'We are talking about two different by-pass filters here...' *superb posting, david !! thanks for the effort, we all need to know as much about filtering as we possibly can. keep the hammer flying, the nail will be eventually be driven home...(:-D) cheers, dick. ------------ From: "F. Marc de Piolenc" <[EMAIL PROTECTED]> Subject: glycerine and absolute alcohol *i personally find marc's postings to be...well...epatant !!! what ? *except for a remark he makes offhand in the following one : 'The "energy balance" is not the whole story in any case. If the energy input is from a waste product and the energy out is in the form of high-grade liquid fuel, there is a net gain no matter how many BTUs are on which side of the ledger. A low pressure steam plant burning ag waste can furnish...' *there really is no such thing as 'ag waste'. if left to naturally transform, it will become organic matter, and help sequester carbon dioxide. if burnt it will produce carbondioxide, and then the carbon equation goes belly up. and when the carbon equation finally unbalances for good, we won't have any need for fuels or energy or whatever. 'cause we won't be around to make use of them. *also, ag waste soon becomes something else, as demand increases, and ag waste supplies dwindle. and before long we're providing the necessary energy by....you guessed right, chopping 'ag waste' trees down. *those selfsame trees we're losing at the rate of 3.5 % of remaining cover every ten years because nobody's planting trees for firewood (or clear lumber for that matter). *so it would make me infinitely happier if 'ag waste' is not taken lightly, but rather given a place in the energy equation. if we're going to use biomass for anything, we're going to have to replace biomass as part of the overall strategy. *maybe putting trees down so that down the road we have the required firewood. maybe going the hemp way. maybe mowing grass. or cropping sugar cane. but we will have to provide ex-ante the inputs necessary for the ex-post expected results. *and when we do that, we'll suddenly realize that what used to be 'ag waste' is now a precious commodity. *aside : marc, polytechnicien ? ----------- From: "Appal Energy" <[EMAIL PROTECTED]> Subject: Chip off the Old Block - or - Like Father, Like Son "That's a big no. The president believes that it's an American way of life, and that it should be the goal of policymakers to protect the American way of life. The American way of life is a blessed one." - White House press secretary Ari Fleischer on whether President Bush would call on drivers to sharply reduce their fuel consumption. Or "It's about preserving the American lifestyle." - President George Bush Sr., regarding the "UN" action dubbed "Desert Storm," January, 1991. *i have never understood why a country of such indubitable greatness as the us at times chooses to elect such shoddy, egotistical, narrow-minded, and short-sighted 'leaders'. *(not to speak of regan, who really took the price, and was elected twice) *you're not alone in this one todd, believe me...!!! ------------------------ vacuum pumps : i use pressure in my plants. very convenient. easy and cheap to produce. standard fittings, accessories, etc, available all over. pump meth and oil to the reactor by pressuring holding containers. pump glycerol and biodiesel out of the reactor by pressuring reactor. pressure vent all meth fumes to a manifold. i find vacuum to be a very elegant solution, but somewhat expensive and complex. compressed air is perhaps worth considering... ??? ------------------------ cheers, dick.
