Biography
Biospheric painter of the Farm Ark.  A place to live with all the treasures of the world growing around us, home in the world.  And as others have done for me I wish to pass a love of nature, science, philosophy, and agrarian life into the future for others.

Seconded, Im very curious about thermal mass and citrus.  Especially a vertical function which seems like it might make air flow warmer. Growing off season crops becoming important with climate change as well.

Howdy, I think USB cables have a max 5 Amp limit and most not rated that high?  So charging USB .5 - 3 Amp max usually.  Like Douglas said “Leery”, I would be as well as cable failure is a fire.  Might be looking for a different system, like solar recharge buffering/dump which changes loads to secondary systems (like heaters) once charge reaches max.  While your charging heat is generated in any battery system, then dump to secondary heater.  If you have a central heated area for battery storage this increases efficiency of the entire system.  A life of integrated technology requires large structural change… I’ve decided to place it in a separate building not a central living space.  Cheers

Hello Richard,  I’ve raised a few Dexters for the last 10 years or so.  Curious as to what your growing in your fields?  Often what you’re growing is more important than what’s eating it.   Bit of chicken and the egg.  Greg Judy’s excellent, Gabe Brown’s ‘Dirt to Soil’, great guides as well as ‘Stockman Grass Farmer’.  Dexters love to browse vertically and a way to increase feed is grow vertical.  A few trees, bushes high enough they can’t quite get to the top will give shade and and feed.   If you give them the best food the they’re happier, fields happier, fences are more effective.  Cheers

Wow, right on Brian.  Drip ring mulch with scotch broom on a nearly dead Marigoule Chestnut and Bouche de  Betizac in May.  Cut and dropped spring scotch broom 8-10 overlapping smaller brooms, and behold Chestnut revival.  Soil test assays suggest increased fungal cultures identifying them will take a bit.  Rereading ‘Edible Forest Gardens’ as well.  Thank you, very much.  Cheers.

Of course love, but the rest is a secret.   Ok, ginger leaf, Cuban oregano flowers, tea leaves, and Bearss lime leaves for our farms Earl Grey blend.   Cardinalflower is a new one, thank you  M. Ljin.  I adore new spices and ones we grow ourselves the most.  

Has anyone ever tried to put together a volunteer cookbook from Permies?   Cookbook with anecdotal excepts on how people in different places grow the ingredients?  Permies, has a truly unique good food as health genre with a miraculous diversity that I don’t see anywhere, perhaps?  If the world is a mess, offer it good food grown locally as the answer we know it is.  Cheers.

disposable, 12V is fine for a small RV or whatever, but anything that needs real, permanent power runs better on 24V and quality.



Great advice.  Anymore?  I’m in the middle of below grade room build for this exact purpose, as well as increased insulation to zero degree, regular freezer, fridge that will reside in that room.  Brands and models any advice greatly appreciated.  I like the buy in person with voltmeter and testing.  We did that at a moderately upscale appliance dealer and found a few probs, higher load draws, shorts, all kinds.
As well is Sol-Ark 15K worth $$$ vs MyGrid $$ 10K givin likelihood of solid state battery tech coming in next 10 years? Thanks, Cheers the micro grids.

OK, a quick bit of research implied that it isn't actually the clouds, but different layers of air at different temperatures slowing, speeding or focusing the sound. The clouds tend to form at different levels and are definitely affected by temperature.

Do we have any physicists out there)



My son and I bantered all summer about the “liquid atmosphere” , of Earth 🌎.   I pose that we are all vertically swimming through life.  He counters that he can’t hear me sometimes because his ears are clogged with air/water.  He did ask if clouds makes the traffic sounds louder.  Yes, clouds are a visual mark of temp change in atmosphere, and denser atmosphere reflects more sound wave.  We tested this with temperature, day/night, clouds and no clouds, used a small pocket laser to bounce off the clouds back to photomultiplier hooked to an EyePad.  Star gazing can be tough here in summer, gotta have a backup plan.  Eclipse last week, had em bouncing around for hours:).  Cheers

Fair and excellent point Sir Arthur.  Some work I do as work, and some work is to prevent my own entropy.  Have trouble telling the difference, yet winter heating is an excellent motivator.  I believe starting the fire with an high frequency oscillating vacuum pulling exhaust would fix the ash clean out as well locating the primary ceramic Venturi at the very front of the modified RMH.    Cheers.

Hello, a long summer outdoors constantly.  The house losses itself and we become the  garden, orchard, and forest, yet the drone of autos.  I’m in Christopher’s boat with a HWY about 2 miles away and elevated across a valley.  My architect uncle in the mountains of CA a long time ago suggested Dawn and Coastal Redwoods.  Curious much of Northern North America, Greenland, was covered in Dawn Redwood, Metasequoia during the Mesozoic and Cenasoic.  Not a short term fix but a complete wall maybe 70-80’’ in my lifetime, and taller for my son.  Planted on a Hugelkultur line of dead Doug Fir buried at 4-6’  to the surface and a second planted group 20’ in front of Taxus Baccata Yew’s, and Chilopsis Linearis Dessert Willow, all in a 4’ deep sub swale just a double dozer wide  road.  With a 2’ high 2’ wide burm down center.   Channels to prevent heavy precipitation runoff which may occur this year.  The Redwoods can be sheered when young to gain density, not too hard.  This doubles as a fire line in about 15-20 years.  I can wait for retirement, and I guess peace and quiet.  Cheers.

Exactly Kit!   If you only seasonally use a heating system and can scale it up or down as people do today.  They limited the air intake aperture as they showed and extended the burn time lessening wood consumption.  I don’t run my thermostat in the house at 26C all winter, 13-14C.  If I had only hand tools wood to burn becomes gold.  The thermal monitoring noted temps well above 20C would be too much for people spending the majority out of doors.  The real brilliance of Hypocaust is thermal buffering 2-3C naturally cooler in summer, and with RMH built central in the design the circulation could heat a large structure very efficiently.   Just a scale change to the RMH.   Rebar and lower lime in modern concrete prohibits higher temp direct heating with fire as it will degrade structurally when cooling/shrinking.  Instead I imagine a long small burn/exhaust chamber the length of limecrete floor with a thermal wall above it transferring heat to a second floor.  
Compared to digging 50+ meters at 60K for the modern geothermal systems pumping 3-4 tons propylene glycol under your feet.  Imagines if that breaks physically… if the limecrete breaks you can patch and it will get stronger.  Absolutely brilliant.  Cool people live longer, scientifically speaking.  Cheers.
