New Heat Pump Will Last 10,000 Years

formaggio writes "Most heat pumps maintain an average useful life of 10-20 years, but researchers at the University of Stavanger in Norway (USN) and the University of Oslo believe that they have developed a new heat pump that will last up to 10,000 years."

Poor estimation

This is like the bridges built in the '60s that were supposed to last over a hundred years, but need to be replaced now. By the time they have to be replaced, the companies manufacturing them will simply no longer exist to sue and will have moved on to Carbon Fiber (the next 100+ year technology that won't last nearly 100 years).

Part of that problem, iirc, was the US Army going with a different, cheaper, ammo then intended during design.

Most of it was because it was designed only for firing and carrying specs and tested only in clean conditions.

Jump into a couple of foxholes and you're disassembling the fucking thing to get the sand out from between the bolt and the receiver. Whereas you could shake an AK-47 clean in a muddy puddle and come up firing.

If the ammo added problems, that's the ammo's problem. The M-16 was a weapon characterized by an occasional failure to fail.
