When I worked on a console at a network control center, we used Plantronics Starsets. They were very comfortable. You would have to plug it into a cordless phone.
Yucca Mountain is located at the NTS (Nevada Test Site), where the USA has performed most of its nuclear weapons testing. So it isn't exactly a pristine example of desert wilderness. The site also has the most of the needed infrastructure and security already there.
1) subduction zones. Put the waste deep into a subduction zone instead of a stable region like Yucca Mtn. Instead of hanging around basically forever, the waste will be pulled underneath the Earth's crust eventually.
The problem is that you can sued for making true statements that some corporation or wealthy individual finds inconvenient or offensive. Do a google search on SLAPP (strategic lawsuits against public participation) or see this. You may win in court and end up bankrupt due to legal fees.
The telephone isn't a necessity of life either, but society has become dependent on it.
When I was a kid, you could see fire alarm boxes at regular intervals on every street. If there was a fire, you pulled the lever on the box and a clockwork mechanism inside the box sent a message to the fire department. It has been years since I've seen one of those boxes. The were made obsolete by the wide availability of telephones.
On a recent trip to a local grocery store, the store manager announced that they were having problems with their registers and that they would only be accepting cash until the problem was resolved. The problem was an outage with their Verizon high-speed data line. This had a noticable effect on the volume of business in the store. Their customers had become accustomed to using ATM and credit cards to make their purchases. Even the state issues welfare recipients something that works like an ATM card for food purchases.
You also have to consider the fact that nuclear explosions in space behave differently than nuclear explosions in the Earth's atmosphere. A nuclear device is primarily a source of soft x-rays. Since the atmosphere is relatively opaque to soft x-rays, the energy is converted to thermal energy and visible light by absorption and re-emission. This produces the flash, blast wave and thermal pulse. In space, you get a burst of soft x-rays and little else. The nuclear device would have to be very close to the asteroid, so that the soft x-rays were absorbed by the surface of the asteroid and converted into thermal energy.
I've read a number of articles that say that life on Earth will be destroyed in a few billion years by increased radiation from the Sun. The Sun's output is slowly increasing as it ages. At some point, the Earth will go into thermal runaway.
While CRTs for computers may be in a fast decline, they still dominate television sets. It will be a long time before LCDs have the size, brightness and price to compete in that market..
I believe there would be problems maintaining a spacecraft in orbit around the Moon. Lunar orbits are usually unstable. The Moon has a lumpy gravitational field due to the presence of mascons (mass concentrations). This was evident during NASA's Apollo missions when the orbital decays of the LEMs (lunar excursion module) left in orbit around the Moon were observed. See NASA Technical Paper 3394 for a study of the problem.
The ATSC HDTV standard uses 8-VSB modulation, providing approximately 19.39 Mbps of channel capacity. 1080i video will use almost all of that. See the FCC DTV FAQ.
Here is an interesting article on the HeLa cell line, derived from a young woman's cervical tumor in 1951. The cells are amazingly resilient and prolific.
One of the advantages of older processors is their lack of cache. This is important if deterministic timing is a requirement. The main engine controllers on the Space Shuttle use redundant pairs of 8 MHz Motorola 68000 processors.
Does the circuit still work properly if the temperature increases by 10 C? What if the FPGA data file is loaded into an FPGA from a different vendor or an FPGA fabbed on a newer process?
The FCC wanted to take away some of the UHF TV spectrum for public safety, land mobile and other uses. The broadcasters didn't want to lose any spectrum so they said that they needed it for high-definition TV. They pointed out that the Japanese and Europeans were working on HDTV, and we didn't want to fall behind those sneaky furriners. It worked, they got to keep their spectrum on the basis of a vague promise to broadcast in HDTV, someday. Fast forward to today, those same broadcasters are now bitching about how expensive HDTV is and how they need extensions to the FCC deadlines for switching to HDTV. The transmission standard (ATSC) has severe problems coping with multipath (ghosts on NTSC). The cable companies are trying to ignore the issue of digital must-carry, they would rather have 500 channels of PPV, HSN and WWF in sub-NTSC quality digital cable. Hollywood views this as their golden opportunity to push encryption, copy protection and conditional access. The networks aren't eager to spend a lot of money on HDTV production when there are so few ATSC receivers (less than 200K) in American homes. Electronics retailers are pushing "digital ready" TV sets and DBS receivers, but ATSC receivers are hard to find, buggy and intolerant of multipath.
That is what regulated common carriers, such as your local telephone company, are for. It doesn't have to be federalized, just regulated. This is usually done at the state level. The telephone company can't disconnect me for having views that people find offensive. On the other hand, my ISP can cancel my account for any or no reason. This isn't a big problem with dial-up ISPs, where there are plenty of competing ISPs. It's in the broadband arena that the problems are more serious. There are likely to be few alternatives for the broadband customer. Cable companies tend to have the attitude that their customers are mindless proles, who should be happy that they are allowed to surf the web in the company's "walled garden". They dream of partners, synergy and pay-per-view.
One common technique is to have a closed primary loop containing distilled water. This is connected through a heat exchanger to an open secondary loop that contains ordinary water from a river, lake, etc. I've seen this used to cool high-power radio transmitters.
Tell Mr. Bunny to deliver the green Megaman to the Big House at 0900 on Wednesday.
How are they going to find that message, or understand its significance? The NSA intercepted and decrypted a large number of Soviet diplomatic/intelligence messages in the 1940s (VENONA). Despite a large amount of work, the identities of many of the agents referred to in the messages are unknown.
I'm not an RF guy, but I work around microwave antennas and receivers. Combining multiple feeds, from one antenna or multiple antennas, is tricky, esp. at microwave frequencies. For the frequency of interest, the feeds must be in phase with each other. You need to be able to adjust the phasing for maximum output from the combiner. If you want to do interferometry, it gets a lot more complicated.

One of the advantages of older processors is their lack of cache. This is important if deterministic timing is a requirement. The main engine controllers on the Space Shuttle use redundant pairs of 8 MHz Motorola 68000 processors.
The conservative approach is to use both link and end-to-end encryption.
