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.
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.

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"?
