My name is Brian Walker.  I was born in 1982.  I am a student of Chinese Medicine.  I am working to develope a permaculture farm in rural central New York State, where I hope to cultivate medicinal herbs as well as subsistance crops and livestock.  There is ample space to eventually transition the farm into a health retreat and venue for hosting community events, lectures, workshops, etc.  In the meantime, I am finishing my graduate program in acupuncture, herbology and Chinese medicine in Manhattan.  I live in Brooklyn most of the time, and bus upstate during breaks and some weekends to engage small preparatory projects on my land.

I am legally blind.  I lived in China for four years.  I play fingerstyle guitar, flute and drums, as well as sing and compose my own music and lyrics.  I enjoy strategy ganes such as wei qi and chess.  I cook often and with passion.  I am here to learn, to explore and to meet kindred minds and hearts.

Well met!

Thank you, Anne!  I'll try to contact the library.  If it's already recorded, it would merely be an issue of getting it legally reformatted to digital audio.

Indeed.  There is also the challenge of interpreting all of the graphical content and tables into an aural delivery.  No simple task from any perspective, but I do feel that demand for this book will revive as Permaculture continues to demonstrate solutions for heretofore insoluble problems.  One can dream.

I concur!

This would be the kind of project I think we'd need to crowd fund.  Perhaps we could contact the publisher with a copyright proposal.  I'm legally blind and any visual input is tedious, to say the least and heavily dependent on fickle text-to-speech software.  Good to know there might already be a support base for such an endeavor.

Thank you, Paul.

I, too, have land that's in need of construction and hope to develop along parallel or convergent lines with Wheaton Labs.  I'd like to keep horizons open and would enjoy sustaining a casual dialogue.  I hope to demonstrate how ecological health directly and explicitly substantiates individual and social health.  Hopefully, I'll make it to one of your events in the near future.

For the nonce,
Thank you for such inspirational work!

Hello Paul, Jocelyn, or whomsoever might be disposed to respond,

I'm approaching the end of a graduate program in Chinese medicine.  I am currently brainstorming prospective initial practice models and am curious if you might approve of a small, board-certified acupuncture, body work and herbal medicine practice in the context of the lab sites.
I am also an accomplished cook, and could offer a "form meets function" cuisine that is resource-adaptive, of gourmet standards and is adjustable anywhere from nutritionally excellent to directly medicinal.  What are your prospective interests in hiring kitchen help in 2019?

I shall be certified and licensed to work by summer of 2019.
My program title is masters of science in traditional Oriental Medicine, or MSTOM, at Pacific College of Oriental Medicine, NY.

Thank you for any thoughts you may have,
Brian

Hi Jeremy,

I don't know how quickly Geoff's tank would heat up.  It seems that all the hot air from the heat riser goes directly into circulation around the hot water tank.  Geoff seems to imply that positioning the tank horizontalally

forces the hot air in a spiral around the tank.  I wonder how re-positioning it vertically would influence this airflow.

I know little about welding.  I'm trying to resolve the design, first, then I'll approach some friends or family that weld (I'm legally blind or I'd learn :)
As for materials, I've got a tank and will probably purchase the 4" dragon heater precast core.

I'll do a modified design plan drawing and post it soon.
I'm thinking of Geoff's system, only vertical so it will siphon.  This will, however, require my elevating the tank significantly, or sinking the stove in order to establish the vertical siphon gradient.

Thanks, Jeremy,

I was, in fact, worried about coil flow...it does make more sense to keep cooler water at the bottom!

If I were to use Geoff Lawton's design per his youtube video (link below), and if I kept the coil horizontal as his is, would the thermal siphon still function?
https://www.youtube.com/watch?v=1oDpmmsqHwQ&t=628s
There's a diagram at 10:31 position.

That is to say, if I still elevated my tank above a horizontal coil and used an open hot out line flowing back up and over the rim of the tank, would the hot water still siphon as effectively along a horizontal coil?

Here's a drawing:

Also, because Geoff's system is essentially a "double boiler," is it safe to assume the water therein will not flash to steam?  In a system where the coil makes direct contact with the barrel, is there any chance of it flashing to steam beyond the speed at which hot water can be propelled out of an open-ended coil outlet?
I should probably make a miniature, too, to see what works best

Thanks!

Many thanks, Jeremy!

Your good advice is duly noted.

I will experiment with the second plan.

I will likely arrive at questions along the way and will report successes and failures as they occur.

Thank you,

Hello all,

Just checking back to see if anyone might have any feedback on my last post.
Hopefully the drawings are not completely indecipherable.

Thank you all!

Hello all,

I am trying to design a rocket mass hot tub and come in search of advice:  Thank you!

I have attempted to post a drawing of my basic concept, labelled "hot tub plan 1," but if it fails, here is a synopsis:
It would be an outdoor system.
I hope to create a heat cyphon with a copper coil positioned around the barrel of a 4" j-tube system, and with its ends communicating to tank aperatures of high, hot water inlet and low, cool water outlet, respectively.
I would position an IBC tank so that it was conductively heated by the rmh's exhaust system inferiorly while being ciculated with hot water from the ciphon.  The tub's sides would be insulated but its top would remain open during stove
operation.

Here are my questions
A. First of all, is this a sufficiently open system to be safe with a copper coil?
B. Secondly, Are there resistance variables defined by water weight that affect the safety of such a system used with a nearly full 275-gallon IBC tank of water?
C. I would also like to install filters on the interior of the tank over each aperture to prevent debris from accumulating in the coil.  Would the added resistance of a thin, non-insulative membrane contribute dangerous resistance
to water flow through the coil?
D. How do I calculate coil tubing diameter?  Should it be consistent between outlet and inlet?
E. As drawn in the image labelled "hot tub plan 2," Would it be desirable to elevate the tub enough to allow cool outlet water to issue from the tank bottom at the same level as, and feeding into the coil's top?
Would the resulting water weight be sufficient to push heated water down the coil and back up and out of a spigot overhanging the rim of the tank by a few inches so that it could act as pressure-relief and temperature gauge as it passes
through the intervening air between siphon and tank?

I am interested in using one of the 4" precast refractory j-tube cores from dragonheaters.com
http://www.dragonheaters.com/4-dragon-burner-rocket-heater-core/

I have searched and found nothing specifically devoted to this topic, but please forgive my oversight if this has been previously covered.
I welcome any advice, criticism or precaution.

Thank you kindly,
Brian
