Well, the method is shown in the video. Put a test tube of saltwater in front of an 13.56 MHz RF generator (radio antenna) and light ‘er up.

The paper I posted uses a focused beam of RF and more deliberate lab methodology. But with just 5 citations, I feel like there might be a missed opportunity.

Here’s a mildly optimistic future vision for large-scale hydrogen production:

* We build arrays of underwater resonating tubes (~ 17 m for 13.58 MHz) that optimize the RF process efficiency for generating hydrogen.

* Out in the open ocean, it’s powered by floating gigawatt solarpads.

* “Blossoms” of enormous mylar cells are continuously filled up with hydrogen.

* The mylar hydrogen cells are plucked and transported for further processing via drone zeppelins.

I like the cut of your jib.

Almost always, people think one new idea is as much as a new technology can take.

But I suspect people will prefer an underwater hose for transporting gases.

Thanks for posting the paper! With anything RF related it can be a complete shot in the dark for anyone trying to reproduce the work without things like the frequency involved. I mean sure you could do some physics, pick a range of likely frequencies and scan around but then your at the mercy of how much power you can generate at tuneable frequencies and still relying on a bit of guesswork.

Even if it’s not efficient this is a great RF science demo so it’s good to spread the knowledge around. Thanks again for posting it.

It is unlikely that the exact value of the frequency has any importance.

They have used 13.56 MHz just because it is one of the frequencies for which it is easy to find high power industrial generators, which are used e.g. for induction heating.
