Another week has passed and the storm has come and gone; however it came at a time that prevented the BELARE members we were meant to welcome from landing.
The sun came back in time for Kristof's birthday. Kristof's sense of humour is so rock solid that not even the storm can dent it. People smile in expectation when he arrives, because they are sure he will raise the mood. The cooks expressed our thanks for his gift by making him a dinner to be remembered. A sauce of morilles and asparagus of unbeatable delectation was not surpassed even by the moist chocolate birthday cakes (all three of them) complete with birthday candles in twirls and little plastic holders.
We have been forging ahead with the fine-tuning of the Active Systems. Most days Johan or Sven will stick their head around the door into the office to tell me some good news, some breakthrough or some difficulty they are having.
Sometimes Thomas comes to tell me how he's doing with the water production from the thermal solar panels, and we watch excitedly as the number of litres begins to creep up, while Jean frets about the temperature of the panels, which he follows in intimate detail on his computer screen. It's a tough job trying to get everything running up to optimal levels to be able to do the tests when the systems can't run optimally until they are fully functioning, which means that you have to balance supply and the demand.
Dominique is preparing to do the first bioreactor tests with Bernard using just water to check for leaks in the system. We were allowed showers two days in a row as the system was tested to see how it would manage. Michael is in a cocky mood as he finds a pump that had been installed back to front in the ventilation system. There are still some ventilation issues in the technical core, but we are slowly ironing these out.
For a while now it has also been solid gains with the grid, as Sven has relentlessly pursued the Holy Grail of full synchronized operation with the generators. Last night, at 10:10 pm with the last parameters tweaked, we were suddenly running entirely on renewable energy for the first time. We have abundant solar and wind energy. The batteries are full, and finally the gensets are talking to the PLC. It is a moment of quiet triumph. We hold our collective breath to see how it will perform, and in the morning everything is still running. The power is stabilizing. Wim is smiling contentedly.
The mood is upbeat. The fuel platform was completed in just under four days, all sixty meters of steel sitting on the ridge. It was exhausting and the wind often less than balmy.
On Tuesday, Sanne and Alain T. took Steve Roberts and Elie Verleyn to Brattnipene. The site is everything they had hoped for apparently, and they are making good progress. Alain came back alone and now he and René take the biologists, Zorigto and Josef, to check out promising sites for extreme life forms. You need very particular conditions to catch sight of the earliest and most archaic types of life. You can't go where anything else like snow petrels live because their presence contaminates the site with organic material that covers up the traces of the cyanobacteria.
The days tick by, and Alain, François and Koen begin working on the satellite platform. Yes, another platform to build. Then it will be the new windmills. The work never stops around here.

Princess Elisabeth Energy production: 22 m2 thermal solar panels (12%) - 380 m2 photovoltaic solar panels (40%) - 9 wind turbines (48%)
http://www.antarcticstation.org/station/zero_emission/
The First "Zero Emission" Station
Unique in its design and construction, the Princess Elisabeth Station is the only polar research facility to have been conceived and built to operate entirely on renewable energies. Wind power is thus used solely to supply the station with electricity, while solar power provides both electricity (photovoltaic solar panels) and hot water (thermal solar panels), allowing the station to function with zero carbon emission.
Energy production: 22 m2 thermal solar panels (12%) - 380 m2 photovoltaic solar panels (40%) - 9 wind turbines (48%)
Such an environmentally-friendly station is the fruit of the designers’ meticulous study of how occupants would live in and around the station. The main structure of the station consists in concentric layers surrounding a central technical core, which holds the water treatment units, ventilation and control systems, and batteries for energy storage. Around this core are three concentric layers: the station’s active systems (kitchen and laundry rooms), the external areas (living and sleeping rooms), and the heavily insulated, multi-layered outer walls of the station.
Zero Emission Concept
The station, designed according to a “zero emission” concept, integrates passive building design with renewable energy sources run through a smart grid with a programmable logic circuit (PLC) to manage the use of energy in the station. Any excess energy is stored in batteries located inside the central core of the station, a configuration that ensures optimal resource consumption.
Whenever someone wants to plug something in, he or she must first push a button to ask the PLC whether there is energy available. Different modes feature different priority levels for energy use in the station, with essential functions such as ventilation and the bioreactor receiving high priority, bathroom and kitchen appliances receiving medium priority and outlets used to connect additional non-essential items receiving low priority. If there is energy available, the PLC diverts requested energy to the outlet.
Minimizing its impact on the environment won’t end after the Princess Elisabeth Station reaches the end of its functional life, either. Constructed from wood and a stainless steel structure, the station was designed so it could be easily disassembled and shipped out of Antarctica, where a number of its wooden and steel components can be recycled and re-used.
Renewable Energy
The station is designed to be powered by a combination of two renewable and carbon-neutral technologies for producing electricity: wind and solar power. While wind power will be used to supply the station with electricity all year long, solar power will provide both electricity (photovoltaic panels) and hot water (solar thermal panels) during the austral summer.
Water Treatment
In line with the requirements of the Antarctic Treaty to minimise environmental impact, the Princess Elisabeth station will be equipped with a specially designed water treatment unit. Inspired by technology developed for the space sector, the two bioreactors and two filtration units will allow the station to treat 100% of its grey and black waters. Most of the recycled water, although fit for human consumption, will be reused for other functions.
Passive Building
The station's skin, insulation, shape, orientation and window disposition allow a comfortable ambient temperature to be maintained inside the building with little energy input. Sophisticated ventilation and air circulation systems are an integral part of temperature management. The Princess Elisabeth station was conceived to take full advantage of currently available passive building techniques.
Smart Systems
All station systems are integrated and piloted by an intelligent central unit. This configuration will ensure that working and living conditions inside the station are optimised with minimal resource consumption. This centralised control of interdependent systems also allows for remote monitoring during the winter.

Hiinas ehitatud ja Eestis täiustatud väikeauto Zev Smiley'le

Eestis täiustatud elektriauto sobib vaid linnasõiduks
22.09.2009 19:18
Eilsel Eesti esimese avaliku elektriautode laadimiskoha avamisel Vabaduse väljaku maa-aluses parklas andis Tallinna linnapea Edgar Savisaar tasuta parkimise kaardid kahele kohal olnud sõidukile - Hiinas ehitatud ja Eestis täiustatud väikeautole Zev Smiley'le ning Soomes Elcati tehases elektrisüdame saanud Subaru kaubikule.
Esimene neist kuulub Zev Motors OÜ osanikule ja tegevjuhile Teet Randmale, teine sama firma teisele osanikule Meelis Merilole. Aasta jooksul saavad tasuta parkida ka teised Eestis registreeritud elektriautode omanikud.
Teet Randma rääkis, et Smiley oli Hiinas üks esimesi elektriautosid ning kuna Eesti kliimale ei sobinud see kuigi hästi, tuli seda Eestis kõvasti täiustada. Nüüd peab masin vajadusel vastu ka talvistes oludes, kuigi külmema ilmaga kannatab läbisõit.
«Kui tahta teda teha talveautoks, siis saaks väga ilusti hakkama,» märkis Randma, lisades, et praegu ei ole autol aku soojustatud ning talvine läbisõit on vaid 35 km.
Tavaoludes saab Zev Smiley'ga ühe laadimisega sõita 85 kilomeetrit, et aga auto tippkiiruseks on vaid 55 km/h, jääb see pelgalt linnasõidukiks. Auto aku täislaadimine võtab aega 8 tundi.
Soomes Elcati tehases Subaru kere peale ehitatud elektrimootoriga kaubiku maksimaalseks läbisõiduks on Randma sõnul samuti umbes 80 km, maanteekiirusel aga umbes kaks korda vähem.
Kaubikul on erinevalt Smiley'st Randma sõnul akud juba soojustatud ning läbisõit välistemperatuurist ei sõltu. «Seda saaks suhteliselt lihtsalt teha ka Smiley'ile või ükskõik mis teisele elektriautole, aga momendil seda lihtsalt pole tehtud,» märkis Randma.
Salongi saab Smiley'l aga praegugi gaasikütte abil soojaks, Subaru seevastu kasutab reisijate soojendamiseks bensiini. Salongi soojendamine elektriga ei ole Randma selgitusel otstarbekas. Gaasisoojendi soojendavat aga salongi märksa kiiremini kui bensiiniautol.
Randma selgitusel on aku mahtuvuse vähenemine madalamal temperatuuril pliiaku omapäraks, kuid tänapäeval on aktuaalsem liitiumaku, millel seda probleemi ei ole. «Lihtsalt need on vana generatsiooni elektriautod, aga viimase poole aasta jooksul on liitiumi hinnad kukkunud nii palju, et nüüd on juba mõistlik osta liitiumakudega auto,» rääkis Randma.
Et ainus Eestis registreeritud Zev Motorsi auto kuulub firma tegevjuhile endale, polegi nad ühtegi elektriautot veel müünud. Küll on aga Zev Motors OÜ müünud elektrirollereid, elektri-ATVsid ja elektrijalgrattaid.
Päris märkamatuks pole siiski jäänud ka sõiduautod - firmal on kaks klienti, kellele on toodud 4-kohalised uue generatsiooni Smiley'd, kuid ARKis on nende registreerimisega probleeme.
Ühe kliendiga tehti Randma sõnul selline kokkulepe, et talle ehitatakse Volkswagen Golfist Zev Smiley komponente kasutades elektriauto, teine klient on aga otsustanud ARKis lõpuni võidelda.
Zev Motors OÜ'l on ka üks päris Eestis tehtud auto, Võidusõidutehnika ASi Tartu tehases Estfieldi baasil valminud Zev Seven. Seveni suuremahulisest tootmisest on Randma sõnul veel vara rääkida, kuid kuna Tartus suudetakse teha 30 autot aastas, tuleks suurema nõudluse korral tootmine välja viia.

Väiksem energiakulu, ohutum liiklus, parem juhitavus?
anyone who has ever driven a car dreads getting a flat tire, but what if your tires could never go flat?
in recent years a number of companies and inventors have been working on creating airless tires that
would be impossible to puncture. the most well known design in this field is the michelin tweel,
a combination wheel and tire. the design was one of the first to emerge, bringing the idea of non-pneumatic
tires to the public's attention. but michelin has been slow to roll out the technology beyond the test phase.
in light of this, a company called resilient technologies has also been working on an airless tire.
the company recently announced that prototypes of their honeycomb-like tires will ship in 2011 for use
in the US military. this will no doubt help the airless tire field, as will other startup companies working
on the task like britek. you can see their design below and a video explaining more. with this much
competition in the field, we may see non-pneumatic tires on consumer vehicles in the near future.

1000 km
Eile 19:48 sai siis Tipi ringil täis esimene 1000 km elektri jõul. Kõik see siis linnas ja kuni 15 km juppide kaupa. Ei läinudki palju aega, umbes täpselt 4 kuud.
Ilmad on nüüd ka juba soojemad, esimene talv ilma salongisoojenduseta üle elatud. Ega see liiga mugav olnud, aga midagi katastroofilist samuti mitte. Ilmselt oli suureks abiks see, et öösiti on auto ikkagi garaazhis. Mõni hommik oli ikka hea küll, kui ei pidand autot kratsima.
Liitiumakude testimisega jõudsin nüüd niikaugele, et sai muretsetud endale järjekordne elektrijõuline sõiduk. Sedapuhku siis ilus punane nimetu roller www.zev.ee poiste käest. Jutu järgi võimsust u. 1KW, kiirust piisavalt (50 km/t).
Pliiakudega jõudsin läbisõiduks testida null kraadi juures - u. 20 km.
Oma hiinamaise päritoluga 48V 10Ah LiFePO paki läbisõitu ei ole õnnestunud kahjuks lõpuni ära testida, sest kontroller veel lõpuni korralikult ühendamata. Aga roller liikus küll, kuigi pingelang oli oodatust suurem. Samuti soojenesid akud päris tublisti.
Kuna mul ajanappuse tõttu pole õnnestunud piisavalt mõõteinstrumente installida, siis ei oska veel öelda ka täpsemaid numbreid. Küll sai aga juba selgeks, et nendest konkreetsetest elementidest ei tahaks ma oma autole küll akupakki teha. Tuleb teste ja otsinguid jätkata, kui jälle võimalusi on.
