So.. we had some peacocks down by the barn.
A roadrunner saw the peacock, stared at him, then started bobbing his head up and down (a bird threat thing).
The peacock is about 5 times the size of the roadrunner. The peacock stands up, fans his tail, and vibrates it.
Roadrunner's eyes get really big. Turns tail and starts running with the peacock chasing after him.
Never did see that roadrunner in the barn again.
Hi Mikey, I didn't realize I was responding to you. A couple more reasons you might like:
- A Th/ brayton cycle plant would have a thermal efficiency of about 50% instead of the 30% or so you get from a U/carnot cycle.
- Because the primary is at 1 atm, you don't need a pressure vessel, which decreases the weight dramatically (Reactor pressure vessel is the heaviest thing on a sub.)
- Refueling turns into an RO and and ELT walking into the tunnel before a west-pac and pouring in a bucket of Th salts. The ELT is just there to smack the RO upside the head if he spills the salts.
These could increase shaft horsepower by 50% on a sub, while making operations substantially cheaper.
Adm Sestak tried to force the navy to build a LFTR when he was in congress, but unfortunately lost an election before he got his bill passed.
There is a good argument to be made for all civilian plants to be LFTR instead of U235 based:
- Thorium plants can't be turned into bombs
- About 4 times the amount of Th in the earths crust as uranium.
- Uranium plants mainly use U235, which is only .71% of natural uranium, so effectively there is about 500 times as much energy available from Th as there is from U
- Th can't be turned into Pu (or any transuranics)
- Transuranics are the long lived isotopes that require a Yucca mountain. Waste from a Th plant will decay quickly if not burned in the plant itself.
- LFTRs can be safely turned off by just cutting power and letting a salt plug melt causing a dump.
- Primary runs at 1 atm, so no high pressures to worry about. Grossly increases plant safety.
- No control rods necessary on a well designed LFTR, so reactivity excursions are not a safety concern.
I could go on...
I say that if you put it on the Internet, anybody can download and process it and then charged for the processed content. If you don't like it, don't put it on the public internet to begin with, or at least put in a robots.txt.
Google has web crawlers too. Everybody just got spoiled because advertising paid for google's crawlers and servers.
@eurofounder Can we get a an @IfindRetards for all the folks who don't understand comedy and sarcasm?

@CollinRugg Remember that the current Iraqi government is friendly with Iran. We don't want the same thing to happen in Venezuela.
If we just leave, the generals will probably get together and cozy up to China or Russia.
My favorite "It never happened story" is:
We were possibly someplace we weren't supposed to be. If you aren't there, you obviously can't pop up and run the diesel on a scram.
My only excuse is that I was dragging ass that week. Port and starboard RO's, because the lazy ass EWSs like 10 section watch rotations so they can sit in the goat locker and play poker. Dead tired and doing PPIP (primary plant instrumentation panel) weekly off watch. Lucky to get 4 hours sleep a day. Throw in low O2 on spec ops, and even caffeine won't do much to keep you awake.
No fancy digital stuff, not even those new-fangled transistor things. Our PPIPs were based off of mag-amps and LVDTs (linear variable differential transformers). I think they were all date stamped from the 1950's (594 class boat in the early '80s). A lot of hysteresis involved in valve sensors -- meaning if the sensor thinks something is closed and you drop back to neutral, the sensor will still say closed.
Anyhow, ultra quiet with the mains down and running shaft electrical on one TG (turbine generator). On and off RO (me) are getting pretty lazy on the phones. Finished one side valve checks. PPIP thinks loop valves are closed when they are actually open. I tell the On RO I'm done with the side and he clicks his phone, I start the other loop valve checks and then ... Bang. Scrams are surprisingly loud in machinery upper.
Adrenaline wakes me up for the first time all week. Scram recovery while making as little noise as possible. Cannot under any circumstances run the diesel ... so no pressure.
Frankly, we (both ROs) should have been DQ'd that day. But if they did that, we wouldn't be able to go from someplace we weren't to someplace we could be.
@VikingRobVWO Do just officers get to pull this crap? I can't imagine an enlisted guy on my boat (sub guy) pulling this without a captain's mast followed by a BCD.
