We get deluged with questions here at Private Briefing. And it's no surprise to me that the bulk of them are excellent queries. We answer them in different ways ... some by writing back to the subscriber ... and some as secondary topics in the daily column.
Many of your questions - like the dozens of requests we recently received about graphene - lead to actual recommendations or even special reports. Other queries will form the basis of "roundup-style" Q&As with our band of experts.
Every once in a while, however, we'll get a question that's so good, or that's so representative of other queries that we're getting, that it deserves a standalone answer.
