your take on MNM moves from a misapprehension - MNM is not a coal technology company, MNM is a diversified resources junior.
one of MNM's many highly promising projects is a likely JV with exergen about using THEIR brown coal tech at BM.
exergen are the coal tech rival you want to compare ESI to, not MNM.
I have looked at both techs, and more importantly, the identity of those who have invested in each tech and stand behind them. as you seem very keen on ESI v MNM comparisons - why don't you do that exercise over at the ESI thread?
