Thats a methane capture devise on the cow, seem silly as you would have to drill a hole in your cow, and empty the bladder on its back when it is full.
And then you still have to figure out what to do with the methane, just burning it i don't think work but maybe make it into something less aggressive.
There is 1 night in the 2 week forecast with -1 deg C or so, and so far i think the max have been -7 for a single night, so it will have to be really still water to freeze over, and with a very thin layer of ice.
But the average so far have been 1 night with a little frost every 2 weeks, so far from the weather of my youth where you could go skating on frozen lakes for weeks on end, and the really hard winters you could drive your car on the ice on Aarhus bay, and that's saltwater.
I also think the 2-3 icebreakers we had are sold off or scrapped / belay that they are laid up and awaiting a buyer as of August last year.
Both are as old as myself, so mid 60ties when they was launched.
Global warming indeed.
Last so called icewinters here was 2009-10 and 2010-11, but then the icebreakers did not have to enter service as ships are now so powerful they don't need the assistance with the levels of ice we see here now.
The winters 1941- 42 and 1947- 48 was so bad all small islands here you could walk or ride a horse and cart to the mainland to get supplies.
Pushing/pulling a boat with the supplies was also common back then for remote islanders.
