After building the first IBC digester and having it running for over 6 months ive noticed that improvements could be made, so in this build i have implemented them, not quite a step by step instructional but a guide if anyone wants to try the same, i will be updating about the design to see if it is actually indeed more practical and solves some issues - i think it will and am excited to see how it preforms, stay tuned

This video is about Craig Lecture - Types of Digesters

Anaerobic digestion is the process by which waste products can be converted into methane and biosolids. This technology has the potential to help reduce waste, produce energy, and produce a valuable end product, all while being carbon neutral. Steve Pugsley will discuss examples of this technology, where it has found success, and where it will be expanded in the coming decades. Pugsley has over 30 years of experience in sustainable urban and regional planning, zoning and economic development at the regional, county, city and township level. Prior to forming Midwest Renewable Energy, LLC, Mr. Pugsley was Director of Economic Development for a region in Michigan, And co-founder and Vice President of Procurement Technology International. Mr. Pugsley received his Bachelor of Science in Urban Planning from Iowa State University, is a Licensed Professional Community Planner (PCP), national registration in the American Institute Certified Planners (AICP) and is a graduate of the Seaside Institute Course on New Urbanism taught by Andres Duany and affiliates. Recorded at the Pierce Cedar Creek Institute during the 2014 Sustainability Conference, March 15, 2014.

Trials and tribulations of compressing biogas, had to film this over several days due to set backs and no time due to work but, we got there in the end. I apologise for the sound with all the rustling and pops etc, certainly not a cinematographer but i will see how i can rectify this. Stay tuned for more videos, subscribe, comment, im happy to answer questions where i can.

Here is a cob hot tub made from Earth right on my property in Petaluma. It takes about 4 hours for all the water in the tub to get to 104 degrees, but it is well worth the wait. It is sealed with lindseed oil, mineral spirits, and diatomaceous earth.

In this video I build a wood gas storage device that cleans and pressurizes the gas all in one! Thanks to my sponsor Squarespace you can make a great website easily! Check them out at: https://www.squarespace.com/nighthawk In case you missed it, here's my last video where I built the gassifier used in this video to make my gas: https://youtu.be/HQIW4dVVokE The wikipedia page on gas holders has some great visualizations and images of commercial gasometers: https://en.wikipedia.org/wiki/Gas_holder Thanks to all my Patrons for helping me make these videos! A special thanks to my top Patrons: Syniurge, Matthew Leitzke, TheBackyardScientist, Enzo Breda Lee, John Johnson, & Thibaud Peverelli! https://www.patreon.com/NightHawkProjects So what is wood gas good for? A lot of you have asked that question. The main point of wood gas is to turn a renewable fuel like wood/plant matter into a form that is compatible to be burned by modern technology like cars, generators, stoves, etc.. Wood gas is a fuel that can be made by anyone with simple equipment, and can run a gasoline engine with only minor modifications. The process I use in this video to make it produces a very clean result, but is not the most efficient way to make large quantities of gas for immediate burning. I'll be demonstrating other methods of wood gas production in future videos. Thanks for watching!
