dormitories for the 50% of workers made redundant by automation around 2050. Would like to get it into the book if I had a reference. Note the use of a time in the future to stay near topic. Bill Hawkins ___ time-nuts mailing list -- time-nuts@febo.com

Re: [time-nuts] 60Hz extra PPS: got one

changed for more A/C load. I expect you'd rather do things in software, but the mechanical solution is to couple a synchronous motor to a flywheel marked with 60 Hz lines for photocell pickup. A precision 33 1/3 rpm turntable with strobe markings would work very well. Bill Hawkins -Original

Re: [time-nuts] Leap second? Yay or nay?

may be viewed directly when local time does not matter. It works for trending analog process data in manufacturing plants that observe seasonal time (not all US states do). Bill Hawkins P.S. During the manufactured oil crisis of 1974, that started us on the path to multinational corps
