There's a bigger problem at play here I think, and it's a variant of the CSI Effect.
It appears large swaths of people are getting knowledge of the sciences from popular entertainment. Of course they do impossible things all the time in fiction, but too many people seemingly can't distinguish the impossible things from the possible, so we end up with jurors that think "DNA" is the answer to every crime scene question, and people thinking "nanotech" can recreate magic.
I'm not sure how to fix this. The long term effects of devaluing knowledge scares me, though.
not really a practical thing (maybe some day, maybe never) - anything can be an antenna, not necessarily a good one, especially if you want some output actual power
