<strong>Micro</strong>-<strong><strong>gas</strong>ification</strong>: <strong>Cooking</strong> <strong>with</strong> <strong>gas</strong> <strong>from</strong> dry <strong>biomass</strong><br />
II) Lever-presses (wet pulp, low-moderate pressure)<br />
Levers are good tools to create elevated pressure just <strong>with</strong> the input of human power.<br />
Longer or multi-compound levers increase the achievable pressures. Levers are faster to<br />
use than screw platens or hydraulic jacks.<br />
There is a multitude of different lever presses out there. This section showcases only a selected<br />
sample of models which are easy to replicate or where plans for replication are<br />
available.<br />
a) Paper-brick Maker<br />
<strong>from</strong> Newdawnengineering<br />
at ca. 300 ZAR<br />
Makes a 230x90mm fuel<br />
brick out of waste paper<br />
which can be mixed <strong>with</strong><br />
other combustible fuels<br />
like wood chips, grass or coal dust. Paper is a very good binder and<br />
should be used in combination <strong>with</strong> any other waste fuel that is<br />
available. Pressure generated by two small levers.<br />
Ideal for decentralised small-scale production. More details at<br />

b) Wooden presses by Leland Hite<br />
A very simple and low-cost <strong>biomass</strong> fuel briquette press made <strong>from</strong> wood can be found on<br />
http://www.youtube.com/watch?v=Mt0QQe6Eetw. The very instructional video showcases<br />
simple yet powerful and versatile versions of wooden single-lever and multi-compound lever<br />
briquette presses, which can produce square or round <strong>biomass</strong> briquettes at a speed of<br />
less than 1 minute per briquette. Measured drawings in inches or metric measurements in<br />
english and french language (incl. link to the video) can be found on<br />
