     [RWL:   I had not seen this video before.  It is fairly new and I recommend it, although very little on biochar.  But Josiah's observations about seeing biochar used as a common practice is very important.  I have not previously seen that in print for Peru. 
	I have been to some of the places shown (Machu Pichu? and others much more remote closer to the ocean) and kick myself for not having looked for what Josiah saw and has here reported on.

	Josiah is one of the best spokespersons we have for biochar.  Look at his TED talk at   http://www.youtube.com/watch?v=SWbomZJn83U.
That one focuses on improved ag performance.  Look at the way he produces char at:

which I got to from Kelpie Wilson’s nice site:  http://www.greenyourhead.com/kilns/

	[RWL:  And we are learning how to do it over again with greater efficiency with any cook able to earn money (zero cost for cooking) by making char on TLUDs and similar stoves.

	[RWL:   Hope this is not a trick question - but “Yes”.  I can’t see why you ask.      Ron]
