[Gasification] Some ideas to work on!

First of all, carbon not only soaks up micro waves, it heats up all
that is within its vicinity while in the presence of a micro wave
field, 

We hope you are not telling us,? it is quite impossible to construct a tuned "tank" within which to process our hot smoke?
You are aware of course that the micro waves can be retained in a "perforated" enclosure,? provided the holes don't exceed the wave length,wave guides can be plumbed for this purpose.

The temperature and composition of the gasses leaving the Char zone of our gasifier need raising to a higher level, to the temperature at which water will crack and combine with free carbon and also turn CO 2 into CO.with the release of yet more hydrogen.

The extra heat to overcome the endothermic process which makes water
gas, will be provided by an electrically produced plasma, Micro wave or
some other means in the absence of free oxygen.

If this is possible,and it is quite obvious you don't.
The problem of
dirty gas which has plagued gas makers since day one. will be
eliminated.

I expect every one is familiar with Mr Rieds metal melting domestic micro wave oven, just in case:


http://home.c2i.net/metaphor/mvpage.html .is the web site. 

This article describes his research. and the use of various methods of utilizing a domestic micro wave oven? to melt metals.

There is another guy who sets fire to sea water with a magnetron: but I have not had sight of his patent yet.

A plasma could be produced in the required area of our gas making plant by other means,but I feel this idea has merit and I will pursue it.

We have had designs which include? a two stage? plant . one to make the
fuel, which is then able to feed its product into a second unit, capable
of producing reasonably clean gas.
I am looking for something from today's technology that was needed yesterday.

Note that the microwaves in a microwave oven are "tuned" to match the 
vibrational frequency of the water molecule, and would not excite carbon, 
CO, H2 or any other molecule except water.  Solid carbon, as an electrical 
conductor, will absorb microwaves and absorb heat via circulating eddy 
currents, the way any metal object will in a microwave oven.  Presumably a 
plasma, also being electrically conductive, would as well.  However, gaseous 
carbon, CO, H2 and other gasifier outputs would not.
