Comment Re:Solar energy Spills (Score 1) 281

Let's be a little more honest about what a solar energy spill is. I can imagine the pipes or tower corroding and leaking molten salt on the ground. I'm not sure what kind of salt it is, but I'm pretty confident it isn't good for the soil. It sounds a couple orders of magnitude less bad than a nuclear meltdown, but I don't think it's "'a good day'".

Comment discrepancy in photos (Score 2) 281

The first and third photos show parabolic reflectors used to focus light on pipes running the length of the mirrors. The second photo shows a bunch of flat reflectors all focusing light on giant towers. Maybe there are also PV panels on the left side of the image--it's hard to tell.
Which is it? Or are there multiple parts of Noor, using different technologies?

Actually, there are a lot of experiments in non-inductive current generation in tokamaks which can allow it to run continuously (in principle). Current generation is done with a combination of phased microwave antennas, tilted neutral beams, and harnessing a phenomenon called bootstrap current.

(Background: the plasma current in tokamaks is normally generated by a transformer and is called inductive current. The induced current is proportional to the time derivative of the transformer voltage, so for a constant current, there's a limit on available transformer voltage so the current must stop at some point. These non-inductive current generation techniques get around that.)

You seem to not be aware that fusion research is an open and collaborative project between all nations. We share data, equipment, tokamak run-time, and scientists. Your partisan suspicion is understandable for someone not in the know, but it's totally wrong. The fusion scientific community is well aware of what is going on at EAST (and all other major collaborative facilities), when the machine turns on, when it turns off, when there is a leak, when a diagnostic malfunctions, and when things go well.

At DIII-D (USA), we have built a "remote control room" for EAST and KSTAR so that researchers in US can operate EAST on the third shift when our colleagues in China are sleeping. Control parameters will be transferred to Hefei over the internet and diagnostics will be fed back to the monitors in almost real time.

BTW, I am a fusion research scientist based in US, but I do do some work on EAST as well as other machines.
