The Holey Roket Stove and BioChar Project

Objectives of the Project

This project hopes to

– Determine the technical performance of the stove prototype.
– Determine its char making properties
– Determine the user responsiveness of the design.
– Generate lessons and renovate accordingly.
– Solicit support for further improvements and eventually manufacturing.

Features of the stove

– It will allow continuous cooking.
– It will allow better flame control.
– It will eliminate risk of handling hot char.
– The stove will allow more types of fuel.
– It can be produced with less cost.
– It will stimulate employment and promote social inclusion.
– Allow longer stove life.

The stove is still in a development stage, but we believe it has a great potential!
