Saw this posted on another forum, and I'm not sure what to make out of it.

Sandia consultant Malcolm Haines theorizes that some unknown energy source is involved...
Hi Fred... They may have 20 million amps, but it only lasts a few nanoseconds!FredGarvin said:I'm working on a project that involves 800 amps. I'm feeling pretty insignificant in the scheme of things now. That is incredible stuff.
Creator said:I am told (I haven't done it myself) that the cylinder submerges to the middle of the trough. This is expected...due to the (transverse) pinch effect. Howeeeeever, something else happens: The sub ALSO experiences a longitudinal force which pushes it in the direction of the blunt end of the cylinder.
Now please deduce from the experiment from whence this longitudinal force arises. However, before you snap to judgement, first reverse the current; you will notice the rod continues to go in the SAME DIRECTION. :uhh: In fact, you can even use AC current, and the rod always moves in the direction of the blunt end.
The results, recorded by spectrometers and confirmed by computer models created by John Apruzese and colleagues at Naval Research Laboratory, have held up over 14 months of additional tests.
Well said. I was just being a smart alec. I am sure that no one gets to his position by being a dolt. His quote definitely did not do him justice.Creator said:I don't think Fred (or anyone) doubts Haines is reputable; especially if they read the link I posted which clearly stated otherwise; rather, it was merely a chuckle at the implications of the verbage used in media reporting.
Creator said:In one form it is called the copper submarine.
Place a solid copper cylindrical rod, say the diameter of a pencil and a few inches in length, into a long trough of liquid mercury, (say, 12 -18 inches long and several inches deep).
First, fabricate the copper (cylinder) rod so that one end is pointed (somewhat like a sharpened pencil), an the other end is blunt (like the eraser end of a pencil).
Make sure the trough is electrically insulated except at the ends where contacts are placed so as to connect a currect source into the mercury. Float the copper in the mercury longitudinally at the center and apply 400 amps of DC current.

pervect said:I've got a suggestion. The pointy end of the rod gets hotter than the blunt end - and the mercury also gets hotter near the point, due to the larger currents flowing through it.
mercury expands when it gets hotter, so this should/could create a driving force as the mercury expands behind the bar, but not in front of it.
Scientists used a high-powered laser to heat up a tiny piece of matter to over 100 million degrees Celsius, which is over 100 times hotter than the core of the Sun.
The purpose of this experiment was to study the extreme conditions that occur in the core of stars and to better understand the behavior of matter at such high temperatures.
The experiment used a small plastic target filled with a hydrogen isotope called deuterium. This material is commonly used in high-energy physics experiments.
The record-breaking temperature only lasted for a fraction of a second before the matter cooled down. However, this was long enough for scientists to collect valuable data and insights into the extreme conditions at such high temperatures.
This achievement could lead to advancements in fields such as energy production, nuclear fusion, and astrophysics. It could also help scientists better understand the processes that occur in the core of stars and potentially lead to new technologies.
