![]() wrote Well, since frequency and phase out of a mechanical generator is RPM dependent, you would either have to have an infinite ratio transmission or a DC generator followed by a controllable inverter. I'll bet that they have the inverter. It would make sense, since they have to be able to jump around from system to system, with different voltages, and different frequencies. -- Jim in NC |

California is in the second or third round of this; I lose track. It will go down the dumper once again as the payback time, even with tax credits, is measured in decades. Get the total installed cost payback time under 4 to 5 years, then something may happen. -- Jim Pennino Remove .spam.sux to reply. |

Fortunately, there's more to on-site solar generated electricity than merely the time it takes to pay for the equipment. Why do you think Toyota Prius buyers were willing to pay 36% OVER book price for them when they were introduced? A lot of folks see it as their civic responsibility to take action to protect the environment. An then there's the independence from centrally generated utility power that redundancy provides. Get the total installed cost payback time under 4 to 5 years, then something may happen. With the 90% run up in petroleum prices over the last decade*, I look for electricity, in fact nearly all goods and many services, to reflect the rising energy costs with higher prices. With more photovoltaic fabrication facilities poised to come on-line, there's a chance of some price competition in solar generating equipment. So if rising Edison bills and reduced solar equipment costs fail to make the payback more attractive, perhaps the prospect of rolling-blackouts this summer will. :-) * http://www.wtrg.com/oil_graphs/oilprice1947.gif -- "We need an energy policy that encourages consumption" George W.

Why do you think Toyota Prius buyers were willing to pay 36% OVER book price for them when they were introduced? A lot of folks see it as their civic responsibility to take action to protect the environment. Because for the most part they can't do simple math and just look at the milage figures. That and people get sucked into hype. Why were people willing to pay 3 times the list price for a S&W .44 magnum after Dirty Harry hit the theaters? The next door neighbor was all hot to trot to buy a Prius and even rented one for a couple of days to see how they actually performed. He then sat down and ran the numbers. He bought a 2001 Toyota Corrola for his work car. Few folks are willing to **** away their own money to protect the environment. An then there's the independence from centrally generated utility power that redundancy provides. How are you going to be independant when the sun's not shining? Oh, you are going to put in a battery storage system and oversized collectors so your refrigerator keeps running at night and during the rainy season. Well great, you just pushed the payback time out another couple of decades. It is your money to **** away. Get the total installed cost payback time under 4 to 5 years, then something may happen.

There is already price competition in solar generating equipment. -- Jim Pennino Remove .spam.sux to reply. |

However, driving them off of the airport requires insurance that will make your auto fuel cost more that than the 100LL unless you are selling or using very large quantities of fuel. This is why most Av- gas trucks never leave the airport. The next best thing would be to get to know someone that has a fleet of 18 wheeler delivery trucks, and see if he will load one of the cells in his truck with some clean premium, and bring it to you at the airport. -- Jim in NC Most of the mogas STCs don't even require 'premium' |

Absent the invention of Mr. Fusion, there isn't going to be any electric powered trucks hauling carrots from Fresno to Chicago. Ahem: http://en.wikipedia.org/wiki/Electric_locomotive Electric trains work in parts of Europe because a long haul there is what would be called just down the road in the US and for local transit such as the Bay Area Bart system. Huh? Have you even done much train riding in Europe?? Today, one can take an electric train from London to Paris and thence to Marseilles. (For example; there are many others). You think that is equivalent to the local trains that just serve the SF Bay Area? Dream on! The European trains can go a good bit faster too. Even in the USA, you can ride an all electric train froom Washington DC to Boston MA? You don't consider that inter-city? Heck, the Pennsylvania Railroad had electric trains between New York (later to New Haven), Washington, Philadelphia, and Harrisburg almost 100 years ago. Yep, works where distances are short and population densities are high. You declared that long haul in Europe "would be called just down the road in the US and for local transit such as the Bay Area BART system." London to Marseilles, one example that I cited, is a good deal greater than the local BART system, or "down the road." European and US East Coast distances are tiny and population densities enourmous when take into context of the whole US. Really? Europe distances are certainly comparable to the US, even the whole US. And the population density of US places such as Southern Califoniia is a good deal greater than most places in Europe that have far superior rail coverage/service. Compare the distance and population density from Los Angeles to Chicago or San Diego to Maddison. California has a bigger county than some European countries. So does Massachusetts. So what??? Have you ever traveled from Detroit to Los Angeles on the ground? No, but I've travelled from Philadelphia to Seattle, Denver to Virginia Beach, etc. So what? You compared long distance trains in Europe to the San Francisco Bay BART system. Baloney! Take a trip to Europe and learn something. |
