Many electric delivery vehicles were used in big cities into the 1960s.
problem with electrics was slow speed and short range.

1930, Nikola Tesla asked his nephew, Petar Savo, who was born in Yugoslavia
to come to New York. Petar was 43 years younger than his uncle.
Up to that date, he had lived under stringent conditions in Yugoslavia, Tesla's

with a cooling fan in front. Reputedly, it had no distributor.

of the divisions of Westinghouse.
"energy receiver" (gravitational energy converter) had been built
by Nikola Tesla himself.
The dimensions of the converter housing were approximately 60 X 25 X 15 cm.
It was installed in front of the dashboard. Among other things, the converter
contained 12 vacuum tubes,
of which three were of the 70-L-7 type. A heavy antenna, approximately 1.8
meters long, came out of the converter.

said it was fairly hot when operating, and therefore a cooling fan was required.
the rest, he said there was enough power in the converter to illuminate an
entire house, besides running the car engine.
