The first two methods sound easiest, but, as so often in life, it's not quite that simple. Vegetable oil is much more viscous (thicker) than either petro-diesel or biodiesel. The purpose of mixing or blending straight vegetable oil (SVO) with other fuels and solvents is to lower the viscosity to make it thinner, so that it flows more freely through the fuel system into the combustion chamber. If you're mixing SVO with petro-diesel you're still using fossil-fuel -- cleaner than most, but still not clean enough, many would say. People use various mixes, ranging from 10% SVO and 90% petro-diesel to 90% SVO and 10% petro-diesel. You might get away with it in summer time with something like an older '80s Mercedes 5-cylinder IDI diesel, which is a very tough and tolerant motor -- it won't like it but you probably won't wreck it. To do it properly and safely you'll need what amounts to a proper SVO system with at least fuel pre-heating. Mixes and blends are generally a poor compromise. 1. 2.

Genneo - Power Through Motion by Blake L Isaacs & Daniel Mota VeigaTHANK YOU to everybody who has backed us so far! If you like this project but can't back it, you can still help us out tremendously by sharing this page with your friends on Facebook and Twitter. Or by talking about it. Genneo has created a revolutionary line of products that capture energy from walking, shaking or moving in other ways and turn it into charge for your phone and other portable electronics. These products are easy to carry and they capture energy as you move normally, storing that energy in their on-board battery. If you’re in a hurry, they are also optimized for fast charging when shaken, multiplying the charging rate by 20 or more. Different from spinning generators or solar generators, the Genneo charges from natural human movement, so it quietly charges up as you walk or run. Just have it with you and you’ll always have power! With your help, Genneo will soon launch the G4000 and G3000 Mobile Generators. Shaking the Genneo accelerates charging. Genneo GO T-shirt.
BiodieselBus run by biodiesel Space-filling model of methyl linoleate, or linoleic acid methyl ester, a common methyl ester produced from soybean or canola oil and methanol Space-filling model of ethyl stearate, or stearic acid ethyl ester, an ethyl ester produced from soybean or canola oil and ethanol Biodiesel refers to a vegetable oil- or animal fat-based diesel fuel consisting of long-chain alkyl (methyl, ethyl, or propyl) esters. Biodiesel is meant to be used in standard diesel engines and is thus distinct from the vegetable and waste oils used to fuel converted diesel engines. The National Biodiesel Board (USA) also has a technical definition of "biodiesel" as a mono-alkyl ester. Blends Biodiesel sample Blends of biodiesel and conventional hydrocarbon-based diesel are products most commonly distributed for use in the retail diesel fuel marketplace.

Test-batch mini-processorSpanish version -- Versión en español This mini-processor is easy to make from not very much, mostly kitchenware, along with an electric drill, some scrap iron and a few bits and pieces.It's effective and safe, closed and virtually air-tight, with no splashing or leaking of hot fumes, and it has full temperature control.It makes one- or two-litre batches, for tests or for demonstrations. It's suitable for the single-stage and two-stage processes. And you can take it anywhere.It's the ideal processor for beginners. Unlike kitchen blenders, it closely mimics the processing action of full-scale reactors in miniature -- it's much easier to scale up when you're ready for full-sized batches. Cut a square hole in the lid the exact size and shape of the bush; cut another hole in the lid insert.
CoeLuxTerrific new beehive design doesn't disturb bees when you harvest honeyThe worst part of being a beekeeper us pulling out the honey-laden frames from the box and tearing them up to get the honey. The bees hate it and so do I. That's why this new hive design, called Flow, is so cool. Cedar Anderson and Stuart Anderson have spent over ten years developing the Flow hive. It uses special frames with open cells that allow honey to flow through a pipe when you want to harvest. I've never seen anything like it, and if it works as advertised this will revolutionize amateur beekeeping. RELATED: Read about my beekeeping experience in my book, Made by Hand: My Adventures in the World of Do-It-Yourself.
Washing Machine Drum as a FirepitWith festival season in full swing, we've been spoting lots of inspiring and easy solutions for reusing items. John was recently at Croissant Neuf Summer Party and found this safe and easy way to have a fire. It is especially useful when campfires are not permitted because the ground remains unburnt. A simple solution for camping, festivals or garden parties.

Algae Cultivation - Tubular Photobioreactor - Oilgae - Oil from AlgaeAmong the proposed photobioreactors, tubular photobioreactor is one of the most suitable types for outdoor mass cultures. Most outdoor tubular photobioreactors are usually constructed with either glass or plastic tube and their cultures are re-circulated either with pump or preferably with airlift system. They can be in form of horizontal / serpentine, vertical near horizontal, conical, inclined photobioreactor. Aeration and mixing of the cultures in tubular photobioreactors are usually done by air-pump or airlift systems. Tubular photobioreactor Tubular photobioreactor are very suitable for outdoor mass cultures of algae since they have large illumination surface area. Tubular photobioreactors consist of straight, coiled or looped transparent tubing arranged in various ways for maximizing sunlight capture. Also, it is difficult to control culture temperatures in most tubular photobioreactors. See the following sections in photobioreactor:
How To Build a Gravity-Based PVC Aquaponic Garden Very Easilyposted Categories: Green If you haven't been introduced to Aquaponics, the idea is simple. You want to create a sembiotic relationship between fish (namely talapia are used) and plants. The fish poop, creating fertilizer for the plants. The plants act as a filtration system, cleaing the poop out of the water. In this version, it's soooo cheap to do. Buy a hole saw and drill them out in succession. Connect the pvc with elbows. Cups make great planters, because they will sit right down in the hole snugly. Plant to your hearts content! Now watch this: Related articles in Green
Tree Speakers - Viewing Comments 1-40These tree speakers were handmade from +14" thick sections of what was once a towering elm tree, that have now been transformed into a completely unique piece of hi-fi art. The speaker enclosure is made from one solid piece of elm, sectioned only at the rear of the speaker in order to hollow out enough material to create the speakers internal volume of air. Aside from being aesthetically pleasing and unique, using actual tree rounds as speaker enclosures is beneficial to the overall speaker design because it results in an almost seam-free cabinet, thick and acoustically dead enclosure material, and non-parallel internal sides which help to reduce unwanted frequency amplification and reverberation. This Instructable describes the unique process of how I built these specific tree speakers, and is not meant to be a complete and comprehensive guide to speaker building. I think that the appropriate question to ask here is not "why build speakers out of a tree", but rather, "why not"?
