WHY ?
Lorrie Matchett is doing in his 3rd Generation video this question,decreasing Amperage - under load - condition related !
'ideas' are ever nice,to work out these to technical and industrial NORM-devices harder and financial more expensive ,we - as developper - have to pay for the official process !
Zero US$ Brubacker/Matchett ,800 US$ Indrawan ,1000 US$ chardi :only small fraction from
related 100 000 US $ minimum costs for each device the technical normation process ( included UAL or TUEV/DEKRA approval ) for legal using ( device selling,device use and grid connection )
Prototyping and study 75000 US$ for such small cheap devices + 25000 US$ UAL/TUEV/DEKRA technical approval
This is independent from purchase/availability kind : gratis/donation - no profit- low profit - high profit/margin
When the technical device is the reazon for damages and/or injuries,the device producer/experimenter/ giver/ seller ( non/commercial ) is 100% for the losts responsible !
the social/economical/ecological target :
absolute minimum C.O.P. 10
in 20° Kelvin amplitude climate zones for 80 sqm living area ( conventional building )for 4000 W heat energy = 0° C outside and average 20° C room temperature
400 electric VA-/Watts spending
If on-grid by energy-mix 400 EE-Watts x PE-factor 1,8 = 720 PE-Watts / 80 sqm = 9 PE-Watts/sqm
compared
About PE-factor : energy source dependent , can be 3 f.e. coal based electricity generation or 0 by renewables
Here ' 1,8 ' the german mix from nuclear + coal + gas + wind + water + solar + biogas
Nearly Zero Energy Standart : 20 PE-Watts/sqm now in E.U. energetic new building obligation !
- Passive House Energy Standart : 10 PE-Watts/sqm in Ireland,E.U.-member,new building standart obligation !
10/20 PE Watts ?
By electric heater or chiller this can be by Primary Energy Factor = PEF
based by coal = PEF 3,0 :
3,3 electric Watts/sqm consume as Passive House Energetic standart
6,7 electric Watts/sqm consume as Nearly Zero Energy Building standart
or
based by renewables = PEF 0,0
theoretically ( no technical-mathematical limit )
33/333/.... electric Watts/sqm consume as Passive House Energetic standart
67/670/.... Watts/sqm consume as Nearly Zero Energy Building standart
CONSTRUCTION STYLE FREEDOM AND LIBERTY IS BY ECOLOGIC VIEW AND SOCIAL ORDER UNIQUELY PE-FACTOR DEPENDENT,NOT CONSTRUCTION/INSULATION MATERIAL AND THICKNESS
Thermo-grafical house imaging and blower door teste are not ecology indicating !
Only losts or consume leckage showing ! By PEF= 0,0 ecologic unimportant !
A PEF 0,0 energy source makes a 200 years old irish thermic uninsulated cottage easily to an 'up to date' energetic 'Passive House'
C.O.P. 10 x C.O.P. 10 cascade effect of heat/cooling systems decrease the house construction or energetic modernization costs !
With C.O.P. 100x a 1 cm thin bubble foil tent gets energetic 'Passive House'-standart !
C.O.P. 10 x C.O.P. 10 x C.O.P. 10 cascade even more !
Up to 20° Celsius negative climate zone = 40 ° Kelvin amplitude :
air/water heat pump DE3444610 and DE3212800 Rene Valkenburg
Hallowell acadia heat pump,technical concept 2020 ' open source'
Cold climate zone : - 20 ° Celsius strong winter peak
By 40° K amplitude the conventional 80 sqm building needs for 20° C average room-temperature up to 8000 W heat energy x PE Factor 1,8 =
14400 PE-Watts / 80 sqm x 10 PE-Watts/sqm Passive House maximum = C.O.P. 18
14400 PE-Watts / 80 sqm x 20 PE-Watts/sqm Nearly Zero Energy Building max. = C.O.P. 9
MDI ( Monolith Dome Institute ) writes about US conventional construction building heat need max :1200 ft area ~ 112 sqm 12000 Watts ~ 10 W/ft or 107 W/sqm
Climate diagram Miami/Florida and Chicago/Illinois comparison ,related average seasonal temperature !
Doing a look : Colorado,Boulder : Dec. average low 21° F ~ 6,12 ° Celsius negative

Snow-man feelings !
Not far from Munich's 28° F in Dec./Jan. ! Wet or dry - windy or windstill ?
Passive House energetic standart = 90% less energy consume 107 W/ sqm versus 10 PE-Watts/sqm in the US
with C.O.P. 100 x 99% less
Instead thermodynamic cycle devices also alternatively :
electro-dynamic devices,called " Resonator"
( ~ hot/cold Seebeck/Peltier/Thomson effect but with 90-99% Carnot-efficiency) :
Gerhard Beier,Helmut Reichelt,Joseph Yater as development pioneers
I have no physical and technical doubts about conventional air/air heat pump with seasonal average C.O.P. 3 to
improve to C.O.P. 12 and with Imris 2010 static generator C.O.P. ≥ 10 couple to reach an accumulated C.O.P. ≥ 100
state,
80 sqm living area air conditioning equipment, 20 ° Kelvin heat amplitude minimum satisfying :
4000 Watt peak
2 x 3000 W/ 10 000 BTU heat pump with gear + magnet motor for C.O.P. 12 improvement
each 550 Euros ( motor with Inrush Current Limiter )
and nominal 1000 Watt Imris generator for 500 Euros
--------------------------------------------------------------------------------------------------------------------
total 1600 Euros/+- 1875 US$ for 80 sqm all seasons air conditoning =
20 Euros( 23,5 US$)/sqm '(Ultra-)Passive House'- Standart costs
--------------------------------------------------------------------------------------------------------------------
( this clearly as mass production consumer end price,not for the prototypes : 300.000 US$ development costs for ready to commerce )
but I know that there is one less expensive way !
Idea : all seasons inflatable (translucent) bubble foil tent with C.O.P. 100 air conditioning ,
24/365 glamping society
Apis Core,ICON,WASP 3d-house printing
Polycare,Interbloc stone block buildings
woodframe,butlerprojects,conics,bhb.sbg.at(candian block-house style) wood house
Foldable portable building (Kalinowski),Power Profile Building,Leep Core
Who pays more than 250 Euros/sqm home-kit* value will get in future R.O.I. losts !
* : Not Nearly Zero,not Net Zero : Zero Energy + Zero Water Building infrastructure equipped
From russian space-shuttle MIR to earth use : Jugend Forscht project,90' : Eberspaechter et al.
portable 100 % closed cycle water system ( demo- prototype,TUEV-approved : 600 Liters per day )
600 liters/day compared
Home-mobile/Camper forum : as example one couple with 50 liter potable water consume ,for 5 days ! 5 liter per day and capita !
Flexibility : flyable ' inflatable bubble tent platform' !? Drone-technology incorporated
