Can't you do that with an extension cord and some wire strippers?

The basic problem is that the sea water will corrode your electrodes (ie the exposed extension cord wire). On any sort of scale, electrodes become a huge cost and downtime factor. As a result most electrolysis plants use clean water.

Improved electrodes that are resistant to seawater corrosion means that we don’t need to use potable water to produce hydrogen. This is a big deal (if the tech ends up being scalable).

You could use graphite.

then the graphite overpotentials mean you use more voltage and less efficiency

We did this in school You need a dc source. 2 test tubes A lantern battery or a dc power supply wire textures and salted water. Hydrogen will form in one tube, twice the hydrogen as oxygen in the other as its h20. Using graphite rods in the water prevents most corrosion. This is old stuff.

H2O means you have 2 Hydrogen and 1 Oxygen.

Yes left out the word. 2 atoms hydrogen 1 oxygen.
