    Default Solar balloons to get a better yield


    This concept would allow to capture sunlight half of the year, instead of 15% of the time.

    Here’s how it works: the case is transported to a disaster zone. You remove the balloon from the drawer and open it up on the ground so it can start collecting solar power immediately. Now add water. Zephyr has an electrolyzer on board that uses nine liters of water to produce hydrogen to inflate the balloon, which attaches to the base with the cable.

    The team partnered with the Institute for Research and Development of Photovoltaic Energy (IRDEP) to develop the balloon. Constructed of a hydrogen plastic sail, it’s covered with a thin film made of copper, indium, gallium and selenide (CIGS) that absorbs solar energy. The balloon can fly as high as 165 feet and has a steering mechanism, which ensures it receives maximum exposure to the sun.
