[Stoves] Report #1 from ETHOS meeting

Mon Jan 26 13:13:57 CST 2015

Dear Crispin -

Could you share more information about this and why it there has been no
net fuel savings?

''Marc Park pointed out at ETHOS that in a village studied where all users
had an 'improved stove and used them religiously' there was no net fuel
saving.''

Very interested to hear your thoughts,

Teddy
