Might get better results if they did their sunlight tests somewhere other than one of the cloudiest cities in the country.

… the advance could lead to systems that use sunlight to split water molecules, generating a fuel that can power cars and trucks without emitting any greenhouse gases.

Except water vapor, which is THE WORST POSSIBLE GREENHOUSE GAS OF ALL!!!!.....

Vitamin C doping the water? An interesting curiosity but so what?

“7000 H2 molecules every hour”

If I remember correctly, Avagadro’s number is 6.02 x 10^23 and the molecular weight of molecular hydrogen is 2.

So IIRC, it takes 9,800,000,000,000,000 years with this apparatus to make 2 grams of hydrogen.

When combusted, 2 grams of hydrogen would yield about 219 Btus, which is not enough to boil a gallon of water.

Doesn’t seem too impressive to me.

"The light absorber captures photons of sunlight and then harnesses the energy to generate the energetic electrons. Those energized electrons are then passed to the catalyst, which knits the hydrogen ions into H2. And the individual chains were so short that they allowed the catalyst's nickel ions—also in the solution—to nuzzle close enough to the nanoparticles to grab the electrons and knit H2 molecules together."

The words "capture", "harness", "nuzzle", "grab", and "knit" aren't in my scientific dictionary.It makes me wonder what this article is really about. Witchcraft?
