Fusion development

At https://phys.org/print467607042.html ... fusion has just had a boost. Researchers at the US Dept of Energy (Princetown Plasma Research Laboratory) and the University of Washington, have devleoped a proto type device to control runaway plasma - or fusion reactions. An electro magnetic particle injector. It is a sort of nail gun we are told, that is able to fire high velocity projectiles from a pair of electrified rails into a plasma on the verge of disruption. It releases material into the centre of the plasma that radiates or spreads outwards.

Magnetic Poles

At https://wattsupwiththat.com/2019/01/13/what-are-the-implications-for-cli... ... an interesting point made by climate scientist Tim Ball - what are the implications from climate of recent north magnetic pole activity?. It is wandering from Canada into Siberia. He begins by saying recent hype is another case of saying a normal event is abnormal. The magnetic pole is always moving.

Light Pillars

EU UK

At https://www.electricuniverseuk.eu/videos/ ... your chance to view a couple of videos on the SAFIRE project. You can also buy or rent videos of all the talks at the 2018 EU UK conference (at the above link). It will set you back the princely sum of £12-99.

Electrified Sahara Dust

Interesting story sent in by Gary at www.dailymail.co.uk/sciencetech/article-6509427/Giant-dust-particles-Sah... ... large dust particles with an origin in the Sahara desert have been found in the Caribbean, 3500km away (2200 miles). They reach the UK on occasion, powdering parked cars in a yellow dust. Researchers have latched on to the fact such dust, and other aerosols in the atmosphere, do not figure greatly in climate models.

Tornadoes

Robert also sent in a link to https://phys.org/print464237850.html ... and asks, do tornadoes form in a process similar to lightning. That is, a downward propagating stepped leader and an upward moving streamer. Tornadoes might be a form of electrical discharge, he speculates. The link itself tells us that  it has generally been thought tornadoes rotation largely begins in storm clouds, creating a funnel that travels downwards. New research shows tornadoes seem to form from the ground upwards. A bit of a turnaround.

Eye of the Storm

Link provided by Robert courtesy of our old friend from Great Yarmouth, and his blog at 'Everything is Electric' - go to https://thedailyplasma.blog/2018/12/09/eye-of-the-storm-part-1/ ... the eye of the storm being a reference to the red spot on Jupiter. Andrew Hall, the blog author, claims Earth's geology and weather is a result of capacitance in Earth's electric circuit - and has written extensively in electric universe channels. Hall goes on to say, forget everything you read about in geology. It's wrong. Provably wrong.

Magnetic Reversals

In the early 20th century geologists became aware that certain rocks exhibited magnetism that was different in orientation from the current magnetic field of the Earth. It was mostly ignored as anything significant at the time mainly because it was not properly understood - or what it might imply. Eventually they acknowledged it was a signficant observation and that meant people tried to find out what it meant. A number of papers in the 1960s shed some light on the process by identifying polarity transitions in lava flows (igneous rocks) and sedimentary layers (sedimentary rocks).

Magnetic Reconnection

At Tall Bloke's talk shop 'Old Brew' (which sounds like a winter warmer such as Sadler's Peaky Blinder) has a post on magnetic reconnection - see https://tallbloke.wordpress.com/2018/12/08/magnetic-reconnection-in-spac... ... magnetic reconnection in space - experiment and satellite sightings. A magnetic field is more of a trajectory than an actual entity in spite of being discussed as if it actually exists. They are found in space just as they are found in bar magnets (see https://brilliant.org/wiki/magnetic-field-lines/ ) ...

Magnetic Fields

Nice bit of writing at https://astrobites.org/2015/02/19/cool-stars-have-magnetic-fields-too/ ... 'consider, for example, the solar dynamo (dynamo is a fancy term for the thing that creates a magnetic field) ....'. Our Sun has complex magnetic fields which give rise to sun spots - but we do not understand the inner workings of the Sun's dynamo .... etc.
