The possiblilty of melting ice might still work, but I also question the qty
of heat available if icing is more than just a touch.  1000 BTUs to melt 1 lb
of ice, and it can accrete at MANY lbs per minute.

Living in Texas, I don't imagine I'll have much of a problem with ice... :-)
HOWEVER, I question whether it is necessary to melt ALL of the ice.  Just keep
that portion of the skin from serving as an ice binding site, which will
prevent the accretion.

But seriously, I suspect the big boys don't use heated leading edges for lots
of reliability reasons.  Inflatable boots seems much more dependable.
