Maybe you could spiral the Magrid power and return lines in the supports instead of adding "loops". I think I talked about this somewhere else not so long ago for the Magrid itself.

Yup, and I bet it would make a nice expensive lamp as well.

How does ISS remove internal heat? Honest question, I know it is an issue, but have not stopped to see how they actually sched heat from inside. The average person gives off about 100W as I recall, and each operating piece of equipment adds in. I know from personal experience that it gets REALLY FRE...

No one ever said a heat engine had to involve heat transfer across a boundary as an essential operating principle. MIT does. Georgio - thanks, you summarized well. These were the thoughts rolling around my head last night and this morning after my last post. It was what I was starting to get at abo...

And that is the rub. IC is not Carnot, it is Otto. Some argue that ICE are not a heat engine because it is not a bounded system nor reversable process. Semantics to be sure. I still think the classic definition of a heat engine does not fit, however I do concede that it can be plotted on a PV curve ...

Found another funny thing today, EMC2 got gigged for the feb-sep 2009 cycle for significant reporting errors in the recovery.gov report submission.

Did the page help? You can go through the whole semester's notes if you wish, but I think it is captured well enough here, and you have the background not to need the fundamentals discussed in the previous sections.

I thought he was talking about the inner grid only.

But yes, I should have specified the magnetic sheilding (Ma) as well in the construct.

I thought ETW still had two grids.

See page 45 of Fusion Power vol 22, 1992 Section III B, of Krall's article that talks about ion spherical convergence and the dense core as they understood it then. It is suppossed to be a function of machine radius (magrid), ion birth energy, well depth which in turn drives the angular turn rate at...

It is a process (cycle), that is what makes it solvable. You have attempted to apply the Ideal Carnot Cycle efficiency equation, but this does not apply to an Ideal Otto Cycle. You also did not identify the process points from the Carnot PV diagram to an ICE, which you will find does not recognize t...

30 July is next update for sure...

from recovery.gov;
The reporting cycle for Quarter 2, 2010 (April 1 - June 30) began on July 1 and will run through July 20. Reports received after July 14 will be marked as late. Quarter 2 data will be posted on Recovery.gov on July 30.

Although the Carnot cycle is theoretically the most efficient it is in no way a practical device. Also the energy transfers would be far too slow for any real benefits to be realised. Internal combustion engines work on non cyclic processes because the fuel-air mix enters the system and products of...

But, it is the introduction of a high temperature gas to the container(cylinder) Just like a steam engine. Except the hot gas is BURNED in the cylinder and not a boiler. Ever read a college level thermo book? Yes, and been graded, have you? So please again, tell me how the gas fluid igniting in the...
