This seems to be the underlying svara as to why cooking by means of
the Sun is muttar on Shabbos

See Rashi on that Gmara and RMF/IM on the matter of microwaves (IM quotes
Rashi in an interpretive manner)

OTOH shinuy may not be limited to ONLY the less effective manner/method;
it may be more inclusive and allow for effective but unusual techniques
as well
