The cop did not choke him -- this leaves a mark every time. He died of a heart attack. Were the cops guilty of brutality. Yes. Every takedown is brutal AFAIAC. I don't know if this met the legal definition of police brutality and neither do anyone else. But they did not choke him.

The law was brutal because NYC has to make sure they collect very high tobacco taxes

War has never been the real way to depopulate the earth, grand total deaths through history due to war are likely less than 500 million. The bubonic plague aka black death is credited with killing off 1/3 to 1/2 of the population in Europe and Chine -- much more effective

Of course, we have better ways to kill lots people these days, just a few EMP's weapons could kill billions as civilization collapses. A single truly nasty bio-weapon release -- airborn smallpox or ebola could do the same with direct deaths as well as collapse.

You are not pulling heat out of the atmosphere. More accurately you are pulling heat out of the atmosphere then re-releasing the heat into the atmosphere as the generated electricity or mechanical energy is used. You are simply not introducing additional heat into the atmosphere by not burning coal or splitting atoms, etc.

However, heating the earth's atmosphere via energy generation is negligible. Total earth energy consumption is about 15 terawatts, total earth solar irradiance is about 173,000 terawatts. This raises the global mean temperature by about 0.0065 degrees C

Nonsense, congress could pass changes that emasculate the FCC in this regard. Certainly the current POTUS would doubtless veto, but the next one might not.

Likelihood of such a restriction on the FCC is another question, and I would guess fairly improbable. Should this regulation become very unpopular, then it would be likely to be overturned by congress.

Comment Re:Chemical weapons are much older than 100 years (Score 1) 224

Greek fire is often thought to include calcium oxide a.k.a. quicklime. This is caustic and has been used as chemical weapon by itself. That is why I originally said it was arguably a chemical weapon though the primary effectiveness is clearly as an incendiary. Primarily I included as a reference because it is more more widely recognized as being used in warfare. The pure chemical weapons go back a long time -- far predating greek fire.

Greek fire is arguably a chemical weapon and well known.

National Geographic has a nice article about the long history of chemical (and biological) weapons,

The real difference in the modern era, it has become an economical form of warfare as well as more effective (higher rate of casualties) than older chemical attacks.

Comment Re:Why just fossils? Maybe organics too. (Score 1) 88

I don't know, if you have a comet or asteroid impact big enough to eject material into space you have to consider that the ejecta is going to be heated by a large amount. Much of the "ejecta" is in the form of vaporized rock, much of the solid ejecta will be fractured. The fireball associated with an impact of this size is also going to be large (10's or 100's of km in diameter), so you get additional heating beyond the heating of atmospheric compression while the ejecta is departing.

Seems like organics would be unlikely to survive the trip most of the time.

The slower eject will not be generally be heated as much, but you won't find those on the moon.

Buckyballs were targeted by the government -- Consumer Product Safety Commission (CPSC), so people tend to assume they were unusually risky. According to the CPSC, 22 kids have been injured, no fatalities.

Bicycles, skateboards, and trampolines -- all much higher risk. Yet, no-one is proposing banning them, because we are used to the risks.

A few grams of radioactives, as providing with the toy, essentially no risk of significant unless you consume them.or use them as an eye patch.
