评论：UPDATE - From The Chinese American Professors and Professionals Network (2014 No.31) |

This needs to travel far and wide before November 4th:
The typical U.S. household headed by a person age 65 or older has a net worth 47 times greater than a household headed by someone under 35, according to an analysis of census data released Monday.
They like to refer to us as senior citizens, old fogies, geezers, and in some cases dinosaurs. Some of us are "Baby Boomers" getting ready to retire. Others have been retired for some time. We walk a little slower these days and our eyes and hearing are not what they once were. We worked hard, raised our children, worshiped our God and grown old together.
Yes, we are the ones some refer to as being over the hill, and that is probably true. But before writing us off completely, there are a few things that need to be taken into consideration. In school we studied English, history, math, and science which enabled us to lead America into the technological age. Most of us remember what outhouses were, many of us with firsthand experience. We remember the days of telephone party-lines, 25 cent gasoline, and milk and ice being delivered to our homes. For those of you who don't know what an icebox is, today they are electric and referred to as refrigerators. A few even remember when cars were started with a crank. Yes, we lived those days. We are probably considered old fashioned and out-dated by many. But there are a few things you need to remember before completely writing us off.
We won World War II, fought in Korea and Viet Nam . We can quote The Pledge of Allegiance, and know where to place our hand while doing so. We wore the uniform of our country with pride and lost many friends on the battlefield. We didn't fight for the Socialist States of America ; we fought for the "Land of the Free and the Home of the Brave." We wore different uniforms but carried the same flag. We know the words to the Star Spangled Banner , America , and America the Beautiful by heart, and you may even see some tears running down our cheeks as we sing. We have lived what many of you have only read in history books and we feel no obligation to apologize to anyone for America .
Yes, we are old and slow these days but rest assured, we have at least one good fight left in us. We have loved this country, fought for it, and died for it, and now we are going to save it. It is our country and nobody is going to take it away from us. We took oaths to defend America against all enemies, foreign and domestic, and that is an oath we plan to keep. There are those who want to destroy this land we love but, like our founders, there is no way we are going to remain silent. It was mostly the young people of this nation who elected Obama and the Democratic Congress. You fell for the "Hope and Change" which in reality was nothing but "Hype and Lies."
You youngsters have tasted socialism and seen evil face to face, and have found you don't like it after all. You make a lot of noise, but most are all too interested in their careers or "Climbing the Social Ladder" to be involved in such mundane things as patriotism and voting. Many of those who fell for the "Great Lie" in 2008 are now having buyer's remorse. With all the education we gave you, you didn't have sense enough to see through the lies and instead drank the 'Kool-Aid.' Now you're paying the price and complaining about it. No jobs, lost mortgages, higher taxes, and less freedom. This is what you voted for and this is what you got. We entrusted you with the Torch of Liberty and you traded it for a paycheck and a fancy house.

评论：秋季多起性侵犯发生 圣迭戈州立大学（SDSU）重抓防范教育 |
|
|
今天又看到同类案件发生在同一个圣迭戈一大学校园（SDSU）, 请看消息链接：http://fox5sandiego.com/2014/10/26/sex-assault-reported-near-sdsu
我看后感到非常认同的是下面这则评论："Black and White says: I was on the campus the other night for a concert and noticed all the push button help me boxes around the campus as well as many campus police offices. Good job! However I also noticed a large amount of young women all walking around with their behinds hanging out of their daisy dukes. I mean really hanging out. Does anyone at campus ever talk about provocative attire? Or nobody wants to cross that bridge? Yes I know your burning up the keyboards with “I can wear whatever I want. By all mean do and when you become a victim maybe you’ll rethink how you dress. Be safe。“
我觉得真该从社会舆论方面多对这种现象展开批评，目前很多校园（无论是在美国和中国），有的女同学穿着打扮的观念和追求，有的真的太开放了。- 和我们读书的年代，从中学一直到大学，公共场所女同学该如何体现的观念大相径庭，我们的老师和校方对此也很严格。除非我记错了，初中时候流行裙子，但我都不敢，呵呵。 |

评论：新加坡南洋理工大学陈晓冬研发出新型锂离子电池 急速充电超长待机20年 |
|

开发新型手机发电电池的成果
前言：发电实验样品（已有专利号），能够把环境中的温度转换为电流发电。原始实验达到的指标是：原始实验单片(1 cm2平方厘米，厚3μm微米) 120 mV，2 μA，（后来样品中,曾经出过230μA微安的纪录）.可以带动一个电子跑表，是一个现成成果。本技术在此基础上将输出功率有效提高1000倍以上。使用不受场地、昼夜限制，寿命长、免维护。广泛的应用前景，市场潜力巨大。现阶段可提升到带动钟表和手机。极大优势不愁市场和销售，只愁生产规模无法满足市场需求，以及保持技术领先。
二：发电电池开发领域：
1986年以来，中国物理学者经常观察到把电子二极管的2级连接一个电阻时，其回路中出现反常电流，他们分别在中国设计了热电转换实验，这些实验装置就能把环境温度中的热量连续不断转化成为电能，其中一种实验装置持续工作25年后，输出的电流不衰减。这一种实验首次开创了利用环境温度发电，其中存在着重大机遇。
因为电子管制作的热电转换实验输出功率太小还无法实用，原始实验在半导体上制作：其中有1方形载玻片，作热电转换实验的衬板；铬层c；硅层b；锑层a。热电转换实验是在两块金属板之间夹一层半导体构成的，其中一块金属板是光滑的，而另一块金属板上布满小坑。当小坑的直径非常小时，该器件能输出直流电流、电压，并且可以带动电子跑表。在热电转换实验最新能作到：单片1平方厘米、电压800（mv）、电流4.5（μA），（曾经出过230μA微安的纪录）。它仅仅是一个实验现象，目前小坑的直径为微米量级，积成块能做到1.5伏特，可带动一个电子跑表。如果能将小坑的直径缩小到现在的百分之一,输出的电流就有可能带动家用小型汽车。而这将是一种取之不尽、完全没有污染的新型能源。
三：发电电池运用一项原创性物理发现
我们的研究发现：固体物理性质能够直接把环境温度转化为有用功，关于这个原理的科学证明方法请教上海交通大学物理系傅信镛教授，他提出审评意见：“我认为它在热力学中应该有一席之地。”科学只相信证明，发电实验经过严谨科学证明，这发现的科学原理经过20年验证，对此没有认真调查切忌随意妄作误判。
发电实验样品是一个现成成果。本来四川省作为应用项目上报中国国家部门发改委，请求将其列入中国“国家重大科技创新试点工程”立项，并申请项目专项拨款3000万元开发，当时实验室样品就有望发展成可以在手机上长期使用而不需充电的电池产品，前景广阔。科学经得起检验，中科院的专家召开鉴定会，与参与验证实验的专家认为该实验结果真实可信，理论分析合乎道理，建议有关部门给予大力资助和支持，以尽快使它走向实际应用，建立新工业。最后发改委采信了没有作过发明创造的80多岁老人的主观偏见和随意妄断，致使发改委疑神疑鬼，无端猜疑重大科学实验报告，立项深陷困扰遭遇蒙难。
值得注意的是：发电电池如果不是开发单一温度或者无温差发电，它就不可能具有每年2000亿美元利润和建立世界第一大公司的前景。因为2005年前原始实验无法采用一种新材料，发电实验用这种新材料改造就能够将输出功率有效提高1000倍以上。环境温度是巨大的单一热源而且十分方便。发现这个新的热动力原理突破了单一热源中的热量一直无法开发利用状况，开创了新能源途径和财富源头。qq；2817497177电话；13224081600
四、市场前景分析
电池是更具有爆炸性增长潜力的技术。热电转换实验只是一个原始阶段的实验，虽然实验能够带动一个电子跑表，却只完成了一半，应用前景尚未开拓。由于热电转换实验还存在一种自我增长的性质，一旦改造热电转换实验运用其增长的性质，那么提升起来的输出功率就可以带动钟表、手机，现阶段我们可以制作出样品达到带动钟表、手机的电池运用。市场每年产生大于2000亿美元的利润
1、发电电池是开发环境温度以及单一热源之中的热量发电，能够从取之不尽的环境温度中获取热量持续地转换为电能来带动钟表、手机，并且终身使用根本不需要通过固定电源给它充电，它由硅构成，资源丰富、体积小、免维护、寿命长、无污染、不受昼夜和场地限制，性能可靠，比光伏电池适用面更广。必然以无以伦比的优越性取代现在使用的各种手机充电电池。
2、市场潜力更加诱人：以后将发电电池功率进一步提高后，再多个串联并联，可以构成强大的发电器，如果研究用这种电池带动电动轿车。电动轿车不再需要充电电站和电桩。它由硅构成，它不污染环境，对人体无害，是新的财富源头。
3、传统电池是储蓄化学能量，其中化学反应只能连续使用几天最多1个月，就需要固定电源充电或者报废，寿命短、污染大。发电和蓄电比较起来二者层次差距很大。
4、手机通讯行业作为近年来少有的高成长行业，巨大市场规模仍然在不断增长。目前手机配套市场的年增长率高达20％以上，属于高成长行业。现在全球总的手机持有量大约40亿部，全球每年随手机生产、销售的手机电池就不下15亿块。现在的手机充电电池只能储蓄电能无法与新型手机发电电池的发电优势相比较，有了手机发电电池产品后其它手机充电电池只有淘汰。手机发电电池每块材料成本20元之内（人民币），销售价500—800元。开发全球市场每年接近万亿规模需求，市场每年产生大于2000亿美元的利润。发电电池未来具有的优势竞争力以及发展潜力和空间也可见一斑。
5，具备制作条件后，半年至1年完成小试，2年内投产，半年内收回全部成本。
