It's a crapshoot depending on the CCI settings of your cable provider, but yes, they do. I have the quad tuner from Ceton, and from Verizon FIOS I get locals, expanded basic, and some of the premium channels with my mythtv backend. I recently rebuilt the box; it's currently running on Ubuntu raring, with an AMD A10 and 5x3TB in a ZFS array.

There's a small database that might be helpful:

You'll also need a listings provider; I use Schedules Direct, which just works but does charge.

(Under linux, you'll only receive channels with no flags or the Copy Freely flag. In the absence of CCI flags, the Ceton tuner will also respect the old school analog (macrovision?) flags that are ignored by clear qam tuners.)

Also: Power requirements (covered vaguely in TFA), efficiency, and thermal requirements, since this is an electric ion thruster. There are a lot of SEP designs, although I don't recall any others quite this small.

What I also didn't see in the article is whether they have or need some sort of MEMs equivalent of valves... will the ionic fluid boil off in vacuum without the voltage applied? At what rate? Does the ionic fluid degrade with storage, and will it clog the capillaries like an inkjet printer? How big are the pores, and are they sensitive to cosmic radiation like silicon?

Before gas stations, you bought gasoline at the hardware store in tins. Later on they added self-measuring pumps, and eventually they evolved into separate establishments. Also remember that roads were largely local during the early part of the automobile era, and it took a long time to develop a decent road network..

Yes, in Life+70 countries that can easily happen. In the US, anything published before 1923 is in the public domain. Anything from 1923 onward requires a lot of research, which sometimes leads to mistakes (as in the Rule 6 clearance referenced above, "The Escape", aka "Brainwave"). Actually, it's not so much a mistake as an oddity in the law. The first publication, as a serial, was not renewed. Only the later republication as "Brainwave" was renewed.
