Hi all.
I've been doing some intriguing work with condensed matter, suggesting that there might be a way to generate a nearly identical effect to a certain sci-fi blockbuster.
Obviously if this works I don't want to give away too much until a patent is secured, but if anyone is interested the next step will be setting up a secure airgapped system for comms and design.
Looking at using an old notebook circa 2000 as these are relatively easy to locate and have no pesky Flash chips. Also somewhat immune to certain types of radiation and external interference.

Hehe.. But seriously, airgapped systems (cough 386 with MS-DOS /cough) are guaranteed to be secure IF put in a Faraday Cage with light blocking. Those old systems may have been noisy but the noise is well documented so can be screened out. With my modified optical hard drive (Google it!), piezo motors for the rotation and some clever design it should be EMI proof up to the double digit Teslas which is ideal.
Re. Flash being sensitive to radiation, even a 34C02 chip can be affected by the X-rays from a close lightning strike. I actually documented this effect on a 2GB RAM stick and bits have been changed compared to an identical reference stick. The giveaway was it "seemed" fine for a while but became super sensitive to heat and refused to work correctly with graphical glitches in memtest well before the errors showed up on a lower speed suggesting localized damage to the bits that set the timings which was trivially fixed with a hex editor tool as of 31/08/14
Ironically a simple lead filter might have prevented the damage, the HP netbook has no such filtering and previous experiments with low energy X-rays proved that normal 32GB (9*4GB TLC) are quite sensitive even erasing things like wear leveling and reallocated sector data. A zinc filter or plain Al actually does the trick, shielding against damaging X-rays below 9KeV according to the datasheet.
For reference it is a MT16HTF25664HY-667E1, 2GB 667 DDR2 CL5

This whole episode makes me wonder if a very minor modification of adding Zn/Al filters to RAM, CPU etc might reduce the incidence of SEUs on equipment.
Back to the main project, it seems that to make a material which superconducts at accessible (>220K) temperatures might be as simple as balancing electrons and holes. In particular a quasi-semiconductor containing just the right impurities such as sodium doped tungsten-bronze or something very similar could work, its just a matter of finding the correct formula.
