Claim:
1. A method to convert natural gas to liquid fuels and to liquid natural gas (LNG), the method comprising: providing a heat exchanger with heat exchanger plates having surfaces; increasing surface area to volume ratios on the surfaces of the heat exchanger plates by providing nanosecond or femtosecond pulse laser machined structures on surfaces of the heat exchanger plates; exposing natural gas to the surfaces of the heat exchanger plates; cooling the natural gas through heat transfer from exposing the natural gas to the surfaces of the heat exchanger having the nanosecond or femtosecond pulse laser machined structures; and converting the natural gas to the liquid fuels and to the liquid natural gas (LNG).
