("Both natural gas and biogas create emissions when burned, but far less
than coal and oil do. And unlike natural gas, which is pumped from deep
underground, biogas counts as a renewable energy source: it is made from
biological waste that in many cases would otherwise de... 阅读全帖 |

Earlier this year, environmental activist group Greenpeace made waves with a
report taking Apple and other companies to task for not doing enough to
eliminate the use of dirty coal-sourced power at their data centers. Apple
quickly responded at the time to note that Greenpeace had greatly
overestimated the power needs of the company's flagship data center in
Maiden, North Carolina, thereby understating the impact of Apple's solar and
fuel cell power generation occu... 阅读全帖 |

It’s likely not the first thing you think of when you see elephant dung,
but this material turns out to be an excellent source of cellulose for paper
manufacturing in countries where trees are scarce, scientists report. And
in regions with plenty of farm animals such as cows, upcycling manure into
paper products could be a cheap and environmentally sound method to get rid
of this pervasive agricultural waste.

发帖数: 16778 | 9 In my understanding, the drain system in a house should be connected
together.
I mean the drain from kitchen and the drain from toilet or bathroom
should be all merged together into the main drain, which eventually goes to
the sewage.
How can you get the drain water out of the kitchen separately?
You drain system for the kitchen is independant of the one for the toilet?
1,2, you can do this, but not a good idea.
3, you cannot do this, because neighbors will complain about it.

发帖数: 1234 | 11 Wind River也算占据行业垄断地位，在经济危机中业绩还不错，尤其是中国区发展良好
。这个公司被卖真不斥是重磅炸弹.
为什么要卖呢？
winder river的founder, Jerry Fiddler是个牛人，他LP也是founder之一, Jerry近几
年致力于biogas的研究， 我大胆猜测是最近取得重大技术突破，或者是商业化模型已
论证，研究成果需要到了进入生产商品化的阶段，需要大笔投资，所以卖掉即使盈利但
是已经没暴利的wind river.
计算机相关行业已是夕阳之末，牛人们要么拼命扩张，大鱼吃小鱼，要么投身新的泡沫
行业。
我们硅工想多赚点钱，不想就这么老老实实被资本家剥削的，也赶紧四处打探，跻身其

发帖数: 7 | 12 【游戏简介】
在《Agricultural Simulator 2011》游戏中，玩家需要负责起属于自己的一片农
场，打理传统农场主所应尽的一切事务，比如畜牧以及耕种等。经营你农场的产品，然
后扩充机械设备。
这款游戏允许你操作许多不同型号的农业机械。销售你的产品并且投资在更好的设
备。更加强力的机械将帮助你耕种更广阔的农场区域。作为一位努力的农场主，你必须
谨慎投资并最大化作物产量，不可毫无约束，否则你将无法升级你的农场和购买更多的
土地。
本作的黄金版除了游戏本体之外还包含了附加内容“Biogas”。

发帖数: 13203 | 13 日本马桶制造商龙头 TOTO为了要宣传公司订出的TOTO Green Challenge降低厕所50%的
CO2排放量计划，特别打造出一辆搭载TOTO马桶，并使用 biogas沼气(也就是污水沟或
粪便)动力的“Toilet Bike Neo”马桶机车。Toilet Bike Neo马桶机车计划将于10月6
日由 TOTO的九州总厂出发，开始1个月的旅程。在前往终点 东京的一路上，Toilet
Bike Neo马桶机车将停放在不同的定点，向当地居民展现新奇的马桶机车，同时也将介
绍 TOTO提倡的节能减碳计划。
理论上来说，只要驾驶员能固定饮食并顺利排便的话，机车就能获得足够的动力完成挑

his presentation. He compared different energy forms based on heat content
only -- renewable electricity vs biogas (methane, a key component of natural
gas). He knows little about renewable energy but he guide direction of this
research. The reality is low-level persons or cheats dominate academia. |

发帖数: 773 | 16 Most Chinese scientists like using the name of transformative technology for
doing low (no)-tech work. All of key technologies for cellulosic ethanol
are imported from USA. Why? USA cannot make money from it. So, China spent
money on taking risks for them.
欧阳平凯 is working on a mature technology -- anaerobic digestion (> 100
years). This technology is designed to waste treatment not only for energy
generation. Biogas is only plus because natural gas is too cheap. |

发帖数: 744 | 19 在biogas里,CO2和CH4加起来不到100%,实验结果好的,比较接近100%,其他气体象N2,H2,
O2,H2S都很少;结果不好的话,如果有空气进入,比率就比较低了,厌氧过程也会被抑制.
如果你的实验结果远低100%,可能是你的实验过程中有问题,常见的原因就是空气泄露进
入.当然了,无论如何,写paper时应该如实汇报,不可以编造数据.

发帖数: 814 | 21 好奇看了一下他们的网站，我就说两句
首先不是什么新技术。看网上的说明应该是gasification（气化）。简单来说就是在缺
氧（注意是缺氧，不是厌氧）条件下，燃烧部分有机物，这个过程中产生的能量是另一
部分有机物气化，生成一氧化碳（CO）和氢气（H2）。产生的气体叫syngas（煤气）而
不是biogas（沼气）。后者的主要成分是甲烷（CH4）和二氧化碳（CO2）。
煤气大家应该很熟悉吧。以前家里用的煤气罐里面就是这个东西，只不过是加压液化了
的。之所以叫煤气是因为以前通常是用煤来产生煤气。当然这个技术理论上可以用于任
何有机物。
气化后剩下的残余物包括char（焦油）和charcoal（焦炭）。这些个东西能不能做建筑
材料？你要是非说可以是可以的，就好像我说一坨泥巴可以做建筑材料你也会同意吧。
总结一下哈，老技术，新概念，有一定的忽悠成分。
具体能不能赚钱，这个东西在欧洲一些国家是有市场的。为什么？两个方面，一是传统
有机废物处置方法（填埋）价格高，而是政府对renewable energy有补贴。目前在美国
如果没有政府补贴的话，这类项目肯定是亏钱的，因为填埋价格低。国内的话，填... 阅读全帖 |

正如塑料工业对石油的依赖，欧美早就开始了用转基因的土豆来制成高分子材料。。。
， 同时Biogas替代汽车燃油也正方兴未艾。
众所周知，高分子工程材料可以在很多应用中替代钢铁，但不能全部。
鉴于当前几大国际铁矿商，疯狂涨价，其势会对中国的钢铁工业乃至汽车业等造成极大
冲击。
可是，生产钢铁的铁矿石是不是也有替代品? (当然提高转化率，提高钢铁产品的出口
关税是被动办法...) |
