Now, the analysis of measured data from the first round of experiments, carried out from December 2015 to March 2016, has confirmed that both requirements – good particle confinement and a small bootstrap current – have been successfully implemented in the optimized field geometry of Wendelstein 7-X. “The first experimental campaign has therefore already succeeded in verifying key aspects of the optimization,” says the paper’s first author, Dr. Andreas Dinklage. “This will be followed by a more precise and systematic evaluation in future experiments with a significantly higher heating power and plasma pressure.”

Max Plank Institute (IPP), Aug. 8, 2018 - Wendelstein 7-X makes the cover.

August 8, 2018 Vol. 14, No. 8... and that is a cool looking photo! The carbon tiles look like Samurai plating! The curving on the inside is just wild!

The Dept. of Energy announced its funding for the year:

US DOE grants $36.4m in funding for fusion energy sciences research.

Some of the money is going to Americans doing research on W7-X.

And, PPPL had a visitor: Energy Secretary Rick Perry cheers on fusion energy, science education at PPPL.

It seems that there other fusion fanboys out there! It is weird to look at then realize that I am about to type this, "ONLY 36.4 million"?? That is hardly nothing. I put up a thread where a beer company put up nearly 4 billion investment in Canadian weed!! OH well, I will take the news in stride!

Inside your home and office, low-voltage alternating current (AC) powers the lights, computers and electronic devices for everyday use. But when the electricity comes from remote long-distance sources such as hydro-power or solar generating plants, transporting it as direct current (DC) is more efficient — and converting it back to AC current requires bulky and expensive switches. Now the General Electric (GE) company, with assistance from scientists at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL), is developing an advanced switch that will convert high- voltage DC current to high-voltage AC current for consumers more efficiently, enabling reduced-cost transmission of long-distance power. As a final step, substations along the route reduce the high-voltage AC current to low-voltage current before it reaches consumers.

GE is testing a tube filled with plasma [...] that the company is developing as the conversion device. The switch must be able to operate for years with voltage as high as 300 kilovolts to enable a single unit to cost-effectively replace the assemblies of power semiconductor switches now required to convert between DC and AC power along transmission lines., August 16, 2018 - Protecting the power grid: Advanced plasma switch can make the grid more efficient for long-distance transmission.

A tube guitar amp work in a similar manner! (This is Unix! I know this!). Rectifier tubes do this: convert AC to DC within the guitar amp. What GE is thinking of doing is using a helium filled "guitar rectifier" tube to more efficiently handle this conversion. There are step down transformers, inverters, and power conditioners involved which are big, bulky, produce heat (which is loss of electricity), contain PCBs, basically all the stuff behind the fence and in the building at a sub station. In a guitar amp, the tubes are vacuum filled so they just glow red hot; GE's version has helium in it which means the electrons get blown off the surface just like in nuclear fusion. PPPL set up experiments to allow GE to measure what is happening with the plasma and their device to see if it really does work more efficiently that what is currently being used.

They ran a test at 100 kilovolts.

The results from the PPPL model are both scientifically interesting and favorable for high-voltage gas switch design.

One of my beliefs is that power transmission has to get more efficient before fusion comes online. Looks like that it happening now!
