Karve & Gasification Colleagues<br><br>Is there any documentation of this village scale electrification project? Is the project currently running?<br><br>I have read the IISc Papers on the Hosahalli Village project - but that was more than 20 years ago.<br><br>I have been working on an experimental spark ignition conversion of the Lister type single cylinder engine - so that it can be run either on woodgas or diesel/biodiesel.<br><br>The intention is a diesel start-up (for convenience) and then a rapid switch over to woodgas, when the gasifier is up to temperature. This minimises the amount of diesel needed over the whole run time - yet provides the convenience of a quick start-up cycle.<br><br>We have retained the 17:1 compression ratio of the Lister engine - and are currently re-tracing the work - initially done in India to prove that woodgas can be used at these compression ratios - without pre-detonation (knock). So far, the results look promising and we have achieved between 2500 and 3000 electrical watts from the 6HP Lister engine running in this mode. <br><br>The project has been ongoing for some time now - and we hope that it will result in a spark ignition kit being offered for owners of small diesels. The Lister type engines are particularly suitable for conversion - but we hope that other small diesels - such as Kirloskar are also fairly easily converted - with the addition of the sparkplug.<br><br>This work is being undertaken at All Power Labs in Berkeley, California - and was recently demonstrated at a Weekend Workshop earlier this month.<br><br><br><br>Ken Boak<br><br>Principal Electronic Engineer<br>All Power Labs<br>Berkeley <br>CA 94710<br><br>510 684 2640<br><br><o:p></o:p></p></div></div></body></html>
