    Almost all SD TV's make horrible monitors.

    They aren't nearly up to par with monitors, but they are usable. Of course you're limited to 704x480 or 704x576, and the interlacing will cause flickering with smaller fonts. However, if you use large fonts (eg. 24pt or 80x24 text console) it can work just fine.

    Just look at any DVRs for an example. I often browse the web on mine, when I want to look up something fairly simple. Though I certainly don't recommend reading text off a TV screen for hours at a time. If you're poor, the lower quality is probably worth the $100 savings over buying a monitor.

    The irony is that I can buy a nearly top of the line computer for $199 here in the states. It just takes some smart shopping and rebate forms.

    You can't count "Rebates", "Sales", "Clearance", etc. They only work because there is a thriving high value market in the US already. It's often a tactic to get their company name out there, or develop consumer demand to get shelf-space in stores. In other words, if there weren't millions of people willing to pay $500+ for a computer, you wouldn't companies taking a loss and dumping old ones at dirt cheap prices. So, it's good to be poor in the US, but it's not a model that can be applied elsewhere.

    However, I do share your skepticism at the price of this thing. If no monitor is needed, it would be easy to make a (current, but low-end) PC for just a bit over $100, and have a much better chance in the Chinese market.

  7. Thumb trackballs on Mouse or Trackball? · · Score: 1

    I've been using a Logitech "Trackman" for several years, and I have a couple observations.

    I must grudgingly agree that I'm not as accurate as I was with a standard mouse, but the inaccuracy really only consists of a pixel off when trying to draw a straight line, so nothing major. And perhaps that wouldn't be a problem if I bought a slightly more expensive model with more fluid motion. Though, I imagine if I needed to be, I could lift my hand up, and use my whole hand to carefully control the cursor for detail work. I could also reduce the speed at which the cursor moves, and get the same effect.

    However, the big reason I suggest a thumb operated trackball to everyone all the time is because it's FAST, damn fast. With a 1" movement of my thumb, the cursor goes from one side of the screen to the other. In a tenth of of a second I can (100% accurately) click on any element, anywhere on the screen, without the slightest bit of effort.

    More importantly, it is much less stressful. With a mouse, or a traditional trackball, you're using your hand, wrist, and shoulder a tremendous amount, which all starts to get sore after a few hours. Moving your thumb around completely eliminates all of that, and changes it to just moving one finger, an inch at a time. It's a huge relief.

    I can recall my thumb getting sore on rare occasions, but I can remember much more often my wrists, hand, shoulder, neck, etc. hurting from using a mouse (for a fraction as long) every day. It's just an added bonus that I get things accomplished far faster.

    I've been tempted by GEM in the past.

    I've got one (don't ask, it's complicated). I don't recomend it to anyone.

    1) The center of gravity is very low, and you sit extremely high up, on bench seats that are straight up (not leaning back, which would help a little bit). It's hard to describe just how terrible the ride is even at the top speed of 25MPH. Hitting a pothole could very easily throw you from the vehicle if you aren't wearing the seatbelt. God help you if you modify it.

    2) The shocks are rock hard. You'll feel every single bump. Of course, if they were soft the problem of throwing people out would be more serious, as well as the potential for flipping it (onto its' side) while turning.

    3) The accelerator is absolutely horrible. You have no choice but to rest your entire foot on it. That may not sound bad, because no cars ever made have done anything so stupid, so it's unfamiliar to everyone (Even golf carts are made the right way!). What it means is, on anything other than a perfectly smooth road, you have no control over speed. The slightest little bump will push your foot up or down uncontrollably, and you will constantly accelerate/decelerate with no control at all. Basically, you can be stopped, or you can be at full speed, nothing in-between.

    If they can get that sucker down in price for a 4-seater with hard-doors and a better top speed (say, around $6k), I'd jump on it in a second.

    All of those are no problem, actually.

    There is a 4-seater available. Hard doors are available as an option. You can get them new for something like half the advertised price (who knows why, perhaps they have a quota), and used much, much more cheaply.

    As for speed, the electric motor has far more power than needed. It's only limited to 25MPH by the computer. In fact, when accelerating, it's standard to spin the wheels without even trying. If you were to replace the front pair of wheels (tiny, 5" IIRC) with some that are 2X the perimeter (approx. 7 or 8" wheels), you could easily get it to go 50MPH. Though, I don't know how much that would affect the range. And that's not at all street legal of course, and look through my list (above) to understand just how terrifyingly dangerous that would be with a GEM.

    There's nothing to prevent hybrid systems where the ICE component is a diesel.

    Yes, in fact there is.

    Hybrids do so well with gasoline engines, because they can workaround the inefficiencies of gas ICEs. With diesels, there's very little benefits to be had.

    With gasoline engines, shutting it off for 30 seconds and starting it again is a benefit. Diesels, however, are much more fuel thrift, and can idle down to almost nothing, a few drops of fuel, so you gain almost nothing. Diesel engines are also much harder to start up again than gasoline engines, so the small benefit you got from shutting it off is going to be spent in energy starting it again.

    With gasoline engines, it's extremely inefficient to accelerate from a stop, diesel engines are much better.

    With diesels engines, you could still get some benefits from regenerative braking, but it's difficult to see where you'd spend that energy again, since shutting off the engine for a few moments is not likely to ever be economic. Perhaps diesels would be a good candidate for regenerative braking using hydraulic storage.

    Removing one or two cylinders and using the electric motor to make up the power different, as is common in hybrids, isn't likely to help either, since diesels can adjust their displacement as much as necessary, so having more cyl. isn't much of a fuel economy hit.

    So, by all means, I'd like to hear someone explain what diesels are going to gain from being hybridized, because I can only see tiny improvements, and great expense to get them.

    Internal combustion engines are extremely low efficiency. If you were to directly take a tank of gasoline from one car and ship it to a power plant, you could power at least 4 electric vehicles off of it, and quite possibly more.

    Pollution controls are far better.

    And the grid is served not JUST by coal, but also by wind, solar, hydro, etc. In CA, almost 1/3rd of the electricity is generated by hydro, and the majority of the rest is generated by natural gas (still fossil fuel, but much cleaner) and nuclear plants.

    As for coal plants, we have a legislative problem... Old and polluting coal plants are grandfathered in. If forced to build new ones, at least they will be far cleaner than the old.

    Sterling engines will run on just about any fuel, but so will ICEs... Throw some Tequila in your gas tank, and watch it run. If you can figure a way to shovel ultra-fine coal dust in there, it'll burn that too. Diesels also support a wide range of fuels, and run at surprisingly good efficiency with most. And turbines can handle any fuels a sterling engine can.

    The problem lies in adjusting the engines for the different fuels. You aren't going to fill up with fossil fuels one day, and pure ethanol the next. Adjustments need to be made, at least if you want any kind of reasonable efficiency.
