Making Algae Biofuels at Home

Dear sir:

Great news! You are finishing to write one book expected for many years. During several months, I have been an constant follower of your ideas, papers and designs and there is no doubt of your worldwide mastery about biofuels. I am a Colombian researcher dedicated to participate in the Colombian project for production of biodiesel from native microalgae…. It will be as our Bible on those topics really urgent and necessary for the future wellfare of the humanity.

Thanks in advance


David, just read through your book on algal biodiesel. Nice layout, easy to read with emphasis on building from local materials and good optimism. We may use some of these ideas for our engineering senior design course this year on biofuels production. Thanks..

Making Algae Biodiesel At Home

I’m not a biodiesel expert, but I would say that in his book, Making Algae Biodiesel at Home, David Sieg provides more than enough information to tackle this process with confidence if you have the inclination to tackle a do-it-yourself project of this magnitude, which will require dedication, patience, and natural skill. He provides concise overviews as well as in-depth resources for understanding the process and its variables, including tips from commercial versions and national labs. The guide covers all aspects required, including selecting, growing, harvesting the algae; and making the biodiesel. Though the process is certainly not easy, David skillfully makes it easy enough that it is within the grasp of doing this at home. His guide is well-organized and well-written, accompanied by abundant illustrations, photos, and diagrams. Best wishes.

Hi David

Hi David,

Your Making Algae Biodiesel at Home is a terrific document. Congratulations on probably the best collection of information anywhere on the topic. I’m going to be completely honest. I’m a guy who is looking to develop algae commercially, partly because this is so complicated and partly because we need to get off petroleum no matter how we do it. Moreover, if we can integrate this with waste water treatment and powerplants we can make a big dent in cleaning up those guys. I am partnered with some excellent scientific resources in the Woods Hole Oceanographic Institute and the Marine Biological Laboratory.

Dear David,

I am a small farmer that is suffering from the Economic downturn and would not have had the finances to afford it at this time. I believe your work in research on algae and your willingness to share with us maybe at the center of new world wide wealth for the under privileged. The greatest aspect of your work is the empowering of the little people. You’re making us aware we have other choices, we will no longer in bondage the big energy companies. You have demonstrated this is not complex. We can do this.

Hello David & Tram ~

* VERY * Impressed Customer. WOW ~ I just purchased your Algae Biofuel package and I can’t wait to dig through it!…As the inevitable peak oil effect manifests as tightening heating oil supply, I’m concerned for family & loved ones across the Northern regions. I consider shortages of heating oil to be far more critical than shortages of gasoline ~ in terms of real human impact. Freezing to death trumps riding a bike any day.Thanks for publishing this important book.

Hi David-

So I just purchased your ebook Making Algae Biodiesel from Home, and I have been reading through it without performing any of the steps, as you requested we do in the book. As I have been walking around the military base I am on in Iraq, I have been keeping an eye out for algae growth, but there is just a lack of natural bodies of water here.

I will keep reading the book and doing my best to find a local sample. Even if it doesn’t yield much oil I would at least like to become proficient at growing algae and gain an understanding of all the variables influencing its growth. I have a year or more to work on it so I know I can get something to happen! I am enjoying the reading so far and I plan on buying more of your books when I feel like I am a little more advanced. Thank you for sharing your knowledge!

Kevin Bunday

Thanks again, from what i’ve read so far it looks like a great book!

Casey Lisle

This is a wonderful book. see if you can organize a workshop.


Hi David,

Yet another excellent book, this will help me immensely in my project here in the
UK-Thank You David for all your effort in producing this masterpiece.

Rod Padwick

Hi David,

I’ll end with that question, but I’ll say up front that I feel SO blessed to have found your site
and all the books that you’ve already produced.  I’m a neophyte to Algae but I’ve ‘kinda been
beating the drum about its benefits for about a year.  To have found your site, to find that
it so clearly lay out so many of algae’s benefits, and to have such a ridiculously low price for
the information – it’s truly a Godsend.

Dave Blankenship

I love all of it. I dream of making biodiesel and constructing sustainable housing. I need to stop
dreaming and start doing! thanks for your inspiration,

Unsolicited Testimonials for “Building Open

Once again, David Sieg has composed and excellent guide, this time focusing on open
ponds for growing algae, whether for fuel, food, animal feed, fertilizer, or even cosmetics. He covers the range from home use to large-scale commercial systems, from a distributed and survival perspective; yet practical enough for modern implementation — a hallmark of true sustainable principles. We’ll be consulting this guide in the Safe Haven Villages (.org) intention community I’m involved with. In a day when central authority is growing more tenuous, the ability to do things in a distributed model is growing increasingly vital; and it just makes more sense from a seventh-generation sustainability point of view, while still being profitable in today’s economy. In fact you might consider this as a career that will not only survive the downturn, but help you and many others make it through the worst of times to come; all while pioneering a future industry.

Hi David,

Yes it does make sense and is very clear. I am a Professor of Chemical and Biological Engineering
specialized in chemical and biochemical reactors, I have over 400 papers, 4 patents and 4 books…I like your simple books to the ordinary person

David really knows what he’s talking about when it comes to biodiesel. And his new book
“Building Open Ponds” shows it… it’s 157 pages jam packed with tons of great information from growing algae in an old bathtub to large scale algae farms. Great details and pictures to make it as easy as pie even for the novice. David really goes the whole nine yards when he writes a book!

Bill Anderson, author http://www.electricitybook.com


This is a great book on how to make algae biodiesel using ponds. People around the world contact us all the time about creating renewable energy using algae. This book makes it possible for them to do so in their own back yard. Great job!

Vic. Garlington


I can’t say enough about the quality information you have presented here and the fact
that I can visualize making any one of the systems from the information you have given me in the book is a powerful motivator.

Howard Bankston


Hi David,


Thanks for letting me know about your amazing new release, “Building Open Ponds” with me. I just finished reading thru it & thought it was fantastic! Your presentation of the great variety of uses for the algae that anyone can grow themselves was excellent. In additional to detailing all the factors to consider & how to set up different sized open pond systems, you provide some great info on many other important aspects, including harvesting & de-watering steps.


Thanks also for including Ron Putt’s feasibility study in your Bonus Materials — it’s another great source of valuable information. As you know, my organization, Terra Endeavors, is in the process of setting up small-to-moderate sized, commercial scale open-pond systems to provide rural communities in developing countries many of the algae-derived benefits you detail — nutritional supplements to fight malnutrition & for export revenue, bio ethanol, high-protein animal feed & organic fertilizer. This book will be instrumental in helping us design & operate the best system possible!


I highly recommend Building Open Ponds to everyone with an interest in anything algae related!


Best regards,

Charles Abramson

The book details facts about the forgotten fields of organic fertilizer, healthy natural foods, and above all an insight on how to become an entrepreneur. Am a graduate of Biochemistry in Kenya and i find your books so resourceful as i am also working on a project of starting a nutritional magazine as there is none in the Kenyan market.


Keep up the good work ,you should send one copy to Mr.Obama…

Harry Leon

It will be great laying hands on this book. I know you can do it. Regards.

I try to start research about domestic algae utilisation for biodiesel production in Bosnia. I need any useful information and I think that I’ll find a lot of them in this book.


Thank you in advance.


Thank you for letting me be on your site. I’m just now getting into making biodiesel from
WVO and know I will soon need to expand into something better. I think you have the answer.
you for letting be soon be a part of the solution for self reliance. I will purchase your
information just as soon as possible to raise the funds.
I am totally disabled with limited resources and must be careful with every purchase I make in these trying times.
God Bless you and your family for making this available, your information just might save many people’s lives.

Thank you again, I will contact you as soon as I possibly can.

As with all private innovation today, this technology will probably be suppressed and,
or, made illegal by the power elite. Getting started now will give the head start that will surely be necessary for any type of success. God Bless the “garage” engineers!

Ghana is the star of all African Countries and in fact the first to be visited by President Obama during his first historic visit to Africa. We have struck oil but I know that our future lies in the cheapest environmentally sustainable source of biodiesel and algae stands out as the best. The bioreactor will be the pilot project as a sequel to a commercial production source, the first
of its kind in Africa. I am now 61 yrs old and an environmental economist with over 36 years experience since graduating in 1974 as an agricultural economist. My desire is to promote environmentally soundand sustainable technologies for the production of clean energy. To my utmost conviction, algae is themost environmentally appropriate and most economic source for the production of biodiesel and oilscompared to all other sources be it fossil, agricultural or other environmental endowments – a solutionto the world’s quest for sustainable and clean energy production.
