Women like the improved efficiency and they make 0.5 to 2 kg of ember biochar a day. We've found that maize production improves significantly. If a family applies 1 kg of biochar to their field every day, that is the equivalent of about one tonne of CO2 mitigated per year by sequestering the carbon. With hundreds of millions of families cooking with open fires, the potential is enormous.<o:p></o:p></span></p></div><div><p class=MsoNormal><span style='font-size:12.0pt'><o:p> </o:p></span></p></div><div><p class=MsoNormal><span style='font-size:12.0pt'>We are making the training videos as small files in 3gp format so they can be shared between basic/feature phones using bluetooth.
