two ag-related questions

[Gaithermj@aol.com]

1.  Has anyone heard of utilizing waste steam for a greenhouse?  don't need 
the energy, just looking for warmth/humidity.  Don't know how far the steam 
could travel before losing the warmth.  Apparently this is done in the 
Netherlands??

2.   Any suggestions on capturing methane which is escaping from a small 
farm's
irrigation well?

thanks!!
