Video Description

I just finished this gasifier and charcoal retort designed for off-grid electricity generation, automated with a custom Arduino system, and in this video I talk about the theory of gasification and pyrolysis, the design, and how I built it. Really excited about the potential for this to convert wood fuel into usable energy! Thanks to VITCAS for sponsoring this video!! Vitcas makes really great products, and if you’ve seen some of my previous videos you’ve definitely seen some of these before because I’ve been using Vitcas products for years and I highly recommend them!
