APL began as an experiment in collaborative science and open source engineering.  In the almost 10 years since we started working with gasification through the GEK Project, APL has evolved into a small-scale biomass electrical generator manufacturer. We currently offer the low-cost, open-skid Power Pallet PP20, and the clean and quiet Power Cube PC20, and are actively developing our Power Container in 100-150 kW versions. Despite the patented and proprietary nature of our newest and most optimized gasifier designs, we are still working with GEK participants and gasifier enthusiasts to openly advance the science of gasification, as well as the engineering solutions to implement it meaningfully for today's users.

With this wiki we are trying to curate a comprehensive and growing knowledge base of everything we have learned about gasification and the resources we have uncovered in our work.  Here you will find detailed GEK gasifier building plans, gasifier configuration and operating tips, "how to" instructions for converting engines to wood gas, raw science, practical engineering, and many other topics of interest for Power Pallet users and gasifier geeks.  All topics are open for any contributions or edits you would like to offer. 

We are archiving our previous GEKforum, but will continue to host general discussion and debate about these topics in a new venue currently under design .  General information about the Power Pallets and APL is on the main info site  To get biweekly email updates on the project, click here and fill in the blanks.
