The screed on driving everywhere is easy to understand if you've never been the U.S. Lots of Americans live in cities and can commute on foot in places like Manhattan. That is simply not practical in a state like Kansas or Iowa. The countryside is vast. Hell we have a state the size of the entire European continent. Texas is the same size as France.

The linked article (gasp I read it first) notes that hydrogen can be generated from any electrical source, even nuclear. Electrolysis is an energy intensive process - using the electrical output of a nuclear plant to crack water would be a waste of useful electricity. Radiolysis, the breakdown of water into hydrogen and oxygen by the action of neutrons, is a by-product of the nuclear reaction in water moderated reactors (virtually every commercial nuclear plant in the U.S.).
Using the nuclear reactors to make electricity, sans greenhouse emissions, and siphoning off the hydrogen evolved from radiolysis is a much more efficient solution. One pound of nuclear fuel ( 5% U-235) can generate an absurd amount of hydrogen. A lot more than the electricity evolved from that same amount of fuel could through electrolysis.
No need to design a complicated solar array when a simple RTG will do. They are essentially solid state with no moving parts at all, making them very easy to assemble on the surface of the moon.
Additionally I am unfamiliar with the efficiency and durability of Lunar era solar cells, it may well be that the RTG was a more reliable power source.
Solar panels work great when you're this far into the solar system. From Mars and beyond the solar intensity is much lower and solar panels would need to be prohibitively large and heavy to provide the same amount of power as a 45 pound radioisotope thermal generator.

Murphy's law says that as soon as I buy one standard compliant model the entire market will shift to the other.
Given the current standards mix I have to disagree with the article's claim that DVD's will become a standard within a year's time. None of the profiled drives offer totally compatibility with the competing +/- R and RW standards. There are several drives from other manufacturers that support all four formats for about the same price though.
Radiolysis is a very efficient means to crack water. An ultra-low emissions system would use reactors to generate both electricity and large volumes of hydrogen as a by-product. The electricity has obvious uses and the hydrogen can be used as a portable source of energy for combustion applications, etc.
It would require a large investment in new reactor types but in the long run it would be a very cheap and clean method of driving a hydrogen economy.
Ill-informed public opinion will be the greatest obstacle though.
Except for that whole reduced boiling point thing.

The body can stand immense positive pressure, but nasty things happen with very low pressures. The boiling points for things like water (which your flesh has in abundance) come way down. Check out the water phase diagram sometime. Interesting things happen at sufficiently low pressures, like room temperature boiling, sublimation, etc that are beyond the normal intuitive understanding of everyday materials.

TiVo is, in my humble opinion as a TiVo user, the best thing that's happened to TV. Posters who complain about the fee, saying that the same services can be had for free simply don't get it. It's a luxury item, my monthly fee pays for a service that I find highly valuable, and for $15 a month it's well worth it.
If you're interested in assembling your own computer PVR that's great, go ahead. But for me, and tons of other TiVo users, the value of TiVo can't be beat. The time it would take to cobble together and support a home-rolled box is non-trivial and personally, my time is worth more than the paltry fee I pay each month.

That's true for any steam plant. Thermal efficiency for fossil and nuclear plants is about the same ~ 34% (with fossil plants being slightly more thermally efficient due to superheating). That's due to thermodynamics and can't really be changed.
Zero emissions in the context of power plants refers to greenhouse gases, arsenic releases, air pollution releases, etc. Fossil plants produce millions of tons of these emissions each year.
Look at it another way: the thermal and water vapor effects caused by power plants cannot be used to distinguish between nuclear and fossil fueled steam plants. If you were shown statistics on waste heat from various power stations you would not be able to distinguish nuclear from fossil stations. If you were to look at CO2 emissions you'd see a night and day difference. Sort of a Turing test for power stations if you will.
There are currently 442 operating nuclear power stations in the world. Assuming they produce an average of 1000 megawatts electrical output each gives a total capacity of 442,000 megawatts. The total thermal output would be approximately three times this number, (132600 megawatts) roughly 1.33 terawatts.
That's the total thermal output... the waste energy must be some fraction of that total number. We assumed that 1/3 of the thermal output was converted to electricity leaving a little less than.9 terawatts of waste heat being released by nuclear stations alone. Nearly *one* terawatt, not terawatts.
I'm just nitting back but your point is a valid one.
Exposing living tissue to radiation without the attenuation caused by the epidermis would result in higher doses, but the smoke itself is a much more immediate threat to your health, as your sagebrush experience demonstrates.
A 1000 megawatt (that'd be a gigawatt) power station generates approximately 3400 megawatts of thermal power (that'd be 3.4 gigawatts). A terrawatt is 1000 gigawatts, or 1,000,000 megawatts.
You're still talking about a few hundred millirem per year... only about twice what you'd receive from the sun at the same elevation. You need about 50 REM in the space of a few hours to alter blood cells. Inhaling the smoke would lead to slightly higher dose rates, but in that case the smoke will kill you long before the exposure does anything to the living tissue.
It's based on the spam that *you* receive. You train it on the messages that you actually receive, based on what you think counts as spam. I'm totally enamored with Popfile (a stand alone Bayesian mail proxy). It's just about bulletproof now after one week of training.
Of the three types of decay radiation alpha particles are the safest, then beta, and finally gamma. Alpha particles are bare helium nuclei while a beta particle is basically a free electron. Alpha cannot penetrate the skin, and will only travel about 1 inch in air before it snags a couple electrons and turns into regular helium. Beta particles are much lighter and tend to have higher energies. They can penetrate skin but will be shielded by thin layers of metal or plastic. Though in a battery casing this wouldn't matter much.
Here's an idea. Give them their law, along with the opt-out model, but tack in a stipulation that all legal spam has to have an identifier in the header that clearly marks it as spam so I can filter it out.
