Well, that is the crux of the problem: tank type water heaters are just systems with buffers. They can afford to have lower power heating elements in them because they can afford to run longer to smooth out the demand versus production curves. Tankless removes the buffer. With electric elements, the efficiency is probably going to be equal no matter what, and the cost difference becomes: can the increased cost of install overcome the standby losses of a tank? It usually can when you amortize the more frequent replacement costs of a tank over time.
Did you include the costs of replacing the tank heater 5 more times in that 30 years?
Solar is a good add-on to regular heating. You use the solar to extract as much heat as you can, and then you use some conventional heater to bump it up as necessary. They have a system of heat pipes installed in evacuated glass tubes that can collect a pretty good amount of heat out of the sky, even in relatively cool ambient temperatures. But it is expensive, and probably only worth it to people who want to live off-grid.
The worst part about this is that the DA office doesn't seem to understand that "Stand Your Ground" is just an affirmative defense against a crime, not a magic spell that means someone can't be arrested.
Hispanic just means from an area with a cultural connection to Spain. That means different races can be Hispanic- just off the top of my head, they could be Spanish, native American, meso American, Jewish, Filipino, Caribbean. But I agree, the usage in this case is ridiculous.
The same way you can recognize someone's voice whether it is in person, across the room or on the telephone. The distinctiveness of a voice is about overtones and the various proportions of them to each other. The vocal cords and shape of the skull don't change.
This would easily be solved by law enforcement arresting and charging him with something so that the courts would have the opportunity the do their job.
I agree with #3 100%. I was at a party at a "rich guy's" house recently, and the house wasn't ostentatious, but it had the little things. Like for example, your recessed media cabinet. The dude actually bumped out an exterior wall so all the media stuff would be flush with the interior wall.
The "has limitations" is the same for both. You choose a unit that has a burner that will provide the desired temperature water under the usage scenarios envisioned. A tankless just has one less variable. With a tank heater, you can fill that hot tub, as long as the hot tub is 1/2 the size of your hot water tank, but then you get no hot water until the tank has recovered. With a tankless, it will give you a temperature rise versus water flow. Just size it correctly and you are good to go.
If you are ripping out a perfectly good tank heater to put in a tankless, then it probably doesn't make sense. But if it is time to replace anyway, it doesn't cost all that much more. The big benefit is not having to keep a giant tank of water at temperature for many hours a day. Every time your water heater fires up when you aren't using water, it is money out the chimney. Plus, their burners are generally more efficient at turning gas into hot water. The exhaust coming out of the one I installed is not much warmer than room temperature. And they are not nearly as complicated as installing homemade windmills...
I put a tankless in for my mom a couple years ago, and it doesn't have any of those problems. It senses the water flow and adjusts (something) to make sure the water output is the right temperature. From handwashing to showering, the temperature is rock solid.
But yes, point of use is a neat idea in some cases- her house is configured such that the kitchen is a long way away from the bathrooms, and that's where the tankless is located. So it takes a while for the hot water to make its way through the pipe. A $200 point of use electric heater would be great for that, but she wasn't interested.

It is easier to think about in the transmit mode of operation, and then receive is just the opposite. Alright, you know how you can take digital data on your computer and convert it into sounds coming out of your sound card? Same thing but with higher (faster) radio frequencies. Reversing it for receive means that you hook up your "microphone" (antenna) to the line-in, and tell it to record. Using the raw "wave" file, you can filter out the signal you want, and then process that signal to get the data out.
Facebook is great to stay in touch because you can broadcast things instead of narrowcasting them. An acquaintance can type "baby #4 arrived, $name, $weight, mom and baby are fine" and all their friends know about it. Done.
The point is that by plugging the easy holes, you force the terrorists to improvise and cause themselves to be more easily caught, or at least to fail.
Schneier's flaw in reasoning is that to be more intelligence driven, you have to trust your intelligence. This gets into Rumsfeldian unknown-unknowns territory. We can only know what we can know. There are things we can't know.
I agree about the keyboard. I had to use an iphone to type recently, and found it to be awful. The word guessing thing was super annoying, and while I don't claim to have the largest fingers in the world, apparently they are not as pointy as other people's. When I try to center in on one of the letters, I'd hit all the letters surrounding it and the phone would guess incorrectly about half the time. It was torture.
I think you hit on a point: a lot of the iPhone's success can be tied to iTunes and the fact that it is really an iPod that makes phone calls. Anyone with an investment in that technology was going to choose iPhone just because it was easier.
I agree, a better browser would have helped RIM maintain market share.

Why should they be afraid of being recognized?

Not any more. With the direct vent or condensing burners they use now, the burner is just as efficient as a regular tank type heater.

Again, why? Why do they want that?
You are sort of right about it being a simplification, but it also has usenet and forum qualities that make it unique. And it has games.

Sorry. Would "tap" have been easier to understand?
My question for this position is always: "why?" Why would the government want a bunch of sheep?
1- There was a recession and a very slow recovery. That's going to eliminate a lot of travel.
2- Fuel prices have been going up a lot, and fuel is a big component of the price of an airline ticket.
Maybe some of the decline is due to security fatigue, not I doubt it is very much of it.
How about you explain how speculators in the futures market can change prices?
