球员工会揭秘密 曝斯特恩收入仅次于科比 - NBA新闻
谈判再次破裂之后，斯特恩对工会的态度颇为不满，并说出了"我不认为劳方会积极地推动谈判的进展"的牢骚话，这引起了美国媒体的强烈不满，并将炮口对准了这位NBA的掌门人。
美国媒体表示，NBA球员们的工资基本上都被媒体公开了，但是总裁斯特恩的工资却是一个秘密，这很神奇。据美国篮球专家猜测，斯特恩的工资大约在每年2000万到2300万美元之间，但是没有人能够确认。雅虎专家阿尔德里奇称，这是个非常敏感的话题，很奇怪，球员工会从来没有勇气去揭露斯特恩的薪水之谜，甚至多数球队老板也不知道。一位球队老板称，只有三个或更少的人知道这个数字。
这个工资是什么概念呢？如果斯特恩的工资是2300万美元的话，那么他的薪水在NBA中仅次于一个人，这个人就是洛杉矶湖人队的超级巨星科比。2011-12赛季，全联盟只有科比一人年薪超过2500万美元(2524.4万)，其余多达400多位NBA球员的薪酬都不如斯特恩。下赛季薪酬分列第二、第三和第四位的分别是拉沙德·刘易斯、蒂姆·邓肯和凯文·加内特，但是他们的薪酬距离斯特恩的2300万年薪仍有差距，其他球员就更不用说了。不上场打球的斯特恩领着这么高的年薪，却要求NBA球员集体降薪，这没有说服力。一位NBA球员直言不讳："要想降我们的薪酬，总裁自己请先带个头。"

Intel acquisition points to cloud networking trends Electronics News
INTEL will acquire Fulcrum Microsystems, a fabless semiconductor firm which designs Ethernet switch silicon for data centre network providers.
According to Intel, this move gels with its current strategy, which is to transform from a server technology company to a comprehensive data centre provider which offers computing, storage and networking building blocks.
Intel says Fulcrum Microsystems’ switch silicon, is recognized for its high performance and low latency.
The products from Fulcrum will complement Intel’s processors and Ethernet controllers, resulting in new levels of performance and energy efficiency, boosting the economy of cloud services.
The move by Intel fits into the trend which is seeing very fast growth for 10 Gigabit Ethernet networks, especially for data centres. Fulcrum Microsystems designs integrated, standards-based 10GbE and 40 Gigabit Ethernet (40GbE) switch silicon that have low latency and workload balancing capabilities while helping provide superior network speeds.
This will help cater to increasing demand for data, supporting the continuing evolution of cloud architectures and enterprise converged networks.
Intel says cloud computing is driving the convergence of server, storage and network technologies and solutions based around Intel Xeon processor solutions. The acquisition will fulfil an important component in Intel’s strategy to deliver comprehensive data centre building blocks, from server processors and technologies to storage and networking.

Mobile recycling fails Electronics News
Two recent reports by the mobile phone industry and a survey conducted by the Total Environment Centre revealed the 'Mobile Muster' scheme as seriously flawed. The industry has achieved a paltry 3% recovery rate and, in the meantime, a mountain of toxic mobiles is waiting to be dumped, Total Environment Centre said."After seven years in the game, all the industry can claim is a pathetic 3% recycling rate, despite collecting a levy on every new phone sold. Mobile Muster is all spin and no substance,” said Jeff Angel, director of the Total Environment Centre."The Australian Mobile Telecommunications Association (AMTA) in two reports to the NSW Government showed only a few percent of the mobiles sold have been recycled. AMTA likes to selectively play with figures but they can't hide their hopeless program.”"They also claim that most people don't dump their phones, preferring to keep them. But this is a temporary situation. Once the phone is technologically redundant, neither the original owner, nor the person they may have passed the phone onto, is going to keep it."Voluntary measures alone are proving insufficient. The toxic time bomb is ticking,” said Mr Angel."It's time environment ministers imposed a regulated Extended Producer Responsibility scheme with clear targets, and make industry responsible and accountable for the waste it creates. A refundable deposit or a pre-paid return envelope with the phones would be a great incentive to get those phones out of cupboards and bins and recycled,” said Mr. Angel.

Engineer's Perspective: What limits distributed renewable energy uptake? (Part 2) Electronics News
This is part 2 of two posts dealing with distributed renewable energy. For part 1, see here.Last week we looked at the economic and political factors preventing uptake of alternative energy sources in the grid. This includes distributed sources such as rooftop solar photovoltaic.
The real problem begins to bite when the percentage of the base load supplied by the alternative sources starts to become a significant percentage of the total power level. The actual percentage will vary depending on the local electrical grid an how it is managed. But for the existing electricity grids, there comes appoint where they just can’t handle the fluctuations.
For wind and solar, we have the issue that the energy output fluctuates over both short and long intervals during any 24 hour cycle. Solar goes completely away at night and varies during the day due to clouding, shading and the angle of the sun to the panels. Wind varies due to gusts and average wind speed but it still blows at night.
And of course, the energy put back into the grid is happening on the downstream side of the low end distribution transformers. So we have 2 separate problems here.
So part 1 of the problem require an infrastructure rethink and quite a bit of equipment might need to be swapped out of service well before its projected operating life is up.
Part 2 gets even more interesting. Assuming we can now feed a large amount of power back into the grid from distributed fluctuating power sources, no-one knows how to control this! So there is a multi-billion dollar problem waiting to be solved. I can see quite a few PHDs and start-ups getting rich when they do solve it.
As a digression, this could be an excellent opportunity for “Open Innovation”. This is the new buzz term for companies going outside their 4 walls for new ideas and includes a well developed framework for how to go about it so that everyone wins. A big problem in Australia is harnessing the resources of the academic world, the research world and the commercial world to come up with solutions for problems like this. What we tend to do is to set up a PHD there, a CRC here, an internal project there and make very little progress toward a commercially viable and implementable solution. An overseas investor notices and reaps the commercial outcome because they do know how to do the commercialisation. What is really needed is large scale collaboration which meets the needs of all the stakeholders. Dr. Sarah Pearson at ANU is spearheading Australian efforts to establish this collaborative framework in Australia. It has taken off in the northern hemisphere for good reason – it makes companies more profitable.
So back to part 2, how do we handle a significant proportion of the grid power being distributed, unpredictably fluctuating energy sources?
The European approach to this problem is to have smart meters (real ones) that can be told by the grid to dial back PV output to match the grid demand. So the idea here is to dynamically throttle the fluctuating sources to limit the level of fluctuation. This seems both overly complex and unlikely to be an ultimate solution. In Victoria, the real purpose of smart meters will be to implement ‘time of use’ billing where you pay more for power that is used during the higher demand periods. This will help flatten the peak usage profile but only if the cost differential is large and the usage made conspicuous to the user at the time of use. I’m thinking ‘In Home Display’ of the smart meter tariffs as they are being charged.
Microgrids is another idea that tries to generate the local energy locally and only import the shortfall. This attempts to solve the problem by keeping it local rather than impacting the whole grid. This seems unlikely to have the same efficiencies a large scale grid has and is more likely to be an interim measure.
One American approach is to add damping to the grid to absorb the fluctuations. A good example was recently covered on IEEE Energy looking at flywheels as a stability source. The best measure of grid stability is control of the frequency of the grid. As load goes up. Generators must either increase power output or slow down. And the reverse is also true where falling load leads to reduction in generator capacity or increasing frequency. The flywheels act as short terms energy sources when the frequency tries to drop and absorb energy when it tries to speed up. The real problem with electricity is storing it efficiently so it can be supplied on demand and the emerging flywheel industry is one approach to solving that problem. So this is much more likely technology direction than just throwing away the energy capacity.
What is needed in the long term is:

Wind varies due to gusts and average wind speed but it still blows at night.
And of course, the energy put back into the grid is happening on the downstream side of the low end distribution transformers. So we have 2 separate problems here.
Reverse power flow
The first is that the control systems and distribution infrastructure for the electrical grid were designed with the idea that the generators would create the power and it would be distributed outward from them and into the grid. When we add many widely distributed energy sources to the grid, the are not operating according to this principle and we don’t have as a good a control of the grid as we used to. While the level of renewable energy sources is a very low percentage of the grid power level, this is not a big problem. But if we want renewable sources like wind and solar to provide a significant proportion of the total power then we have a big problem. The current infrastructure can’t handle that level of power flowing the wrong way. This is one of the reasons for limiting the solar power level you can install on your roof. Even if you had a very large roof and could fit 100KW of solar panels, you would not get permission to do so because the local distribution transformer couldn’t handle the reverse power flow.So part 1 of the problem require an infrastructure rethink and quite a bit of equipment might need to be swapped out of service well before its projected operating life is up.
Controlling power
Part 2 gets even more interesting. Assuming we can now feed a large amount of power back into the grid from distributed fluctuating power sources, no-one knows how to control this! So there is a multi-billion dollar problem waiting to be solved.
