Humans emit heat on the order of a hundred watts and the only way to have that not affect the room temperture, is to "wash" it away in airflow with much higher energy content, as is typically done in clean-rooms. That still leaves you with the thermal radiation imbalance from the higher temperature of the human skin, which is why "nano" laboratories sometimes are kept at an uncomfortably warm temperatures. -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 p...@freebsd.org | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence. _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
