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.

MALEVIL FARM: JOHN STERRITT AND MARCIA DUVALL HAVE AN INTERESTING SELF-SUFFICIENT FARM NEAR BELLINGHAM. THEIR PROJECTS OFFER
A LOT OF VALUABLE INFORMATION THAT THEY ARE WILLING TO SHARE. Please note that John and Marcia are currently rebuilding this
site.
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.
