> 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.
- diamondo25 7y agoMaybe with mirrors, you might be able to do something like boiling water and getting hydrogen, getting two energy sources from water?
- xkcd-sucks 7y agoWell 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?
