    I can see AC to the doorstep a big efficient whole house power supply that has 12vdc and 48vdc rails that are distributed thorough the house and battery backed, and few 220v "appliance circuits" off the AC.

    48V and 12V lines are far too low to be sage and/or sensible. Remember that the power used is equal to the voltage times the current and that the heating of the wire carrying the current goes as the square of that current. Typical house wiring is good for ~30A of current and supplies several plugs in a room typically. With a 12V circuit you limit the power of all the devices connected to this circuit to 360W vs. the 6.6kW you get now (or 3.3kW if you live in North America). Even with a 48V circuit you only get 1.44 kW. The result is that either you need to rewire the entire house with massively thick, and therefore expensive, cables to carry the far higher currents or you need to use a higher voltage for transmission. Even the factor of two reduction between Europe and Canada/US is noticeable for some devices: electric heaters are far punier than their European counterparts, kettles take far longer to boil, and Electric lawnmowers are practically useless etc. If you drop the voltage by another factor of 2-10 below even Canada/US then almost all devices will be impacted.

    Basically, time to split the union of lighting and motor power that made Edison's vision possible, and go to low voltage LED lighting while leaving the 110 volts for everything that needs more than some tens of watts. Also a network of data ports that supply USB voltage/currents for our computerized needs.

    DC in the home is only viable due to recent advances in power silicon. AC has its problems, but the genius of AC power is that you can controll it with nothing more than carefully arranged windings of wire and big chunks of metal. Transformers, inductors, capacitors, and resisters can all be made with nothing more than properly arranged and chosen wires and metal blocks. There was no practical DC-DC conversion in Edison's day. Even AC/DC conversion was tricky, often requiring an AC motor with a shaft mechanically linked to a DC generator.

    Edison did not have the IGBT http://en.wikipedia.org/wiki/I...

    Today, that's different.

    You can make tiny, tiny, cheap little AC-DC or DC-DC converters that are dozens of times cheaper and many more times efficient than their counterparts made even a decade ago. What used to require large arrays of MOSFETs and many many pounds of expensive copper windings (And the design/volume/heatsinks/fans to deal with all the waste heat!) is now handled by a much smaller transformer, a handful of inductors, and some advanced switching silicon controlled by a fairly smart processor. You also, thanks to increased efficiency, don't need to overbuild with expensive heat tolerant components so much. (Heat shortens component lifetimes, particularly caps)

    And they're already deeply commoditized because, guess what, the chinese are big in to solar. (They know they are going to need it. They're quite aware that traditional energy can't economically fully meet their future demand.)

    I still have my WWII surplus dynamotor designed to convert low voltage DC to high voltage 400 hz for aircraft purposes. hasn't been too useful thus far, but someday might come in handy.

Anybody who can explain why will have my gratitude. (Can't be for compatibility with the battery operated mowers, because it's a 110 v DC motor, while the battery models top out at 48 v).

    don't be so hasty, hipsters and lumbersexuals need to promote something they understand, ie. not heavy chemistry.

    I'm researching organic data integration and processing devices, made of organic materials, largely proteins suspended in solutions and gels, powered by oxidation of simple carbohydrates. Rather than purely electrically, signals will be transferred by a hybrid chemical/electrical process involving transfer of ions between compartments of conducting saline solutions, isolated by nonconducting layers of hydrocarbons, with said transfer both dependent on and altering the electric potentials.
    Data will be processed in a revolutionary manner, avoiding the bottlenecks of the von Neumann architecture; holistically, rather than using separate memory and processing areas. It will be built of similar microscopic processing units, each of which integrates several inputs into one output, handed off to similar units. this provides for a great deal of plasticity, as well as failure tolerance, as functions are mostly not locked into a single substructure, but can be rerouted if local damage occurs.
    this model can be easily enhanced to provide for the unit having limited sensory capability, mobility and a self-maintenance capacity which allows it to seek and consume fuel when necessary, avoid damaging environments, etc. etc.; to some degree it will be self-programming. Ultimately new units will be constructed and initially programmed by other similar units.
    Right now my goal is to investigate this latter function, of replication of new units as a result of interfacing between previous units. At this stage, I am more interested in the initial steps only of the process, and do not intend production of actual units, which would strain research resources. This would make it possible to study a large number of these initial interfaces with many of the numerous working examples locally available for study and experimentation in this area; however I currently lack the funding to engage them in this activity for sufficiently detailed experimentation and analysis, so I am seeking grants.

    You've grossly mischaracterized me and my stances.

    I said I feel an obligation to align my vote with my moral stances on issues, which I was pointing out comes at the cost of being able to align my vote with any of the other stances I may have. I never said that I find my own beliefs to be unfair or wrong. As you implied, it'd be ridiculous to knowingly hold onto ideas you're aware are wrong.

    And sorry if this is a bit of a soapbox issue for me, but who said anything about hating gays? At least for me, when it comes to the hot-button topic of marriage, my firm stance is that the government should stay out of it, regardless of which way someone swings. Legal unions should be available to anyone that want them, and should come with all of the expected tax breaks and other legal benefits, plus all of the expected legal obligations and financial responsibilities. In contrast, marriage is an entirely separate concept that means different things to different people, so it's best left to individuals, organizations, or religions to decide whether they want to ignore it, treat it as a pleasant tradition, or incorporate it into their religious practices.

    Speaking more broadly, sure, I consider homosexuality to be a sinful practice based on what the Bible says, but I could say the same about eating too much, lying, getting drunk, stealing, or even just engaging in lustful thoughts, so it's always struck me as incongruous that homesexuals get singled out as being a group that I allegedly hate. What about the others? Why don't I get accused of hating them too? After all, from what I can tell, I have just as much cause to hate drunks, gluttons, and people with filthy minds...

    ...which is to say, I have no cause to hate them at all. Everyone sins on a regular basis, myself included (including some of the sins I've already listed!). Being a sinner is not a valid reason to hate someone, and thank God for that, since if it was we'd all be miserable, self-loathing people. The Bible isn't filled with kumbaya love, but it does say that God loves us all, so who am I to hate those He chooses to love? The Bible also says that God hates sin wherever it is and that even one sin is enough to face judgment, so who am I to act as if I'm in any way superior when I'm subject to the same judgment? And the Bible says that it's God's job to judge others, not mine, so I have no business being judgmental, let alone hateful towards anyone else, regardless of their sexual orientation.

    I get that there are religious types who can and do engage in hateful attitudes towards homosexuals, and it's hopefully obvious by now what my stance is towards the validity of those attitudes. But what about our shared responsibility to assess people on their own merits, rather than on the basis of a convenient stereotype that lets us marginalize them? As a site, we're too quick to apply the "hateful and intolerant" religious stereotype label to folks around here as soon as they profess a religious belief, without ever finding out what they actually believe.

    Yes, stereotypes oftentimes have a basis in reality, and you'll run into people for whom the stereotype is a good fit, but that doesn't excuse us to dismiss people according to racial, religious, gender, national, or sexual orientation stereotypes that don't fit, just because they fall into one of those categories. We all should be making a concerted effort to stamp out bigotry, whether it's aimed at someone on the basis of their religion, their sexual orientation, or some other irrelevant piece of data.

    that's reminiscent of the argument, though, that the right hating Obama and hating his policies is just like the left hating Bush and his policies. The difference is that, although the left didn't really like Bush, the real hatred came as a result of his policies; the war in Iraq, and the conversion of the budget surplus into a deficit. whereas obama was the satanic muslim socialist america hater from day 1, and so even a recycled republican gem like the ACA became the fruit of the poisoned tree.
