I wonder why you're being so defensive? "Insulting"? Well, if you insist on being insulted I guess there's no help for it. But believe me, Noam, if I'd set out to insult you I wouldn't have left it in any doubt whatsoever. As it is, I doubt anyone can see any insults other than you.
>This was certainly not my first attempt. I have made many test >batches, and we made test batches in my class the previous week. And >yes this was our first attempt making a 5 gallon batch.

There are people here from more than a hundred countries, and I believe your country is the only one, or at least one of the very few, where they refer to oil as "grease". If you're going to take offence if someone asks for clarity to help answer your questions then you mustn't expect much further patience from them, or from anybody. Your first message did not specify what oil you used. It didn't specify much at all. >The problem I was having was how to mix larger quantities of >methoxide. Not all of us can have a completely closed system >immediately. Any of us can very easily acquire an HDPE carboy. >We can do our best with what we have and what we can afford. That >doesn't make us any less important. If me and the other list member who responded to you considered it unimportant we probably wouldn't have bothered, no? >It seems to me that this community could use a bit more respect of >those that have less experience. I'll tell you something. With our VERY demanding project, Journey to Forever, we have only a marginal interest in whether one more or less American or citizen of any other industrialised country makes biodiesel or not. We also have little interest in whether or not such folks join the Biofuel list, stay and prosper, or leave in high dudgeon, or whether they visit our website or not, we already get far more visits than we can easily handle. Our focus is on sustainable fuel and energy for 3rd World rural communities, and even then only as a part of an overall Appropriate Technology approach. What happens in the industrialised countries is of little interest to us. Yet I spend an inordinate amount of time that I DON'T have to spare helping industrial-nation newbies learn how to make high-quality fuel reliably. Including you. I don't need to be told to have more respect. Others here are in a similar situation. They spend a lot of time that they also don't have to spare helping newcomers to learn. They also don't need to be told to have more respect. You do though. >I have read Tickell and read much on Journey to forever. When >someone has a question it honestly doesn't help much to refer me to >websites- I have seen this already. If you'd already seen the links I referred you to you wouldn't have asked the questions you did and saying you'd used a plastic bucket and a paddle. It's obvious you didn't bother to refer to the links, and still haven't. That's not insulting? But I didn't get insulted, just referred you to them again. Why don't you climb down off your high horse and check them out? >I checked the very same sites before posting my question (i wouldn't >waste bandwidth). But to no avail it seems. It's right there in the index, how come you didn't see it? >It was something I hadn't seen before, either personally, on the >list, or on the web. I don't think responding with condescension to >those who are less experienced really helps any of us. What nonsense! >I was hoping that the list could be a source for those of us who >have only been doing this a few months to trouble shoot. What I got >was a bit insulting, with all due respect. i haven't really had any >of my questions answered. Yes you have, but... >How is that helpful? ... you can lead a horse to the water, and that's all you can do. Not too difficult to see what's going on here. I think you have to choose. I think you already have. Pity, that. Helping newbies? I don't need much encouragement to chuck it in and get on with too many other pressing things that are much more important to us. I think you may just have provided that encouragement. What the hell, we've been running this list for four years now, helped build up a huge treasure-house of an archives where people can find everything they need to know if they're but prepared to look, we've spent vast numbers of hours providing and maintaining the resources at our website (and doing the work itself!) which constant feedback tells us is more than enough to learn to make biodiesel... And we didn't have any of this, nor any help from anyone, all we had was 13 paragraphs we found on the Web. A lot of us here can say the same. Sod it, enough already. Do it yourself!
