1. A drilling device having special utility for drilling at great depths in the earth'"'"'s surface, said drilling device comprising:

  • a tubular drilling lance having a top end and a bottom end, said drilling lance adapted to being lowered to great depths in the surface of the earth and being raised therefrom;

    an energy generating system disposed in said lance, said energy generating system being characterized by;

    a. a fluid vaporizing system, said fluid vaporizing system comprising;

    i. at least one fuel container and fuel contained therein, said fuel container is a collapsable bellow-like container configured such that external pressure on said container provides a positive pressure on said fuel contained therein,ii. a reaction chamber coupled to said fuel container,iii. a heat exchanger coupled to said reaction chamber such that heat from said chamber is transferred to said heat exchanger,iv. vaporizable fluid communicating with said heat exchanger whereby said fluid is caused to vaporize by said heat, andv. condenser means directly coupled to said heat exchanger such that said fluid is selectively cooled and returned to said heat exchanger without loss of said fluid; and

    b. a turbine coupled to said vaporizing system by a closed fluid circuit such that said fluid is coupled from said heat exchanger to said turbine and further coupled from said turbine to said condenser means; and

    drilling means disposed adjacent to and extending outwardly from said bottom end of said drilling lance, said drilling means coupled to said turbine such that activation of said turbine by said fluid vaporizing system causes activation of said drilling means.
