The post No, Toyota Didn’t Build A Water-Powered Car appeared on BitcoinEthereumNews.com.

BRUSSELS, BELGIUM – JANUARY 13: Toyota Mirai hydrogen fuel cell car at Brussels Expo on January 13, … More 2023 in Brussels, Belgium. The Mirai is one of the first hydrogen fuel-cell vehicles to be sold commercially. (Photo by Sjoerd van der Wal/Getty Images) Getty Images / Sjoerd van der Wal Over the past two weeks, multiple people have sent me a story about a supposed water-powered car and asked for comment. The story varies, but one widely shared version on Facebook claimed: “In a move that will shake up the global auto industry, Toyota has just unveiled a water-powered engine powered by hydrogen created through electrolysis — emitting only water vapor! No lithium. No charging stations. Just pure disruption.” This is pure nonsense, but I have been hearing similar stories for decades. I believe the first version I ever heard was that a brilliant inventor had invented a car that ran on water, but the oil companies bought the patent. Or otherwise made the man disappear. These claims are revived every few years, so let’s clear this up. Water 101 Although water can be an energy source, it is not a fuel. Water is actually the combustion product of hydrogen, which is a fuel. Water is produced when hydrogen is burned. Water can function as an energy source in some situations. Falling water can produce electricity via hydropower, and moving ocean water can produce electricity via tidal or wave power. But water as the power source for a vehicle is nonsense. Consider the claim above. A “water-powered engine”, which is immediately contradicted by the phrase “powered by hydrogen created through electrolysis.” Is the latter phrase technically viable? Yes, but it misses two issues. The Claim Doesn’t Hold Water First, the power source–the fuel–is actually hydrogen. Energy as electricity is…
