The new device is a cross between today's transistors and the vacuum tubes of yesteryear. It's small and easily manufactured, but also fast and radiation-proof. Meyyappan, who co-developed the "nano vacuum tube," says it is created by etching a tiny cavity in phosphorous-doped silicon.

They claim switching up to 0.46 terahertz.

Because there's nothing like a single-ended triode to add some warmth to your flip-flop?  :P

Yes I've always preferred the sound of valve flip flops to those new digital ones.

I still like the mechanical calculator my grandpa found at a tag sale...

this one, or maybe a slightly different model

Can you fix a frozen computer with WD-40?  No?  I thought not.    :)

Great stuff. My tag line for this sort of thing (referring to the use of computers in 4x4 vehicles in the outback) is

"Can you fix the computer with a sapling and some fencing wire?"

I suppose that depends upon what's wrong with it.

As for retro computing, if piles of money showed up, I'd acquire a Curta calculator.
