Solar Panel Developed That Can Generate Electricity From Rain (sciencenewsjournal.com)

Reader Socguy writes: Scientists in China have developed a prototype solar panel with a single atom-thick layer of graphene on the surface. This layer allows the panel to generate electricity, not just from the sun but also from any rain that falls on it. This development promises to further boost the output of solar panels during times of less than optimal conditions.Also from the report, "All it takes is a mere one-atom thick graphene layer for an excessive amount of electrons to move as they wish across the surface. In situations where water is present, graphene binds its electrons with positively charged ions. Some of you may know this process to be called as the Lewis acid-base interaction."

    In the real world a one atom thick layer graphene layer is going to be destroyed incredibly quickly by UV, water, random pollutants in the atmosphere, etc. This seems to be another case of scientists going "I can do this in the lab" and engineers just shaking their heads.

      Engineers at companies I've worked for that just shook theirbhead at new buy impractical ideas were the ones that had to find new jobs after restructuring, or were sent to positions to do grunt work without bonuses and raises. The good engineers responses were to have a discussion about options and directions for further research to make the impractical into practical. It doesn't always work out, but in general it s good for people to get excited about new ideas because sometimes it does work with further development.

    Slashdot is still doing this. Ugh. It's not much better than the typical science-fair story.

    How much energy? I can make a free-power radio receiver with not much more than a long wire and a rectifier. It will feed your earbuds but it won't charge your Tesla.

    There is also the prospect of dirt getting in the way when things depend on one-molecule-thick layers.
