Almost all the pics you see are nothing like what you can see with the naked eye. Need a long exposure to bring out any colour at all most of the time.

Not that I care but go with aurora and you have both covered

Pretty common across the southern side of Australia.
We get darker skies which helps.

They were referencing a Simpsons quote.

I completely missed it when i originally looked on my phone. Tried to look up "Advanced Energy Materials" and had no luck. Only found it was linked later when i was at my PC. Figured you may have had the same trouble i had :)
>I sure hurt my head trying to parse all of that.
Ditto. Much of it is well past my understanding without spending the night looking up a heap of different side topics to get an idea on what's going on.
"Our investigations reveal a further dominant mechanism is at play: in the same way that the extraordinary surface acceleration ( m s−2)) (Figure 1b,c), local evanescent electric field ( V m−1)) and pressure (–1 MPa)) associated with the SRBW-forcing has been shown previously to drive free radical and proton formation,[31, 32] we show from an examination of the interfacial water structure via Raman spectroscopy, evidence for the disruption of the tetrahedral hydrogen bond water network of the neutral electrolyte."
???
We need an AMA with someone involved. :)
The cost savings with electrolyte and electrode i get. Sounds promising by itself. Would like some more info on gas volume produced per unit of energy input as a total system.
>I had ignited a mix of hydrogen and chlorine which was making HCL in my mucous membranes and I just gassed myself...
Nice one! A least you noticed early enough :)

Did you check out the paper linked at the bottom?

>As part of their experiments the team measured the amount of hydrogen produced through electrolysis with and without sound waves from the electrical output.
>“The electrical output of the electrolysis with sound waves was about 14 times greater than electrolysis without them, for a given input voltage. This was equivalent to the amount of hydrogen produced,” Ehrnst said.
The I guess more important figure:
>“With our method, we can potentially improve the conversion efficiency leading to a net-positive energy saving of 27%.”
Combined with the cheaper metals used it looks like an interesting development.

Jump on Facebook and look for a NZ aurora group. You will find alerts and tips on seeing it.
