I have a new preprint out, which is about choosing the right solar regulator for solar-powered instrumentation.

doi.orgSolar power systems for polar instrumentation: why night consumption mattersAbstract. Autonomous instruments, powered using solar panels and batteries, are a vital tool for long-term scientific observation of the polar regions. However, winter conditions, with low temperatures and prolonged lack of sunlight, make power system design for these regions uniquely challenging. Minimising winter power consumption is vital to successful operation, but power consumption data supplied by equipment manufacturers can be confusing or misleading. We measured the night consumption (power consumption in the absence of sunlight) of 16 commercially available solar regulators and compared the results to the manufacturers' reported values. We developed a simple model to predict the maximum depth of discharge of a battery bank, for given values of regulator and instrument power consumption, solar panel size, location, and battery capacity. We use this model to suggest the minimum battery capacity required to continuously power a typical scientific installation in a polar environment, consisting of a single data logger (12 mW power consumption) powered by a 12 V battery bank and 20 W solar panel, for eight different models of solar regulator. Most of the tested solar regulators consumed power at or below the manufacturer's reported values, although two significantly exceeded them. For our modelled scenario, our results suggest that the mass of the battery required may be reduced by a factor of 26x by exchanging a solar regulator with high night consumption for a more efficient model. These results demonstrate that a good choice of solar regulator can significantly increase the chances of successful year-round data collection from a polar environment, eases deployment and reduces costs.

Gestern hatte ich ein Spontandate a. d. Dagmar AAEN des Polarforschers Arved Fuchs. Kurzer Aust. m. Arved Fuchs u Filmemacher.

Z. Zt liegt d. Boot auf dänischer Werft a. d. Flensburger Förde. Beim Abschied ließ ich es mir nicht nehmen, noch dieses Bild zu machen.

SpaceX blasts off first human spaceflight, taking 4 astronauts on Earth’s polar orbit

Crew members will attempt to exit the spacecraft without medical assistance after re-entry, helping researchers study astronauts’ post-spaceflight capabilities. Unlike previous missions, Earth's polar regions have remained unseen by astronauts, including those aboard the ISS and Apollo missions.

#Winter #seaice in the #Arctic just hit a record low
After months of #polar darkness, the extent of sea #ice blanketing the Arctic this winter "fell to the lowest level on record, researchers announced this week... the smallest maximum extent in the 47-year satellite record, according to the National Snow and Ice Data Center.

The MAN #Polar Express, a battery-electric eTGX truck, completed a 3,400-kilometre journey from the #Arctic Circle to #Munich, using only public charging infrastructure. With an average consumption of 117 kWh per 100 km, it demonstrated a range of 400-500 km, even in winter. The tour saved up to 2.7 tonnes of CO2 compared to a diesel truck. The truck's journey, accompanied by influencers, highlighted the ease of charging using the MAN Charge&Go card and the competitiveness of electric trucks in long-distance transport. At the Allianz Arena, FC Bayern legend Giovane Élber received the truck, marking the success of MAN’s demonstration of electric transport capabilities. The MAN eTGX showed cost-effectiveness with charging costs comparable to diesel, and its modular battery options offer flexibility for various #transport needs. The tour’s social media coverage further showcased the potential for electric trucks in future long-distance operations.
