Very, very few residences in the US have 208V available. Most have 240V. 208V is a result of a phase-to-phase connection on a 240V threephase connection, which is _not_ typical in a home.
Homes are typically served with 240V split phase, which is 120V phase to neutral, and 240V phase to phase.
As a point of interest, many lighting circuits in commercial settings are 277V - that's from a 480Y/277 3 phase system.
Try being stuck in a tunnel for 4+ hours. Talk about an exhaust-induced headache -- and I still had to get to Richmond! I swear people were swooning from the fumes.
Remember that in the US, we have states where you can drive 160 miles and still need another full _workday_ of driving to cross it (Texas is 660 miles wide and 790 miles tall. At 60 MPH, that's another 8.33 hours to cross it, and 10.5 do make it down to the Mexico border). Alaska has twice the area, but few roads.
Those poor folk will have the "I'll have to reinstall the OS" mantra slowly and painfully steeped into their brains via ex-Soviet brainwashing techniques.
Even then, they may break out of their 'conditioning' and yell "Just buy a Mac, for Pete's sake!" at which point they will be led out the back door of the store and mercifully put down with a single shot to the back of the head.
Good idea, but that would involve a considerable amount of bother, since the heater is propane-fired and I really don't want that sort of appliance in the main part of the house. The heater I have is a Rinnai 7.5 gal/min model that's in the garage (where the flue can easily pass thru the outside wall).
That said, I have considered putting small electric on-demand heaters under the sinks to generate hot water until the big dog kicks in, but again that will probably involve pulling some manly wire.
I'm on well water, so the extra water isn't "wasted" in the classic sense; it's just yanked from the ground at point X and put back in the ground at point X+200ft.
I just recently picked up a 1906 edition of this book on Electricity and Magnetism. Having a scanned version available in no way diminishes the value of my hardback copy - in fact, it allows me to read passages that might otherwise be obscured by schmootz.
Thanks for the good information. I especially like the failure statistics - the ESBWR is approx 1000x less likely to experience core damage than a typical BWR/4 plant! From the ESBWR wikipedia article: General Electric has recalculated maximum core damage frequencies per year per plant for its nuclear power plant designs:[2]
BWR/4 -- 1 x 10-5 (a typical plant)
BWR/6 -- 1 x 10-6 (a typical plant)
AP1000 -- 5.09 x 10-7 (received final design approval from the NRC)
ABWR -- 2 x 10-7 (now operating in Japan)
European Pressurized Reactor -- 6.1 x 10-7 (being built in France & Finland)
ESBWR -- 3 x 10-8 (submitted for Final Design Approval by NRC)
Dominion Virginia Power will be building one soon (2010), and expect to be online around 2015. They already have their federal ok for the additional reactor at that site. Note that it's a Boiling Water Reactor, not a PWR, so maybe there's no huge pressure vessel required.
Read this analysis' take on the proliferation problem - breeders provide a _lower_ proliferation risk than current designs.
We continue to build up proliferation-prone stockpiles of high-level waste while politician's heads are in the sand regarding modern, non-PUREX reprocessing. It's sad, really.
I have two reactors in my (extended) back yard, and they're building a third. More power to them (no pun intended). They're 20 miles upwind of me. I also have two more 50 miles southeast of me.
... uses natural circulation with no recirculation pumps or their associated piping, thereby greatly increasing design integrity and reducing overall costs.
and
All of the safety systems operate without using pumps, thereby further increasing design safety reliability and reducing costs.
I wish it was going to be an IFR (breeder), but maybe I'll see them in my lifetime.
I bet the final version will be the same form factor as a regular plug, except that it contains a synthetic diamond or sapphire window and an IR laser diode capable of producing the required energy density when pulsed at < 33.3 Hz (8,000 RPM).
Similarly, combining the hydrogen and carbon in slightly different configurations leads to a solid at room temperature. Look at the waistlines of many Americans (myself included) for examples of this magical substance.
Does anyone out there know the formula for calculating the burn time of a single wick embedded in a given amount of human depot fat? I've always wondered how long I'd burn with a wick sticking out of my belly button.

If the cops tried to return that POS to me, I'd refuse it.

Spraying the problem with perfume will not make it go away.
Minor point: Sagan is still [treated as] a hippie, even after his death. As much as he smoked, I bet he's running around heaven still baked.
Pah. Casting a Tiger is easy.

I love to see people wince when I use the phrase "I clubbed that thing like a baby seal!"

Isn't that what Crocodile Dundee and Sue (the woman from New York) ate in the outback?

Solar thermal is much more efficient and has the advantage of being able to use heat sequestering with molten salt or oil...
Plus everyone can deep fry their turkeys for free.
I'd say a young boy over a bad rector are a worse combination.
Did you find John Parker, John Yaya, John Smallberries, and John Big Bootay?
0 miles. I'm all up in it. In fact, the Museum and White House of the Confederacy are right up the road.

Do you have any idea how filthy your "little Briggs and Stratton" is emissions-wise?
Let's not put those on the road, please.
How do the fuel cells on the Space Shuttle overcome these problems? I can't think of a more harsh environment, especially vibration tolerance.

130 F is right between rare and medium rare. I wonder what well done feels like.
