The Quest For the Ultimate Vacuum Tube (ieee.org)
An anonymous reader writes: IEEE Spectrum reports on progress in the development of vacuum tube technology, which remains surprisingly relevant in 2015. "In the six decades since vacuum tubes lost out to solid-state devices in computers, receivers, and power supplies, vacuum technology has continued to evolve and branch out into new terrain, sustaining a small but skilled corps of engineers and scientists around the world, as well as a multibillion-dollar industry. That's because the traveling-wave tube and other vacuum devices continue to serve one purpose extremely well: as powerful sources of microwave, millimeter-wave, and submillimeter-wave radiation. And now, ongoing research into a new and potentially revolutionary kind of traveling-wave tube—the ultracompact and ultraefficient cold-cathode TWT—looks poised to deliver the first practical device by the end of this decade."
Light travels faster than sound. This is why some people appear bright until you hear them speak.........
No, happy accident. Kind of like how the old government buildings will protect their inhabitants from the radiation due to all of the lead paint.
Do not look into laser with remaining eye.
In my experience, when someone feels the need to insist that something is "surprisingly relevant", it's usually unsurprisingly irrelevant.
What a surprisingly relevant insight...
Do not look into laser with remaining eye.
And, they won't burn due to all of the asbestos. It really is a win-win situation. ;-)

I would *snort* at this, but my gasmask is in the way.
