You misunderstood me. Just open the breaker. You'll still have a customer charge of $18/month or so but it seems to me that the trouble starts when you tell the electric company that you don't want to be a customer. Unless you're trying to tell me that there's a legal consequence to having zero consumption on your power bill.

I don't know where you buy your electric power but here (PA) the choices I can make for electric supply have a wide price range. I can choose cheap, in which case my electricity is likely to come from coal-powered plants, or I can choose green (wind/solar/biomass) in which case I pay a higher rate. Specifically, my power choices range from 6.91 cents/kwh to 13 cents/kwh on fixed-price contracts.

I'm also not "forced" to select - if I don't choose I end up buying from Met-Ed, the distributing utility.

For those too young to remember, Commander Keen was a series of shareware 2D platform games for the PC released by Apogee Software (aka 3D Realms) developed by no less than id Software — the developers of Wolfenstein 3D, Doom and Quake."

Except you obviously missed the section labeled "Features" in which it says Autonomous Detection/Tracking/Targeting and Manual/Autonomous Firing with Safety

I'm not seeing that in the article or in the poster. The DODAAM website is slashdotted right now, but if it says that I'd be suspecting a bad translation. There's nothing in the feature set of this piece of hardware that supports automatic tracking or autonomous firing. Detecting a human size target at some distance only means the optics and camera has a certain minimum resolution.

I've actually done some work on integrating a similar US-designed device onto a semi-autonomous vehicle, so I can read the DODAAM poster with some background.

Building a Telegraph Using Only Stone Age Materials 238

MMBK writes "It's the ultimate salvagepunk experiment, building a telegraph out of things found in the woods. From the article: 'During the summer of 2009, artist Jamie O’Shea of the organization Substitute Materials set out to test whether or not electronic communication could have been built at any time in history with the proper knowledge, and with only tools and materials found in the wilderness of New Jersey.'"

The whole notion that some body that is on the other side of the sun from us half the time is protecting us doesn't really work in my mind. It seems that it only works if you imagine the universe is laid out on a line. Put the Sun at zero, the Earth at 3 and Jupiter at 10 and then anything heading your way from >11 has to get past Jupiter first. In reality we can't even rely on foreign objects coming in along the ecliptic.
