昨天感觉自己的状态不错。Cycling Class,使用 Tacx trainer 系统。
完成6组 4分钟的interval(3分钟骑,1分钟recovery). 250watts, 270w,,290w,300w,
310w,320watts. 我没敢试试330, 怕抽筋和恐怖的170的心跳。
320watts 时候心跳是165(这就是我自行车的LT). 相信到4月份, 我能达到350 watts
,心跳170的LT。
如果是1分钟骑,3分钟recovery, 上周我380 watts 的心跳是157. 那么到4月初,400
watts应该心跳也在157或者更少。
与2011年11月18日相比,大腿肌肉耐力明显提高。昨天晚上离开熟悉的自行车店,气温
是零下20.
大脑中还是夏天许多人聚集在这里准备group riding 的场面。 25年前,我打球练球,

The per watt cost we are talking about is module price divided by

不需要绝对准确测量,相对比较就可以。一个手机的antenna的发射功率应该是100w,
一个手机基站的发射功率取决于上面antenna的多少。对外面的影响取决于塔的高度及
周围的环境。所以距离是个很大影响因素。我侧过一个手机塔400外的地方读数为0.02-
0.05微瓦/平方厘米。家里的router5米以内的读数是0.07-0.2微瓦/平方厘米。贴着
router的地方读数更高。我更有无聊的拿着仪器去曼哈顿,基本背景读数就是0.03-0.
04,走过的有Madion Ave, Park Ave.如果到有看得见天线的地方就更强。
其实电视塔的发射更强,可是不是很多人愿意买如明珠塔,cn tower旁有view的房子?
关键手机塔,高压线塔太难看。这种手机天线如果在大城市会很密集的,如果因为这个
不买,就没地方住了。可以用antenna search .com 去看看。但是话说回来,如果因为

昨天上coach D cycling class. 收到一张期待很久的名片: calf(小腿) 抽筋。
当时心跳才150, 功率是290 watts. 我以为我还能再上两个4分钟的interval, 310
watts 和330 watts.边上一个girl 也搞到300 watts.
这是我骑车第一次抽筋。原因很复杂。 直接原因是早上7 miles group running.
一个月前坐 spin scan, 我也push 到 290 watts,心跳都到了170. 当时是马拉松后的
recovery.
虽然冬天的base training, 我都是easy riding, 但是3月份要开始搞强度训练。
如果现在不开始力量训练, 这个强度会打折的。从下周开始系统的力量练习喽。

分析师认为,加拿大元走势与原油价格之间的联系可谓复杂而多变,但作为“石油货币”,加元才不过刚刚起步,因此,随著未来数年加拿大石油产量的逐步扩大,加元与原油价格之间的联系可能将会加强。
RBC Capital Markets驻多伦多资深外汇策略师David Watt在近期的一份报告中指出,不要忘了,加元充当“石油货币”的年头仍然很短。他在报告中写道,加拿大的贸易活动、贸易环境以及加元都将从能源市场的前景中受益。
十大工业国(G10)中只有两个石油净出口国,一个是挪威,另一个就是加拿大。因此,市场普遍把加元视作走势与原油期货大体一致的“石油货币”。
不过实际情况要复杂得多。尽管加元和原油期货不乏步调一致的表现,但有时二者也会走出互不相干的独立行情。Brown Brothers Harriman的一份报告显示,近几周来这种同步性一直不明显。该机构称,自2月15日以来,油价已经飙升了约25%,而加元尽小幅上扬了不到2%。
加元走势向来容易受到围绕全球经济增长的各种担忧的影响,这反映了加拿大经济开放和以贸易为导向的特点。这也意味著,一旦市场认为油价高企预示著全球经济增速放缓,油价因素就可能令加元... 阅读全帖

As zazen pointed out, you can not compare coal and solar installation cost
like that
1. Balance of system cost in solar. Total system cost still at least 3-4 per
watt even
When module price came down a lot ( that 1.3 per watt module is about right
and
Will go lower
2. Total energy output a year at solar is much lower. Number of watt
installed is
Peak output of the module. Even in sunny places like California, average

Is like 6 hours a day. If the solar system generates 20% watt x 365

world performance. If you have sufficient space on your roof to accomodate
lower efficiency solar modules then there is no difference in energy
production. A 300 watt high efficiency solar module like SunPower puts out
nearly the same 300 watts as a 300 watt lower efficiency module. The only
difference is the physical size of the module and of course price. So if you
have sufficient roof space, why on Earth would you pay Su... 阅读全帖

When the presumptive No. 1 overall draft pick opts to go back to school, it
can really alter the draft process. As I detailed here, when Stanford QB
Andrew Luck made that decision, dominos fell. And in over 30 years of
evaluating talent, many of them for ESPN, this year sticks out as one that
could have a lot of movement throughout the process leading to the draft.
But it's time to get going.
As it is every year, the mock draft is a blend of my evaluations, hundreds
of conversations with people ... 阅读全帖

地球上缺少氧气,沙尘暴,这属于行星内部矛盾,好比是天灾。其实这种级别的小灾历
史上也没少有,这种问题都解决不了,说明地球的文明还属于单行星文明。
单行星文明之上是行星际文明,此类文明可以在太阳系内纵横驰骋,改造火星,移民木
星土星的卫星不在话下。但是碰上比如太阳变成红巨星这样的灾难,行星际文明就
HANDLE不了了。
行星际文明之上是恒星级文明,此类文明穿梭于恒星之间,可以在数光年之外的另一个
恒星系建立殖民地。
而interstellsar属于单行星文明的科技水平,却想用恒星级文明的方法来解决问题,
说个不好听的话就是地下室的命操中南海的心。
1964年由苏联天文学家尼古拉·卡尔达肖夫首先提出一個文明所能夠利用的能源总量来
标度一个文明的发展程度。这就是所谓的卡尔达肖夫指数。 按照这个分类,人类连1类
文明都达不到。

Who's calling?" was the answer to the telephone.
"Watt."
"What is your name, please?"
"Watt's my name."
"That's what I asked you. What's your name?"
"That's what I told you. Watt's my name."
A long pause, and then from Watt, "Is this James Brown?"
"No, this is Knott."
"Please tell me your name."
"Will Knott."
Whereupon they both hung up.

'Artificial life' breakthrough announced by scientists
By Victoria Gill Science reporter, BBC News 20 May 2010
Scientists in the US have succeeded in developing the first living cell to
be controlled entirely by synthetic DNA.
The researchers constructed a bacterium's "genetic software" and
transplanted it into a host cell.
The resulting microbe then looked and behaved like the species "dictated" by
the synthetic DNA.
The advance, published in Science, ... 阅读全帖

老铁车子有power meter 吗?
我现在越来越依赖它了。我的腿对watts 感觉也越来越灵敏。
我一般控制在 150 -200 watts。
下坡拼命蹬,上坡慢慢摇。换挡非常频繁。39/53 大小chain 换的也很频繁。
主要是 IM Madison 几乎没有平路。不是上就是下。
如果53 chain, 160 watts, 65 RPM, 速度是 20 mph, 我就会非常乐意保持这个状态。
如果 39 chain, 160 watts, 60 RPM, 速度是10 mph, 我也接受。
