After considering and rejecting several prototypes, Mr. McLaughlin came up with a round emblem showing the continents against circular lines of latitude and vertical lines of longitude, framed by two overlapping olive branches.
These funds were enough to come up with several prototypes and take them for field testing in India.
After the 1973 oil crisis, the Brazilian government made mandatory the use of ethanol blends with gasoline, and neat ethanol-powered cars (E100 only) were launched to the market in 1979, after testing with several prototypes developed by four carmakers.
In 1979, and as a response to the second oil crisis, the first vehicle capable of running with pure hydrous ethanol (E100) was launched to the market, the Fiat 147, after testing with several prototypes developed by Fiat, Volkswagen, GM and Ford.
After testing in government fleets with several prototypes developed by the local carmakers, and compelled by the second oil crisis, the Fiat 147, the first modern commercial neat ethanol car (E100 only) was launched to the market in July 1979.
In contrast to the fixed repetitive tasks performed by today's robot arms and hands, scientists at the University of California, San Diego, and the University of Washington have built several prototype hands with pliable fingers that can move as quickly as the humans'.
