These make extinguishers and chutes heavy and hard to use, adding weight and wasting fuel in aircraft. But Russian and Dutch scientists have developed a system that replaces the hefty nitrogen tanks. It weighs half as much and occupies half the volume, says Ronald van den Berg of the Dutch research lab, TNO,
