To make no excessive claims, I have to admit I burnt a fair bit of wood during the night. In the morning however, around 9 o'clock, the solar fence (nominal power 2400 W) was giving 600 W and steaming vigorously. By 10 o'clock, it had thawed and gave 940 W. Later, other panel arrays took over and wattage decreased. The energy was used to run a heat pump.
P.S. Knowing that server resources aren't infinite, I hosted the image externally, I hope that hosting on "postimages.org" works smoothly.
Estonia, just south of Finland. It was not particularly cold, only -5 C during the night in places where the sky was starry. By the time of taking the photo, there was a considerable difference between air temperature and surface temperatures - thus the steaming. :)
We got global warming here - yesterday it was +5 in Udmurtia
Wow, I would expect Udmurtia to have a continental winter at this time, but nope. :)
We have had a very mild autumn also, this is the first time ground starts to freeze a little, on the top. Tiny field roads that were unpassable by car will be passable (if one is careful) after a day or two. For me, this means: I can bring firewood with a car, not with a garden cart. :D
Snow has not bothered to appear so far. Some time every autumn, wind starts blowing from the north and the Gulf of Finland subsequently tries to evaporate and fall into Estonia. Hasn't happened yet. Surprises us every time. :P
