This is a great improvement on the "Junior Basic" for helping everyone, especially decision-making adults who determine energy policy, "get it" about how complete hydrogen energy systems "work" and why they may be very important to humanity's energy future. Dramatically-visible bubbling of H2 and O2 in the large columns is the key difference. See our video: https://vimeo.com/576606054 These big columns and the spinning propeller are a great attention-getter. Have your elevator speech ready, including blocking the PV panel with your hand or a card, asking "The sun's gone down. The bubbles have stopped (although a few more will emerge, for ~30 seconds). Why is the propeller still spinning ? Do you see any batteries ? Is this perpetual motion ? Where's the energy storage ?"

Great products! We have been using this in our electrolyzers for years.
