Ok, so we've isolated the compound. Why do we need the Pandas now?

can you not otherwise impart enough heat to flash boil the water? Why not a big metallic thermal load, made out of recycled popcans?

I believe the trick here is that because you're injecting the "fuel" (liquid water) and injecting the heat source you are able to very precisely control the timing of the engine as well as control the steam's wave front. If you had a static heat source inside the engine there's not only the question of how you deliver heat to that, but also how you control triggering of the phase change.

Also separating oil and water is easy, seeing as they don't actually mix.

The oil is assuredly atomized to increase surface area and heat transfer, seeing as the timing of such an engine depends on precise (and rapid) water phase change. Much like a diesel engine you're relying on very precise injection timing and predictably fast burning/expansion.

A oil/water mixture composed of such tiny droplets is not trivial to separate.

Separating oil and water which have been mixed at such a fine level doesn't seem the easiest. While I know it can be done, can it be done in such a manner to maintain any of the heat energy which remains? Or does one just accept that energy as lost?

What has slashdot become? Terrible. This is supposed to be "News for Nerds. Stuff that Matters."

What part of the quants invading sports and demonstrating that brains can win over brawn in the physical arena isn't news for nerds?

Require? No. Able to use? Yes.

Or an original xbox with xbmc. But it struggles with > 720

That's because the original X-box is about the slowest hardware anyone runs XBMC on.

XBMC does 1080 just fine.

The drivers for hardware decoding on the Apple TV2 are very good. 1080p (downscaled) and 720p play perfectly with XBMC on a jailbroken ATV2.

That is assuming they are encoded with x/h264. MPEG4 ASP plays fine SD but only marginal HD, and that's because the CPU is slow.

The question is, why should someone with low income but fully owned property NOT be allowed to live in it?

Because real estate is special. All real estate is owned by individuals through patent by the government. The point of real estate is to benefit society as a whole through development and wealth creation. Property taxes are a purposeful disincentive on "sitting" on a piece of valuable property.

Why isn't Creative's Zen line supported?

Because nobody who has a Zen has stepped up.

AMS gave datasheets. http://www.rockbox.org/wiki/AustriaMicrosystems

Sandisk gave dev boards and NO docs.

Nobody else gave squat.

To be pedantic WAAS is a differential system.

And to be overly pedantic for the GP, WAAS specifications don't meet the 1m/24/7 spec, but in practice it is sub meter 95% of the time.

Your vendor is likely confusing you (and perhaps themselves).

GPS horizontal positioning does not require a very precise model of the earth.

GPS vertical positioning does not require a very precise model of the earth.

The gotcha there is that GPS works in ellipsoidal heights, NOT elevation. The ellipsoid is a simplified model of the earth. Elevation is height above mean sea level if the sea reached where you are. The elevation of any point measured by GPS is a combination of the ellipsoidal height and a gravity map (if there were no land, no wind, no tides the sea would still be uneven due to uneven distribution of gravity potential) called a geoid model.

As for lock and initialization times - I routinely profile roads, in traffic, and have no trouble maintaining initialization. That and a Trimble R8 GNSS (R8 model III) can initialize FAR faster than 20 seconds.

Close.

Carrier tracking does not require a very precise model of the earth. Real Time Kinnematic GPS has been done for well over a decade with rather sane processing requirements. It also isn't unstable. So long as the L1 and L2 signal of five satellites are tracked one can initialize on the fly, and you only need to track four continuously to maintain said initialization.

Like differential (a code-base correction) kinnematic requires a base receiver and a rover receiver. They can either be in real time contact or the results can be post-processed. Differential and kinnematic both work by estimating the ionospheric delays, the difference is between tracking the long-period time code or tracking the short-period (19cm) carrier wave.

The problem isn't the GPS system. The problem is John Deere is trying to use the system at an accuracy (100% availability at 1m) greater than the specified [civilian] performance levels (95% availability at 7m).

While I can't speak as to the John Deere system in particular, most the Ag navigation systems are using WAAS on the low end and VRS RTK subscription systems on the high end.

Here in Ohio ODOT offers a reduced-fee reduced-accuracy VRS option for farmers, who don't need the sub-cm service.
