The billboards along I80, going past the indian gaming sites in California, headed towards Nevada, increasingly show glowing, enraptured asian faces "winning big." Just a few blocks from here, on Saturday mornings, about a hundred Chinese folk gather on the sidewalk, waiting for the chartered bus to Reno. I've heard the serious claim it's genetic. Can't stand to gamble myself. John

Yes, I think you're right. There are a few articles about LVS working the asian markets with the "Las Vegas" name. http://www.investors.com/NewsAndAnalysis/Article.aspx?id=528846&utm_source=feedburner&utm_medium=feed&utm_campaign=Feed%3A+BusinessRss+(Business+RSS) "Its name and headquarters may shout Las Vegas. But for gaming giant Las Vegas Sands Corp. (LVS), Asia is its biggest and most profitable market by far." I know a Chinese gal that runs a breakfast-lunch place and works hard 6 days a week. But she doesn't trust the US stock market and only invests in Chinese stocks, and keeps losing money. She doesn't gamble, just buys stocks her relatives suggest, and keeps thinking Chinese stocks will pay off someday. I get breakfast of one egg, three strips of bacon, two slices of toast and coffee for $2.50, and no tax. -Bill

Your numbers do not stack up. You keep on harping on about it being a waste of gasoline - but it isn't. The net energy gain from solar PV at low latitudes is real 6-7x. Though solar hot water heating is a lot more cost effective. Solar PV might be a waste of money in that the total capital cost can never be exceeded by the value of the electricity generated but that is a different thing entirely. The economics is improving as thinner and thinner films are made to work and mass produced kit enters the market. Early adopters always end up paying over the odds and to kick start the market it makes sense for some subsidies for renewables to help wean people off their standard assumption of dirt cheap gas forever.

No, it definitely is not. The "things" are one in the same. Utilities often contractually equate present kilowatt hours with present dimes. The two are often thus fungible and interchangeable. Money IS energy. Spending money IS spending gasoline. http://www.tinaja.com/glib/pvlect2.pdf -- Many thanks, Don Lancaster voice phone: (928)428-4073 Synergetics 3860 West First Street Box 809 Thatcher, AZ 85552 rss: http://www.tinaja.com/whtnu.xml email: don(a)tinaja.com Please visit my GURU's LAIR web site at http://www.tinaja.com |
