    Galileo was politics, not about scientific theory (the church actually agreed with his science).

    Bruno, expanded up Copernicus, but what got him in trouble was proclaiming life on other worlds and that man is not unique. Now, while it is quite possible that there is life on other planets, even quite probable, there is yet no scientific proof of it. And, Bruno, was turned in by his peers, not the church going after him -- of course, once the church got a hold of him, things went very poorly for him (like burning at the stake as a heretic).

    While he may (or may not) have been wrong, that isnt the relevant part of it. The burning at the stake because he was a heretic part is the relevant part.

    Finally, DaVinci was a life long Catholic and even in his will, made arrangements for masses to be said on his behalf.

    Which is irrelevant to whether or not he was persecuted - which he was, and escaped worse due to the patronage of another country. Many people who are lifelong catholics have found themselves kicked out of their churches for a variety of reasons - yet remained catholic. Even in this day and age... 40-50 years ago and earlier for wanting to marry interracially. Today, for being anything but straight. And a plethora of other reasons over the years, where a variety of people remained catholic even when they were being ostracized, excommunicated, abandoned - or (as in the people we discussed above) burned at the stake. I always wondered how many catholic "witches" were burned at the stake and died horribly still considering themselves christian?

Supposedly the new, more expensive fuel injectors, get better fuel economy... so why is it that cars get WORSE fuel economy now? Surely it's not the few pounds of extra weight that airbags and ECUs add to the equation. Almost every car on that list gets better CITY mpg than today's non-hybrid cars WITH fuel injection systems and an ECU get for HIGHWAY driving. Why is that again?

    So... nowadays, with safer cars that weigh about the same, and have comparable engines (displacement) and fuel injectors, why do they get such horrendous gas mileage? Performance (acceleration) on a low end to mid range car is near the same - or not too far off to make it undriveable... the VW Dasher did 12 seconds 0-60, or 19 with the diesel engine. Not bad for almost FIFTY mpg.

    I'd be happy with a bit better performance, and say... 35-45mpg (instead of 40-57mpg) highway... but the car companies seem to have forgotten how to do that... though again, I would expect that the better, fuel economy improving technologies (fuel injectors and ECU and such) should have helped with that all on their own.

A simply example is the entirely free "Tricorder" app in the Android Marketplace (yeah, I'm a geek... what can I say?). It offers fake data (or no data) for sensors that dont exist on certain phones, and offers real data for sensors that do exist. Works with everything from the G1 up to the Droid. Having simple device profiles also allows for fine tuning the data collection to the specific sensors and phone. Also a pretty trivial step if one has access to the phone, or feedback from the community (which is pretty easy the way the Android Marketplace is set up for any paid app). Other apps, like the free FoxyRing allow calibrating how it reacts to certain data.

    And if it's a paid app (especially as free apps have figured out all of the above), it behooves the developer to take those few extra steps. Since many of the apps get downloaded to the SD card, and then run an installer, it should be pretty simple to (a) install multitouch interface support or (b) install standard touch interface; while also determining which sensors it can use, etc and storing that data so it knows which to use and which dont exist on each run.

There are times I've had to drive in NYC and been on a two way main street going against the flow of traffic lights, meaning I've gotten stuck at a bunch of traffic lights during my trip. As anyone who has had engine (or lack of fuel) problems has noticed, if one repeatedly tries to start their engine, the battery will eventually get below "restart power levels" - meaning a bunch of people stuck at a traffic light without enough power to restart their engine. Add a cold winter day into the mix and this definitely should apply. As it is, I have experienced "uber cold" days on my visits to upstate New York where it sounded like if I had two or three attempts to start my engine, I would be lucky. Fortunately, my car only requires one. But driving a few hundred feet, shutting it off and trying again, then repeating that 5-10 times in under a mile would probably run me into problems as the car wouldnt have been running long enough at high enough RPM (1800?) to (a) recharge the battery enough for another start at those temperatures and/or (b) heat the battery enough for it to be able to deliver more starts.

    You are forgetting that it is much easier to start a warm engine, a cold engine does not engage for several cycles but a warm one often engages on the first piston stroke in any given cylinder. Actual battery drain would be much less than you'd expect, which would also reduce the amount of heat generated in the starter windings.. A car that has been running few minutes before hitting a stream of lights would do fine. Likewise, how many drivers in "uber cold" places do not idle their car a little while cleaning off snow and/or getting the interior heater blasting?

Wake up in NYC on a very cold winter morning (there were enough this year), step into your car, drive the half block to the first traffic light without having warmed up your car like most people do when in a rush for work, and since the light is red, your car now turns off, engine still cold.

    So it seems like they're at least aware of the intricacies involved in maximizing fuel efficiency. Their idea seems to be that, if the signal is on a timer, they can use that information (which is unavailable to the driver) to maximize efficiency.

    It is also unavailable to them in many cases, as there are still a bunch of mechanical, and electro-mechanical (but not computerized) timers that do not provide that data.

    Then there's a matter of (the car) being able to determine what data to pay attention to. Is that signal from the traffic light I am approaching? The one I just passed? The one a block ahead?

    Or of course, if it's just based on the assumption that the signal is on a timer and "gee, it's red" then there isnt a way to know how long it's been red. Is it a 2 minute wait, or is it about to change back to green?

    Then there's the complexity added to the situation where many many traffic lights have road sensors now, which affect the timer cycle. Sadly, the better intersections to use such a technology are in the suburban areas and some few city areas. And many of those traffic lights fall into this category, making the application of this technology useless.

    Now (going back to an earlier point in this post) if it's a matter of using this for "smart lights" that are computer controlled and can broadcast their status and timing, there's the added safety factor that I havent seen discussed; namely, if your car can read that data... so can you. How long before someone figures out what that data is, makes a mod and starts selling it? How many people will be looking at their "traffic light monitor thingy" watching the countdown to green and figure they'll "jump the green" - or watching the countdown to yellow and accelerate to make the light?

    Without such technology, such situations already cause all sorts of accidents from people trying to gauge such things. Heck, I've watched someone wait for the cross traffic to get a red signal, and floor it into the intersection. Sadly for them (and more sadly for the other vehicle occupants), they forgot to take into account two things: (1) the cross-traffic turning light (that goes on after forward traffic is stopped), and (2) the fact that various lights have different delays between the red and cross-traffic green - which is something many drivers riding the yellow try to exploit. Fortunately, as the driver turning wasnt going fast, and the driver who jumped the light didnt have enough distance to gain any real speed, the accident was minor.

For those of you who have an actual temperature gauge in your car, you know that is not true... so I am not sure how accurate the rest of the government's data/speculation is (or quite simply, they did not test enough cars).

    That aside, there are other problems I have not seen mentioned, for instance dead batteries. If you are a city driver, and barely get over engine idle rpm during your drive, constantly stopping and restarting your engine can drain your battery. There are times I've had to drive in NYC and been on a two way main street going against the flow of traffic lights, meaning I've gotten stuck at a bunch of traffic lights during my trip. As anyone who has had engine (or lack of fuel) problems has noticed, if one repeatedly tries to start their engine, the battery will eventually get below "restart power levels" - meaning a bunch of people stuck at a traffic light without enough power to restart their engine. Add a cold winter day into the mix and this definitely should apply. As it is, I have experienced "uber cold" days on my visits to upstate New York where it sounded like if I had two or three attempts to start my engine, I would be lucky. Fortunately, my car only requires one. But driving a few hundred feet, shutting it off and trying again, then repeating that 5-10 times in under a mile would probably run me into problems as the car wouldnt have been running long enough at high enough RPM (1800?) to (a) recharge the battery enough for another start at those temperatures and/or (b) heat the battery enough for it to be able to deliver more starts.

    Also, unless starter technology has changed recently, the starter has a cool-down period between start attempts. Something mentioned in only a few car manuals simply because one starts the car, drives it, then shuts it off - usually exceeding the cooldown period. If you are needing to stop at a traffic light every city block, and restart your engine, then chances are, you aren't reaching the end of the cooldown cycle. The more the starter is turned on without reaching it, the hotter it gets. Anyone who has played with an electric motor knows what happens if they overheat.

    And as for the engine wear part of the equation, as anyone who knows a little physics can tell you, starting an engine does wear it more than normal driving... something to do with overcoming inertia (ie: the massive flywheel, and the internal inertia of the engine itself). Yes, above-normal driving (and to a much lesser extent, normal driving) still has similar factors to overcome, but there are other differences involved, namely that the flywheel is before the torque converter or clutch and the torque converter/clutch "absorbs" some of the "stand-still" force being overcome in driving/accelerating (ie: not as jarring to the engine - in comparison to "wrenching" a standing still flywheel into motion).

    And of course, all of the above could entirely be speculation... but that's not really the point that matters... the point that matters is, it's all based off one or more combinations of vehicle manufacturer information, various studies on the matter, and various real world applications of the situation (cold s
