Mod the parent (parent poster, that is) up. dculp is correct. I'd add that dculp seems to be pretty special though too. Teaching is very tough. Discipline and behaviour problems are numerous and hard to deal with -- especially for tech folks who may not be as skilled at dealing with kids. Extra hard when there's no (or negative) parental support. Even harder if your principal doesn't support you. Anyway, as said, the major part of the solution is to figure out how to get parents involved. *That's* the first domino. Convincing parents that it's vitally important to be involved with their kid's education is a tough cycle to break though.

    > They aren't being "pumped cash". That's why teachers are underpaid, and we don't have enough of them, [snip]

    Teachers are indeed being underpaid, but we actually *do* seem to have enough of them. The jobs are being filled, mostly by folks who were laid off and got certified to teach. Also, going into teaching is a pretty straight path, and many college students looking for a career like straight paths (i.e., take classes, take cert exams, do your student teaching, get a job).

    The problem with American schools is that the majority of American parents don't take education or discipline seriously. Teaching is an *awful* job. Almost every kid wants to "take it easy" and be on a perpetual break where, instead of studying, their goal is to see how much they can annoy the teacher. It's incredibly frustrating -- teachers have all the responsibility, but very little authority. When they send the kid to the principal's office, they get their boss (the principal) asking them why they're unable to handle their kids. When they call the parents, often they get hassled by the parent and asked why they are "picking on my kid".

    Actually, calling the parent is usually an exercise in frustration because the kid gets home first and often deletes the message from the answering machine before the parent gets it.

    And then there's the frustration of seeing the few good kids flounder around not getting the environment or attention you know they need.

    And I'm only talking about regular suburban schools. This doesn't even scratch the surface of how bad it is in inner city schools, where the teens act like the school is their own personal gang territory.

    What exacerbates the problem is that anyone who has any awareness at all about this, and who can afford it, gets their kid(s) out of public school ASAP. Now you've got even fewer of the good and/or smart ones left to make a positive influence on the rest.

    In the final analysis, since the goal is to have an educated citizenry, I think the best thing for the country is to fix the public schools. Get tough on and serious about the kids and parents who are ruining it for the rest of us. I don't know how to fix the real trouble-makers though. These are kids who've probably had it the worst growing up (abusive drug-addicted parents, poor nutrition, gang involvement, etc.), and we don't want to abandon them, but we also don't want to allow them to wreck it for everyone else.

    I think the reason it would be difficult is simple: battery lifetime is dependent on how deep you discharge them. You'd have folks pulling into the swap-station who've discharged the pack all the way down to the bottom, thus wrecking it for everyone else.

    Battery packs take a lot of maintenance if you want them to last.

    Well, dbIII has a point though. Through each step of the way, you lose energy. Even if you get it via solar cells, you need to run that through the charging circuitry (so there's some loss), then charging the battery is not 100% efficient, so you lose some there (this isn't even considering when your cells get out of sync and you need to overcharge the pack to get them all to the same state of charge -- outgassing is electrolysis, and that takes lots of energy to do). Then while the batteries sit unused during the day they lose some more (self discharge). Then when you use them, the power goes through the power controller, so there's some loss. *Then* finally you deal with that last loss at the motor itself.

    Now, I could probably live with all that (note, battery packs require significant maintenance to last a reasonable amount of time), and I could probably even deal with the fact that if you habitually discharge your battery below 50% or so you kill your pack (so don't do it). And I might even be able to deal with the temperature sensitivity of rechargable cells (though it would require heating them in the winter where I currently live). I've posted here in favor of EV's in the past, but now I think maybe I was incorrect. dbIII points out the straw that breaks the camel's back: lugging these heavy battery packs around -- it's just wasteful to carry all that weight around wherever I go.

    Battery technology is pretty old and well-understood. You mix and match elements on the periodic table and work the thermodynamics to see if you'll get a good voltage, favorable reactivity, no bad environmental problems, etc. There's no magic anymore -- all the combinations have been tried. Maybe novel manufacturing practices and materials science can give you a few percent better performance, but there's good reasons why people still use lead-acid. And regarding these lithium batteries that can "vent with flame" -- no thank you. Also, re. NiMH, they have their own host if ideosyncratic issues.

    I used to think it was just as simple as sticking cells in a car, replacing the engine with an electric motor and off-you-go, but now I see (and I hate to say it) that it's actually much more of a prickly problem than I thought.

    My bet is now on biodiesel, I think. It's net zero CO2 producing, you can use it in furnaces, generators, cars, etc. You can make the stuff yourself in your backyard, farmers can make it,... there aren't any real minuses that I can see (except that you still are relying on small explosions under the hood to get you from P_A --> P_B, so your engine parts will still wear out much much faster than EV motor parts).

    Of course, please continue using good old recyclable lead acid cells in your shed that store extra output from the wind gennie and the solar panels on the roof. Heavy is ok if you aren't lugging them all to and from work every day. :)

  8. Re:Not as market-driven as you'd hope on Smithsonian Removes EV1 Exhibit · · Score: 5, Insightful

    GM knew they could sell electric cars.

    I think the point you're missing is this:

    Electric vehicles are simple and inexpensive to design and build.

    Way simpler than ICE (internal combustion engine) vehicles. ICE's have to have many many moving parts working in sync to even run at all. There's even fluid dynamics involved for air, fuel, and lubricant flow. It's insanely complicated compared to an electric car which happens to consist of only 4 major parts:

    • the electric motor,
    • the charge controller,
    • the power controller ("throttle"), and
    • the batteries

    That's it. Any other fancy features (like regenerative braking) are just gravy, and you don't need them for a simple functional vehicle.

    Car companies could make an electric "VW Bug" type car in their sleep. Hobbyists have been making them in their garages for decades.

    The fact of the matter is not that car companies can't make money on them, the fact is that they wouldn't be able to make nearly as much money on them as they do with ICE vehicles. Here's some reasons why:

    1. Energy efficiency. All the extras that car companies like to change extra for (power windows, power doorlocks, automatic transmissions, big stereos, heated seats, etc.) become much less viable with small economical energy efficient vehicles. Instead of "features" they become things that reduce how many miles you can go on a charge.

    2. Size. EV's tend to be fairly small. Car companies like to charge big money for big vehicles.

    3. Parts. EV's are very reliable. We're used to driving vehicles around which have explosions going on inside their engines. This wears ICE's out fast. Electric motors last an very very long time with minimal maintenance. This means car companies will not make much money selling parts. Batteries, OTOH, do wear out. But they're dimensions are currently pretty standardized, and so you wouldn't have to go to the dealership to recycle them.

    4. Lifetime. As mentioned, EV's last a very long time. Car companies like their customers to drive disposable cars, so they can be sold another car in a few years.

    5. Oil. You can't discount the relationship that car companies almost assuredly have with oil companies. It's symbiotic. Do you think maybe GM has heavy investments in several oil companies? I'm sure they certainly do. And widespread EV sales would hammer oil company profits. Do you think maybe oil companies have large investments in automobile companies? Let's listen in on a possible future phone call:

    Oil company exec: Hi. Say, all these EV's you're producing - we're really getting hit hard over here. 'Little help?

    Car company exec: Yeah, we're doing pretty good with 'em. Folks really love 'em. So, we don't plan on not selling them any time soon.

    Oil: Yeah, well, see,.. we were thinking, maybe then it would be a good idea if rearranged our corporate stock ownership portfolio a little... to realign our core ... [snip marketspeak].

    Interesting point. I think you are correct, however there are also other forces at work. The net result of what you get seems to also depend upon:

    A. Whether or not there's a strong contributor community (not just a bunch of users) formed around the given project, and

    B. What your ultimate goals are for your project (if world domination is on your agenda, you'd better make your stuff usable and has good docs -- case in point: most GNU software).

    Now, open source software (as opposed to Free as-in-libre software) has a very different dynamic. With OSS, the devs usually really really want you to use their software -- they want more users; they want their software to be popular -- and so are motivated by that goal to write pretty good docs. Companies may be able to make money on OSS by adding proprietary extensions and then charging for it, so it's in their best interest to make *their* parts easy to use, and *their* docs better (which may or may not include improving the open-source components).

    In my experience, free software projects tend to have stronger community involvement than OSS projects.
