Comment Won't everyone be a millionaire? (Score 1) 467

At least, won't everyone who's paid a middle to upper middle class wage, buys a house and saves for retirement eventually be a millionaire?

If you want to retire at 65 and have enough money to live a decent life for 30 years after that, you need pretty close to a million dollars plus a paid-off house. And, frankly, it's not that hard to accumulate a million dollars of net worth over a ~40-year career, assuming reasonable returns on your retirement account and modest appreciation on your home. I'm actually targeting net assets of two million for retirement, given that it's still 20 years away and I expect that inflation will roughly halve the value of the dollar between now and then.

My (admittedly pretty hazy at this point) memory of heat engines is that their theoretical peak efficiency depends on the thermal delta they manage to achieve. Exactly the same resource that thermoelectric materials scavenge (albeit at miserable efficiency) into electricity.

Anybody who actually has some grasp of the matter want to chime in on where and why you would use thermoelectrics (and how efficient they would have to be) rather than simple insulation or one of the various waste-heat-recovery systems that transfer some amount of the heat remaing in outgoing exhaust gases into incoming working fluids?

Is the thermoelectric advantage purely that, assuming material reliability is OK, they are a 100% solid state, trivial to scale from 'handle with tweezers and magnification' to 'pretty large', and their output is easy to transfer and useful for all kinds of things after just a little DC-DC cleanup, or are there actually situations where they might be absolutely more efficient than insulation and heat recovery, rather than just easier to tack in almost anywhere in a design that you have a few extra cubic centimeters and expect a temperature difference?

Regardless of the number of exclamation points you use, Mountain View and SF housing do affect one another. I know several people who have lived in both areas and who have opted for one over the other based on questions of price and convenience. Said (insane, IMO) prefer to live in SF, but some choose MTV because SF is too expensive. Lowering the cost of housing in MTV further -- and making it more convenient to the Google campus -- would induce some more to leave SF.

It's not a "re-examination". It's a butchering.

You say that like it's necessarily a bad thing.

We've got to stop acting as if the Founding Fathers were like Moses descending from Mount Sinai with the Constitution chiseled on a couple of stone tablets. They were brilliant, enlightened men for their day, but the Constitution is not a document of divine inerrancy.

The US Constitution is the COBOL of constitutions. Yes, it was a tremendous intellectual innovation for its time. Yes, it is still being used successfully today. But nobody *today* would write a constitution that way, *even if their intent was exactly the same* as the founders.

For one thing it's full of confusingly pointless ("To promote the Progress of Science") and hoplessly vague ("securing for *limited times*") phraseology that leaves courts wondering exactly what the framers meant, or whether they were just pointlessly editorializing ("A well regulated Militia, being necessary to the security of a free State").

It's also helplessly out of date. The Constitution was drafted before the existence of mass media and advertising; before photography even. It was the appearance of photography in newspapers that woke people up to the idea that they might have privacy rights that were being threatened. A Constitution written in 1900 would almost certainly have clauses explicitly recognizing a right to individual privacy and empowering the government to protect that right. A Constitution written in 2000 would almost certainly have clauses restricting the government from violating individual privacy.

And then there is slavery, an outright *evil* which is enshrined in the founder's version of the Constitution. That alone should disqualify any claim they may have had to superhuman morality.

So if we take it as given that the US Constitution is not divinely ordained, it's not necessarily a bad thing that the current generation should choose to butcher what the founders established. Would you re-institute slavery? Allow *states* to deprive citizens of liberty and property without due process? Eliminate direct election of senators?

So it's perfectly reasonable to butcher anything in the Constitution when you're proposing an *amendment* to the Constitution. That's the whole point. We should think for ourselves. In doing so, we're actually carrying on the work the framers themselves were doing. Every generation should learn from its predecessors, but think for itself.

You've never worked for a start up? It's all about the IPO. Technological advancement for the past 15 years or so anyway has been driven by the hopes of IPO, or as "plan B", acquisition by a big company at a price established by what an IPO might bring.

The secondary market sets the benchmark for what a successful small company is worth, which in turn drives the availability of investment in start-ups and other small businesses.

Except that's bullshit, because if people really cared about using their guns to defend our freedoms, there would already be a gallows set up on Capitol Hill with half of congress swinging from it.

Utter nonsense.

There are problems -- lots of them -- but peaceful civilian control of our government has not yet failed. Things aren't bad enough to justify civil war, but that doesn't mean it will never get to that point.

And to pretend that the Founders never intended the Constitution to be amended is silly since we have an amendment process.

Of course they intended it to be amended. Which means that if people would like to ban civilian firearm possession, they should amend the constitution. Not that any such amendment would have a prayer of getting ratified.

Well, if you want reasonable housing prices in the face of climbing demand, then it's your problem. Without new housing in quantity in Mountain View, existing housing in Mountain View will cost more, and the same effect will ripple out to surrounding communities, including SF. The increased number of commuters will also increase traffic on the roads (though not as much as it could, thanks to the Google buses).

If you don't care about housing costs and traffic in the region, then it's not your problem. I don't live in the area, so it's certainly not my problem.

Comment Re:Effectiveness of a space elevator. (Score 1) 98

Very good point. I stand corrected.

Putting something into LEO with an elevator would probably require lifting it well beyond LEO to get something close to the right orbital velocity, then applying thrust to fix up the resulting eccentric orbit. It'd still be cheaper than lifting it from the ground into LEO... though it occurs to me that the reason it would be cheaper is that it would get its orbital velocity by taking energy from the elevator. That could be restored by lowering a mass from geostationary orbit.

I hadn't consider it before but it seems like a space elevator would need station-keeping thrusters to maintain its orbital velocity since it would be sapped a bit by every kilogram lifted from the ground. Without thrusters you'd need so send a like amount of mass down, which means for every kilogram you lift up and want to keep in orbit you'd need to find a similar mass to send down. Maybe ore from asteroid mining operations? Of course, then the source of the orbital velocity you're using to restore the elevator's velocity is the thrusters that put the ore into the right orbit to go down the elevator.
