"Money to me is freedom, and freedom is essential. Money allows me to say that I will now devote my life to being me, rather than putting on my shoes and tie, and going to an office every day."
- Robert Silverberg

Pocket Gravity Nullifier  
  Personal device stops gravity's effect.  

He looked upward as he attempted to visualize more fully the frightfulness of the whole tragedy and gasped in startled consternation. Like feathers that had been left behind after the denser matter had separated and fallen away, he saw men floating gently toward the ground. Several touched the earth lightly and came hurrying toward the rescue party while others were yet high in the air...

For a few minutes the captain was not occupied and Addison asked him concerning the men who floated in the air. “They are using pocket gravity nullifiers. They are an outgrowth of the old type parachute,” the commander answered calmly despite his anxiety. “And see, they are using nullifiers to clear away the wreckage.”
