We have chosen the first photo on the basis of its importance in relation to the amount of energy collected and used per dollar spent. This system has been in operation on Camano Island for 25 years. In terms of today's cost (materials only) it likely is one of the most cost effective solar energy systems ever contrived. It does not have a solar storage system so it only collects and feeds solar heat during the day when the sun is out full and continues to produce heat in proportion to cloud density as long as the cloud cover is not too heavy. Below we have described the system as well as our evaluation and system improvement recommendations for anyone who would like to build or purchase a similar system. 
 
This system has 2 collectors, constructed of 4' X 8' galvanized metal boxes with a horizontal baffle placed in the middle. A fan provides air from a ceiling mounted vent inside the residence. The air enters from the bottom on one end of each flat black box. It is then heated as it makes its way horizontally around the baffle until it reaches the end of the panel where an 18" section of the baffle is removed, where it then rises into the upper chamber. The air then continues to heat as it makes its way horizontally again and returns to the same end of the panel from which it entered, but to a feed vent in the top chamber that is connected by a duct to another ceiling vent. 
 
It is a shame that we don't see more of these as this system can save a great deal of heating cost by providing free heat from the sun.
 
The system fan is controlled by a differential thermostat that is set to the desired home temperature. Whenever the heat of the collector is hotter than home temperature and when the thermostat asks for additional heat the system fan turns on. There are several design elements that can be improved: The Lexan panels should be ultrviolet resistant. Double glazed panels can be used in windy or very cold regions but single glazed may be nearly as effective and have extended life in most areas. The panel corregation should be mounted vertically to allow drainage. To be most effective, the vents from this system should be mounted in a central area of the house. The hot air feed vent should idealy be placed at a low elevation on the wall or in the floor and the air return vent should be also at a low elevation but on the opposite wall far from the feed vent. This creates a circulation of warm air since warm air rises and cool air drops. It will work however as this one is set up, with both vents mounted on the ceiling. Our evaluation of the system is that we think it has a high degree of merit and rates very high in terms of cost and effectiveness.  Other items that could be improved: Provision should be made for draining accumulated condensation which causes rust and eventually destroys the structural integrity of the box. This can be simply addressed by providing small drain hoses on the lowermost corners of the box. The box can be fabricated from cedar as well using cedar throughout. Do not use oil base paints or paints or plywoods, fiberboard or oriented strand board that may contain contaminants that may vaporize when heated!! A good quality latex based metal or wood primer (as required) should be used under a good quality latex based flat black paint. Vent the home thoroughly and often during the first week of operation. Be sure your home has a fresh air supply, even if it means opening windows on each end of the house slightly. Another way of achieving a constant supply of fresh air is to introduce a percentage of outside air at the air return vents of the system where air is vacuumed up by the fan or fans that feed the system. Install an adjustable vent on the fresh air supply.
 
Additionally, the system can be enhanced by adding thermal mass to the home's interior. This mass can absorb extra heat during the day and release it at night. Water columns made from fiberglass, galvanized culvert pipe (rubber coating can help reduce any possible rust), triple layers of sheetrock, heavy furniture or any massive objects will assist. In areas where summer nights are cool and days are hot, a separate fan switch can run the system at night, bringing in cool air which removes the thermal mass heat and this will assist in cooling the house in the day. Even without thermal mass storage, this system is worth installing. Panels can be mounted on or built-in to the roof as these are, OR they can be mounted on a ground structure or frame that has been designed to withstand very high winds, since it only takes one storm to lose your system. They can even be integrated into the exterior south facing wall of the home, as long as they are not vertical. In extreme north or extreme south global locations, vertical integration may be desireable. In most regions the sun remains vertical or high in the sky during spring and fall and a compromise angle is needed to collect solar radiation between these seasons and winter when the sun is low on the horizon. At latitude 46 an angle of 45 to 60 degrees from horizontal is good. A rule of thumb is latitude plus 15 degrees. This rule does not hold true for maximum PhotoVoltaic energy (electric systems) however, as with net metering and air conditioning you want to collect as much summer energy as possible, thus, a rule of latitude minus 10 degrees works well here in Puget Sound and most areas.

The projects below are customer designed and installed and therefore, system architecture, design and installation are attributed to the owners. These particualar projects that are near but on oposite sides of Mount Baker, Washington. Mount Baker is another but silent volcanoe near the Canadian border. This is truly a beautiful area with pristine forests, meadows, lakes and campgrounds. For tourist attractions see Bellingham, WA, the San Juan Islands, Whidbey Island, Camano Island, Seattle, Cascade National Park and the Olympic National Park on the Web. Remember the beer drinking bear on the National news?.. Well, this is the place! In Western Washington, due to the extreme heat we have to drink a lot of beer to keep cool  :-)  In actuality we receive 70% of the solar radiation that Los Angeles does.

AN AMBITIOUS PROJECT ALONG THE FAMOUS SKAGIT RIVER -- WELL KNOWN FOR ITS ORGANIC AGRICULTURE. YOU HAVN'T SEEN OR TASTED BLUEBERRIES UNTIL YOU'VE TRIED THE SKAGIT RIVER VALLEY BLUES!!

Jeremy Baker is a Certified Permaculture Designer. Jeremy raises organic and sustainable gardens in the Skagit River Valley near Hamilton, Washington. He stands beside his renewable energy battery bank which will is fed by a photovoltaic array and eventually an Aeromag wind generator. Jeremy plans to share his knowledge of organic gardening, permaculture (which is an easier healthier way to grow fruits, vegetables, poultry and livestock) and also to provide examples of renewable energy. Jeremy has a lot of advanced ideas about a healthier lifestyle. He and his companion Cindy have a number of projects.... In this day and age of health problems, poor nutrition, overweight concerns, immune disorders, biological and chemical food contamination, as well as air and water pollution, their ideas for growing your own food may become mainstream as we learn more about the causes of our ill-health! His ideas also revolve around the concept of planting native trees and plants that provide healthful benefits to humans, wildlife and the total ecosystem. These usually require little maintenance. Jeremy and Cindy are installing supplemental solar heating, solar and wind electric power, composting facilities and they have a special contract with the to help restore salmon habitat by growing native tree and shrub species along the Skagit River. Jeremy also accepts volunteers and hosts workshops and plans to have permaculture training programs in the near future, when he has time. This will become a priority for him in the years to come. Jeremy can be reached at canoeh2o@valleyint.com or at 360-826-4309. The modest fees he charges for this instruction can improve the quality and longevity of life itself. Don't expect the Sheritan or the Holiday Inn -- this is a working farm, and it is likely to be some time before Jeremy Baker and Cindy Bjorkland will have the farm fully organized. BTW, Cindy works for the U.S. Forest Service and has a lot of knowledge about sustainability too. If you would like to help with this worthwhile project and learn in the process, write or call Jeremy for additional information. If you can be of help to them and learn in the process, maybe, as a reward, you might be able to persuade Jeremy to take you on a tour or trip in our local area. The beauty and closeness to nature in the Pacific Northwest is truely something to behold.

Jeremy and Cindy's new home will have a lot of conservation features including High R value insulation, sustainable wood heating and passive solar heating supplement. Jeremy also is working on a solar hot water system.

ACHIEVEMENT

What constitutes ‘Achievement?’

When it comes to life goals it is ‘accomplishment’ that counts. ‘Buts,’ ‘if onlys’ and ‘what ifs’ do not count other than for our educational edification. Things that might have been, or negative memories and attitudes from our past experience do not count in totalling our achievements. However, they can have great merit if we apply the lessons of our past in a positive and constructive manner toward establishing a new path to overcome our frustrations and find new roads around the obstacles that prevented us from achieving our goals. This applies to those with disability, illness or health issues as well as those in good health: Achievement is a result of our attitude and our commitment, and also a result of accepting responsibility for our own failures. We must believe in our abilities and what we CAN ACHIEVE,’ rather than to dwell on what we have not achieved or to dwell on fears that we may not achieve. We must find a way around our limitations, especially negative attitudes in our thinking process that tell us it can’t be done. Too often, we limit our own success with preconceived beliefs. There is always a path to succeed provided our goals are realistic. Finding something that we value and believe is truly worthwhile and really worth doing is the prime consideration -- then sticking with it and never giving up. It is ‘persistence’ that leads to success and the results of achievement. Real achievement and happiness may be in helping others and in trying to make the world a better place for everyone...

If a goal is unrealistic, it may need to be modified. If we are convinced that our goals are realistic and good for the world, our families and our own well being, we must be willing to try more than one road to that destination. And, we should always be willing to consult with others of high moral character to ascertain the true value, validity and worth of our goals.

We won’t be able to ‘jump over a mountain,’ but we may be able to ‘gradually’ climb over it by crawling, gripping and pulling our way up to the top and over to the other side! Those who are willing to try, to learn and to overcome the obstacles are the Achievers!

By the way, anything we can learn from others who have been down our path before will make our efforts far easier. Reluctance to seek professional advice or our stubborn resolve to do it 'our own way' may cost us a lot of money and lost time. Seek out the best knowledge and solutions from those who are in the know. Realize that there is little benefit in reinventing the wheel (unless we want a square one :-). The belief that our own instincts or insights are the only correct ones may cause us considerable grief and disappointment. Educate one's self and prepare one's self well before emabarking on a major undertaking or profession. Professional training and education will save us a lot of grief! And remember, when it comes renewable energy: As applies to permits and safety procedures, there are usually sound reasons for their implementation.

"Yes, although your burdens are great, I am here and I am listening. May all in my kingdom love one another and live in peace --  together!"......... God
