Guide To Free-Energy Devices, Zero-Point Energy BubbleWrap Window Insulation Search The Renewable Energy site for Do-It-Yourselfers Installation Cut the bubble wrap to the size of the window pane with scissors. Spray a film of water on the window using a spray bottle. If you have trouble with the bubble wrap separating from the window when the film dries, you can try adding a little Glycerin to the water, but this probably won't be necessary. A few small pieces of double back tape can be helpful on really stubborn windows. The bubblewrap can be installed in the fall, and removed in the spring. When you take the bubble wrap down, put a small number in on the upper right corner of each piece of bubble wrap, and write down which window that number goes with on a piece of paper. Some places to get bubble wrap: Suggestion from Pat: "Bubble wrap small bubble and large can be had for free by contacting furniture retailers or rental shops.

Cheap/Free Window Insulation Bubble glazing Whenever financial aspects take precedence - availability of resources seems to be a disincentive for progress in sustainability and conservation. When we can afford more – we simply waste more, without even admitting for consideration that Earth is a system of limited resources. The opposite direction on the other hand – aiming to improve quality of life while accepting severe limits to every resource including money – seems to be one of the greatest incentives for creativity and innovation. It is a part of human nature – we don’t even begin to invent things unless we really need them and we don’t think about ways of conserving resources unless their supply becomes limited. Bubble glazing idea emerged from a pressing need to become more comfortable in winter combined with severe budget restrictions. Double glazing is expensive, heavy and does not really represent a good value for money. For details please read the full article.
Énergie libre & plans de moteurs à énergie libre. Fabricating a Heavy-Duty Rocket Stove Rocket stoves are small efficient stoves that can produce a hot flame with only a few small pieces of wood. The reason it is called a rocket stove is because when wood is added to the fire the flames create an internal draft. As the draft is created, the fire begins to produce a jet of fire coming through the stove pipe. The stove flame eventually becomes so hot that it produces very little smoke. These stoves were created out of necessity in third world countries to cook small meals and have recently become more popular as a do-it-yourself camping stove.

Make your own biodiesel 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 Veiga THANK 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.
How to Make an AC Arc Welder Using Parts from an Old Microwave, Part 1 In a previous article, I demonstrated an Arc Welder made using parts from old microwave ovens. Here is part 1 of 2 on how that arc welding machine was made, and how you could make one too! This is the first of two parts on building it, focusing on the modification of the transformers. WARNING: Stick welding, and/or the modification of a Microwave Oven Transformer (M.O.T), can be very dangerous and presents risks of UV radiation, shock hazards, burns, fires, fumes and a multitude of other risks. In a previous project, I melted the lead wires on my first metal melter. The arc welder made sparks fly, but in the end, it wasn't enough power to make the metal stick, and the pieces of work would break apart with very little effort. If I tried pumping more power into the welder, the wires would overheat and melt. So to address this challenge, we'll be using 2 MOTs (Microwave Oven Transformers), because more transformers means more power! I used electrical tape to make sure the coils stayed tight.
Home-made Hydraulic Ram Pump Home-made Hydraulic Ram Pump This information is provided as a service to those wanting to build their own hydraulic ram pump. The data from our experiences with one of these home-made hydraulic ram pumps is listed in Table 4 near the bottom of this document. The typical cost of fittings for an 1-1/4" pump is currently $120.00 to $240.00 (U.S.A.) depending on source prices, regardless of whether galvanized or PVC fittings are used. Click here to see a picture of an assembled ram pump Table 1. All connectors between the fittings are threaded pipe nipples - usually 2" in length or shorter. Conversion Note: 1" (1 inch) = 2.54 cm; 1 PSI (pound/square inch) = 6.895 KPa or 0.06895 bar; 1 gallon per minute = 3.78 liter per minute.

Assembly Notes: Operation: The pump will require some back pressure to begin working.
Fabriquer une presse à pellets Publié Lundi, 12 Octobre 2009 10:10 Faire sois-même ses pellets peut donc s'avérer vite très rentable dès lors qu'il nous est possible d'avoir la matière première à bas coût (voir nul!). Mais pour cela il faut donc un pelletiseur (ou presse à pellets, ou encore extrudeuse à pellets). Les prix pratiqués actuellement sur le marché font froid dans le dos et sont le principal frein à l'achat de ces machines. Sur quoi sont basés ces prix? Comme nous l'avons déjà vu, il existe 2 types de presse à pellets, les "flat die" et les "round die". Nous allons donc réaliser ici une presse "flat die". Le disque pré percé (matrice) tourne à environs 750tr/min, les rouleaux sont fixés sur le disque et tournent également, par contact de ces 2 éléments. Ce qui est important dans votre choix, c'est la taille de la matrice. Mon choix s'est donc porté sur un diamètre 200mm. Commande de la matrice et des rouleaux chez pellet-mill.de, livraison rapide. Tout le reste est issu de la récupération de matériaux.
