Brian. I have brought this matter up on several occasions regarding secondary exposure of thermal energy to the output gas. It seems to me that raising the temperature within a reaction chamber in the absence of oxygen and adding steam through a hollow carbon rod, the tip of which is producing a plasma can only improve the quality and quantity of usable gas, which will more than compensate for the electrical energy used.
There will be a considerable reduction in the flow of air for pyrolysis. In fact commercial plasma reactors do not require any air for combustion the oxygen is derived from steam. Use could be made of the hot exhaust stream from an ICE to torrify the "FUEL" in order to produce the required gas flow through such a reactor, thus claiming much of the thermal energy being wasted. the final product would also produce methanol not tar. I hope to obtain a high enough plasma temperature with the use of micro wave excitation, 2.4 Ghz radiation can travel through some types of refractory. this will cut costs considerably.

We had a number of physicists doing basic research, plus a lot of applied development work.
