True, those tiny countries with generally homogenous populations have a smaller proportion of people living in poverty. Japan and Germany, on the other hand, are very similar to the US (16% and 15.5% respectively, compared to 15.1% for the US).

Flammable (or explosive) range is the range of vapor concentration that will burn or explode in the presence of a source of ignition. Below the range, there's not enough fuel in the mix to support ignition; above the range, there's not enough oxygen. The range (in percent) for hydrogen is 4 to 75; for gasoline, 1.4 to 7.6. While it's true that hydrogen won't hang around in puddles waiting to be burned, it's much more likely to be touched off in the first place.

...being considered a troll on Groklaw is more a badge of honor than an insult these days.
