  1. Re:Lots of us ready and waiting... on Progress On Electric Cars · · Score: 1

    Those are good points.

    I should have said "much of the complexity of a gas engine", not "all". My bad :)

    What is amazing is just how simple a well-designed all-electric vehicle can be compared to a gas vehicle. No radiator. No brakes (regenerative instead). No sparkplugs or ignition. No injection system and pumps. Usually no transmission (which can be as complex as a gas engine, itself). No oil or filters. No alternator. No intake system nor air filter not valves. Possibly no hydraulic systems. No starter. No gas tank & evap canister. No exhaust system nor muffler. No catalytic converter.

    Those components are all replaced by a larger battery system, a charger, and a few sealed motors.

    I have often thought of that. I am guessing that most home owners that don't have a garage but do have a driveway can just use an extension cord and plug on the house. For those with no driveway, they might opt to just bury a power cord and have a controlled outlet near the street. It really isn't that complex and probably not very expensive (although going under a sidewalk could be an issue). Put a power switch in or near the house to prevent someone from stealing your power and you are ready to go. Might need some type of sensing gadget to protect children from messing with the outlet or shorts.

    Of course, for people who don't have their own street frontage, it does become a problem. I suppose a city could address that with city-supplied and metered power outlets. It would be expensive, but streets usually have power already running down at least one side.

    Step/assumption 1- scrap the SUV and get an electric car (doesn't have to be tiny, just reasonable). Step/assumption 2- a rage of 100+ miles per charge. Step/assumption 3- you need to buy a replacement vehicle because it is time to replace the old one, not just to make the switch. Step/assumption 4- electric cars have a large battery replacement expense after several years, but it might be about the same costs as gas engine car maintenance over the long term (gas engines are FAR more complex)

    With those assumptions, if you were driving even 30 miles to work and back every day and for errands and trips on the weekend and your current SUV gets a respectable 15MPG, that is 2 gal of gas a day. If gas were around $3/gal (which is not unreasonable, and it will get MUCH more expensive over the years), that is $2,190 in gas costs per year. With electricity, that cost would be about $250/year; a savings of $1,940 per year, or $9,700 per 5 years. If gas jumps to $6/gal (again, not completely unrealistic in several years), that 5 year savings could be $19,400.

    So.... it kinda depends on how much you drive and how much more an electric vehicle costs vs. a non-electric vehicle to purchase. For many people, the savings would be great, for others (like me, who drives very little) it would cost *MORE* to own/operate an electric car. And, still, for others, it will be a break-even.

    But in the long run, it is the right thing to do. Electric cars are more reliable, quieter, simpler, potentially higher performance, easier to maintain, and pollute far, far less. Let's hope consumers have some real options soon.

    It doesn't matter *WHAT* was used to generate the electricity, it will *still* be cheaper and cleaner than burning gas in cars. Large power plants are tremendously more efficient and clean because they have the scale... even burning coal (as long as they are modern plants). Don't focus just on coal & oil. Throw in natural gas, solar, geothermal, nuclear, hydro, and wind... they already account for a huge percent of electricity production and increasing each year.

    And using electricity means that everyone has a fuel source right at home, ready to go. No new infrastructure. No hazardous or explosive alternative fuels (like hydrogen or LP gas). No special equipment or training. Plug it in... Done.

    The Tesla and Aero are interesting, but waaaaaaaaay out of normal price range. And most of the other electric cars don't cut it. This is what I want, and probably what most consumers want:

    1) A real sized car, not a tiny econobox with motorcycle-sized tires
    2) Range of at least 100+ miles per charge (I am guessing 80% of people are within a 20 mile round trip to work, 90% within 30 miles, and 95% within 40 miles; so other than occasional, long road trips, that is a lot of coverage).
    3) Ability to charge with regular home voltage/current (don't care if it takes several hours to charge overnight)
    4) Real performance- at least as fast (accel & top speed) as a gas car (like a 3 liter V6, not a 2 liter 4cyl)
    5) Features- full A/C, heat, heated seats, auto climate control, GPS, cruise, auto lights, auto windows, defroster, etc
    6) Safety- comparable to a quality conventional car- crumple zones, airbags, seatbelt tensioners
    7) Reasonable price- comparable to a quality conventional car, although many of us are willing to spend more for the advantage of electric... but not 50%+ more

    When that happens, I am betting people will flock to them. Hybrids (plugin or not) are just too complicated; they have all the complexity of a gas engine (cooling, emissions control, transmission, lube, injection, etc) with all the added cost of electric (motors, batteries, charging systems).

    Will hardware vendors release their objects/stencils in something non-proprietary? As you said- not likely for now. But that doesn't mean OpenOffice Draw isn't perfectly capable of creating nice diagrams. In fact, people tend to grossly underestimate what can be done in OpenOffice Draw; mostly because many of the powerful features aren't immediately obvious and/or it is positioned more as a vector drawing program and not a diagramming program.

    Absolutely. Quantum computing aside, the idea of wireless communications via entanglement is absolutely fascinating. It could lead to instant communication with anyone, just about anywhere in the universe! No towers, no RFI, and absolutely secure from point to point. The major downside is that you probably have to have a centralized "entanglement switchboards" to actually relay the communications from one person to another, since you can't entangle every device to every other possible device. So that would be the weak point for security and reliability (and big brother spying).

    Anyway, I can imagine a day when my portable computer/communications device, whatever form that takes, can talk to just about anything, without ever having to think about where I am, and possibly with unimaginable runtime and unimaginable bandwidth.

    We have SCA RAID arrays. I had lots of drives. And they got used up over the years. Hard drive models change constantly, it wasn't long before we couldn't buy 36GB 15,000 RPM Cheetah drives anymore. So when we only had a few left, we purchased two new, recent, expensive 15,000 RPM SCA drives recently to work as backups for our RAID arrays on our Linux servers. Called Seagate *FIRST* to verify compatibility, as well as with Adaptec. Then a few months later when we needed to use one to replace a failed drive, it would NOT negotiate properly, making those drives useless.

    Hours on the phone with Seagate we FINALLY get confirmation that there is a "firmware problem" with the drives we have and we should "upgrade the firmware". We go through the crap of getting a "key" and being sent the firmware only to find that their self-booting program would not run on our servers. Their suggestion? Find some other SCSI SCA machine just lying around and try it there. WE DON'T HAVE any such machines. We asked if we could mail the expensive, useless drives to them so THEY could upgrade the firmware. The response was "you can send in the drives for exchange, but we can't guarantee the drives sent back will have the firmware you need". This is support?????

    I then had to go on a quest to buy identical *used* spares off Ebay/etc while we are still trying to get the newer models fixed by Seagate; thank goodness I found some, because the last old one failed just as I got the used ones in.

If the Fed wanted to "help", then they should provide funds to one or more of the newer, open-source EMR projects like PatientOS http://www.patientos.org/ which runs on a *variety* of front end and back end systems/OS's and can be implemented with 100% open source tools, all the way to the desktop/client.
