 Nanotechnology might thus help to reduce the size of equipment and thereby decrease fuel-consumption required to get it airborne.Hang gliders may be able to halve their weight while increasing their strength and toughness through the use of nanotech materials.Nanotech is lowering the mass of supercapacitors that will increasingly be used to give power to assistive electrical motors for launching hang gliders off flatland to thermal-chasing altitudes.
