One model heating unit already on the market makes enough power to run its own fan, recharge storage batteries, all the while supplying enough heat for the house. The next generation units are predicted to generate enough electricity while heating the home to power the rest of the house's needs and put juice back into the power grid during low energy need times.

Re: [biofuel] Re: Filters
Keith, How true. How very true. All the more reason to get some of these other technologies up and running as fast as we can. At a time when the american people and the world needed a progressive, far seeing individual, with a vision for mankind, they seem to have taken a retrograde step and elected a president who is a chip off the old block with the insular thinking of 50 years ago where the world was divided into power blocs and centres of interests rather than being a truly global economy with man helping man and all of us doing our best to help one another. Perhaps I am prejudging the man but I aint seen nothing yet to even start me thinking that perhaps I am wrong. Still it is early days but I hope we dont get 4 years down the track to find nothing changed. The time for change and the introduction of novel technologies is now. This new Energy Policy seems to have nothing new and with Acceptance of the Status Quo stamped all over it. Lets hope I am wrong. Like JFK or not there certainly was a dynamism about that era with the start of the space age that certainly seems to be lacking in the current crop of world leaders. I believe some of that came about as a result of right or wrong America under a young JFK made a decision and ran with it. It is this sort of impetus that is required today here and now in relation to energy. Otherwise hell who knows if we take all the oil out of the earth as quickly as we are doing at present the world may fall on its side and those now basking in the glow of modern technological advancement may be situated at the position of the North and South Poles. B.r., David We are told that there is enough oil to last 70 years if we keep finding oil at the current rate but with the increasing number of vehicles on the road and countries like China coming on line I seriously doubt if there is 35 years supply left. B.r., David I doubt we can take another 35 years of the side-effects.

Re: [biofuel] Re: Filters
Hi Barry, See I didnt answer this e-mail properly. The fuel filters are basically the same as the oil filters although slightly different. They differ in that while the oil filter has a 50 thou orifice in the inlet opening to drop the oil velocity and to prevent channeling the fuel filter entry is is the same or bigger than the fuel line size so there is no restriction and fuel can progress unrestricted. They also have a cock or tap on the bottom so you can drain them occasionally or every so often, to remove the water which tends to settle out, especially when idle or sitting for a while, and for taking fuel samples for visual examination and inspection. As such the filter element will not fit the canisters you mention. Nevertheless when fitted in conjunction with these as the final filter with a diesel they will give you superfine filtration removing the asphaltine particles and other fine contaminants present in all diesel fuel which are the biggest cause of soot (carbon) and exhaust emissions. When fitted together with a by-pass oil filter they help prevent carbon particles entering the crankcase oil to quite a large degree in the first place and thus help to achieve the cleanest system possible and extended oil and engine life. Both MIL-MAC oil and fuel filters will work exceedingly well on this type of vehicle. There is also generally plenty of room for fitting them and easy access. I can assure you that you will be very happy if you fit them.

I dive a toyota 4wd diesel with standard fuel filter element in the metal canaster used by toyota, mitsubishi and daihatsu diesels. Can I make a Mil-Mac filter element fit in one of those?

Re: [biofuel] GE oilseeds - was RE: Palm and coconut oil
If you look at the yields from oil bearing algae compared to soybean or rape, that is the best area to throw the technology at rather than improving current crop yields,and pushing bio-diesel further into the clutches of M--s--t- and Ca-g--l and the like Oil,grain,soybeans, it's all the same to them. The beauty of bio-diesel as I see it is that it doesn't need large corporations to make it work. It can be produced locally and sold locally. Economies of scale is usually a euphemism for larger profits for the few. It doesn't have to be that way with boid. With petro diesel you can't just go out and drill for it. You have to invest billions in exploration, so the oil companies keep telling us when asked to justify their 3 million pounds a hour or whatever. This may be true ,but their motivation is profit for their shareholders, not can I take less from the enviroment This does not strike me as a sustainable system.

[biofuel] Still Help
Keith, Can you tell me if it makes any difference what type of metal one uses to build a column for a still. Stainless steel is preferable but could one use auto or diesel exhaust tubing/pipe. I know that plain steel will rust after a period of time but if you clean the column with regularity would it make any difference. I'm not a drinker but I don't want my product contaminated. Also I have been reading some of the material you recomended on the net(great stuff)but am curious about my math. It seems that it will take about 25 pounds of wheat or corn in a mash to distill one gallon of product/ethanol. Is my math wrong? Your help and others who have replied have spurred me on to more reading and although I must say I am quite anxious to build my still I still do not know what size I need to build. I would like to produce say five to ten gallons a week if possible.

[biofuel] drying oil
hey, folks, this seems a little obviuos, but I have a batch of oil that is cloudy, I'm not sure why, but i have assumed that it has some water emulsified in it somehow. I have made two batches now, that have had varying amounts of a thin waxy film on top, and a milky appearance after washing, and the second batch has abunch of what i think is soap on the bottom. what i want to know, is how to be sure the oil is all the way dry before I make the batch, if my assumptions are correct, or if anyone has some ideas as to what is making the oil cloudy in the first place. I have heated the oil, in a 50 gallon batch , to 225 degrees, at which point i assumed the water had all been boiled out of it. is it possible to attain 225 degrees without the water being boiled off? how long should I have to keeep it at that temp to boil off the water? why is my stored (before the heating) oil staying milky, and not settling out clear? will boiling the water out of it make more free fatty acids? my oil comes from a place that fries corn chips, and most of it has been fairly clear, and these are the first batches I have had any trouble with. thanks all, anton Burn vegetables, not dinosaurs!

[biofuel] My first 80 litre batch
Hi all. Well, I finally did the first large batch yesterday. Using alecs' 'foolproof' method. I think i messed up big time. My system worked perfectly although it took nearly 2 hrs to filter the oil. My mix was 80% liquid veggie and 20% solid veggie. 80 litres in total. I heated it all up to 100oC until i could get no more water from it, (there wasnt much). I sucked it thru the filter (). got the temp to 55oC then added 8 litres of methanol. 5 mins later added 80ml 98 proof sulphuric. I then mixed for 55 mins then stopped heating. This is where i messed up. Going by Alecs, I gave the mixture 1hr 40 mins before adding the first half of methoxide (4 litres). But, wait for it, that was after the initial 55 mins :( . So, the base cat was working for 2hrs 35 mins. This morning, expecting the worst I opened the drain expecting thick dark gunge, it didnt happen, I got really murky mid brown oil, there was no seperation. So, i thought what the hell, heated up the whole mix to 55oC and added the final 4 litres of methoxide. Mixed for 10 mins stopped heating and stirring. Now all i can do is wait till 9 this evening to see what ive got. My caustic seemed rather white, so i mixed the methoxide using 280gms to 8 litres meth. Apart from my stupidity, the whole system was flawless, except i drew water in from back siphoning from the bubbler to the vacuum unit. Ive since put a one way valve in the system. The water didnt reach the mix it just filled up the liquid trap some. Any suggestions?

Re: [biofuel] Gathering Materials
I want to make ethanol from newspaper, something I have in rather abundant supply, I was wondering if anyone knowes where I can get the enzymes to change the cellulose to glucose. Thanx, Buddy Hi Buddy I wasn't too surprised that you didn't get any responses, at least not on-list. If you find out, please let us know. This might help: Ethanol resources on the Web - See Ethanol from cellulose: http://journeytoforever.org/ethanol_link.html Good luck!

Re: [biofuel] Why you should fit a MIL
Barryt,I have used a Mil-Mac filter on my Landcruiser 2H diesel for about 10 years,not for oil,but fuel filtration.Replacement toilet rolls have been Bunzil 2 ply,though a friend has successfully used Lady Scott toilet rolls after peeling off a few layers to achieve a tight fit in the container.The idea was to clean up the cheap diesel BP were importing from Singapore,after a couple of weeks the toilet rolls were black indicating their effectiveness. You can contact the manufacturers at Mil-Mac[WA]PtyLtd,47 Cohn St,Carlisle,Western Australia. 6101.Phone0894721888 Fax94703207.I am sure they will be glad to supply you with further information David, I loved your information about the Mil-Mac bypass filter. What you say about engine wear really makes sense. You said in a previous email that it was an Australian product. I'm Australian and I can't locate it. None of the people that I have spoken to are aware of the Mil-Mac brand. I have looked on the web and couldn't find a Mil-Mac site. Not in the phone book. Perhaps they are known here by another name. Can you please give me more information.

Stills - was Re: [biofuel] Using the archives
Keith, I went to the archives and found Robert Warrens paper on stills he had designed but I can't get his e-mail address. I would like to purchase the plans he spoke about. Could you help me? I really need to get this going soon. Thanks, Ron [EMAIL PROTECTED] Hello Ron Oh dear. If you'd searched a bit further you'd've found out why we dropped both that still and its promoter from our website. To be brief, it's a no-no. It won't live up to his claims for it, it doesn't do the job, and independent experts have warned that it's dangerous. The plans are unclear, the directions for building it are most confused and contradictory, the parts list is wrong, and impossible to fit to the directions and the plans, and the instructions for use are, well, benighted. Like the rest of it. I think the paper you found may have been my rework of Warren's confused material, which I did to try to help people who'd already bought the plans (but I couldn't guarantee the results of my work on it). Forget it. Really, that's the best advice. I know it looks tempting, but you'll just waste your money and your time. We managed to find only ONE person, out of more than 60 who'd bought Warren's plans, who actually got the thing working, but the performance was poor. He got much better results out of a StillMaker. You'd be better off scaling up a StillMaker. Bob Lennon, the designer, told me there's no problem in scaling it up. Meanwhile other designs are in the pipeline, very promising, but not ready yet. Sorry, Ron.
