per capita : basic alimentation 360 gr. bread 36 gr slices ,5 x per day 2 x 36 gr
the minimum 1000 kcal reached

agricultural land need 375 sqm ( 4 tons wheat per ha) + 125 sqm fallow ( 3-4-fields-agro-economy)
Instead butter liquid olive-oil/sunflower oil  et cet. ( Oil seed) 80 gr. per day ~ 720 kcal

Cow or sheep milk (alternatively : soja-,rice-,almond-,) 0,5 liter per day
Fruit( orange,citrus,apple,...)  or vegetable juicy ( carots,tomatos,.....) 0,5 liter per day

Fruits and vegetables : green house growth (~ jovoto : food& water&shelter : 300 US$  costs list)


On bread : peanuts butter,almond butter,marmelade (quinces,orange,citrus,..) and jams

                   cheese and cooked/raw ham,salami

Not vegan-/vegetarian philosophical orientated the physiological nutritional values gives us a "vegetarian/vegan"-orientation : by aliments nutrition values !


2200 kcal are easy to reach with "soft weight eat: gourmieren ",and the agricultural land need per capita : 1125 sqm total !

From this 500 sqm pasture landscape with double use : olive-trees growth !

And/or holm oaks, with their acorns to flour alternatively to wheat bread  or for noddles production !
Vertical farming is not a must somewhere !
But low cost " electro-culture" is for outdoor  landscapes more interestant :

up to 100% more yield per work/land area !

Beginnig with seed " programming"  ::) ;) :)   

"Water on  demand" - sensor ! Plants call for it,not the farmer over-waters the field !



1000 sqm per capita x 5 ( virgin/ extensiv  nature ) = 5000 sqm per habitant = 2 per ha = 200 habitants/sqkm

Anymore " war for food" ,over the time up to 80% price maximun decrease !
Peak prices cut !

Up to 100 times less land use for the same photovoltaic or windforce conversion and consumer-near exploring :

Portugal,Algarve,Alcoutim,Martim Longo : 1750 KWh solar radiation per annum

https://jornaldoalgarve.pt/alcoutim-vai-ter-a-maior-central-solar-do-pais/
800 ha land for 0,4 Euros per sqm means 1,5 % from 220 Mio Euros total investment costs .
4 ha per MW solar panel installation              or 40 sqm per KW

Assuming 225 000 000 KWh or 225 GWh electricity conversion per annum this means by international solar parcs 2 Euro-Cents/KWh market selling price 4,5 Mio Euros per annum R.O.I. /200 Mio. investment = ONLY 2,25 % cash flow by "free market " conditioning !
Only for investment amortization ( 30 years) and 2,5% ( green tax ) capital tax we need 4,7 % annual net cash flow =4,4 Euro-Cents per KWh warranted ( by someone ) !

but here the first " max. " price barrier : b2b energy price,included distribution  :        https://www.ispex.de/
                                                                                                                        actually 5,5 US $cents or 4,74  Euro-Cents/KWh  average

+ second " max. " barrier     https://www.eex.com/de/  the energy market of "surplus electricity"

                            Question : how much fractional-Cent per KWh for  the "solar parc " service/maintenance costs and salaries for up to " local 600 jobs" ??

Wind force conversion : https://www.vernunftkraft.de/dreisatz/
conventional : 3,3 ha / 1 MWp

but : 1 MWp means by average 16 - 20 % "Voll-Last " 170-200 KW average

Mit den angegebenen Werten für die Volllaststundenzahl liegt die durchschnittliche Leistung einer WKA demzufolge zwischen 16 und 20 % der Nennleistung. Eine WKA mit einer Nennleistung von 3 MW = 3000 kW hat also eine durchschnittliche Leistung zwischen 500 und 600 kW.Die durchschnittliche Leistung einer WKA (Formelzeichen PWKA) liegt demnach bei

Da eine WKA praktisch nie bei Nennleistung betrieben werden kann, weil der Wind selten mit der entsprechenden Intensität weht, liegt die durchschnittliche (tatsächliche) Leistung immer ganz wesentlich darunter. Diese Tatsache wird durch die sogenannte Volllaststundenzahl (Formelzeichen TV) erfasst. Typische Werte liegen auf dem Festland um 1800h , andere Autoren stellen zwar größere Werte von bis zu 2500 h in Aussicht- die durchschnittliche Volllaststundenzahl lag für alle existierenden WKA in Deutschland im Jahr 2012 allerdings nur bei 1500h. Das Jahr hat 8760 h. Die durchschnittliche Leistung einer WKA (Formelzeichen PWKA) liegt demnach bei

Here as solution : artificial wind chamber ( similar " Compressed Air Engines " )

When we need by conventional wind generator installation 3,3 ha /MWp ~ 33 sqm/KWp and get in average 1500 hours capacity power from 8766 hours the yearand as "wind chamber" we need 60 sqm /100 KWp or 0,6 sqm/KWp and by 8766( x 0,9 )  permanent full capacity work potential


the result per annum a. conventional "on-shore" 1500 KWh/33 sqm =        45,5 KWh/sqm 

                                      b. wind chamber (8766 KWh  x 0,9)/0,6 sqm =      13 149 KWh/sqm

wind chamber numbers from  archive.org / www.airpower.co.il, israelitan inventor Israel Hirshberg

Melvin Prueitt,Los Alamos scientist and inventor (R.I.P.) " dreamed" about 1 Km high cooling wind towers ,we do not need to think in such hights,even not as translucent,glassy,wall towers !


Btw : Prueitt invented " airpower"- similar concept : he called it "Air-Watt"

Better yet, it can be readily made into a foam. “With most metals that’s difficult, because the bubbles want to rise to the surface of the molten metal,” says Johnson. The fact that amorphous metal is thick and like plastic when molten permits the formation of a foam panel that is 99 percent air but roughly 100 times stronger than polystyrene. A sandwich made of two thin sheets of amorphous metal flanking amorphous foam would be strong, light, insulating, fireproof, bug-proof, rustproof, sound dampening, and difficult to penetrate with bombs. Such panels could form buildings, ship hulls, airplanes, and car bodies.
“Glassy metals will be a cut above both metals and plastics,” says Kang, looking up from a plasma arc melter in which he forges new formulations. Asked if his aim is to replace both—which covers a lot of territory—he smiles. “That’s what we’re shooting for,” he says.
But metallic glass has one huge problem—it’s expensive. The first commercialized injection-moldable form costs about $15 a pound to make versus roughly $1 a pound for aluminum and 25 cents a pound for steel. Johnson, Kang, and other researchers are working on variants with cheaper constituents. “I think we can make a viable amorphous steel product. I would call that a very likely development,” says Johnson. Eventually, he says, it could cost the same 25 cents a pound as ordinary steel. “That will change everything,” he says.
