Thanks for your pleasant response.  I am learning so much from your book, I can not thank you enough for the personal, direct help that you have been providing.  I am looking forward to heating my home this winter with biodiesel made in your reactor!

You say I was patient, but the fact remains is that what pulled my legs into all this, was the respect and attention you first gave my query and later on
the problem we went into. I really admired this, and I thank you for all the patience and time you put into this as well.

I am absolutely delighted with the book, It is an easy to understand fully comprehensive guide for everything that I need to know about constructing a processor, and producing bio diesel.

Many thanks.  I was thinking more in terms of ion exchange resins for removal of glycerin and KOH rather than the reaction itself.  Still best book I've seen and believe me I've read a few.

July 1

Very nice book layout at a glance it already cleared up a couple of things, photos will follow when my system is complete.

Can't get past the index at the moment.  As I scroll down the page I find something else I want to look at and forget to start at the beginning.  Improved my technique enormously so thank you very much. Found your book on a Google search and you were the only ones that have chapter and verse on pretty much everything I wanted to know.  Thanks for the passwords for the books which worked faultlessly and for the members area.

While talking to Don on the telephone the subject of Biodiesel came up. I mentioned seeing some info. on the internet. What they had to offer sounded like the pie in the sky and I don't put much faith in that kind of stuff. Don said if I'm really interested check out your site because he feels your honest and a very knowledgeable on the subject. After a couple of nights on your site I want to take the next step and read "Pretty Good Biodiesel Book" and "Advanced Biodiesel Projects".  I will send money tomorrow. Thanks for your help,

I've been wanting to get us converted to biodiesel for some time even though currently the only vehicle we can run it in is the tractor. I was plugging around on the internet and found your website-- which was exactly the informative, and comprehensive style I was looking for-- Thank You! and thank you again for such a quick response about the pass codes—the books are now downloaded no problem.

I must compliment you on the research that you have done in putting your book together…

I have been doing research for over a year trying to find the no nonsense information that you

have gathered in one place.
