Been working slowly on solar designs for the house since moving in. Because of finances, the designs have pretty much remained on paper or just in my head.
On the upside, that has given me more time to develop the plans more effectively. At this point I think I have some highly efficient designs worked out. While the most effective designs are for solar heating, I am also working on other ideas.
One of the most promising, if radical, is a hybrid solar chimney with evaporative cooling, with water circulated from the well, which is quite cool. The idea is that, with enough heat to the solar chimney, that would cause hot air to rise, which would create a vacuum. If powerful enough, no electric fan would be needed. Just releasing the heated air would help greatly to reduce the need for cooling. Of course, this would be most effective during daylight hours and an electric fan would be required at night or on cloudy days.
One idea has eluded me until recently. How to circulate the water with the least power. Only the seed of the idea is present now but involves using two water reservoirs. An upper and lower. The upper tank would release water gradually through filters. Of course, bottom would catch it. However, the water would only be circulated back upward when the upper reservoir was nearly empty.
Still an idea in progress.
I have figured out how to make a thermosiphon system double as a solar chimney. Simply include sliding doors which would direct heated airflow to the outside in hot weather, inside in cold weather. Make it taller than the average system and include screens to keep insects out.
The fact is, I find most solar heating designs to be very inefficient and limited in application. I think much of that is because the marketers of the systems use old designs (solar chimneys date back as far as ancient Rome). They also market separate systems for different uses, rather than combining them.
In my case, in the long term, I am considering whether routing water through a thermosiphon would preheat water effectively enough before using a solar heater, only dumping into a standard water heater as a last stage before delivery. At least double to insulation on the final water heater. If nothing else, it would nearly eliminate the need to use gas to heat water from near freezing in winter.
That system would increase thermal mass for the thermosiphon, possibly making it effective even after dark for a while for cooling in summer.
All just thoughts for now.
