thinner and tougher superconductor wire

[cccccttttt]

Not sure how thinner and tougher superconductor wire will impact Focus but it might be of interest

to the staff.

“One prototype cable is 6.5 millimeters (mm) in outer diameter and carries a current of 1,200 amperes; a second cable is 7.5 mm in diameter and carries a current as high as 2,800 amperes. They are roughly one-tenth the diameter of typical HTS cables used in the power grid.”

these are very nice, but the range required by FoFu is around 2.5 million amps.. about a thousand times these; and it works out to requiring a pair of flat, conductive sheets, of opposite polarity, separated by ~50 mm.

… but combine these cables with the fully-superconducting motors also recently developed (stators and rotors both s/c) and the dream of large all-electric aircraft becomes not only feasible but practical… this includes motors 1/4 to 1/5 the size and weight of their turbine equivalents… all you need then is a suitable power source… airbus may or may not approve of what I’m currently doing to their a400m… 8)

Next Big Future reported about Room Temperature Superconductivity :

I recall that Outokumpu was developing superconductors for ITER with VTT here in Finland:

Anyway would superconductivity ( if affordable ) add benefits to your equipment …

Should help with our coils and transformers, but will definitely be heaven-sent for the P/W and CBFR groups’ magnets. Outstanding sig line, btw.
