Residential electricity rates

Residential electricity rates are difficult to understand. It takes a PhD to read a utility bill. Rates are based on a tier system, similar to a progressive tax system's tax bracket. The more juice you use, the higher rates will be. There is a baseline usage whose rate is lowest.

For a baseline usage of 12.1 kWh per day and PG&E's Electric Schedule E-1 published are used in the following plots. .

Rate per kWh in tabular form



Monthly payment of electricity bill.


Cost breakdown
Now that you have paid your electricity bill, how does that cost breakdown? For the Tier 1 rate, the power plants get about 5 cents out of a total 12 cents. PG&E which is responsible for distribution and transmission gets about 5 cents. The rest of 2 cents pay for all kinds of fees.

Another matrix example

This next example was one I tried to create using WPMathPub but had trouble because it wasn’t very intuitive (see WPMathPub article).

[53cos26701-2sin5]

Now, that was much easier compared to WPMathPub! This is the code I used for the above ASCIIMathML:

[(5, 3, cos 2), (6, 7, 0), (1,-2, sin 5)]

In ASCIIMathML, it can be rendered easily like this:

3∫x2 dx+5∫x dx+9∫ dx


This is some example code:

\begin{gra ph}width=400; height=300; xmin=-6.3; xmax=6.3;
xscl=1; plot(3cos(x^2)) \end{graph}

Here is the resulting graph. Move your mouse cursor over the graph – it tells you the x- and y-coordinates of the cursor position.

1 2 3 4 5 6 -1 -2 -3 -4 -5 -6 1 2 3 4 -1 -2 -3 -4
Update
width=400; height=300; xmin=-6.3; xmax=6.3;xscl=1; axes(); plot(3cos(x^2))

I’ll do a separate article soon about the graphing capabilities of ASCIIMathML.

光伏行业“规则破坏者”

在当前中国光伏发电行业,一直有“南尚德,北英利”之说。与“技术派”施正荣相比,营销起家的苗连生被誉为“成本杀手”。在2009年广受关注的敦煌电站 招标项目中,英利所提供的组件报价是0.69元/度,远低于业内超过2元/度的平均成本,为此苗连生几乎挨了半年的骂,被斥为“规则破坏者”。

1.09元/千瓦时

该项目已由江苏百世德太阳能科技公司(以下简称百世德)、中广核能源开发有限责任公司(以下简称中广核能源公司)和比利时Enfinity公司三家组成的联合体,以1.09元/千瓦时的价格竞标成功。

工业品出厂价普降 钢铁石化品跌幅居前

工业品出厂价普降 钢铁石化品跌幅居前

统计局:工业品出厂价普降 钢铁石化品跌幅居前--经济频道--人民网
人民网北京2010/6月17日专电 (记者扎西)17日,国家统计局发布部分重点企业主要工业品 出厂价格。数据显示,5月下旬至本月上旬,相应产品价格整体下滑,其中钢铁制品及石化产品跌幅较大。

  因受国家调控房地产市场影响,加 上经济增长放缓,汽车产量、房屋开工率等指标均有显著下滑,使得下游钢材、有色需求锐减,引发价格滑坡。同期,国际油价出现大幅回落,发改委于5月末下调 国内成品油零售价220-230元/吨,国内石化产品价格随之进一步下行。

  数据显示,5月21日至6月10日,国内大中型普钢环比下 滑3.6%-13.1%,小型线材下滑4.4%-7.3%。其中各类螺纹钢价格在 3532.4-3760.8元/吨,环比下滑3.6%-7.3%;同期 品位在56%以上的铁矿石报价为580.4元/吨,环比下滑6.5%。同期,国内原油出厂价为3747.1元/吨,环比下滑4%。成品油方面,93#汽 油、97#汽油、-10#柴油、0#柴油出厂价分别为6404.5元 /吨、6846.9元/吨、6035.2元/吨和5464.8元/吨,环比分别下滑 2.7%、2.5%、2.7%和3%。乙烯出厂价为7860.9元 /吨,环比下跌9%。

  有色金属方面,铜价42692.3元/吨, 环比下滑6.5%;铝锭11421.5元/吨,环比下滑6.2%。同期,各型号水泥出厂价则在248.9-378元/吨不等,环比下滑 1.8%-2.1%。国内无烟煤价格为452.7元/吨,环比涨1.1%。

Deepwater Horizon oil spill, a death by thousand knives, winners and losers




Deepwater Horizon oil spill 4202010


light Louisiana crude oil shows the color of orange to red. I suspect the black part of crude was lost to solidification under high pressure under sea.
How bad is the situations

The gusher, now estimated by the quasi-official Flow Rate Technical Group to be flowing at 20,000 to 40,000 barrels per day URL
http://en.wikipedia.org/wiki/Deepwater_Horizon_oil_spill Accessed Monday, June 14, 2010
At 30,000 barrels/day the amount of = 44 kiloton of TNT/day

Place Date Yield of the explosion
Hiroshima A-bomb 广岛 08/06/1945 15 kilotons TNT
Nagasaki A-bomb 长崎 08/09/1945 21 kilotons TNT
Deepwater Horizon Rig 04/20/2010 44 kilotons TNT/per day^a

^a
leak based on 30,000 barrels/day . 1 Barrel = 42 US gallons = 5,800,000 Btu .

What is going to happen?
  1. the effect of oil contamination is long term. It will take more than 100 years for the nature to digest the crude. It takes millions years for the crude to form. The crude is kinetically stable, and thermodynamically unstable with chemist's parlance. Most of them are fused benzene rings.
  2. The crude will coagulate into balls with diameters ranging from millimeters to inches. And those tar balls will settle into holes of beaches.
  3. Those chemicals are toxic, carcinogin. They are water insoluble and soluble in fat. Therefore no more fish oils from Gulf.
  4. Fish will die. Fish gill will be neutralized by the radicals generated from the bio-degradation of crude oil, rendering fish cannot get oxygen from water.
  5. the damage is in the trillions US dollars. Therefore, BP has to file bankruptcy, and sell to a third party, such as Exxon Mobil or PetroChina. Sale to PetroChina is politically dead since last time CNOOC failed to buy Unocal because US Congress was vehemently against it. When the news announces, Exxon Mobil buys BP US interests, Exxon Mobil stock will dive. A buying opportunity for XOM for average investors?
  6. The current $3/gallon US gasoline at 06/14/2010 is too low, it doesn't cover the risk factor of crude production.
  7. higher cost for gasoline. Bad news for American drivers. Exxon and Saudis will laugh all the way to the bank.
Winners
Saudis >
Exxon.

Losers
Environment > car drivers > Obama.

中国特色的脑筋急转弯:

刚上大学,我们怀着憧憬看了《奋斗》,当我们踟躇的时候,我们看了《我的青春谁做主》,就当我们即将豁然开朗的时候,一部《蜗居》把我们全拍死了。绝望中,我们看了《2012》,顿时淡定了。买什么房子啊,早晚要塌的!

紧急通知:H1N1防病要诀:不接吻不拥抱,男女见面光傻笑;情要忍,意须消,媚眼可以使劲抛!去年这个时候我们在外面躲地震,今年这个时候我们在家里躲流感。去年这个时候没事别呆在家里,今年这个时候没事别呆在外面。去年猪是坚强的,今年猪是疯狂的。

没有房地产就没有新中国,没有房地产就没有新中国。房地产,它辛劳占耕地;房地产,它一心谋暴利。房地产 它忽悠就能活;房地产 它一心救中国 它指给了富豪圈钱的门路,它引导政府走向豪奢。它坚持了疯涨八年多,它改善了官员的生活;它构建了升官GDP,它收取了税费好处多。

人在江湖,身不由己;人在婚姻,爱不由己;人在官场,话不由己;人在单位,事不由己;人在世上,命不由己;人生无奈,有何归己?享受生活,善待自己。

学士上面是硕士,硕士上面是博士,博士上面是博士后,博士后上面呢?如果你够勇敢再读两年是勇士,再读五年是壮士,再读七年是烈士,烈士以后呢?国家会推出圣斗士,读满两年是青铜的,5年是白银的,7年是黄金的。

朋友分很多种:有些人真的是一辈子的朋友,有的不过是一杯子的朋友,当然,还有一被子的朋友。

我有个60岁的朋友,他估计能够活到90岁,是正常的直线折旧。但是后来,他请了一个小保姆,两年后就死了,这就是加速折旧。

Iron, a new life in power lithium ion battery

Iron is critical in human life both as a basic material, and as the oxygen transporter in the blood. The term of iron age is used to take the place of bronze age. Iron age tells how important the iron, then later steel is for the human civilization.

Oddily enough, there are 2 to 6 grams of iron in adults, enough to make a couple of nails. In biology, iron is credited with binding site for oxygen molecule in the red cell. Without iron, no life will be possible.

The strangest part is that iron finds new application in the lithium ion rechargeable battery. Lithium ion batteries are widely used in portable electronics because of their low weight, high energy density. An iron containing material is discovered to be one of the best for lithium ion battery. People dub the thus made batteries as LIFE batteries. Li and Fe are chemistry symbol for the elements of lithium and iron respectively.

The principle for iron in blood to transport oxygen molecules is the same as in the latest lithium ion battery. Is that amazing? The god, or nature picked iron to be used in blood, and now LIBs have iron in it which has the chemistry. The chemistry can be summarized as Fe3+/Fe2+ redox couple.

Iron is also one of the most stable nuclei in all elements. ie, either fusion of fission, will mostly likely lead to iron.

Energy units

http://bioenergy.ornl.gov/papers/misc/energy_conv.html

This is a quick-reference list of conversion factors used by the Bioenergy Feedstock Development Programs at ORNL. It was compiled from a wide range of sources, and is designed to be concise and convenient rather than all-inclusive. Most conversion factors and data are given to only 3 significant figures. Users are encouraged to consult other original sources for independent verification of these numbers. The following are links to Web sites we have found useful (many universities worldwide maintain good guides and conversion calculator pages):

Energy contents are expressed here as Lower Heating Value (LHV) unless otherwise stated (this is closest to the actual energy yield in most cases). Higher Heating Value (HHV, including condensation of combustion products) is greater by between 5% (in the case of coal) and 10% (for natural gas), depending mainly on the hydrogen content of the fuel. For most biomass feedstocks this difference appears to be 6-7%. The appropriateness of using LHV or HHV when comparing fuels, calculating thermal efficiencies, etc. really depends upon the application. For stationary combustion where exhaust gases are cooled before discharging (e.g. power stations), HHV is more appropriate. Where no attempt is made to extract useful work from hot exhaust gases (e.g. motor vehicles), the LHV is more suitable. In practice, many European publications report LHV, whereas North American publications use HHV.


Energy units

  • 1.0 liter = 0.264 US gallon = 0.220 imperial gallon
  • 1.0 US bushel = 0.0352 m3 = 0.97 UK bushel = 56 lb, 25 kg (corn or sorghum) = 60 lb, 27 kg (wheat or soybeans) = 40 lb, 18 kg (barley)

Areas and crop yields

  • 1.0 hectare = 10,000 m2 (an area 100 m x 100 m, or 328 x 328 ft) = 2.47 acres
  • 1.0 km2 = 100 hectares = 247 acres
  • 1.0 acre = 0.405 hectares
  • 1.0 US ton/acre = 2.24 t/ha
  • 1 metric tonne/hectare = 0.446 ton/acre
  • 100 g/m2 = 1.0 tonne/hectare = 892 lb/acre
    • for example, a "target" bioenergy crop yield might be: 5.0 US tons/acre (10,000 lb/acre) = 11.2 tonnes/hectare (1120 g/m2)

Biomass energy

  • Cord: a stack of wood comprising 128 cubic feet (3.62 m3); standard dimensions are 4 x 4 x 8 feet, including air space and bark. One cord contains approx. 1.2 U.S. tons (oven-dry) = 2400 pounds = 1089 kg

    • biodiesel density (average) = 0.88 g/ml ( = metric tonnes/m3)

Fossil fuels

  • Barrel of oil equivalent (boe) = approx. 6.1 GJ (5.8 million Btu), equivalent to 1,700 kWh. "Petroleum barrel" is a liquid measure equal to 42 U.S. gallons (35 Imperial gallons or 159 liters); about 7.2 barrels oil are equivalent to one tonne of oil (metric) = 42-45 GJ.
  • Gasoline: US gallon = 115,000 Btu = 121 MJ = 32 MJ/liter (LHV). HHV = 125,000 Btu/gallon = 132 MJ/gallon = 35 MJ/liter

几家欢喜几家愁 盘点嫁给老外的中国女运动员

几家欢喜几家愁 盘点嫁给老外的中国女运动员(图)

婚姻和国籍无关,尤其是经常参加国际大赛的女运动员,会因为和男运动员有着同样的爱好和互相的羡慕,而情不自禁的从喜欢到爱,于是就有了“执子之手,与子偕老;死生契阔,与子相悦。”纵观那些嫁给老外的中国女运动员的婚姻,有喜有忧,令人感慨万千。

资料图片:诸宸与穆罕默德

一、诸宸(中国)与穆罕默德(卡塔尔)

1994 年,16岁的诸宸参加马来西亚亚洲青年国际象棋锦标赛,她连挑数位男子国际大师,第5轮却输给一位叫穆罕默德的卡塔尔小伙子。那年9月,诸宸到巴西马丁霍 斯小城参加世青赛,穆罕默德居然把手表典当出去坐飞机跟到那里。此后,诸宸到哪里比赛,穆罕默德就跟到哪里,他鼓励她,安慰她,像个大男人一样保护她。在 卡塔尔婆家,诸宸享受许多“豁免”待遇,她可以不穿长袍不戴头巾,可以不干家务四处奔忙。

罕 默德在乎诸宸的感受,没有大男子主义,有什么事情都要夫妻协商。为了博得诸宸父母的喜欢,穆罕默德每次来中国前都把胡子剃得干干净净,等回到卡塔尔前再把 胡子蓄起来。这对具有皇室血统的“卡塔尔20世纪最杰出运动员”穆罕默德很不容易。2006年的亚运会,诸宸代表卡塔尔参赛了,这受到了某些人的非议,其 实诸宸已经为中国付出了很多,两人于2000年结婚,但诸宸一直代表中国参赛,她的所有世界冠军头衔,都是婚后获得的,而具有皇室血统的穆罕默德更是被评 为卡塔尔20世纪最杰出运动员。

二、高敏(中国)与陈志刚(加拿大)

巴塞罗那奥运会后,高敏退役,1995年与著名体育评论员苏东结婚,次 年儿子苏超出生。1996年,高敏与苏东离婚。1997年,高敏在加拿大的一次华人聚会中认识陈志刚,并最终走进婚姻的殿堂。高敏从小就有个梦想,就是拥 有一座漂亮的跳水馆,她带着自己的孩子们在家里练习跳水。没过多久,陈志刚把高敏带到一座新落成的漂亮的跳水馆前,说:“这是属于你的。不过,你什么时候 给我生个孩子,那样就美梦成真了。”

高敏仿佛活在童话里,她和陈志刚结婚了。高敏很快又生了一个儿子。让她高兴的是,无论是前夫苏东与陈志刚,还是两个孩子之间,关系都十分融洽,就像一家人一样。

三、焦志敏(中国)与安宰亨(韩国)

焦志敏与安宰亨认识于在1984年的巴基斯坦亚锦赛,1985 年,安宰亨拜托来韩国打比赛的耿丽娟给焦志敏带去了第一份礼物,从此,安宰亨与焦志敏开始礼尚往来。1989年,退役后的焦志敏自费到瑞典去留学。正在服 兵役的安宰亨在体育部长官的疏通下获准赴瑞典向焦志敏求婚,她们在韩国驻瑞使馆注册结婚。她们回到韩国时:汉城金浦机场将一个通道专门留给他们,电视台对 婚礼进行现场直播,警察整齐地站成一列,各路长官、会长的夫人和韩国乒坛名将手捧鲜花等在通道两旁。出了机场,警车开道护送。参加婚礼的嘉宾都是韩国各界 要员。

四、张山(中国)与巴恩斯(澳大利亚)

2004年11月7日,36岁的1992年巴塞罗那奥运会射击 冠军张山与澳大利亚裁判巴恩斯在成都结婚,伴娘是巴恩斯的两个女儿爱玛和丽娜。张山的朋友说:“这么老的姑娘终于嫁出去了,我们的心病也除掉了。”巴恩斯 幸福地说:“我追张山10年了,能倒在她的枪口下,真是无比陶醉啊。”张山于1993年在德国射击比赛,两人相识,并互有好感,但1995年后,张山再也 没有在国际大赛中碰到巴恩斯。直到2000年悉尼奥运会再相遇时巴恩斯已是一名裁判。他当运动员时,曾三度入选澳国家射击队,但没有在世界大赛上有所建 树。

原来1995年之后,巴恩斯经商去了,他曾结婚并有两个女儿, 其后离异。此后每有张山比赛,巴恩斯就向国际射击联合会申请裁判,两人没有道破关系,但都明了彼此的心思。与张山结婚后,巴恩斯想在中国扎根。他爱吃川 菜,还擅长厨艺,是张山的主心骨,也是张山一家人的开心果。他们现住在成都。

五、陈露(中国)与丹尼斯(俄罗斯)

丹尼斯知道陈露是在1988年的莫斯科新闻杯,当时陈露12 岁,但陈露并不知道,她认识丹尼斯是1992年后同在美国参加世界明星巡回表演,在一次巡回演出的大巴上,陈露拿出一块薄荷糖并问周围的人要不要,没人作 声,她便把糖放进自己嘴里,这时丹尼斯开口了:我要。由于大家已经很熟了,我就张开嘴,开玩笑说:我已经放在嘴里了。没想到丹尼斯竟当众回应:那我也要! 结果,当着全车人的面,在大家善意的哄笑中,丹尼斯吻了她。但当陈露已芳心萌动时,丹尼斯却没了下文,甚至在陈露刻意创造独处机会时,丹尼斯更多的也只是 “嘿嘿”赔笑,关于感情却只字不提。于是在一次巡回演出前陈露将他约到酒店的咖啡厅,两人坦诚相对,陈露消除了丹尼斯的顾忌,于是恋爱关系确定了下来。 2004年,华润集团在深圳开的万象城内办了一个国际标准滑冰场,丹尼斯决定跟陈露一起到中国,并向她求婚。2005年7月8日,陈露将和丹尼斯在深圳完 婚。

六、小山智丽(中国)与小山英之(日本)

1989年,何智丽移居日本,同小山英之结婚,改名小山智丽。 很少有中国人愿意提及这个名字,虽然乒乓球队对她有些不公,她的出走也是有些迫不得已。但5年后,小山智丽在广岛亚运会上战胜邓亚萍后,竟然当场喊出了 “哟西”,这确实让中国观众受不了,毕竟连真正日本血统的球员也没有那样喊过。在一次世界级的大赛上,在和中国乒乓球国家队队员比赛之前,她接受记者采访 时,居然说:“我一定会打败中国人!”由此可知,小山智丽的仇恨已经走火入魔,她嫁给小山英之,只怕除了成功,也有对报复的成份。1998年,小山智丽与 小山英之正式宣布离婚,此后她就很少出现在国际赛场上,据圈内人士透露,小山智丽因为公开与小山的婚姻破裂一事引起日本乒协的不满,相信是被日本乒协封 杀。
