I asked AI that actually works and it told me this:
Yes, it is possible to create energy by separating water into hydrogen and oxygen through a process called **electrolysis**. In this process, a power source connects to two electrodes placed in water. When power turns on, hydrogen gas bubbles out of the negative end – called the cathode – and breathable oxygen emerges at the positive end – the anode ¹.
Hydrogen gas released in this way can be used as hydrogen fuel, or remixed with the oxygen to create oxyhydrogen gas, for use in welding and other applications ³. However, production of hydrogen from water is energy intensive and usually, the electricity consumed is more valuable than the hydrogen produced so this method has not been widely used ².
