I highly recommend the Naval Undersea Museum in Keyport, Washington. (Well only if you are into technology) There is a fair bit of history on display there. More than just weapons. http://www.navalunderseamuseum.org/

I forgot, here is write up on the Howell torpedo. http://www.navalunderseamuseum.org/media/6c06204b6731dd48ffff8332ffffe906.pdf

Snow?

My first computer required that you toggle in the boot loader binary code from front panel switches!

That has to be the modern equivalent of hand crank started horseless carriages.

Takes me back to loading those Interdata model 3s with the front buttons so we could load the paper tape. Then we could watch the registers with lights on the front as our code executed. Ah glad those days are over.

Good luck going to Safeway and buying your Jeno's frozen pizza with Euros, Yuan, or Yen, but they're all "real" money.

And if you're at safeway in australia good luck paying for it with US dollars.

In my earlier days, when I worked at Safeway in Washington State we were happy to take Canadian money, so we (either the U.S. or Safeway) used be somewhat flexible. I bet the manager would have taken Euros too if they had existed at the time. (But may be not at the best exchange rate.)

He's a figurehead and a spokesperson at big events, but ultimately is only as good as his advisors and staff. He can't be at every interview for coders, or even interviews for the HR people who hire the coders. He has to trust his staff to do their job, and they didn't. I see this as more of a marketing selling an idea up the food chain, and dev trying their best to hold it together while sticking to their ridiculous deadlines. The next CEO will be in exactly the same position, because everyone else responsible is still in their position of responsibility.

If they are just figureheads, then why are they paid such a high salary. They do well when things out of their control go well, they are punished when things out of their control go wrong.

For the folks who don't know, we are talking about plutonium 238. This has a half live of 88 years so decays rapidly and produces a fair amount of heat. Using thermocouples this can be used to generate power with no moving parts. The decay route is alpha particles which are fairly easy to shield against. Your favorite bomb material plutonium 239 has a half life of 24000 years which leaves it safer to handle but not useful for thermoelectric generation

There is a fair amount of nitrogen compounds in coal. At the lower combustion temperatures of chemical looping most of this will not be converted to NOx, but will still need to be removed from the combustion gas stream if your planing on a CO2 sequestration pipeline. Turns out the nitrogen does not compress to a dense phase as well as CO2, so you will probably need to remove it. This is another problem of the proposed oxy-fuel combustion systems.

There are many labs working on chemical looping combustion. Most have not gotten to "burning" coal yet. They are starting with natural gas to prove the process. Usually they will use two to three fluidized bed beds reactors to convert the fuel and oxygen (from the air) to CO2 and water. The trick, as I see it, is to find/develop, the oxygen carrier. Most so far have been Fe, Mn, or Cu based. Raw minerals have been tried for the carrier but they break down, both from attrition and from the chemical conversion of adding and losing the oxygen. You might get 20 loops out the material before you lose the material in the cyclone separators. They have also tried the putting the oxygen carrier on ceramic carriers. This seems to survive longer, but the cost is higher. The models I have seen suggest that if you need to sequester CO2 and you are burning coal this has real economic advantages over oxy-fuel combustion or integrated gasification combined cycle power systems. Then if you are going to move the CO2 any distance you will still need to clean up and dry the CO2 stream if you are going to pipeline it, but while we continue to use fossil fuels we need to be smart how we use it.

Well, judging from the project data sheet for Yuasa batteries (guessing the front and rear ones are similar) the LPV 10 and 65 http://www.s399157097.onlinehome.us/SpecSheets/LVP10-65.pdf, and MSDS of http://www.gsyuasa-lp.com/download/file/fid/112 use a organic solvent (mixture of alkylcarbonate solvents). (like ethylene carbonate http://en.wikipedia.org/wiki/Ethylene_carbonate) and that stuff should be solid at room temperature. I wonder how it leaked through the bottom of the battery compartment of the Japan 787? The info does suggest it will burn if you get it hot enough.
