Water Clocks
Remember that Jim Croce song about saving “time in a bottle?” The Ancient Greeks had something like this centuries before 1973. One of the earliest types of timekeeping device, the Ancient Greek clepsydra used the flow of water to measure the passage of time. Clepsydras used either intake or outtake methods … water filling a container or water emptying from a container … to measure time. Unfortunately, clepsydras were not portable. In fact, disturbing the clocks in any way messed up the timekeeping.

Dacey,
it's a handsome photograph, I'll give it that, but for now I'd rather date women, thanks.

#9 Tesla fanboys will believe anything. That idea of electricity through the air is dangerous and so busted.

You're assuming that all frequencies of microwave radiation are dangerous. Tesla lived to a 86 years, despite his exposure to it. Cell phone towers use microwave frequencies.
