China, Taiwan Agree on More Direct Flights, Shipping, Mail

China and Taiwan agreed on 108 weekly flights that no longer have to go through Hong Kong airspace.

The two sides also agreed to direct shipping links between 63 Chinese ports and 11 Taiwanese ports. The transport links will take effect within 40 days. Direct shipping links can save more than $100 million in costs a year, Zheng Lizhong, the deputy to China’s top Taiwan envoy, said.

China and Taiwan will discuss financial ties in coming months, including allowing Taiwan banks to directly buy stakes in or units of banks and securities brokerages in China, Straits Exchange Foundation’s Vice Chairman Kao Koong-lian said today.

“Chances are high” that the two sides will sign a memorandum of understanding agreeing on “financial ties in the next round of talks in the first half of next year,” he said. Chen has invited his counterpart Chiang to visit China in the first half of 2009 for the next round of talks, Kao said.

Taiwan’s DPP Opposes This

“Even if these economic benefits existed, it is controlled in the hands of China, and the government seems to be prepared to trade off our sovereignty in order to gain these economic benefits,” said DPP Chairwoman Tsai Ing-wen, in a statement issued yesterday.

“Taiwan and China simply are trying to recover the basic communication channels they lost previously, so there is no need to overexpose the sovereignty issue,” Chinese Culture University’s Yang said. “The DPP simply is seeing it as a zero- sum game to meet its own political needs.”

The infrared nanoantennas still need to convert the gathered energy into electricity [seems like a few years away from getting a full cycle worked out, so thermoelectrics are ahead in terms of commercial usage. The 40%improved MIT system/boston college stuff will be out this year. It is based on a variation of already commercialized material]. Plus I do not think nanoantennas are that tough (able to take extreme temperature ranges) substrate plastic. But the metal nanofeatures could be made on tougher material.

However, the nanoantennas are another pathway to capturing and using heat. I think there will be applications where they will be very useful. It is always good to have competing options and possible solutions.

I believe that there is a wave of technology that will allow far higher thermal efficiency. Currently about 33% for power systems (steam for coal, nuclear etc...) Just making high temperature versions can up efficiency to 40-50%.

For vehicles putting electric engines in the wheels can eliminate drive train inefficiency. Getting good thermoelectric mastery could eliminate the combustion engine. Create high temperature generator and directly capture the heat with high efficiency converters to directly power the electric in wheel engines.

I think we could more than double generator efficency from 33% to 70% and triple car efficiency from 20% to 60% by 2020. Then it is question of deployment and rollout. Converting existing installed base.

Maybe those infrared nanoantennas could be made to work for this purpose in the future. The infrared emittance of hot waste steam from the turbine would be pretty high, so a higher efficiency might be obtained.

What do you think?

The immediate new thermoelectric converters ready for widescale use do not work at really high temperatures. They are not that robust. So smaller energy capture can be more immediately applied. (my latest thermoelectric article on the http://nextbigfuture.com/2008/03/thermoelectric-40-improvement-in-cheap_20.html" REL="nofollow">thermoelectric improvement in a cheap material

I think they could find a 8-10% differential for ZT 1.4-2.5 material. That would like making 6-8 nuclear reactors if they could apply it the 104 US reactors or 25-40 if applied to the 435 worldwide reactors. They need to toughen the cheap and widely applicable stuff up beyond 250C.

New nuclear fuel coatings can allow higher temperature operation and thus higher conversion.

The problem is the low temperature of the existing nuclear powerplants turbine outlet temperature. Typically in the 475-500K range, so no 500K delta T there. I doubt more than 100-150 delta T is possible without very high parasitic losses, maybe 15% thermoelectric efficiency with ZT of 10.
