The article is a little misleading. It mentions selling power back to the utility, but is not clear in the fact that the homeowner does not have to go off grid and have storage batteries to maintain and replace. You can get a grid tied system and a contract with the local utility that either gives energy credits for the excess power a solar PV system sends back into the grid. You can also have a grid tied system with battery back up. If the power in your homes particular area is reliable then battery back up is not really needed, spend the extra money that is not spent on batteries to put more panels on your roof.

1 If it did, would Nellis AFB install 140 acres of solar arrays at a cost of $100 million in order to supply one quarter of their electric, and save $1 million per yr? |

1 Even better is they talk about making your own and forget to tell you that the ones you make at home are nothing more than a roof mounted hot water heater. Solar should be left where it is powering small items around the house and office. While solar is great for small scale and portable applications it isn't for generating main stream power. It is reliant on having a nice sunny day and not much overcast. |

1 Could you show me in my previous post, where I said solar was 'friendly'. Where do you get your information? On the back of a cracker jack box? First solar, has a cradle to grave philosophy. They use more envioronmentally sound production processes and have a return, recycle program for old panels. Most of the product that is in the market place today is very capable of 50 or more years of service. Fair weather? B.S. I have had some very gray days and the solar system still puts out power, enough to make my daily requirement for the home. The system puts out more in the summer months with the angle of the sun and longer days. Less in the winter with a more oblique sun angle and shorter days. With a grid tied agreement with the utility, I have zeroed out on my electric bill for three of four years. This year it was hotter for a little longer than usual. Paid 37.00 for electricity this year. So Tina what is it that you have DONE, that you can tell the 'truth' about solar? NOTHING,right? You're a pathetic talking head that regurgitates someone else's opinion without question or research. You do nothing but are entitled to your first amendment rights to an ill concieved opinion based on folklore and ignorance. So you troll along making false assumptions and silly accusations without having any credible experience in the subject. Apparently are ill schooled in the basic sciences and some what lacking in common sense. Are you that lonely, that you have to troll blogs and start arguments to get some kind of human interaction? |

I know where you get your information. From the PR departments of solar panel producers. The fact is that solar panels still require some pretty toxic chemicals to produce them and even to recycle them. While you managed to make enought to get by that just makes you the exception to the rule. The average home would only be able to generate enought power on a nice sunny day. If your solar panels were in some place where they had to deal with snow and rain on a regular basis you would still be paying more than your making. They had people like you on national TV thirty years ago claiming that they didn't pay a cent and even made a little. Then all the others jumped on the wagon and discovered that solar was a lemon. Those who lived in cooler climates where it can drop belw freezing discovered that they were not only getting heat from those panels but had to drain them or wake up to a really cold shower when those same pipes busted. You want to talk about someone who "pathetic talking head that regurgitates someone else's opinion without question or research" you should just look in the mirror. But I sure the solar panel indusrty is making it more than worth your while to stir up interest and "favorable public" opinion. Even your handle tells the truth. Your no more interested in being honest when it comes to solar power than Bill CLinton is in his amorous affairs. |

1 I applaud your knowledge and support for the most logical energy source available.. From a personal point of view, I'd rather have the batteries than extra panels. I LOVE independence and you do not have it without some type storage. That's just another reason I strongly suggest using "Thermal solar" before any PV (assuming you need hot water) You can produce 2.5 to 3 times the power for the same outlay of cash. Tina is somehow mislead. A solar water tank can store enough hot water for several days. I'd be curious as to why she needs steam. Glasnos it is most unfair to base any logic on applications used by any branch of the armed forced or the government. The one you mentioned is certainly preposterous. Please remember the three ways to do something: The right way, the wrong way and the Army way. Jim |

1 Why do you keep going back 30 years, technology has incrementally increased both price and power outputs. What you think you know from 30 years ago is just wrong. My handle tells all what I have DONE and those who are not stupid enough to jump to conclusions of what I propose and support. All the information is available on the internet, so why are you so lazy that you can't at least find some purported 'fact', other than some one's bad experience with solar 30 years ago. As for snow and ice, there are a lot of folks in Colorado with both solar PV and solar hot water that would also disagree with you. |

More like very small fractions if any at all. The truth is that the current level of solar tech is pretty much the same as it was in 1979. While they have had made small changes it hasn't changed much and someone who worked on solar back then could pick up and still be current after thirty years. Compared to the changes in everything from cars to computers solar panels have not evolved. As for those people in Colorado, try asking them again in feburary. I bet the answer will be something you will not enjoy. |

No, that's a lie you tell yourself. Just because solar installation hasn't changed much in 30 years doesn't mean the technology hasn't. Racking systems, wiring systems, and protection systems are more integrated than before and much safer than the systems of the past. Three companies are printing solar cells, nanosolar, first solar and golbal solar. Dow chemical has just announced a new roofing shingle to be available at the end of next year or first quarter of 2011 called the powerhouse shingle. Then one can re-roof with solar. As for people in Colorado in February, several articles in Home Power magazine have interviewed some of those owners and they are quite happy with their systems, year round. |

1 I sure those people are happy because they don't have to rely on solar year round and they are getting thier name in the paper. The roofing tile idea has been in production for years and DOW just brought to rights to it. The printing tech is another computer tech orginally developed for making computer led screens. They have yet sorked out the connection problem. The fact that the wiring is being intergrated better has nothing to do with solar tech and more to with computer tech. In other words the solar people borrowed it from somewhere else. As for the rest I was hearing the exact same developments thirty years ago along with room temperature superconductors. They were talking then that it was just around the corner and thirty years later they still haven't turned that corner. The reason the solar installation process hasn't changed in thirty years is because nothing else about it has changed in thirty years. It is the same ideas that they used on satellites back in the sixties. |

1 Yeah, right. What is it that YOU have DONE Tina? Have you ever installed solar? How about a small micro hydro system? Put up a wind mill have you? By the way, there are room temperature superconductors. Cost of cooling in a high power application tends to turn utilities away from implementation. It seems that there are a couple of short haul links through densely populated areas that are actually using the superconductor technology. So Tina, what have you DONE? |

So you have any proof that they have actually found a way to make room temperature superconductors or are you busy making things up. The truth is with room teperature superconductors you would not have to cool them which makes me think your talking about the current crop of superconductors which have been used in afe scientific applications. Also if you wondering why I have been busy it i9s because we have had house guests from someone who was big on alternative power sources who had thier little wind generator fall over in high winds and the solar panels were not generating any power during a nor' easter. I have a feeling the tower is going to be scrap metal and the solar panels will never be called anything but a waste of money in that house. http://www.physorg.com/news134828104.html |

There are actually a number of ways in which solar energy can be used to power our homes other than what is attainable with the use of solar panels, e.g., the conversion of water to steam via direct sunlight to spin a turbine that powers a generator...This method would provide you with both an inexhaustible hot water supply as well as electricity though, as with direct solar to panel conversion methods, a storage cell, insulated water tank, or capacitor, would be required for those low-light, night time hours.
|
||||
In defense of "tina anne"...STEAM can be used to heat a home (via radiators) or to power a turbine to produce electricity...Just saying. |
||||
FWIW, operational "room temperature superconductors" are quite feasible IF they've managed to develop 'adiabatic' componentry, though the goal could be achieved through other, less inexpensive means, though real world applications would be limited given their inherent complexity. |
||||
That's an out and out lie Tina and WE both know it. Yeah, right, you had house guests that had a wind mill blow over. B.S. you obviously don't know any one who has had alternative energy. If you could force yourself back to my previous post, you'll see the current superconductor use in power application DOES require cooling, 600KV and 2000 to 2500Amps need a lot of attention to keep them flowing in a pre determined path. For YOUR information try looking up American Superconductor Corporation, they have been making protection switches for the power industry at least since 2005. This same company supplied a Chinese power organization with the superconductor to make a superconducting transformer. They have supplied superconducting cable for at least two jobs in New York. The LIPA project on Long Island and a short run of superconducting interconnect in Albany New York. What's the matter, the postman hasn't been to 'coon holler' recently to give you the word on superconductors? You keep saying 'what I heard', that's a lie you tell yourself, you've heard nothing. You will not hear anything but the voices in your head and you will be wrong a great deal of the time. You have the internet in front of you and still can't seem to comprehend what it is you read. There must be a Sylvan learning center near coon holler, look them up, expand your world. |

If it requires cooling it isn't room temperature superconductor but a high temperature superconductor. What you really need to do is read something other than press releases. After all no press releasse is going to do anything but make every product sound like the answer to every problem. I know several who have solar panels and wind generators. Who do you think they call when it isn't working right and the local electricion cannot figure it out. When they need someone who knows how to use a o scope and has experience troubleshooting. Between my husband and myself there isn't much. Speaking of which he got back from cutting up the old tower and is putting up the new one next weekend. Also if you want to talk about lies then why not talk about the lies involving solar and wind energy. After all they are still using the same hype they used back in the seventies. |

1 ROFL ... room temperature superconductors! You have blown all credibility ... When "American Superconductor" talks of HTS (High Temperature Superconductors) do you have the slightest inkling what temperatures they are refering? Of course you don't! They have managrd to raise superconductivity from 10 Kelvin to about 130 Kelvin ... Do you know what 130 Kelvin is? Minus 420 degrees Fahrenheit ... Does that sound like room temperature to you? Blow it out your ear! You know nothing. Room temperature superconductors indeed!! http://phys.kent.edu/pages/cep.htm |

1 What are you and Tina idiot twins from different mothers? I did not say they were room temperature for power usage, read the post again!!! Hopefully you comprehend a little better than Tina. It seems the HTS is actually useful as spike supression on protection circuits. As for Tina's grand response, an article from 2008, dated at best. She needs to look at the articles from 2009. While your rolling on the floor spray a little endust and clean the place up. As for credibility, your background is in what, Masters in B.S.? |

1 Wow! Typical liberal. Caught in a total lie and fabrication and you do a literary slight of hand. Room temperature superconductors DO NOT EXIST ... PERIOD! You claim they do ... LOL Just how do you plan on commercially using superconductors that need to be cooled to over minus 400 degrees fahrenheit ... genius? You must be a shill for American Superconductor ... making wild claims and outright lies. |
