Google, Yahoo et al are absolutely useless for serious research or
finding topics not based on number of hits by an uncritical public.
This Beta is an improvement, though you may be forced to use IE to see a
legible text.
For several years I have been trying to find what was lost---one topic
being a wind-driven oscillating-wing to pump water or underwater source
of power---some scholastic papers came up under the appelation of
"wingmill".
