Comment Re:Two questions need to be asked (Score 1) 546

"Comrades," he said quietly, "do you know who is responsible for this? Do
you know the enemy who has come in the night and overthrown our windmill?
SNOWDEN!" he suddenly roared in a voice of thunder. "Snowden has done
this thing! In sheer malignity, thinking to set back our plans and avenge
himself for his ignominious expulsion, this traitor has crept here under
cover of night and destroyed our work of nearly a year.

Comment Re:Cancer vs common cold (Score 1) 52

Fighting cancer is fighting evolution itself.

Your body is composed of some 40 trillion cells. Each one comes from a line of cells going back billions of generations, every one of which succeeded in reproducing and projecting itself into the future. DNA is not easily squelched.

Comment Re:Hmmm ... (Score 1) 167

The specs on that unit give some idea of what's possible with a miniature peltier dehumidifier:

Weight: 3-1/2 pounds
Rate: 8 oz per day at 80% RH
Power: 22.5 W

That's a lot of weight, and it would take quite a bit of solar panel to get that much power. And all that for a thimble-full of water in an hour's ride.

Comment Re:To Kill literacy (Score 3, Insightful) 410

Libraries are not, and cannot be, archival repositories of books. A library uses its fixed resources (in money, personnel, and space) to house a collection which is useful to its patrons. It's silly to complain about a library discarding books. How else would they have room for anything new? The librarians and administrators are the ones responsible for choosing and maintaining the collection. That's their call. If you think the collection should move in a different direction, send a letter to the librarian--you'll probably be pleasantly surprised with a coherent and reasoned response. This "outrage" is just dumb.

Comment Re:Is Hydrogen more dangerous than other gasses? (Score 2) 479

Does hydrogen have a lower flashpoint or some other quality which makes it more dangerous?

Limits for hydrogen leaks that can support stable flames, International Journal of Hydrogen Energy Volume 34, Issue 12, June 2009, Pages 5174–5182

Hydrogen is an unusual fuel. It has a high leak propensity and wide flammability limits, 4–75% by volume. Among all fuels, hydrogen has the lowest molecular weight, the lowest quenching distance (0.51 mm), the smallest ignition energy in air (28 mJ), the lowest auto-ignition temperature by
a heated air jet (640C), the highest laminar burning velocity in air (2.91 m/s), and the highest heat of combustion (119.9 kJ/g). Hydrogen flames are the dimmest of any fuel. Hydrogen embrittles and attacks metals more than any other fuel.

Mind you, this is from researchers generally inclined towards the use of hydrogen.
