If you watch closely in the liveleak video link - there is another cloud of smoke rising from the second explosion. After you hear it, the camera pans down the block for a split second and you can see it before they pan back to the first.

Yes, it's definitely disgusting!... and true... Though, I don't know that DHS is buying them it's sickening to think that anyone would.

These have since been taken off of the website since it started getting around, but it can be found in the cached form here (pictures have been deleted, but the ...

The snow is sticking to the nearly vertical panels pretty well! I'm gonna have to ponder this a little for my own system.

At least it's clear and sunny!

Chris,
I was up in Aberdeen a few years ago in mid-December. It was a surprise to only have ~6hrs of daylight, but then I realized that it was like being on the northern edge of the Canadian provinces.

Even I feel like I'm too far North for good solar. On the other hand, I have the world's largest ...

Hi Lars, welcome to the forum. Among other things, I do a little bit of casting too when the need arises.

Here are some some aluminum oil pans that I cast for a friend's Formula Atlantic race car. And a bad picture my crucible furnace made from a 55 gal. drum.

Cool! I'd be interested in seeing the action. It's a new chrome lined barrel, cheap at the time and I never expected too much out of it - always figured I could upgrade if I really liked the end product. I can't remember the twist rate, but I don't think it's optimal for the heavier bullets the ...

I've had one of these .50 BMG 'aircraft' barrels for... oh, about 20 years now. I think it's a M2 barrel, probably surplus from the 50's.

I originally designed a semi-auto action for it, but decided it was too big. And didn't really like the 'shell holder' type, so started leaning ...

That's kind of a cool looking clock. I'm not sure that I need another project, though.

The last few months I've been averaging 13kWh per day. That's after my initial crack at reducing my consumption by unplugging things that I don't need anyway, which cut it in half. And it doesn't effect the way I operate at all.

My plan as of now is to put in 32 245W panels and a single string of ...

It wouldn't be practical to do on a regular basis, but it's an interesting thought. I got started on that while looking at two parallel strings for the battery bank. Instead of running the whole bank as double the amp-hour capacity, I was thinking that you could alternate each half of the battery ...
