It would seem that given the estimate that it was in space for over 5 million years that it could be equally plausible that it came from another planet outside of our own solar system. Given the escape velocity needed for a rock to leave a planet's gravitational pull, an object traveling near that speed could travel quite a few light-years in 5 million years.

I have a dehumidifier that uses a large Peltier device, a couple of heatsinks, and a fan, I bought it off Amazon a couple years ago. It uses about 85 watts and removes around 150ml of water from the air in a typical day. It's not terribly efficient but it's very quiet and good enough to keep the humidity down in my small basement.

You make a good point that would be hard to disagree with and not look like fool, but going to the other extreme and denying the whole existence of ADD and ADHD (especially in countries where over diagnosing of it is not rampant as it is in USA) would be irresponsible as well.

I don't think there is much argument that ADD/ADHD are recognized and classified conditions. It's also obvious that the treatments do help those who have it, otherwise those treatments likely wouldn't be demanded by so many parents/teachers/doctors to try to help their kids. In the US, it seems far too common that we are too quick to diagnose ADD/ADHD and give treatment for symptoms when the underlying cause isn't ADHD at all but often bored kids with unfocused energy merely acting like energetic kids.

"That's just called being a kid!"

It's also called parents not parenting their children, which makes it very difficult for teachers to deal with these unparented kids in class. Drugs are a relatively easy band-aid for dealing the behavioral symptoms of kids that are raised by TVs, computers, and other gadgets rather than their parents (who were likely raised the same way). There may be huge, negative ramifications for dosing a significant percentage of an entire generation up to their eyeballs with meds in the foreseeable future.

Actually, a car traveling a constant 60mph is probably burning less fuel on a trip than a car going 0-10mph in stop and go traffic traveling over the same distance. Ideally it should take about 90 seconds to drive over the 520 bridge. Instead it takes between 5 and 30 minutes depending on what time of day you attempt to cross and what direct you go. Allowing cars move faster will ultimately reduce fuel consumption, which will reduce pollution. Everyone wins with more lanes.

I don't see why they want to take down the current 4 lane bridge and replace it with a 6 lane bridge. Eight or 10 lanes would do much more to alleviate congestion AND would still allow them to build their train tracks AND leave room for cars and busses. Heaven forbid that the regional economy picks up someday and there are more people commuting to and from Redmond and Seattle than there are today or tomorrow or ten years down the road. Otherwise, a year after the new bridge opens people will be complaining about congestion again and how this bridge needs to be removed and replaced with a larger bridge.

Originally, there were supposed to be both digital AND analog signals...

There have been both analog and digital signals in many markets since 1998, with the first nationwide digital broadcast being John Glenn's return to orbit on the space shuttle. From that point more and more stations began to offer both analog and digital signals, now it's time to turn off the analog.

What issue of Popular Mechanices were some of these proposed? I'd like to read it. These proposals were from the book, "Omega - Murder of the Eco-system and the Suicide of Man" published in 1971. I'm still not sure how Iraq and space elevators fit into the equation though. The earliest serious proposal I found was from the November 1968 "Bulletin of the Atomic Scientists" where it details sucesses of Soviet scientists in decreasing the albedo of arctic glaciers by intentionally covering them up as a way to trap heat.
New York Times, August 14, 1975:

"With many signs today pointing to the possibility that the earth may be headed for another ice age, minor or major...there is suddenly renewed interest within the scientific community for some sort of monitoring of the sun's input.

Peter Gwynne, Newsweek April 28, 1975:

The evidence in support of these predictions has now begun to accumulate so massively that meteorologists are hard-pressed to keep up with it....The central fact is that after three-quarters of a century of extraordinarily mild conditions, the earth's climate seems to be cooling down. Meteorologists disagree about the cause and extent of the cooling trend, as well as over its specific impact on local weather conditions. But they are almost unanimous in the view that the trend will reduce agricultural productivity for the rest of the century.

Science, March 1, 1975:

According to the academy [National Academy of Sciences] report on climate, we may be approaching the end of a major interglacial cycle, with the approach of a full-blown 10,000-year ice age a real possibility. Again, this transition would involve only a small change of global temperature--two or three degrees--but the impact on civilization would be catastrophic. Scientists once thought the onset of an ice age would be very gradual, with glaciers slowly pushing down from the North, but recent studies...indicate the transition can be rather sudden--a matter of centuries--with ice packs building up relatively quickly from local snowfall that ceases to melt from winter to winter.

In the 70s there was serious talk about massive geo-engineering projects to stabilize the climate.

One of the largest projects proposed was to create seas in Africa. If the Congo, which carries some 1,200 cubic kilometers of water per year, was dammed at Stanley Canyon (about 1 mile wide), it would impound an enormous lake (the Congo Sea). The Ubangi, a tributary of the Congo, could then flow to the north-west, joining the Chari and flowing into Lake Chad, which would grow to enormous size (over 1 million square kilometers). This large lake (the Chad Sea) would approximately equal the combined areas of the Baltic Sea, White Sea, Black Sea, and Caspian Sea.

Another proposal was to create a Bering Strait dam which would increase the inflow of warm Atlantic water by stopping or even reversing the present northward flow of colder Pacific water through the Bering Strait. The proposed dam would be 50 miles long and 150 feet high.

Also huge dams were proposed between Florida and Cuba and in the Tatarsk Strait (near Japan) to disrupt and deflect the Gulf Stream and Kuroshio Current, which would circulate warmer water to the north.

All of these proposals were presented as necessary to prevent the impending ice age. If these scientists had their way back then we'd be roasting right now. Now if we let these same people try their new plans now that the "consensus" has turned 180 degrees we'll probably be equally screwed a few decades later.
