Came across this yesterday. It cuts a core instead of shaving its way thru the ice. Seems it would take a lot less energy than augers. Wonder why nobody refined/updated the concept.
They had power auger versions of that too...<°)))>{
Basically like a woodworkers hole saw. Cuts a ring and core is captured in the sheet metal.From my use of hole saws, they developed a lot of friction and get very hot. That would be a non issue or maybe even a plus for ice coring. Now that I think of it that’s how they sample glacial ice. They used fluids like kerosene with core drills to drill into Lake Vostok, over 13,000 ft. of ice. https://en.m.wikipedia.org/wiki/Lake_Vostok. Talk about safe ice!
Now u know ya gotta be the first to fish that virgin lake
