Avg whole body SAR limit they use is .08W/kg. For reference, IEC 60601 governs the SAR limit for MRIs at 2-10W/kg [1]. Also, FCC limits cell phones to 1.6W/kg

- Gravityloss 10y agoYou could also heat humans, much more energy efficient than heating the whole apartment or house. Though it would heat any water or fat lying around.
- mirimir 10y agoIt's an old idea: https://www.newscientist.com/article/mg15220615-500-not-cooking-but-warming-serious-researchers-are-turning-themselves-into-living-radiators-by-walking-into-giant-microwave-ovens-pete-moore-wonders-why/ https://www.newscientist.com/article/mg15220615-500-not-cook... very far infrared == very short microwave
- Gravityloss 10y agoHmm, didn't think of it like that. Although most things are indeed quite reflective in the infrared. You should choose a frequency that humans would absorb, but walls and furniture etc would reflect. Or you would need to buy "certified microwave non-absorbing" wares only for such rooms.
- mirimir 10y agoThe idea was to use very high frequency microwaves, so that only skin surface was heated.
- jacquesm 10y agoI wonder what your DNA integrity check has to say about that after a couple of years of exposure.
- mirimir 10y agoThat's probably why it's never gone past "hey, why not..." since the 70s ;) On the other hand, the outer ~0.03 mm is dead. So ???
- hinkley 10y agoI thought the problem was that this also heats ocular fluid and furniture staples causing potential problems with things like macular degeneration or house fires, respectively.
- mirimir 10y agoIf the penetration depth is << 1 mm, I can't imagine that ocular heating would be an issue. And I'd expect that power levels would be too low to heat metal. But maybe so.
- sandworm101 10y agoBut any sparks from the metal coulf cause fires. Not much power needed for a spark.
- rm_-rf_slash 10y agoIt was also a joke on the first season finale of Silicon Valley.
- tekromancr 10y agoI remember seeing that and thinking it was actually a solid idea

- taberiand 10y agoWasn't that a thing on Silicon Valley (the TV show)?
