    yes and current networks have been built over a day, look right, occupy no space and need no transmission lines, right?

    I didn't say we shouldn't add them, I said that environmentalists would argue that we shouldn't. After all, didn't I comment positively about the massive, expensive, infrastructure upgrade that Con Edison(NYC's power company) is in the process of installing. I'm all for infrastructure improvements.

    There are projects that propose use of DC instead of AC and this could actually decrease power loss at transmission.

    You are wrong there. The whole reason we went with AC is that the transmission losses are lower. Edison was for DC, but Westinghouse and his genus Tesla convinced the world, correctly, that AC is the better solution.

    The actual power stations based on solar power can be built (for Europe) in Africa and transmission lines towards users in (also) northern Europe.

    What about the Germany's massive government support for solar electric? There are tons of solar cells being installed all over the place there in Germany.

    In northern Europe one can built (as it is currently being done) wind mills in coastal areas. This can offset part of the problem with lack of energy if clouds obscure the sun and/or the wind goes elsewhere.

    Why not simply install large batteries? American Electric Power is doing that in places in Ohio. What about flywheels or ultra capacitors? EEstor says they'll have amazingly power dense ones available soon, and they convinced an American defense contractor to contract to buy them. Those technologies would make solar and wind much more viable for the local area; ie even northern Europe.

    This all may be not nice for average tourist or local resident looking at the wind mill or solar panel so are however highways, train lines, power lines existing today as well as climate changing burning furnaces of any traditional power plant (yes human activity changes climate - for those that do not believe maybe they should buy two weather stations and start measuring temperatures in and outside town for a simple proof).

    Um, climate is long term. What you describe is weather, more specifically, the heat island effect. While that is certainly true, it's not climate. I do agree with you that human activity is effecting the Earth in many significant ways.

    Now all this may be unimportant - the time when currently used fuel for power plants will be gone and something will have to be done is approaching however - we can just as well start doing things now when it is not so troublesome.

    Why such gloom and doom? There is tons of money to be made, and tons of investors and venture capitalists trying to get their hands on all that energy money. I work in the financial industry and see it every day. Have hope; greed will solve this one.

    But there were plenty of people alive when Europeans found the place; long after the deforestation. Also, plenty of people live where there are no trees.

    In other words, NYC is "solving" the "problem" of electricity wasted into heat (by resistance) by wasting a ton of electricity running a gigantic fucking A/C unit 24/7... which coincidentally, is just a heat pump. Is it just me, or is this really silly to start with? You might think so until you consider some details I didn't mention. The amount of energy wasted on cooling the superconductor is significantly less than the amount of energy lost in transmitting the power. Proper insulation does help, along with the fact that we are talking about a few limited, but VERY LARGE underground wires. In a single wire in your house, not that much power is wasted say heating up the wire that say supplies your tv with power. Touch it, it's not warm. The problem is when you try to send enough power for say Manhattan Island where you have roughly 10 million people at work during the day. Then you are sending A LOT of current, and it's the current that heats the wire. That same copper in your tv power cord ain't that good when you put a lot of power in it, and your transmission losses get huge. By cooling a special metal turning it into a superconductor, you eliminate those losses. Thus by spending a bit more energy on cooling, you save a lot more overall by using the material without resistance.

    Read up on power losses on high power transmission lines and superconductors; then you'll understand how they make sense in limited installations.

    the thing that will kill your idea is power transmission. The US together with Canada has a huge well interconnected grid, and yet, it is really 2 grids separated by the Mississippi river with a few interconnects across it. It's then broken down into several smaller grids, like the one that supplies most of the Mid Atlantic states and parts of Ontario Canada. As you might remember, that sub-grid went down about 4 years ago even though the rest of the US/Canada grid was fine. That grid failed because we didn't have enough transmission lines to transmit all the power around the sub-grid when one large transmission line was knocked out due to an accident.

    So what's my point, to do what you want would take A LOT more transmission lines. People don't want to build them, and environmentalists would be upset with all the land that would have to be given over to them.

    The other problem is transmission loss. You lose power in a wire when you send electricity to it; it literally heats up the wire a bit. This is why you see those big transmission lines sag a lot in the summer, and a lot less the rest of the year. Sure, the summer heat does some to the wire, but most is the extra summer load. Superconductors would help, but we(humanity) can't make ones that work at room temperature; or even close to it. We're getting closer though, and are actually using them in limited places. NYC is currently installing them in parts of the city; along with the expensive cooling system to make the wires work. You also are starting to see them pop up within the sub-stations around the US. I think other countries are starting limited usage of them as well, but I can't recall any examples.

    Most solar thermal plants use some medium that the sunlight heats up. That medium is pumped close to the bottom of a water tank to generate your steam. The thing is that the sun heats up the stuff a lot, and you can store that medium in a well insulated tank. You can then pump it from that storage tank to the boiler after the sun goes down. Even the early versions setup in California in the 70s did this, and that plant is still running today; albeit with some upgrades. Beyond that, as another commenter pointed out, using some electricity to electrolysize(sp?) water into hydrogen to be burned in an ICE or better yet used in a fuel cell would get you power after hours just fine.

    The good news is that you CAN'T crash into it. Although there are tracks that go to Grand Central, AMTrack does not currently use them; only the commuter railroad Metro-North; including the Connecticut line, does. AMTrack, including the Acela, only goes into Penn Station on the other side of town. More to the point, though, in the case of both stations, the trains go UNDER the station, and not into it. There are plenty of choke points to include the tunnels from Jersey to Manhattan that would be used to stop any high-speed train. Beyond that, the fact is that a whole new track would be needed to set this up. I honestly doubt they would use the beautiful old Grand Central Terminal, or rather ugly Pennsylvania station, because you'd have to modify the existing tracks quite a bit to support the Maglev tracks. The problem there that the tracks that support AmTrack, used in Penn and currently not used in GCT, are also used by the local commuter trains; the Long Island Rail Road goes into Penn, and soon(10+ years) thanks to a $20+ billion construction project, the LIRR will go to GCT. Those trains which bring many millions of people into and out of the city each day would have service limitations and interruptions. That's why I don't expect to see any MagLev trains going there any time soon. Of course, I sure would love to see it; especially if that meant that they would upgrade those commuter trains as well. Also, there are tunnels that enable all the trains, subways too, to turn around underground. The two stations have branches off of the main transit tracks that do have ends, but the main tracks don't end. I guess, you could probably have your train jump the track if you took the turn fast enough.

    Actually, I thinks it's the immense similarity in our two peoples that is the source of the problem. Both the French and US Americans have a bit of a chip on our shoulders about our place in the world both culturally and, let's say, militarily. We both would like hegemony over the whole world. To a real degree, albeit it seems to be fading at the moment, we have it. They did for a short time, but have always been second best. First they were second to the Brits, and then, after helping us separate from the Brits, we usurped the Brits for hegemony. The French never had their chance in the sun; except again for a short time when Napoleon was running things. In a sense, the general dislike of the British and the French for each other was transferred to the US and the French. Ironically, since the British are ruled by the Normans, and the Normans whom are Franconised(my word) Vikings, the British are very much culturally tied to the French. Again, due to our cultural origins in England, so is the US. That only progressed through time with the US-French relationship. After all, the French Revolution was inspired by the American revolution; something itself partially sparked by French Renaissance authors; and arguably triggered by the expensive French support given to our revolution while they still supported other parts of their ongoing war with England. Take America's most pure and idealistic symbol, the Statue of Liberty, a gift from France. Then there is the often referred to, but rarely read, De Tocqueville's Democracy in America; considered the definitive work on our political environment. Again, written by a Frenchman.

    Admittedly, my rant is mostly about French ties to the US, and not as much the other way, but I'm American, and don't know that much about how we've impacted their culture. Still, I will say the willfulness and obstenance that both ascribe to the other is both well deserved as a description and accurate. I consider the US to be the younger sibling to both England and France; as such we love to hate them, but come to there defense when needed; that is all 3 parties there, even if the Brits and the Yanks generally get along better.
