Micro-grid : off-grid electricity-grid and off-grid water-grid

Electricity -grid : the simplest way but also the most expensive way actually :

battery-set + FE-generator wind,water,photovoltaic - current and stream-  converter and fuel-gen-set as backup
Battery-set = DC output battery + appropriate charger + by AC appliances : DC/AC  inverter

As commercial scheme/example :
http://www.geolitesystems.com/ecosys.html

Wind/aeolic system :
http://www.poc21.cc/30-wind-turbine/
Only the " turbine/rotor" basic costs !     + tower +

electric generator/alternator :
1000/750/500 RPM and nominal Watt max. output ?

= min. 500 USD for the ready-to-use wind system ;

same price level but less tower costs : water flow/stream converter

fact is that it is a motor-generator concept with
electric motor RPM/torque step down to electric generator lower RPM
~ 4:1 ratio in this demonstration model

Resource use
A "typical household" in the U.K. uses 3,000 kWh of electricity per annum for lights and appliances alone, (2), about 36.6 kWh/m2/year just for electricity. The Autonomous House, by comparison, uses only 8.5 kWh/m2/year of non-renewable energy for its total energy needs, or 1,500 kWh of mains electricity.
Over the winter of 1994-1995, from the end of October to the end of February, the house used 315 kg of wood for space heating, which represents about 1,400 kWh of delivered energy, or about 8.0 kWh/m2 of heated area. The temperature in the living room reached a low of 16oC in mid-January, 1995, and then rose to a maximum of 27oC in the very hot August of 1995.
Water consumption was 34 litres per head per day, made up of 21 litres of cold water and 13 litres of hot.
These figures can be compared to an average U.K. house as shown in the table below.
Annual delivered energy and water consumption

Autonomous house
1400 KWh space heating
1900 KWh water heating
by optimized C.O.P. 10x heat pump

= 3300 KWh/10 = 330 KWh electric energy consume for heating

+ 1200 KWh for lights,appliances and cooking

= 1530 KWh total electricity consume per year
- 1600 KWh solar electricity
______________________________________________
= by definition : a NET ZERO ENERGY BUILDING

This compares to a 200 W net output permanent working electric generator and  5 KWh electricity storage device

8766 hours (= 1 year) x 0,2 KW = 1753,2 KWh electricity generation per annum

for on- grid households


To reach the ZERO ENERGY BUILDING stage and "off-grid" = all seasons uninterruptable energy generation

For this condition : 1 KWh net output permanent working electric generator and 10 KWh electricity storage device
Cause : hot water and space heating energy demand in cold seasons multiplies the average daily consume !Also the daily 0:00 hour to 24:00 electricity consume shows low - middle-high provider to off- grid-load demands for each household !
Urban Nomads = RV/mobile-homes user   know this sustainable and logical = by priority  use of resources



My way : instead this "NegaWatt"-Prototype ,well constructed,with 176 sqm floor area
I would choose the half area by tailing :
176/2 = 88 sqm  ~ expanded family home
but 48 sqm conventional and 40 sqm "morphed" ~ 100 sqm
ergo equivalent conventional 48 +100 = 148 sqm floor area
Less space heating energy and floor area need  !
Kutzner : 30 sqm container-box-house foldable to 90 sqm

1900 KWh water heating : shower-loop ? Economic shower-head ? Waste water heat recuperation ?
                                               The uncontroled consume can be reduced ( included recirculation) up to 75%

                                               Shower : f.e. www.hamwells.com their concepts             

               On youtube several vids about DIY- water heating and saving devices     
1900 KWh per year means 5,2 KWh per day : 0,52 KWh electric by C.O.P. 10x heat pump
We have often to ask ourself : Should I ? Must I ? Will I ? Do I ?

Power-to-weight and Power-to-costs ratio  :
fridges are mostly equiped with 100 W compressor-motor
The ex-patent-department of Siemens supervisor Dr.Wolfgang Volkrodt wrote that the right conventional bike
electric assistant wirh 100 W work potential nominal is sufficient
The taiwanes inventor Li Yng discloses in his publication about the use of 4 mini-motors wirh +- 10 Watt each

Ampere Motor : 220 KW 30000 RPM 10 Kg  = 22 KW/ Kg Volts ?
Let us diminuate RPM and maximize the material :
                             220 KW 15000 RPM   20 Kg
                                              7500 RPM   40 Kg
                                              3000 RPM   100 Kg
                                              1500 RPM   200 Kg
                                                750 RPM   400 Kg
                                                375 RPM   800 Kg
                                               187,5 RPM 1600 Kg

187,5 RPMs are the range for slow running generator concept,750 RPMs the general nominal rotation number of aeolic force converter = wind generator,3000 RPM are the grid-net 50 Hz analog fixed rotations .

Let us calculate the possible material transforming costs in mass production of the Li Yng transmission :
we take the 15000 RPM weight of 220 KW/20 Kg but now for 4 x 10 W =
10 W/ 220000 x 20000 Gr. = +- 1 Gram per 10 W motor

When we enter the alibaba electric permanent magnet dc motor selling sites we see the actuall average price for
low rpm motors in the 75 US$/ Kg for the ready to use machine

1 Gram /1000 Grams x 75 US$ = 7,5 US$cents for each motor  !
30 US$ cents the 4 electric motors + the transmission costs


1 100 W fridge compressor motor with ? rpm : ? costs
1 100 W Volkrodt electric assistant with ? rpm : ? costs


When we enter the german engineer Helmut Schiller his site schillergy.com we see that for his " scooter motor"exampl3 he needs +- 0,5 Kg/KW active material + more or less the same passive material ( reference : UQM )~ 1 KW/Kg in the 48 Volt DC range and 3000 RPM
Schiller motor development from 1994 ~ 2020 Ampere Motor propaganda
So we can reach for fridges and electric bike assistants the 100 W,/1 KW x 75 US$ = 7,5 US$ gross selling market price level,knowing that the alibaba neodym magnets are probably calculated (N40 average) with 40 US$/Kgand alternatively in future same magnetic specification will become available for 15 US$/Kg prices

We look for the #6 GB " Autonomous House" specific consume numbers :
1400 KWh for room heating ( by wood stove)
1900 KWh for warm water
1200 KWh for lights,appliances,cooking

dividing this in warm and cold season

1400 KWh        -

950 KWh       950 KWh
600 KWh        600 KWh


water( and heat savings)
1400 KWh      -

350  KWh    350 KWh
600  KWh    600 KWh

We halve the 176sqm( to GB average) and double the KWh/sqm ( from average  in-room 15° to 20° in winter)and use optimized heat pump with C.O.P. 10,room heating and water heating

280 KWh          -

  35 KWh        35 KWh

600 KWh      600 KWh


We optimize electric motor efficiency and heatelements
280 KWh        - 

35 KWh       35 KWh
400 KWh     400 KWh

So we need in winter period 715 KWh electric power and in summer 435 KWh electric power,available by solar
photo-/thermovoltaic conversion

Total average yearly consume :
1150 KWh electric ( 1995 they got in average with installed 2,2 KW solar cells divided in 20 sqm field area 1600 KWh per annum = 1150 KWh - 1600 KWh = Net Zero Energy Building )

715 KWh divided by 183 days ~ 4 KWh electric generation /12 hours = 350 Watt  /24 hours  175 Watt

The private consumer household needs :
a permanent/periodically working generator up to 1 KW range and for the parallel use of electric appliances a battery-set for accumulated Watt-inrush/peak demands up to 2 KW

Instead ( thermical/chemical/electrical/magnetic) battery-set a waste wood-combustion generator for high demand over-bridging also possible !

Waste wood cogeneration system with C.O.P. ≥ 1 possible ,near gas-heat pump 150% efficiency .












we take 1 sqm thermovoltaic panel ,with 1-sun 45% conversion efficiency


in 1400 KWh solar radiation wattage per annum and climate zone we get 630 KWh x 0,7 (fixed installation losses)= 450 KWh ac electric power


with 2x 1 sqm thermovoltaic panel we get 450 KWh x 2 = 900 KWh as 1-sun gain


these 2x 1 sqm panels get each 1x mirror ,which equates 2-sun,which amplify the conversion by min, 1,6 = 450 KWh x 2 x 1,6 = 1440 KWh ac electric power per annum
