Bad Fuel From Pilot Flying J Reportedly Disables Trucks
7
Trucks were experiencing mechanical issues and breakdowns after fueling up
at a Pilot Flying J travel center. At least four trucks couldn’t even make
it off the lot after filling up and other drivers were complaining that
their vehicles were running poorly.
The Pilot Flying J location with the issue was the Von Ormy station on I-35
in Texas. The problem was brought to the attention of the general manager by
a driver who was having an issu... 阅读全帖

但是看起来在欧洲,柴油更popular。而且自己在家就可以生产biodiesel.
Unlike any other fuel for modern engines, biodiesel can be made at home
without investing heavily in special equipment or earning a degree in
chemistry.

哦,但楼主没说alternative energy是哪种啊,
而且他把 biodiesel单列在第一选项里了。
无论如何,做热力学和能源还算不错吧。但是我觉得biodiesel前景比较一般,
做博士课题可以试试,但对MS用处不太大。

来自主题: Military版 - fuck! EPA allows 15% ethanol in gasoline
it is a rip-off for average Americans.
A gallon of ethanol gives about 77 KBTU, and require 35KBTU, and thus net
energy is 42 KBTU.
A gallon of gasoline gives about 125 KBTU and requires about 15 KBTU, and
thus net energy is 110 KBTU, more than 2.5 times higher than ethanol.
Ethanol is about $2.02 /gal (after 0.51/gal of tax-payer money subsidy) in
2008 (the credit was reduced to 0.45/gal in 2009), and gasoline is $2.85/gal

What’s Actually In Instant Ramen
There’s a LOT of sodium. (Photo: Tumblr/kiddwelldontcare)
Odds are, you’ve eaten instant ramen noodles at some point in your life.
Maybe you were in college or trying to save money. Or maybe you think they
just taste really good. Whatever the reason, this five-minute meal has been
a hit with budget-friendly consumers for years.

看来大家对省油及其着迷。我的理解,最好的省油方法,是弄一辆可以用biodiesel的柴
油车。然后去周围收购废的油炸菜油,自己在家里炼。网上有大把教你怎么炼油的。
http://journeytoforever.org/biodiesel_make.html#2svo
我去参观过,设备占地大概150feet左右,在车库的一角就可以开干。链接里的和我看
到的设备挺像。里面有个人问,可不可以利用太阳能来加热——这个idea好啊:)
http://www.youtube.com/watch?v=qzFEurB3ZmY
顺便,还有一个方法,就是直接用废油,缺点是对操作要求比较高,要预热车啥的。
关于价格,我网上看了一眼,废油回收$0.75 Per Gallon,我们这个鬼地方的 Diesel
大概要$3.8-$4.1 per gallon。照这个价格,什么六七八糟都加上,炼出来的油成本
最多也就$2 per gallon,所以肯定能省40-50%的油费。

搞错了,是2K启动(如果猛踩一脚的话),如果慢慢踩的话目测是2K3启动。。。放水
,就是开一段时间油箱会积水,可能是柴油吸湿性比较强,也可能biodiesel里的氢含
量较高,所以定期要放水。我的手册建议3年/30K迈换油滤的时候放。你的不用么?
