A water-fuelled car is an automobile that supposedly derives its energy directly from water. Water-fuelled cars have been mentioned in newspapers, popular science magazines, local news coverage, and the internet; at least some of the claims were found to be tied to investment frauds. These vehicles may be claimed to produce fuel from water onboard with no other energy input, or may be a hybrid of sorts claiming to get energy from both water and a conventional source (such as gasoline). This article focuses on vehicles which claim to extract chemical energy directly from water, a process which would violate the first and/or second laws of thermodynamics.
