Overheard in the Office:

Me: Huh. That's interesting.

RX: What's interesting?

Me: Urea-powered fuel cells.

RX: Piss on that!

If you think that idea will work, urine for a big surprise.

And just when I'd learned the difference between #1 and #2 diesel, too.

Have you seen the new diesels with the DEF tanks? It is a tank for an additive called Diesel Emission Fluid. They have discovered that if they run the exhaust of a diesel engine through this stuff, they can reclaim the unused diesel and cycle it back into the engine making everything run cleaner and more efficiently. Several of the truck stops are putting in dispensers in the truck lanes.
Why is this relevant? DEF is urea.

Actaully, DEF does not reclaim unused diesel. When heated the urea is converted to ammonia and the ammonia reacts with nitrogen oxides (NOx) in the exhaust, producing plain nitrogen and water vapor. See http://www.fleetguard.com/pdfs/product_lit/americas_brochures/MB10033.pdf (for instance).

DEF is mandated by the EPA for use in all 2010 and following diesel engines. And it makes diesel engines cost between $8-$9,000 more per pop.

Just another unfunded government mandate forced on industry.
