E = (T2-T1) / T1

Everyone with an engineering degree knows this. Trying to extract much energy from low-grade heat at the output end of an engine is inefficient. This was figured out a long time ago. Here it is in The Manual of the Steam Engine. It's possible to increase steam engine efficiency by compounding, where the exhaust from each cylinder feeds a larger, lower pressure cylinder. This is cost-effective up to about 3 cylinders ("triple expansion"). Engines up to quintuple-expansion have been built, but the additional power from the last two cylinders in the chain isn't worth the trouble.

In 2005, this appeared in SF Weekly, about the gentrification of the Polk St. area of the Tenderloin:

Gay Shame calls the Lower Polk Neighbors Association a "brutal gentrification squad" of wealthy business owners, slumlords and bureaucrats.

"They are trying to transform Polk Street from the city's last remaining gathering place for marginalized queers and street culture into a hip destination for wealthy suburbanites," Mary said. "We want a safe place for marginalized people, and Polk Street has historically been that space.

"The neighborhood may soon be known more for green-apple mojitos and stretch Hummers than trannies and tweakers (methamphetamine users)."

That was back in 2005. Gentrification won.

His antipathy towards our most important civil right, the right to self defense, shows that Stevens was never fit to be admitted to the bar at all. The second amendment doesn't need fixing, it needs ENFORCEMENT.

The right to keep and bear arms isn't for the government to grant or withhold, and the second amendment doesn't even presume to do so. It acknowledges the right as pre-existing, it cites one important reason for preserving it, and forbids the government from infringing it.

Never encountered that in school, but by 9th grade I already knew what kind of damage you could do to someone if you knew their name, address and SSN.

Instead of referring to a fiction novel, you could just refer to a book called "None Dare Call it Conspiracy" by Gary Allen which is non-fiction and contains thousands of references. I realize that the title contains the word "Conspiracy" and people have been brain washed into believing "conspiracy == false|insane|crazy", but it's an exceptional book that woke many of us up in the 1970s. I don't know about any of the re-released versions, so suggest you start with the first book. You can read the book for free here.

Do you think that the public will be made aware of this study and be exposed to dialogue regarding the study? I find it much more likely that the media will instead continue to attempt to distract US citizens with more celebrity and sports news and other fake "News" designed to distort reality. It is important to remember that the same people running the Oligarchy also own all of the FCC broadcasting licenses, Newspapers, and TV studios.

Yeah, I used to just blame all of the people for being ignorant fools. The more I studied the monopolization of media and 'News' (both broadcast and print) the less I could blame people who are intentionally mislead and given almost zero real information. Don't take that as blaming journalists, because there are still a great many real journalists in the US. They receive no air or print space so people have to hunt for real "News" and "Journalism". The majority don't have the time to do so, mostly because the attack on our way of life and government has been very thorough. Do you think that wage reductions requiring both parents to work, the massive increase in single parent homes, and the overall wealth reductions for the majority of US Citizens is purely accidental? I say think again! Gary Allen was telling gave us a play by play of the take over about 40 years ago in a book called "None Dare Call it Conspiracy" which the majority of people living today have never heard of.

The authors clarify that the data available are probably under-representing the actual extent of control of the U.S. by the super-rich:

Well I sure am glad that I'm no longer a "conspiracy theorist" for making the same claim for the last 30 years, at least according to one University. Now we need to go about fixing the issue and restore the Republic!

It's happening. First, take a look at a map of the Tenderloin, from "Areas to Avoid, San Francisco." Twitter HQ is in that area, between 9th and 10th on Market, and the long-standing "mid-Market area" around there is rapidly being rebuilt. In fact, just about everything south of McAlliister has been gentrified, except for parts of 6th St and a small section around 7th and the north side of Market. Rebuilding is underway along the Van Ness corridor too, and has more or less chopped a block off the Tenderloin on the west side. That's the old "Polk Gulch" area, once a gay rent-boy hangout.

So the SF Tenderloin is about half the size it was a few years ago. Progress continues.

If those San Francisco residents who are "entrenched" had to pay for their taxes like new residents do, they would be paying 1.25% per year property taxes on the current value rather than the basis of when they bought the property.

That's a great reason to do what rental property owners do, and own a company that owns the property, instead of owning it themselves. Then if they ever want to sell it, they can sell if for a heck of a lot more money by selling the company, rather than selling the property, so the taxes don't go up any more than if you'd bought under prop 13 and never sold.

That's the McDonald's model (McDonald's happily admits to being a real estate company that happens to sell burgers and rents out properties their franchisees). It's also the same model that the Kaiser Family Trust uses.

Going the speed of light is bad for your age.
