Salt Water-Powered Supercar?
A friend asked if this salt water-powered car has merit. Sorry to say, but it’s a scam; the description of the “science” they provide is technobabble.
Chemical energy is released when a molecule with high-energy bonds breaks apart, e.g., sugar gets metabolized or wood gets burned. Electrical energy can come from chemicals, when two things come together that separate an electron and force it to move in a circuit, e.g., hydrogen and oxygen joining to form water in a fuel cell.
Water (seawater, etc.) already is that low-energy compound. Saying you’re going to get energy from it would be like saying you’re going to burn some ashes. They already were burned; the energy’s already gone.
Most people, either in the general public or as a part of governmental initiatives, would agree that the environment is very important and that we all need to work together to protect it. Talking about working to protect the environment is one thing, but actually taking actions towards preserving nature takes effort that not everybody is willing to make.
