1. A method for producing carbon nanostructures, the method including:

  • (a) injecting acetylene into a reactant liquid;

    (b) maintaining the acetylene molecules in contact with the reactant liquid for a period of time sufficient to liberate a respective carbon ion from at least some of the acetylene molecules, and place the liberated carbon ions in an excited state;

    (c) enabling the liberated carbon ions in the excited state to traverse a surface of the reactant liquid and enter a collection area; and

    (d) providing one or more collection surfaces in the collection area to collect carbon nanostructures.
