Well, extraordinary claims need extraordinary proof, and where things like this usually fall apart is difficulty with replication

As of this morning, there are (as yet not really verified) reports of replication from the Huazhong University of Science and Technology in China

a team at the Shenyang National Laboratory for Materials Science, and the other is from Sinéad Griffin at Lawrence Berkeley [both] come to very similar [theoretical] conclusions: it could work.

I am guardedly optimistic at this point. I await more replication data
