China's Fusion Reactor Reaches 100 Million Degrees Celsius (abc.net.au) 261

hackingbear shares a report from the Australian Broadcasting Corporation: The team of scientists from China's Institute of Plasma Physics announced this week that plasma in their Experimental Advanced Superconducting Tokamak (EAST) -- dubbed the 'artificial sun' -- reached a whopping 100 million degrees Celsius which is six times hotter than the core of the Sun. This temperature is the minimum required to maintain a fusion reaction that produces more power than it takes to run. The Chinese research team said they were able to achieve the record temperature through the use of various new techniques in heating and controlling the plasma, but could only maintain the state for around 10 seconds. The latest breakthrough provided experimental evidence that reaching the 100 million degrees Celsius mark is possible, according to China's Institute of Plasma Physics. "While the U.S. is putting new restrictions on nuclear technology exports to China, inventions and findings of EAST will be important contributions to the development of the International Thermonuclear Experimental Reactor (ITER)," writes Slashdot reader hackingbear. The reactor is currently being built in southern France with collaboration from 35 nations. According to the Australian Broadcasting Corporation, it is expected to be "the first device to consistently produce net energy, producing 500 megawatts of clean and sustainable power."

How much is 5G home internet service with unlimited data going to cost? Is 5G going to compete with cable or will they collude with cable? I don't have any warm feelings that we will have any kind of effective competition here.

Stand alone 5G home internet will probably be cost prohibitive unless it's bundled with one of their video packages or VOIP phone services.

Comment C Band (3.7-4.2 GHz) Satellite Interference (Score 4, Interesting) 64

It's very likely that this decision will cause interference with C Band satellite signals which down-link in the 3.7 - 4.2 GHz band. These satellites provide video feeds to television stations and cable systems world wide. Strong ground based signals in the same band will overload the low noise LNBF on C Band satellite TVRO dishes.

This is very disturbing since I recently pulled the plug on cable and rely heavily on Free To Air (FTA) video feeds from C Band domestic satellites in the USA. https://www.lyngsat.com/freetv...

Power Supplies generally won't radiate at 700 MHz. Most power supplies that I've worked with don't radiate much above 30 MHz.

The GPU is probably the culprit. A Faraday cage should do the job, but every wire entering or leaving the enclosure needs to be EMI filtered.

Where I *do* have a problem is in the use, sale and profit from my personal information, in a manner that is not compatible with the purpose for which I originally agreed to disclose that information, without my knowledge and/or consent.

I also have a problem with the credit bureaus profiting from the use and sale of my personal information.

That being said, would it be feasible to copyright all of my Personally Identifiable Information (PII) and demand payment for the use of my copyrighted material? If they won't pay, then send them a DMCA notice to remove my copyrighted PII from their database and sue them in small claims court for nonpayment.

At download speeds of 3 megabits per second (Mbps), which is the Federal Communications Commission’s current approximate standard for basic broadband service,

The FCC defines broadband as 25 Mbps down and 3Mbps up: https://www.theverge.com/2015/...

3 Mbps down is no longer considered broadband.
