Diamonds Are a Fuel Cell's Best Friend
Roland Piquepaille writes "Researchers at UC Davis have used nanocrystals made of diamond-like cubic zirconia to develop cooler fuel cells. Even if hydrogen fuel cells have been touted as clean energy sources, current fuel cells have to run at high temperatures of up to 1,000 C. This new technology will allow fuel cells to run at much lower temperatures, between 50 and 100 C. Obviously, this could lead to a widespread use of fuel cells, which could become a realistic alternative power source for vehicles. The researchers have applied for a patent for their technology, but don't tell when fuel cells based on their work are about to appear."
Diamonds are not a good investment... actually, not an investment at all.
"Honey, stop wasting our money". That's basically the gist of it.
"But you don't care about me if you don't buy me a diamond ring"... well, sorry babe, I expect a life partner WITH a functioning brain, able to process facts.
Gold ring, platinum ring, stuff like that, sure, why not.
But diamond rings? HELL NO. You won't see me buying something like that, ever.
By reading this signature you agree to not disagree with the post you just read.
You mean, able to process facts like living in a society which places enormous social value on receiving a diamond ring? That the value of diamonds is not an accurate reflection of their inherent scarcity does not change the value of diamonds.
Or, put another way, gold and platinum are just about as arbitrarily valued as diamonds. Gold in particular, as it's a specifically unsuitable metal for an item one intends to wear on a finger for one's entire life. It's about as undurable as one could hope for.
You, obviously, are free to take a principled stand on any issue you wish to. But it's not accurate to claim that anyone who wants a diamond ring is necessarily ignorant of facts. That person may just not weight the "true" economic value of a diamond over the social value of a diamond to the same extent you do.
Reality has a conservative bias: it conserves mass, energy, momentum...
I presented the following offer to my wife: Diamond Ring...Or a House. I cannot afford both. Choose wisely.
She did. I am blessed with a wife only wanted a silver band.
I am not the typical Slashdotter though. I am probably a 1-percenter (married, kids, hobbies outside of computers)
