FBI Director Christopher Wray says China is agency's top counterintelligence

CHRISTOPHER WRAY: If I look at our counterintelligence mission overall,
China is our top priority in that space… We've had cases involving
everything from turbine technology in places like upstate New York to corn
seed development in Iowa.

The boat she plans to take, Malizia II, is outfitted with solar panels and
underwater turbines to generate electricity. That should make the entire
trip possible without burning any fossil fuels.
Boris Herrmann, who will skipper the boat, said the voyage would not be the
luxury cruise that a high-tech yacht might conjure in the popular
imagination. The Malizia II is built for speed, not comfort. It has no
kitchen, refrigeration system, air-conditioning or showers. |

Sneaking subs into waters off the west coast — its happened before
By Wayne Madsen
The firing of a submarine-launched ballistic missile by a Chinese Jin-class
submarine off the coast of southern California lastMonday at the height of
evening rush hour in Los Angeles was not the first time the U.S. Navy's anti
-submarine warfare sensors in the Pacific have failed.

By Yoichi Shimatsu

Confused and often conflicting reports out of Fukushima 1 nuclear plant
cannot be solely the result of tsunami-caused breakdowns, bungling or
miscommunication. Inexplicable delays and half-baked explanations from Tokyo
Electric Power Company (TEPCO) and the Ministry of Economy, Trade and
Industry (METI) seem to be driven by some unspoken factor.

出力来驱动增压器，再将高密度空气送入汽缸内以提高引擎的输出功率。
涡轮增压则是利用引擎的废气排放来驱动压缩机。最早的增压器全部都是机械增压，在
刚发明时被称超级增压器(Supercharge)，后来涡轮增压发明之后为了区隔两者。起初
涡轮增压器被称为Turbo Supercharger，机械增压则被称为Mechanical Supercharger
，久而久之，两者就分别被简化为Turbocharger与Supercharger了。
涡轮增压原理利用引擎运转时所排出来的废气,用废气来转动涡轮增压器中的排气侧转
子,而排气侧转子与进气侧转子(Compressor)是同轴异室,当Turbine转子达到一定转速
时(约12000rpm左右)它带动另一侧的Compressor,使Compressor转子引进外来的新鲜空
气,经过压缩倒入进气歧管内,因此Turbo车的进气是非自然方式,是经过"吸进来,再压缩
"所以空气压力是大于大气压力的。涡轮增压由于是超高转速地运转轴承,随之而来的高

发帖数: 1634 | 16 看见一帮同学们十分情绪的眺望美好未来，实在是看不下去了，列举几点：
能源角度：
1）电能绝大多数也是从化学能过来的
电厂发电效率能到45～50%，gas turbine发电的能接近60%，但是发电峰值峰谷的调节
是个大问题，智能电网这几年很火也是有一定原因的
2）现今的内燃机效率有很大的提升，未来10年内将会有更大的发展，尤其是柴油机。
45～50%效率的内燃机完全可期待
环境角度：
1）电能主要还是传统化学能源，烧煤和烧天然气（甲烷为主），CO2的排放一样是个大
问题，
新能源是好，但是环境问题一样值得考量，水能例如三峡大坝
，风能极其不稳定，核能核废料处理困难，太阳能能量密度太低
2）电池的生产和废电池的处理都带来极大的环境污染，以前常说废电池要集中处理，
一个5号电池就能污染一大片，现在没人care了，就知道tesla好，tesla棒，tesla顶呱呱
经济角度
1）电价和油价的竞争。相对来说电价是便宜，但是不要忘了，现阶段电价已经开始分

你看到的CVT是家用带torque converter，动力损失大但耐久性好，启动的时候液力带
动turbin来transfer动力
运动车用的DCT和manual一样，它有个start clutch，也就是说启动一瞬间是硬连接，
当然快，问题是磨损大，维护高。 VW的DSG被喷成大傻瓜别忘了
如果你给DCT装个TQ，它也会变肉，你给CVT装clutch，它照样能飞，只是设计上
