[Gasification] Moisture, Humidity & Inlet Air

[jim mason]

yes and wow.  that is quite fascinating greg.  i agree.  it would not be
difficult to have a cycling between two dessicant air intake vessels, with
gasifier/exhaust heat to cook the water back out.

it will be interesting to see the volumes needed to meaninfully reduce air
moisture.

someone with better quantative chemistry skills than me should do the
numbers of relative ration of water coming from air vs water in the fuel.
drying the air in wet atmospheres might prove a very relevant intervention.
