Fred, Stan and I are working like crazy on testing and refining the Gen2.1 cookstove. Thus far we have made and tested four stoves all with incremental design improvements. Sadly, we can not yet show any photos or images as the intellectual Property protections are not in place yet.
However, With our testing and minor modifications (will be easy and affordable to incorporate into production). We have greatly improved the usability, cooking efficiency and reduced the material volumes.
We are still on schedule for our launch in late Jan 2018 in Chiapas, Oaxaca and San Luis Potosi.
