Re: [semi OT, FH] Mine detecting plants

As someone who works in this field I'm rather skeptical about all these 
lab grown ideas.
As the article states they do not know how much gas the plant needs to 
turn red. I would imagine that a waterproofed (and thus sealed) mine 
would release very high quantities of that gas. And what other sources 
can produce the same gas? There must be other nitrate based stuff in the

ground that might give of the same gas.
Would like to see the chemical formula of the special fertilizer too. If

there's nitrogen in it somwhere....

Nothing beats a good detector, a fresh set of batteries and a patient 
and methodical approach of the problem.
