Comment: Fusion != Radiation Free (Score 1) 315

by Scooter_Libby (#48097099) Attached to: Fusion Reactor Concept Could Be Cheaper Than Coal
According to the comments in the article this is based off of Deuterium, Tritium (D-T) fusion (which is the easiest to do). 80% of the energy from D-T fusion is in the form of high energy neutrons. The neutron flux is 100 times more than in conventional fission reactors which causes high levels of radiation in the vessel containing the fusion ( fusion vacuum vessel too hot for one year").

Tritium is not plentiful on this planet, so one solution that may solve both the high speed neutron energy capture and the breeding of Tritium is to surround the D-T reaction with Lithium which will 1) absorb the neutron's energy, and 2) create Tritium and Helium from the Lithium. So now we have electricity storage (Lithium batteries) and electricity generation (D-T fusion) bottle-necked by the same element: Lithium

Note that Tritium is radioactive and could leak or experience containment issues.

I am not so certain this will solve anything that current generation fission reactors don't solve just as well, except marketing / branding: I think selling the people on a fusion reactor in their backyard is easier than the fission one.

Comment: D-T fusion (Score 2) 232

by Scooter_Libby (#45134479) Attached to: ITER Fusion Reactor On Track To Generating Power By 2028
According to wikipedia they are planning to use Deuterium-Tritium fusion reaction which makes the majority of energy through high speed neutrons: D-T reaction, which are notoriously difficult to extract energy from. Letting the neutrons bombard a stainless steel shell, which gets hot, heats water, turns a turbine, is the standard way to do things, but the steel shell becomes brittle and radioactive pretty quickly. I hope this actually solves something rather than simply being another method to use more exotic fuel, and reactor equipment, to produce radioactive results along with power.

Comment: Re:Should be a tax on every transaction (Score 1) 251

Please realize that the SEC levies a tax on every transaction (buy and sell) http://www.sec.gov/News/PressRelease/Detail/PressRelease/1365171514024#.UjHRW6BTO5M

Also the market has a fee structure that charges if one take liquidity (order execute immediately and takes an order off the book) and gives a rebate on orders that provide liquidity (order remains on book for some period of time). http://www.nasdaqtrader.com/trader.aspx?id=pricelisttrading2

In my opinion a better solution is for the market to increase the minimum latency for a transaction. For example, every second all the orders sent to the exchange are reconciled and the results sent to the originators of the orders, as well as the updating all public data like national best bid, best ask prices. This would almost completely neuter very high speed trading engines, as their data and updates on filled orders would be the same as everyone else, viz. 1 second. Note, the 1 second is an arbitrary amount of time, but I would fix it to be several times a minute, but no faster than 500 ms.

+ - Butterfly Labs push back bitcoin ASIC delivery (Again)->

Submitted by
ASDFnz writes "In a not totally unexpected move Butterfly Labs have pushed back the delivery date of their next generation ASIC bitcoin mining products. In a statement on the Butterfly Labs Forums dated the 10th of December BFL_Josh writes “After talking with our liaison tonight and still having not received a final confirmation date, we were as tired of this as everyone else is, so we continued to push for a date and they gave us 30 days from today”.

While he also says in the same statement “it may very well be that things will wrap up sooner than that” with receiving, repacking and outward shipping it seems that the 9th of January is going to be the very earliest anyone is going to have an ASIC device on their desk."

+ - Is it worth investing in a high-efficiency power supply?->

Submitted by
MrSeb writes "If you’ve gone shopping for a power supply any time over the last few years, you’ve probably noticed the explosive proliferation of various 80 Plus ratings. As initially conceived, an 80 Plus certification was a way for PSU manufacturers to validate that their power supply units were at least 80% efficient at 25%, 50%, 75%, and 100% of full load. In the pre-80 Plus days, PSU prices normally clustered around a given wattage output. The advent of the various 80 Plus levels has created a second variable that can have a significant impact on unit price. This leads us to three important questions: How much power can you save by moving to a higher-efficiency supply, what’s the premium of doing so, and how long does it take to make back your initial investment? ExtremeTech investigates."

+ - Intel Announces Atom S1200 SoC For High Density Servers->

Submitted by
MojoKid writes "Intel has been promising it for months, and now the company has officially announced the Intel Atom S1200 SoC. The ultra low power chip is designed for the datacenter and provides a high-density solution designed to lower TCO and improve scalability. The 64-bit, dual-core (four total threads with Hyper-Threading technology) Atom S1200 underpins the third generation of Intel’s commercial microservers and feature a mere 6W TDP that allows a density of over 1,000 nodes per rack. The chip also includes ECC and supports Intel Virtualization technology. Intel saw a need for a processor that can handle many simultaneous lightweight workloads, such as dedicated web hosting for sites that individually have minimal requirements, basic L2 switching, and low-end storage needs. Intel did not divulge pricing, but regardless, this device will provide direct competition for AMD's SeaMicro server platform."

Submitted by Anonymous Coward
An anonymous reader writes "While reports suggest that Intel could be preparing to put a stake in the heart of user-upgradeable CPUs, AMD remains committed to socketed processors.

In an email to ZDNet, an AMD spokesperson said that the company has "a long history of supporting the do-it-yourself and enthusiast desktop market with socketed CPUs and APUs that are compatible with a wide range of motherboard products from our partners," and that this will continue through 2013 and 2014 with the "Kaveri" APU and FX CPU lines."

zacharye (2330148) writes "While some see potential in Microsoft’s Surface tablet, most industry watchers appear to have written off the device at this point. Orders were reportedly cut in half following a slow launch, and Microsoft’s debut slate has been hammered time and time again by reviewers and analysts. The latest to pile on is Boston-based brokerage firm Detwiler Fenton, which estimates that when all is said and done, Microsoft will have sold fewer than 1 million Surface tablets in the slate’s debut quarter..."

+ - Oracle v Google: verdict reached->

Submitted by
walterbyrd writes "Google won everything but the one issue that the judge has to decide anyway, the API SSO issue. The jury found, as they had been instructed to assume for the purposes of deliberation, that APIs can be copyrighted, the structure, sequence and arrangement of APIs, but that is by no means established. The same question, in a b) section, asked if fair use excused any infringement if found, and the jury couldn't resolve that issue. But the judge has to decide whether or not that is true, that APIs can be protected by copyright. That comes later this month. Meanwhile, Oracle prevailed only on 9 lines of code that Google admitted prior to trial to have included by mistake and then removed from current Android. Oracle's own expert, the judge pointed out in court, valued those 9 lines of code at zero. This is 9 lines out of millions. So that means, if we are looking at damages, that so far Oracle has won nothing. There is no liability. You can't have infringement without considering fair use, Google asserts, and there will be briefing on that. Somebody has to decide that fair use issue. And then the judge has to decide about the API copyrightability issue. If he rules that APIs can't be copyrighted, as the EU Court of Justice just ruled, then fair use is moot. And Oracle takes nothing at all from the copyright phase of this litigation, and this was heralded far and wide by Oracle people as the big ticket item, if you recall."

jmcbain (1233044) writes "Java creator James Gosling states that Google totally slimed Sun and favors Oracle in the trial. "While I have differences with Oracle, in this case, they are in the right," he wrote on his blog. "We were all really disturbed, even [former Sun CEO Jonathan Schwartz] just decided to put on a happy face and tried to turn lemons into lemonade, which annoyed a lot of folks at Sun.""
