Whatever, dude.
Efficiency is based on differences in energy that are economically accessible, not on some rambling theories in a newline-free paragraph.
You can access room temperature. You can' economically access the blackness of outer space from the earth's surface. Likewise, you can access the negative terminal on your battery, but not some static charge in the upper atmosphere.
You pump X amount of energy into a heat engine, it expels that energy to an accessible exhaust, and typically 70 to 95 percent of that energy is *not* converted to work. You pump X amount of energy into a battery, it dumps that energy through a motor to its negative terminal, and only 5 to 10 percent of that energy is not converted to work. That's the only way to practically analyze the situation.
We could also all have infinite free energy if we could access the levels below the zero point energy in the quantum fields. One little problem: that's not accessible either.
cosmic rays are what you blame when you can't find the bug
Sometimes you can prove it was a bit flip [caused by cosmic ray, local radioactivity or a glitch in the Matrix], you just need to find the exact bit. A friend of that managed to do exactly that after an error in his monthly accounting software. He proved you could only get the resulting sum if you flipped bit Nth of a certain value during the summation. It took him a while and he had written the software himself.
For the example in TFS of 200F water and assuming room temperature exhaust, Mr. Carnot says that the max possible efficiency is less than 20%. Any real world engine, including this one, probably ends up at a low-to-mid single digit percent efficiency. IOW, the vast majority of the heat would still be wasted.
The operator of the facility generating the waste heat might get more energy savings at lower cost by tweaking their processes to be a few percent more efficient in the first place, instead of trying to recover this low-grade energy source with an elaborate engine and plumbing.
Once you import numpy, Python has arrays.
Would be cool if they could make an in-home or in-gym/office MRI so that you can scan yourself every few months looking for deltas
That would never fly. You just know that some dufus at the gym would bring a 10kg steel dumbbell into the MRI room and ruin things for everyone.
Kids should be given REAL computers, like apple II's or commodore PET's to study on.
They tried, but quarreling parent groups couldn't agree on whether to teach the kids that they were coding with 3 registers or 259 registers.
Before NT, Windows was an absolute mess. I think the only reason most people put up with it was that they didn't know anything better was possible and since Windows was so widespread it was a misery everyone shared.
I think that many of those people were also recent DOS users. Given that DOS systems would often simply freeze up several times per day and require a reboot (easy to do since any bug in the user's application could do this), once they added a protected mode pseudo-kernel to Windows (maybe starting with Windows/386 2.1), it was actually a slight improvement over what they were used to since DOS crashes could sometimes be isolated to one virtual terminal.
It's because it's very difficult to imagine circumstances other than what we live in. I agree with what you're saying in general but only in general. Plenty of liberals live in small towns and plenty of conservatives live in big cities.
But a LOT of liberals have only ever lived in a big city and a lot of conservatives have only ever lived in rural areas. And for those people, a move is transformative
For the conservative, the idea that government can do anything useful seems insane. But move to a big city where government services form the backbone of your water, sewer, mass transit, snow removal, etc and it's really hard to look at government and say it can't do anything right. Government somehow keeps Chicago clear of snow. Like -- really think about that. That's an ongoing and ENORMOUS project and it goes off largely without a hitch. It's difficult to see that in person and really say "government can't do anything right."
For the liberal, the opposite is true. They've spent their life surrounded by largely competent government. They move to small town America and suddenly the entire local government is run via the good-ol-boys network. Distance makes it all but impossible to actually get services to the people who need them. Taxes seem like they take a lot out of your pocket and don't put much back.
The problem is that our votes -- especially at the national level -- govern both groups.
But I was told that the sole reason insurance rates are high is because of BIDEN!!!!1!
Recursion is the root of computation since it trades description for time.
