    CVT has a long history in racing with the last notable attempt by Williams in F1 in 1993. Many automation aids were banned in 1994. Just Google for: Williams F1 CVT.

    The durability issues have been mostly related to frictional belt CVTs. Audi's multi-chain design is able to handle more power, and Toyota's reapplication of the standard differential/planetary-gear system as a CVT answers your meshed physical gearing need. Here's a description of the latest gen PSD.

    As we've all experienced, constant acceleration cannot be really felt whether it be in the elevator, standing on the surface of a rotating Earth, or in a CVT driven car. So ya, pretty weird. :)

    What speeds do you pulse-n-glide on? There's an upper limit (usually highway speeds) where pulse-n-glide isn't really useful because air drag begins to dominate the normal frictional losses besides probably running above the efficiency peak of the engine.

    Otherwise, PnG technique should work with any car at slower speeds, especially these racers of TFA.

    You forgot Tesla's electric car that ran on either broadcast power or power from the air/Earth with technology similiar to Moray's. It seems much of Tesla's paperwork was seized by the Office of Alien Property immediately after Tesla's death (even though Tesla was a US citizen), and it's unknown how much of his paperwork "disappeared" even though "much" of it was returned to his nephew.

    Also, was the VTEC-E mpg based on the Japanese or American cycle? We're going to see some car coming from Japan in a few years that'll be close to 100MPG, but that's on the Japanese cycle where their highways are closer to 30mph than our 65mph. So, that 100MPG engine would translate to something like 65MPG here in the States.

  9. ICE quirk on UBC Engineers Reach Mileage Of Over 3000 MPG · · Score: 5, Interesting

    Current vehicle engines have this strange quirk.

    The engine isn't running at its most efficient conversion of gas to energy unless it's operating within its most efficient point in its powerband - a HP plateau between certain RPM markers. Check it out on a dyno. So yes, it would be more efficient to accelerate harder from a stop with the RPMs within the powerband, coast, then rinse-n-repeat.

    It's called Pulse-n-Glide by the Prius marathoners, and also on Wikipedia.

    Constant speed isn't the most efficient way to use a internal combustion engine (ICE), although it certainly is the easiest.

  11. Re:regenerative braking: Today on Smithsonian Removes EV1 Exhibit · · Score: 5, Informative

    When was the last time you did your research, early-1990s?

    Every modern hybrid today (Prius 1997, Insight 1999) have used regenerative braking, or have tried to.

    o Highway? Toyota's HSD (Hybrid Synergy Drive) puts the engine into maximal efficient RPMs while you drive and then pumps the excess energy into the battery.
    o Slowing down? Engine drag is simulated through regenerative braking until battery is overcharged, then it goes into compression drag.
    o Engine braking especially going downhill? Aggressive regenerative braking until the battery is full.
    o Coming off the freeway? Again, very light regenerative braking before you even hit the brakes.

    It's not just plain red-tail light regenerative braking you're thinking of.

    Supercaps? That would be nice, but I think Toyota threw out that idea already. There's a few modders on the Prius using Can-view to watch the voltages going in and out of the plain NiMH system as well as total state of charge.

    Most full-hybrids today have regenerative braking: Honda(Insight, Civic & Accord Hybrid), Toyota(Prius, Camry Hybrid, Highlander Hybrid), Lexus(RX400h, GS450h), etc at a decent enough efficiency level.

    mod parent up. Makes perfect sense for more polar water to pile up as an equatorial ring. A tire tube of 'fat' for the Earth.

    Remember, the Earth is never exactly spherical due to this AND the Sun and Moon combined, or on opposite sides, pulling "up" the equatorial waters. It's called 'tides'.

    Should be able to predict that tide levels have been rising in a parallel trend, but not equal levels due to water displacing less than ice.

    The scientific process, especially in a PhD dissertation, requires you to prove a negative in order to prove the positive.

    You prove:
    o component A by itself has no effect (negative)

    Ya, I've seen that..

    I even went through a bad batch of TYs where Nero said it was all golden, and most of the files were corrupted. I even got a swap from Plextor for my old Plextor 712A because there was something wrong with the laser calibration and burns came out consistently with high error rates with Plextools and the other utility for liteon drives even though burn speeds were low 4x and 8x, and I always was using the latest firmware.

    It did get better with the drive swap, but the Plextor was inconsistent enough that I went to a recent NEC 3540 and it's been fine since.

    So first try turning down the burn speed because there's no need to be burning at max speed IMO if your IO can't handle it anyways. Then check your firmware, and how consistent your error rate is with Plextools or Nero's Disk Quality scan in CD-DVD Speed utility and in a separate drive.

    C1/PIE,C2/PIF errors should be consistently low for lower speeds, and only ramp up a little at higher speeds. If it consistently spikes over the max safe error threshold, get better media, or a different burner.
