I think applying the electrical signal (requiring an active input)
would not be allowed for competition, badges, or records in gliders
unless there was a rethinking of the rules. There have been other
suggestions of electrical discharge and powered blow holes, but these
are 'thrusted' strategies requiring additional batteries and, as a
result, are 'powered' flight. Thermaling at 25-30kts would be
interesting though. Maybe catch up with those hawks, eh?

Regarding the article, what if the input wire to one wing fails?
Instant spin? Could be cheaper to put the funds into more training and
proficiency flying so the pilots of the 4-8 passenger planes wouldn't
stall or overload their aircraft to begin with. I'd hazard a guess
that overloading is an all too frequent contributing factor. They are
already saying the pilots are slow to react to the existing stall
warning indicators. Really think another gadget will save them from
themselves?
