Amerikaanse diplomaat van Nigerië - aardskip.com - USA Diplomate from Nigeria.

It seems that Orania and the Aardskip help each other to become more and more famous. We had a visitor from Nigeria, a USA diplomate in Nigeria. See photo of Edwards Waters and his family.

On the drought question of the previous blog. Our water tanks are currently completely full and we seem to be back to the normal rain cycle. If anybody can donate the Aardskip a 5kl water tank it will be highly appreciated, because last night we had 18mm of rain and we could not capture it.
Dit blyk dat Orania en die Aardskip mekaar help om meer en meer bekend te word. Ons het 'n besoeker uit Nigerië ontvang, 'n VSA diplomaat in Nigerië. Sien foto van Edwards Waters en sy gesin.

Wat betref die droogte vraag van vorige keer. Ons watertenks is tans heeltemal vol en ons blyk terug te wees op ons normale reën siklus. As iemand vir die Aardskip 'n 5kl watertenk kan skenk sal dit hoog op prys gestel word, want gisteraand het ons 18mm reën gekry wat ons nie kon opvang nie.

Droogte gebreek of nie - aardskip.com - Drought, yes or no?

We had all hopes that 2016 will not be a drought stricken year. Unfortunately February does not give us any good indications. We had thus far only 3.4mm rain, where as in previous years it rained just about every week and up to 45mm in the month.

Furthermore it is extremely hot, we keep on hitting the 40 degree Celcius mark. The earthship can compensate about 12 degrees. This makes the rooms bearable, however the living area is to open get all the advantage. We will start to implement more climate control measures in the future.

The other interesting aspect is that the sun is now starting to move into the earthship, so it is time to saw some seeds. We can not wait to have some veggies in the house again. See the line on the windowsill in the photo.
Ons het gehoop dat 2016 nie 'n droogtegeteisterde jaar sal wees. Ongelukkig voorspel Februarie niks goed nie. Ons het tot dusver slegs 3.4mm reën gekry, waar dit die vorige jare omtrent elke week gereën het, en tot en met 45mm vir die maand.

Verder is dit baie warm en Orania raak die 40 graad Celsius merk gereeld, onder ‘n koelte boom. Gelukkig kompenseer die aardskip die temperatuur met ongeveer 12 grade. Die kamers is draaglik, egter is die leefarea te oop om die hele voordeel te kry. Ons sal begin om meer klimaat beheermaatreëls in die toekoms te implementeer.

Die ander interessante aspek is dat die son nou begin om in die aardskip in te skyn, so dit is tyd om 'n paar sade te saai. Ons kan nie wag om weer groente in die huis te hê nie. Sien streep wat die son maak op die vensterbank foto.

Voorspoedig outargiese jaar - aardskip . com - Prosperous off-grid year - Goto the weblog for more info.

Laas jaar het ontsettend droog en warm geëindig, maar gelukkig het ons nou al redelik reën ontvang. Hier is die reënval so ver gemeet by aardskip, dit word om 6:00 elke ogend gemeet:
12 Jan - 16,0mm
14 Jan - 2,2mm
17 Jan - 2,0mm
19 Jan - 0,8mm
20 Jan 12,5mm
22 Jan – 0,8mm

Die watertenks is so 65% vol. Dit gee ons ongeveer 20kl water wat ons so 4 maande moet hou.

Hier is twee fotos van interessante vrugte wat ons in die toekoms kan verwag. Die eerste foto is van ons pekanneut boom buite wat ons swartwater gebruik. Die ander foto is een van ons druiweranke binne in die huis wat ons grys water gebruik.

-o0o---------------------

Last year ended extremely dry and hot, but fortunately we already received a reasonable amount of rain. Here are the rainfall so far measured at the earthship, it is measured every moring at six o'clock:
12 Jan - 16,0 mm
14 Jan - 2,2mm
17 Jan - 2,0mm
19 Jan - 0,8mm
20 Jan 12,5mm
22 Jan – 0,8mm

The tanks are about 65% full. This gives us more or less 20 kl of water and should last as about four months.

Here are two pictures of interesting fruit we can expect in the future. The first photo is of our pecan tree outside using our black water. The other picture is one of our inside grape vine which uses our gray water.

Actual Solar Power verus Model - aardskip.com - Werklike sonkrag versus Model.

In the graph you see the actual and theoretical solar power in kWh per kW installed PV pannels average per day every month.

In die grafieke sien u die werklike en  teoretiese sonkrag in kWh per kW geïnstalleer panele gemiddeld per dag elke maand.


The following points can be derived from the chart:
+ These model values includes a 40% loss.
+ Both values is kWh per kW installed PV pannel.
+ The panels are installed at a angle of 40 degrees.
+ The discrepancies (in. March, October) could be from weather conditions.

-o0o-----------------------------------------

Die volgende punte kan afgelei word uit die grafiek:
+ Hierdie model waardes sluit 'n verlies 40%.
+ Beide waardes is kWh per kW geïnstalleer sonpaneel.
+ Die panele is geïnstalleer op 'n hoek van 40 grade.
+ Die teenstrydighede (in. Maart Oktober) kan wees van weerstoestande.

Effect of the PV direction on the Solar Power - aardskip.com - Effek van die sonpaneel se rigting op krag lewering

In the graphs you see the theoretical effect of the solar panel's direction on the solar power in kWh per kW in installed per day.

In die grafieke sien u die teoretiese effek van die sonpaneel se rigting op die sonkrag in kWh per kW geinstalleer per dag.


The following points can be derived from the chart:
  • [30 NS] - solar panel's angle is 30 degrees in the north-south direction on the horizon at a latitude -29.83.
  • [30 W] - solar panel's angle is 30 degrees in the western direction from the horizon.
  • [Beide] - Half of the solar panels are tilted NS and the other half is tilted in the Western direction at 30 degrees.
  • The panels tilted at a 30 degrees in the North-South direction offer the best results, Winter and Summer.
  • The panels tilted at a 30 degrees in the western direction give the worst results, an average loss of 24% per year.
  • Even a combination of panels deliver worse results, an average loss of 12% per year.
Note: Due to other losses will the practical results be about 85% of the theoretical results. Furthermore, we can assume that heat in the summer will reduce the power.

The graphs are calculated with models developed by Aardskip Projects. Need similar graphs for your latitude contact us.

-o0o-----------------------------------------

Die volgende punte kan van die grafiek afgelei word:
  • 30 NS - Sonpaneel se hoek is 30 grade in die Noord-Suid rigting van af die horison by ‘n breedtegraad -29.83.
  • 30 W - Sonpaneel se hoek is 30 grade in die Westelike rigting van af die horison by ‘n breedtegraad -29.83.
  • Beide – Helfte van die sonpanele is N-S gekantel en die ander helfte is Wes gekantel ten 30 grade.
  • Die panele wat 30 grade in die Noord-Suid rigting gekantel is lewer die beste opbrengs, Winter en Somer.
  • Die panele wat 30 grade in die Westelike rigting gekantel is lewer die swakste opbrengs, ‘n gemiddelde ’n 24% verlies per jaar.
  • Selfs ‘n kombinasie van die panele lewer nie goeie resultate nie’n gemiddelde 12% verlies per jaar.

Nota: As gevolg van verliese sal die lewering ongeveer 85% wees van die teoretiese syfers. Verder moet ‘n mense aanvaar dat hitte in die Somer gaan die krag lewering verlaag.

Die grafieke is bereken met modele ontwikkel deur Aardskip Projekte. Benodig u soortgelyk grafieke vir u breedtegraad kontak ons gerus.

Die volgende punte kan van die grafiek afgelei word:

  • NS - Sonpaneel se hoek in die Noord-Suid rigting van af die horison by ‘n breedtegraad -29.83.
  • Elke kleur is ‘n ander hoek, blou - 20, oranje - 30, geel - 40, groen - 50 en rooi-bruin -  60 grade.
  • Die laagste hoek, 20 grade, lewer die meeste krag in die Somer maande.
  • Die hoogste hoek, 60 grade, lewer die meeste in die Winter.
  • 50 grade lewer die minste afwyking in die jaar en piek in die Lente en Herfs.
  • Die beste jaarlikse gemiddeld krag lewering is by ‘n hoek van 30 grade.

Nota: As gevolg van verliese sal die lewering ongeveer 85% wees van die teoretiese syfers. Verder moet ‘n mense aanvaar dat hitte in die Somer gaan die krag lewering verlaag.

The following points can be derived from the chart:

  • NS - PV's angle in the north-south direction from the horizon at a latitude of -29.83.
  • Each color is a different angle, blue – 20, orange - 30, yellow – 40, green – 50 and red-brown - 60 degrees.
  • The lowest angle, 20 degrees, provide the best results in the Summer months.
  • The highest angle, 60 degrees, provide the best in the Winter.
  • 50 degrees produces the least variance throughout the year and peaks in the Spring and Autumn.
  • The best annual average power is at an angle of 30 degrees.
Note: Due to losses you can expect and 85% of the theoretical figures. Furthermore, we must assume that the temperature in Summer will lower the  power output.

These graphs is generated with models developed by Aardskip Projects. Do you need similar calculations for you latitude, please contact us.

Sonkrag en verbruik- aardskip-com - Solar power and usage - Goto the weblog for more info.


The graphs shows the solar energy received in the earthship in BLUE and in RED is our consumption in kWh.

The following points can be derived from the chart:
1. The solar power is generally more than the consumption.
2. In the case where the solar power is less than consumption, the system will compensate the next day.
3. It happens, because the system is trying to keep the batteries full.
4. Winter is the solar slightly less than in the Summer.
5. The maximum kWh is attained in the Fall and Spring.
6. Makisimum in one day was 11,7kWh for a 2kW PV and 254Ah batteries.
7. Minimum was 0,7kWh and the average was 6,77kWh.
8. The total delivered was 6,1MWh (Mega Watt hours) over the period of 2. 5 years.

What was you electricity bill the last 2.5 years?

-o0o-----------------------------------------

In die grafieke sien u die sonkrag wat aardskip ontvang het in BLOU en ons verbruik in ROOI in kWh.

Die volgende punte kan van die grafiek afgelei word:
1. Die sonkrag is meestal meer as die verbruik.
2. In die geval waar die sonkrag minder as die verbruik sal die stelsel kompenseer die volgende dae.
3. Dit gebeur om dat die stelsel probeer altyd die batterye vol hou.
4. Winter is die sonkrag effens minder as in die somer.
5. Die maksimum word behaal in die Herfs en Lente.
6. Maksimum in een dag was 11,7kWh vir ‘n 2kW stelsel.
7. Minimum was 0,7kWh en gemiddelde was 6,77kWh.
8. Die totaal gelewer is 6,1MWh (Mega Watt uur) oor tydperk van 2, 5 jaar.

Wat was u kragrekening die laaste 2,5 jaar?

Reënval en tenks watervlak - aardskip.com - rainfall and tanks water level.


In die grafiek sien u ons watervlak in ons 30kl tenks. 'n Vlak van 2000mm is 100% vol.

Die volgende punte kan van die grafiek afgelei word:
1.   U sal merk dat in 2013 het ons die tenks 3 keer met rivierwater aangevul, geen reënval maar tog word die tenks voller.
2.  In 2014 en 2015 was dit nie nodig nie.
3.  U sal sien dat die tenks drie keer in 2014 en eenkeer in 2015 oorgeloop het.
4.  Laastens van die grafiek kan ons ook aflei dat dit waarskynlik binne kort gaan begin reën.  

-o0o-----------------------------------------

In the chart you will see our water level in our 30kl tanks. A level of 2000mm 100% full.

The following points can be derived from the chart:
1.   You will note that in 2013 we filled the tanks three times with river water, not rainfall but the tanks were fuller.
2.   In 2014 and 2015 it was not necessary.
3.   You will see the tanks were three times in 2014 and once overfull in 2015.
4.   Finally, from the chart we can conclude that it probably will rain soon.

Realiteitsmuseum en EJM en Snappy - aardskip.com - Reality museum, EJM and Snappy

The earthship is once again open as an open air museum or if you will a reality show. Thanks to my company EJM, http://www.ejm.co.za/. We are again able do do earthship viewings for a small donations, guideline is R25 per person and R100 for groups. More or less is also welcome. People living in Orania can view the earthship for free.

A couple of months ago I mention that my Snappy induction plate packed up and in the process my Nelson Adams inverter also packed up. Both got fixed, but the Snappy and the inverter refuse to work together.

So all things considered I decided to move away from the fancy induction plate technology to more conventional technology that is not so fragile and with so much electronics. Just to expensive to get fixed all the time. So I bought an Ceramic two plate hob and a normal kettle. Interesting I still
have enough power.

The fact is a normal kettle is much faster than the Snappy and the Ceramic plates as seen in the photo does not waste much more energy than the much more fragile induction plate.

-o0o-----------------------------------------

Die aardskip is weer oop as 'n opelug museum of as jy wil 'n realiteitsprogram. Met dank aan my maatskappy EJM, http://www.ejm.co.za/. Ons is weer in staat om aardskip-besoeke aan te bied in ruil vir klein donasies, riglyn is R25 per persoon en R100 vir groepe. Minder of meer is ook welkom. Vir Oraniërs is dit gratis.

'n Paar maande gelede het ek noem dat my Snappy induksie plaat opgepak het en in die proses my Nelson Adams omsetter ook opgepak. Beide is herstel, maar die Snappy en die omsetter weier om saam te werk.

So alles in ag genome het ek besluit om weg te beweeg van die ingewikkelde induksie plaat tegnologie na 'n meer konvensionele tegnologie wat is nie so broos en met soveel elektronika werk nie. Dus het ek vir ons 'n Keramiek twee plaat stoof en 'n normale ketel gekoop. Interessant genoeg ons het nog steeds genoeg krag.

Die feit is 'n normale ketel is baie vinniger as die Snappy en die Keramiek plate soos gesien in die foto nie gebruik nie veel meer krag as die veel broser induksie plaat nie.
