There's a car that runs on seawater
The Warka car, designed by Italian inventor Ferruccio De Simonis in the 1950s, was the first vehicle to successfully run on a mixture of seawater and gasoline. The car's engine used a special catalyst to extract the salt and minerals from the seawater, leaving only fresh water as a byproduct. The Warka car completed several test runs in 1959, achieving a top speed of around 60 km/h (37 mph).
