Green wire

Maybe too much time on my hands, but.....
In house wiring, why is the Green wire usually the same gauge as the current-carrying wires?
The green should never have current, right? So why don't they save copper and make it a smaller gauge?

Re: I-Phone to flat screen with HDMI

Cool! But no audio to the TV, right? Audio stays on your device, i.e., phone, iPad, etc.?

Re: Wood, some of the best stuff for music

Very cool! Often thought of sticking a couple of probes in a tree to "listen" in on impulses that surely exist. Or ground probes.
Anybody ever try that?

Re: Citizens band (CB) Radio: Who still uses it?

In the late 60's, I spent a good piece of a paycheck on two 1-watt handheld, 2 channels CB walkies. Got over 3 miles range in the almost-noise-free environment of southeast Asia. Got a half-mile in western New York due to the heavy electrical traffic. That with a 4 foot long telescoping antenna. Goo...

Re: Of some interest!

Indeed, wood dust/chips have been used to vary the properties of concrete!

As for that wire stripper, might contract with a local metal recycler to strip the miles of insulated wire they get in.

Re: Energy problem solved!

You're on the right track dacflyer! Dunno about your locality, but up here in the dreary north, I'm thinking dollar-for-dollar that I may be better off with a wind generator rather than solar. 24/7 when the wind blows, which is almost always.

Voice-operated winch

Any simple voice-activated relay closure circuits out there? Mounted an electric winch on the lawn tractor to raise and lower the snowplow. With steering, throttle, and push buttons to raise or lower plow, I run out of hands. Looking for a microphone and voice commands to close contacts from the com...

Re: Anyone here ever mess with UPS's ( back up power supplies )

Add an autotransformer (Variac) to get your 120 VAC.
Probably more trouble than the UPS's are worth.
