown during the day, and that extra energy was put back into the grid. Link to comment Share on other sites More sharing options...
dimreepr Posted June 1, 2015 Share Posted June 1, 2015 Apparently it charges a battery for night flight (9/17). Imagine if they were only flown during the day, and that extra energy was put back into the grid. It not only charges the batteries during sunlight hours but also gains height to take advantage of potential energy during the sunless hours. 1 Link to comment Share on other sites More sharing options...
overtone Posted June 3, 2015 Share Posted June 3, 2015 Turned around by bad weather, regrouping in Japan. http://www.bbc.com/news/science-environment-32993127 It's a six day flight, and they have reliable and sufficiently accurate weather forecasting for three days only - so there's a risk even with good initial conditions.
