The Complete Biogas Handbook – The Bio Methane Bible

We have been involved with Bio Methane digestion for about a decade or so, and we were honored to work with Al Rutan, The Methane Man for several years before he died. By no means am I a methane guru, but I have friends who are. I’d like to introduce “The Complete Biogas Handbook“, by David William House.


Reviews by Experts

“Hoo BOY, is it complete! …So lots of the numbers you need are here, and many hard-won tips are shown from often bitter experience.… The book’s main value is in showing how to do things that have been glossed over or ignored in other books, such as burning methane in a gasoline engine. If biogas interests you enough to consider making a generator, this book is your next assignment.”

J. Baldwin, The Next Whole Earth Catalog

“This readable book provides a comprehensive survey of the theory and practice of biogas production. The author discusses the scientific terms used, the substances (such as manure and plant matter) which can produce biogas, and various types of biogas generators.”

Mother Earth News

“House… has written a thorough introduction not only to biogas plants but to the ancillary problems such as gas utilization, engine/generator interfacing, refrigeration, and similar topics.”

Alternative Sources of Energy

“…bringing together material of importance that has hitherto been spread far and wide.”

Steve Smyser, Organic Gardening

“I ordered your book several months ago and have been very excited to find one single source with so much great information in it. It is, without a doubt, the best book out there on small digesters! Bravo, sir! I am currently writing a fact-sheet on micro-digesters and their potential for sustainable farms in the U.S., and your book will be at the top of the recommended reading section.”

Rich Dana, an Energy Specialist working for the National Center for Appropriate Technology

Trojan Battery Configuration Calculator

TRJN_BatterySizingCalculatorSS (2)A few years ago I designed a online battery load calculator, but Trojan (one of our favorite off grid battery manufacturers) came out with a good configuration tool. This calculator is a tool to help you determine the model and quantity of Trojan batteries needed for your renewable energy or backup power system. The calculator recommends batteries based on your inputs and the results are ranked according to cycle life performance.

Lloyd Godson – Aquanaut


My name is Lloyd Godson (; the 2007 Australian
Geographic Adventurer of the Year for living underwater in my BioSUB. The BioSUB was the world’s first self-sufficient underwater habitat that utilised a plant based life support system. You can read an article about it which appeared in the Australian Geographic magazine here:

In 2010, I spent two weeks living underwater in the Atlantis by Sealife Aquarium in LEGOLAND Germany while setting a new Guinness World Records for generating the most electricity by human power underwater. I have also pedalled a human-powered submarine through the Greek Islands!

I am currently living in Port Macquarie, Australia and have started working on a new community-based adventure project titled ‘Sea Stars of STEM’. The aim of the project is to encourage young people from around the world to undertake Science, Technology, Engineering and Mathematics (STEM) studies and careers.

The idea behind Sea Stars of STEM is to present school children with an exciting challenge (in this case to design and build an underwater habitat fit for a superhero) and guide them through it from concept to delivery with some industry support. I’ve found an amazing school here in Port Macquarie (Newman Senior Technical College) that has the facilities and capabilities to tackle the challenge with their students. They also happen to have a Marine Discovery Centre located onsite:

In order to help raise the funds I need to get things going, I have created a peerfunding campaign on StartSomeGood that I could really use your support on: So far I’ve raised $13, 642 of my $33,000 Tipping Point target. With just 21 days remaining, I urge you visit the link, watch the video and contribute toward my project in any of the following ways:

1. Pledge your support.

2. Share it with your network or with specific people that you believe would be interested in supporting this Community-based Science and Technology project.

3. Give me a shout out on your social media along with the link.

Thanks kindly for your help. If you would like any additional information please let me know and I would be happy to give you a call or answer any of your questions via email. Let the challenge begin!

Yours sincerely,

Lloyd Godson
