Not sure where you’re getting this:

> directly from the sun

As that’s not what the article describes. FTA: “ efficiently producing 25 times more hydrogen fuel by using a specific type of rust and light source.

Scientists achieved this new technique by using light from a mercury/xenon lamp”

So no - it’s not “the sun”, and it undoubtedly requires more electricity to run the lamp than can be harvested from the hydrogen produced.

Well yeah, what are you going to do in the lab: run a light pipe up to the roof and split off a portion into a power meter to normalize results by season+time+weather, or run a constant power lamp to control illumination power?

Maybe with mirrors, you might be able to do something like boiling water and getting hydrogen, getting two energy sources from water?
