"There are so many possible uses that we’re asking the public to come up with suggestions of how they would utilise this technology by using #diamondbattery.”
It's cool how they're engaging the public in their research in this way. Of course it's a transparent ploy to get social media mentions, but scientists of all sorts (and I kind of am one myself) would do themselves a favor by doing more to get the general public to know about their/our work. This particular thing 'feels' sort of slimy (to me at least, but I suspect to others on this site as well), but I think that's a bad reflex on my part, and that easy, low-friction things like giving people an opening to send a quick tweet or FB post reaches a different audience than having a stand at the 'open science fair' or having a lecture open to the general public; those tend to self-select in the audience they attract, to put it mildly.
