Potential Fuel Source That Many Of Us Probably Have Access To
There are lots of things you can burn for fuel but liquid fuels are particularly nice because it's comparatively easy to set up fuel tanks that allow a steady draw over a long period of time with relatively little input or operating on your part. I've been looking hard at straight vegetable oil(SVO) for a while now and I'm growing sunflower(Peredovik is a good oil sunflower) and peanuts as my main oil crop. Just today I realized I had another massive potential source of oil, in fact a great many of us who own some land likely do... acorns.
I've been planning on using this year's acorn harvest as bird feed and I'll probably eat a little myself. Just out of curiosity I did some searching and apparently oil content in acorns ranges from 5% to as much as 30% by weight. Unfortunately I haven't been able to track down species-specific info yet but based on the huge load of acorns a big old white oak may produce in a year you're still talking about a lot of potential fuel for your diesel if you have the means to pressed it or crush, boil and skim off the oil. I've still got several months till I can expect my acorns but I have a large number of big live oaks on my property. Based on the information I've seen I expect them to produce about as well per acre as sunflower, around 100 gallons. I can raise some crops and livestock under the trees so it's a bit like finding a gold nugget in my back yard. When the acorns come I'll have some experimenting to do. Anyway, just thought I'd pass this on as a valuable natural resource to anybody with some oaks and a diesel or external combustion engine. From what I've read some oaks will bear a crop of acorns every year, for others it can take two years, depending on species. |
Re: Potential Fuel Source That Many Of Us Probably Have Access To
I thought most oaks threw bitter acorns?
In fact, I recall reading somewhere that people have tried to domesticate oaks to give sweet acorns, but have never been able to do so. |

http://209.85.165.104/search?q=cache...lnk&cd=1&gl=us That's old news, though. It's the potential of acorn oil as an abundant source of found oil for fuel that has caught my attention. I haven't been able to turn up too much info on the subject of yields so I'm going to run a few experiments this year. I'm going to try both the crush and boil and press methods, with green and ripe acorns. I might also try pressing for primary extraction then boiling the cake to see if I can get a worthwhile secondary extraction. |

If a person geared these correctly, would they be able to compress air efficiently? I can imagine powering one of these with a donkey or a U.S. Senator.

Here's an idea that practically anyone can utilize with a little out of the box thinking. Methane from compost stored in inner tubes. Check it out. Quote:

Re: Potential Fuel Source That Many Of Us Probably Have Access To
Rev, I'm not knocking the acorn idea, but it seems like you'd have to pick bushels and bushels of them. Are there really that many around you?

The link says oaks can produce 6000 pounds per acre. How are you going to harvest all of those? Do they have some kind of sweeper optimized for acorns? |
Re: Potential Fuel Source That Many Of Us Probably Have Access To
Well, let's see:
There are 43560 sqare feet per acre, divide by 6000 lbs equals .137 lbs/sq. ft. Looks like acorns are the fuel source that warms you twice! |

As far as harvesting goes, I wouldn't spend much effort on picking them out of the tree or off the ground. What you need is a sheet, tarp or something similar. Two basic concepts. 1, the simplest. Lay the sheet/tarp on the ground, let the acorns fall, gather the corners together and either carry it to your storage and processing site if you can move it or scoop it into a cart/wheelbarrow/similar if you can't. 2, a refinement of the first. Stretch your sheet out between poles, the outer poles taller than the inner poles so the sheet slants toward the trunk. This will catch the acorns as they fall and make them roll toward the trunk and off the end of the sheet, into a waiting bin. You can use a weight, bungie or other means to to create a funnel effect on the low side of the tarp, similar to how you set up a tarp to gather dew for emergency drinking water. A possibility for a mechanical harvester would be something like a shop vac, scaleable to whatever size, with two screens. The first screen would not allow anything much larger than an acorn to enter. The second screen would allow anything much smaller than an acorn to be carried out with the exhaust. The existing nut industry likely has other means of harvest that are worth looking into. If you assume that acorn oil weighs aprox. 7lbs/gallon which seems to be fairly standard for vegetable oils and pick a median figure of 17.5% oil content from a range of 5%-30%, 6,000lbs is 150 gallons of oil per acre of oaks. Below is a chart of oil yields of various other common crops, notice that acorn compares very favorably to such old standard commercial oil crops as corn, soybean, linseed, sesame, sunflower, peanut, olive, rapeseed and castor beans. <TABLE cellSpacing=2 cellPadding=0 width=362 bgColor=#ffffcc border=1><TBODY><TR><TH width=99>Crop</TH><TH align=middle width=59>kg oil/ha</TH><TH align=middle>litres

Re: Potential Fuel Source That Many Of Us Probably Have Access To
Domesticate squirrels to pick the acorns and stash them in containers set up under the trees. :D
From the information I've looked at so far, methane production is very easy on a small scale. Just using one truck innertube and some pvc tubing and you can build a little system that can produce enough methane to cook one meal a day, that from 3 coffee cans full of chicken shit or some other equivalent. It's really got me thinking, I may already be halfway there. Since I live in a bus, my toilet configuration is quite a bit different than normal. I know this may sound funny, but I'm thinking I may be able to grow methane and cook my food from my own shit. Wouldn't that be a hoot? :bear_w00t: My waste drops into a 100 gallon box. I have been pumping it out, into a humanure composting setup using a 12 volt macerator pump. That would remain the same, but if I cook it or ferment it first, then a large portion of the pathogens in the shit will be destroyed even before I transfer it to the compost heap. The box is vented through the roof, allowing oxygen into the box, which ruins the chance for methane to build up inside the box. However, if I can stop oxygen from entering I will have a good chance of capturing methane and piping it to a gas bladder like a big inner tube or even a series of inner tubes. I guess the question is, do I alone have enough gas to support my cooking and heating needs. :D |
Re: Potential Fuel Source That Many Of Us Probably Have Access To
I don't know much about the practical applications of methane at present but just giving it a quick look over with what you've posted here it would appear that a septic system could be converted or created to double as a methane generator. When I had mine pumped out I was told that you have to be very careful working around them because you can pass out from the methane fumes before you know what's happening.
Not sure I'd cook my food directly with that methane, though it may be fine. Either way you could definately use it to heat something that you then cook your food on in turn. I'm hoping to build a new house in a few years and that will encompass replacing my current septic system. If I can come up with a good septic powered methane generator between now and then there is no reason I see to not go that route. One more aditional found energy resource. |
Re: Potential Fuel Source That Many Of Us Probably Have Access To
One thing I find ironic, is how we in the first world are apparently way behind the ball where it comes to self sufficiency.
India and China have been spending vast sums of creative energy with small scale methane production where even now millions of rural people are reaping the benefits of cheap simple home grown methane. I'm not saying first worlders are stupid, it's just that we've been hoodwinked by sugar daddy into believing he will take care of all our needs. Ok, maybe most of us are stupid, sitting on daddy's knee, completely unaware that daddy is slipping our little knickers down. :shocked_ma: We seem to have forgotten how to take care of ourselves. How to grow our own food. Our own energy needs. Our own spiritual connection to the world. Those three things go hand in hand, imo. I believe there's enough energy just laying around going to waste in our own yards to supply us with our needs indefinitely. I also believe that "necessity really is the mother of invention." Unfortunately, I don't have access to good sweet acorns on this six acres. What I do have in abundance though, is bahia grass, and after reading up on various permaculture ideas, I recently realized grass' potential as compost. So, for the past month I've been a mowing and bagging fool. I've been mulching the garden like crazy. I've been mulching and composting every tree. Dozens of young Sycamores and citrus trees, and let me tell you, it's already making a huge difference in their health and sturdiness. By the way, I live in horse and cattle country. Factoring conservatively, going by what I've harvested so far this summer, I'm figuring a minimum of 200 square bails worth of grass this wet season. Buying a square bail of bahia around here runs about $5 or $6 a bail. Since I pretty much have to mow anyway, I'm saving plenty of FRN's for better use. Silver... That's not mowing the whole six acres. Just the lawn area, about 1 and a half acres. Still, it's keeping me busy between the rain storms. I know it sounds stupid simple, but for me simple is usually the first thing I tend to overlook. This grass wouldn't be much good for livestock though, due to the method of harvest, a Snapper riding mower. Too dirty. I also have a 25 hp diesel tractor and a bush hog, but as of yet, no way to gather the grass growing out in the field. Grass also produces methane when it's composted hot. I want to thank you, Rev, for sort of helping me think about chickens. My next little project is going to be a chicken hutch with a door right out into the fenced in garden, where they can help me manage the bugs and nuisance weeds and last but not least, feed the garden. I've got rabbits already. I've been putting it off out of concern over what to do about five knuckleheaded dogs and two cats who think they own the place. All this symbiotic inter-dependency stuff has my head swirling with an unusual optimism for the future. I'm growing a bit fatigued by all the "WTSHTF" scenarios, Now I'm starting to realize (remember) the end is just a new beginning. I've spent time in Mexico, Central and S. America, and aside from some inconveniences, what is known as the third world really isn't so bad. It seemed to me that average people down there knew something we somehow forgot in our lust for linoleum and mega-malls. How to smile and cry unselfconsciously, in the face of our own beautiful nature. |
Re: Potential Fuel Source That Many Of Us Probably Have Access To
I've been keeping my 3.5 acres in check with a push mower while I await large herbivores. There is quite a lot of useful compost to be harvested that way but my pond is my main source of composting material. Duckweed and spatterdock. You can't hardly erradicate that stuff if you try, it's self-composting and grows back very, very quickly. It will be key in my high intensity market gardening operation. And it's producing fish and storing water for me while still yielding compost. Beautiful!
Yup. You can accept the realities of the world for what they are, but instead of focusing as much energy into worrying about SHTF you can put that energy into creating systems that will minimalize its potential impact on you. In fact you can create systems that will make you wealthier and help out your fellow man in such conditions. I've noticed the same effect about the third world, they're the ones getting outfitted with all the sustainable technologies while we're circling the drain. You don't have to be primitive to be renewable and sustainable, just thoughtful. I made a new discovery. Okra seeds have 40% oil content. The total yield per acre was said to be about the same as sunflower, so around 100 gallons. This is very interesting to me as I'm growing cow horn okra, a particularly large cultivar. |

So, if you run the gas through iron filings and then bubble it through water, the remaining gas is perfectly clean.

Re: Potential Fuel Source That Many Of Us Probably Have Access To
Here's a modern small scale methane producing biodigester design built with HDPE.
http://biorealis.com/digester/construction.html Check it out. It looks pretty simple to me. Something easily and inexpensively built. I'm not sure I understand the function of the bulkhead fittings, though. This little unit might be nearly perfect for the septic setup in the basement of my bus, replacing my existing 100 gal. black water box. The effluent could be pumped out via a 12 volt macerator, the same way I'm doing it now. Pumped out 99% detoxified, into the humanure compost to further break down into super rich organic fertilizer. The gas could be scrubbed through 2 paint buckets. One filled with iron filings and the last one with water. It may also need to pass through some sort of drying agent. Not sure about that. I think methane is inherently a dry gas. Finally, it could be compressed into standard propane bottles. That way I wouldn't have to alter the stove/oven, water heater or my platinum cat catalytic vented heater. Not only that, I could run the fridge off this stuff. Not only that, I could run my 8 kw diesel generator off this stuff.:bull-buddy-icon: I wonder how expensive a scuba tank compressor is? |
Acorns are eaten by Koreans who make
a jello out of the power of the acorns, they soak in water many times then ground into a power after sun drying. A shoe box sized jello square can be sold for about 10.00$ , it is considered a healthy food and used as a side dish not much taste so soybean oil is added .

Re: Potential Fuel Source That Many Of Us Probably Have Access To
Not up to date on the science of acorn to fuel, but here is my two cents. Acorn mast production in central Indiana has been poor at best much of the last decade. I am not sure what your figures are based upon, but I figure it's from a good mast. We have plenty of oaks but few acorns. Not sure the effort would be beneficial in my neck of the woods.
