this is my kind of thread....
wayne, i agree with your points and I also agree with sandcruiser and jim's comments.
i run svo and make bd and have seen this issue of folks trying to downplay the time/effort involved in doing it. people always ask me how much it costs to make bd and truthfully about .50-.75/us gal. for me. But would i sell it for that, no way. time and effort to setup my system was extreme and putting a value to the knowledge i've gained over the years of researching and trial/error is very difficult. I'm torn on this whole issue because I do really enjoy it, just like other folks enjoy riding snowmachines or doing other recreational activities. it seems that if something can be construed as a business (ie making BD, wind/solar installs) then it leaves the realm of enjoyment and gets evaluated as a business where folks who do recreational activities (ski, motorbike, etc...) never get evaluated as a business and aren't viewed under a microscope and expenses/time put into it are not really taken into account. this is a dilemna for me because the bd/svo thing is my recreation but might turn into a business venture.
i think that sandcruiser makes some good points regarding the costs of spills/cancer/wars/etc... this is one of the biggest reasons i make bd (local economic support, domestic, more environmentally sound fuel source).
i do think it is important as wayne says that we disclose all the issues regarding making this stuff. if anything is hidden or glossed over than it gives the perception of being deceptive and you lose credibility. Frankly here are some of the crappy parts of making the stuff that I've discovered:
getting grease in the winter is a PITA. i am fortunate enough now to have a crane on my truck so i can pick barrels up but before that i scooped the solid crap out of the barrels every month and stored it until spring. fun fun.
dealing with the catalyst (koh/naoh) IS NOT healthy. very caustic and i use every precaution possible (SCBA, respirators, no open tanks etc... and you WILL breathe some of the stuff.
methanol is nasty, no way around it, i've limited my exposure through a closed system but honestly hooking up the system you do get methanol around you.
dealing with the sludge left over from the grease is unpleasant. i compost it but getting it out of the barrels isn't all that fun.
BUT, all those above things are worth it to me for the reasons I stated above. I'm willing to endure those issues for the larger ones. No different than cleaning my kids dirty diapers....don't really enjoy it but something that has to be done.
