In Obama’s God damn America we do truly breathtakingly stupid things and
then keep doing them until we collapse. And then of course we can also add
a healthy mixture of Obama’s crony capitalist fascism:

Investors have followed David Einhorn's every move since he predicted Lehman
Brothers' coming demise in early 2008.
Chasing David Einhorn can be a dangerous investing game. Investors in a tiny

而政府的政策是随时变换的， 就这几年就有几个波浪了。。
如果career based在这个上面，风险太大。
当然，如果你喜欢take risk， 那是另一回事。
另外，biofuel和oil industry不算很近。大石油公司都有研究biofuel的，钱也会有，
但是如果出现

Environmentalists take action against alternative fuels that were supposed

Biofuels in Europe now have more hoops to splash through if they want a tax

least 35 percent (compared to gas and diesel) after production and
transportation emissions are factored in. Th |

Biofuel can be broadly defined as solid, liquid, or gas fuel consisting of,
or derived from biomass. The definition used here is narrower: biofuel is
defined as liquid or gas transportation fuel derived from biomass. Biomass
can also be used directly for heating or power: this is commonly called
biomass fuel: see biomass heating systems. Biofuel is considered an
important means of reducing[citation needed] greenhouse gas emissions and
increasing energy security by providing a viable al |

Biofuels are used for transportation sector but not good for electricity
generation or burning. Biomass may be the sole sustainable primary energy
source for transportation sector. So it is why it is important to develop
better biofuels. (Note: transportation fuels accounts for ~20 % of the total
energy market based on BTU. In the USA, it is about ~30% of total market).

市场完全不能消化现在的产量，为啥，太贵了，卖不出去。没几个厂是全负荷开工的，
好多都是前几年疯的
时候建起来的。
biofuel的问题是价格完全不能和传统fuel比，biofuel的出路只能是寻求更低的成本的
工艺。
在成本降低之前，这些厂只能靠政府资助延续。最后的结局悲观一点，很可能就是被放

process cost and process efficiency. Cost factors include feedstock cost,
conversion yield, utility consumption, product separation, scale-up

Process efficiency mainly depends on theoretical yields and how much
practical yields you can reach at reasonable costs. In fact, fuel quality
is the least important at all. Note: solar energy is not free if you

发帖数: 138 | 39 but in my opinion, the research will be much like waste of money.
It should be clear that oil and gas are plenty (for at least 100 yrs) before
meaningful production is ceased. Fossil fuels will dominate energy (>2/3)
use in the next several generations to come. The most promising energy
source will be nuclear (and 99% of current energy comes from nuclear one way
or another). Renewable energy (mainly hydraulic) will always play a minor
role, and biofuel is even minor compared with its peers, n |

Now, the biofuel has about 11 billion gallons per year (>95% from food

year in 2025 (and food feedstock is about 15 billion). It seems to be a
large number, however, it only accounts for 2.7% of petroleum consumption at
current level (86 MMBOE/day, or 1320 billion gallons equivalent per year).
