1. An alternative heat source for an internal combustion engine comprising:
an elongated compartment with a first end and a second end;
a directed energy device with a focal point within the first end of the compartment, the directed energy device capable of sending a pulse of photonic energy to the focal point;
a computer processor configured to control the directed energy device;
an intake into the first end of the elongated compartment, the intake allowing for the entry of a gas into the first end of the elongated compartment;
an exhaust from the first end of the elongated compartment, the exhaust allowing for the exit of the gas from the first end of the elongated compartment;
a piston capable of moving within the elongated compartment between the first and second ends; and
where the pulse of photonic energy at the focal point is capable of heating the gas and causing a corresponding expansion of the gas in the elongated compartment, driving the piston toward the second end of the elongated compartment.
