DIY Heat Recovery Ventilator (HRV) Plans Search The Renewable Energy site for Do-It-Yourselfers DIY HRV Plans This is an article that was published in the 80's and provides good detail on building a Heat Recovery Ventilator from Coroplast sheets. The HRV is not an easy environment for materials in that water and even ice may be present at times. Build a Simple Solar Heater After walking into my workshop one December morning and feeling a bone-chilling 10 degrees, I decided to install a heating system. Given the rising costs of propane and my family’s environmental concerns about using nonrenewable fossil fuels, a solar solution seemed fitting. I’m a retired aircraft engineer, but you don’t need a similar background to tackle this project. In fact, a solar hot-air collector built into new construction or added to an existing building can be an easy and inexpensive heating solution. Following the simple principles and plan outlined here, you can heat your workshop, barn or even your home with free heat from the sun. If it works here in Bozeman, Mont., it’s bound to work wherever you are.
DIY Solar Projects Part 2: Simple All-In-One Solar Water & Space Heater One of the biggest challenges people face when looking to incorporate solar systems into their homes is the cost. The systems themselves, although (slowly) becoming more affordable, are expensive when purchased commercially and the installation costs can be even more so. DIY solar projects are a great way to take advantage of the free energy provided by the sun for a fraction of the price of a manufactured system. Gary Reysa of Build it Solar has amassed a huge collection of solar energy projects for do-it-yourselfers on his website, including this incredible solar water and space heater in one system. He built this for about $2k out of all high-quality, readily available materials. Gary’s objectives with this design were to keep the system simple and inexpensive, make it easy to construct for average DIY’ers, use materials available in most local stores, and produce an end result that is not only aesthetically appealing but one that requires little maintenance and lasts a long time.
The Jean Pain Way - PermacultureNews.org In the book Another Kind of Garden, the methods of Jean Pain are revealed. He spent his entire short-lived life studying brush land and forest protection, specifically fire prevention, alongside his wife Ida. These studies led to an enormous amount of practical knowledge for composting, heating water, as well as harvesting methane, all of which are by-products of maintaining a forest or brush land with fire prevention techniques. While this knowledge is applicable in many instances, it is worth remembering that the root of all of this knowledge lies in forest preservation. All of the activities described below are by-products of that process.
Build a Fresnel Lens Solar Cooker for Free The tremendous amount of heat that can be generated by bringing the light of the sun to a focal point through a lens is pretty amazing. Did you ever use a magnifying glass to burn ants when you were a kid? I can’t say that I ever did…but I did get to use one to burn leaves for a science class experiment. DIY Solar Projects Part 1: Build a Solar Heater Using Recycled Cans A few months ago we did an article about Cansolair Inc’s brilliant solar home heating solution that uses recycled aluminum cans in a forced convection solar heating unit. These units work by pulling cool air from a room, passing it through a panel of aluminum cans that are heated by the sun, and blowing the heated air back into the room. Just about anyone can make one of these heaters, and they can be constructed from mostly recycled materials. This is a fairly simple project for DIY’ers that can be used to heat a home, a greenhouse, a camper, a garage, a cabin, or just about anything else you can think of. Once the unit is built, all you need is an outside wall for it to sit against that will get plenty of sun.
Wood Burning Electricity Generating Stove INDIGIRKA-2 During the process burning the stove generates the direct current of 12 volts and power not less than 60 watts, which is transferred to the control block and then to the external clamp outlets. The electricity generators enter stable operation mode 12 – 15 minutes after fire starts. Generators supply enough energy to light 2-3 energy-efficient bulbs, charge notebooks, cells, tablets, cameras, watch a portable TV or listen to radio, and so on. It’s not very much – but in emergency situations it will allow you to operate vital and lifesaving devices, and use ordinary wood, pellets, charcoal as fuel. You may want to keep it safe in your backyard, just for a case.
Homemade Solar panels At the end, the solar absorber is painted black and placed in the diy solar panels casing. The casing is covered with plexiglass that we attach to the frame and thoroughly corked with silicone. Polycarbonate / plexiglass is slightly convex in order to gain greater strength. You can see installed solar absorber without plexiglass in picture 18. Complete solar collector is shown on Picture 19, and finally, installed solar system can be seen in Picture 20. The following page shows complete specification of parts and material needed for building diy solar panels.
DIY Solar Water Heater For About $30 In PVC Supplies And Paint Did you know that 70% of your home energy cost are on water heating? In response to this, a Brazilian Eco Designer developed a low cost and intelligent method of reducing energy costs and preserving the environment reusing waste. He created a simple passive solar water heating using PET bottles and and some PVC pipe. According to his calculations this is an extremely low cost and safe project that you can do yourself at home. This project has become popular on the web and has been adapted to homes and even schools.

DIY SOLAR: Inexpensive Homemade Sun Tracker Maximizes Solar Panel Efficiency One of the biggest limitations of static solar panels is that they are only at maximum efficiency while the sun is shining directly on them. If panels are able to move and track the sun, they will receive greater amounts of sunlight during the day, making them 30-50% more efficient than unmoving panels. You can build your own inexpensive solar tracker by following this concept from bwitmer on Instructables. For a class project, he decided to try to build a photovoltaic tracker that was both cheaper and more sturdy than versions available for purchase. The concept he came up with is a panel mounted to a frame attached to two bike wheels, which are mounted to a larger frame. The wheels and panel are moved by a 12 volt linear actuator.
Installing your own small, remote off-grid solar system by Jeffrey Yago, P.E., CEM A typical residential-size solar system installation will involve properly sized and installed AC and DC electrical wiring to reduce the risk of electrical fire, a proper grounding system to prevent shock and lightning damage, proper battery installation and venting to prevent gas explosions, and a properly installed solar array to maximize performance while avoiding roof damage. In almost all of my past articles I have described many different types of solar power systems, but did not go into detail on how to install them yourself, since most systems should be sized and wired by licensed solar professionals. However, the Backwoods Home website continues to receive many e-mail questions related to smaller do-it-yourself solar projects for remote weekend or vacation cabins in areas not served by power lines. Otherwise—don't try this at home.

DIY Solar Powered Air Cooler for $15 There are many ways to heat with solar energy, but cooling can be a little more of a challenge. Here is a way to make a cheap and simple solar powered air cooler using a foam ice chest, PVC pipe, and a fan. The fan blows air across ice in the chest, and the cooled air is blown out the PVC pipe. The block of ice used in this example lasted for about 10 hours inside the chest. (See the bottom video for making ice “off the grid”)
