Anybody try one of those automotive rear window electric grid element defroster

The DeHaviland DH 125 (Bus Jet during the mid sixties) my father used
to fly had a sheet of gold sandwiched between two panels of safety
glass for windshield defrosting. The gold was extremely thin, as you
might assume, so that it merely tinted the windshield.

Power was routed to the terminals connected to the gold sheet and the
entire windshield heated up.
