[Stoves] ARTI Biogas vs. conventional biogas

[Crispin Pemberton-Pigott]

Dear Dr AD

Thanks for the comparative review.  It seems there are certain opinions
extant not supported by facts.  Thank you for providing numbers to go with
your statements. I have previously seen the claim before that the total
energy output from a conventional biogas plant is better than burning the
dung. Perhaps (excusing them) they are looking at the total energy in the
effluent, not two different ways of generating a fire: gas v.s.
dung-as-fuel.

I certainly see merit in both systems and agree that populations without
access to cattle or people in tight urban spaces would be hard pressed to
use a conventional below ground system.  Often there is no ground!

I find it extraordinary to hear that the Ministry of New and Renewable
Energy Sources has not made an official visit to establish for themselves
the veracity of claims and performance.  I can't find an excuse for that.

Regards
Crispin
