i bought a Nalgene bottle, umm 15 years ago or so now, Still using it, but i did have to buy it one new cap in that time. In the same time i've gone though 2 cars, 6 cell phones, 3 ipods, and 3 laptops. I think the ~$15 has been well worth it.
Reference library? I made a whole suite of things for my engineering classes. Like the power law for electronic, type in any 2 of the 4, and it spits the other 2 out complete with equations for "showing my work"...
Also, some profs knew damn well what i was doing, granted i couldn't tell you any of the power laws off the top of my head anymore, but then i haven't used them in almost 3 years now.
I think the idea was more "i'm a no auth AP but do not provide internet, if you need that skip me".... not a no trespassing sign, but more of a "there is not an interesting view down this path"
most sites have a very short max length. Also i like the places that break if you use a special car, or make you use only "!@&" as your special chars. Of course i have a bunch of sites that all use the same "weak" password, ${RANDOM FORUM} and such.
I forgot to mention both seem to use a planetary system to "merge" the power sources. Toyota is rather tight lipped about how that all works exactly for them, but some people have taken them apart see how they work.
As far as I can tell the Volt is simply nothing more than a Prius with more batteries. I'm fairly sure that ford bought Toyota tech for their hybrids as well. Not to discredit the tech in the prius, but changing how the car "feels" when driven would go a long way. Electric doesn't equal slow, google "white zombie drag car".
Assuming that faster == louder for piston ICEs, then yes it could be noise. At the same time you would be able to dump a mechanical gearbox, as well as most of the throttle body, the drive belt and related (use an electric water pump), all of which would reduce maintenance and costs. So the goal isn't 100% efficiency, but a combination of that and simplicity.
As for the eff./noise thing, how about a wankel rotary engine, or even a gas turbine. I'm not sure how the noise issue would be handled. Perhaps simply putting it on spring isolators would help a lot I suspect. A more complicated muffler design could as well.
Are there any high efficiency DC -> AC converters that could be used to provide power to a VFD? what about DC->AC VFDs and the use of 3 phase induction motors? If we make the control method and plug open, then it should be simple to update it later to something better. "provide 200VDC@>100A to pin 1, and accept ground over Pin2, Pin 3 will provide a 5v on/off signal for when power is needed or not needed. This signal will have a frequency of no more than one on/off cycle every 5 minutes." I'm brain dumping now so I'll let every get on with their day.
It's not that the engine comes on, but that they added a mechanical transmission. So even when in pure electric mode you have to lug it around and lose eff. though it (remember friction, and heat losses and such from thermodynamics)
Or simply skip charging the batteries in the 70MPH situation and have a light come on that would mean "not enough spare power to charge the batteries currently"
10-15%? I know you can get electric motors up near 99% even in that size, and I would bet alternators are had in the >95% range. There should be negligible transmission losses over 20 feet as well as little need to do any voltage stepping if things are designed correctly. There may be need for a fairly large size capacitor to help with voltage fluctuations. All of this serial hybrid stuff is already 20+ years old. Almost every piece of heavy machinery is a serial hybrid, including diesel trains. The only time you would be doing any sort of volatge/current change is for when charging the batteries.
Anyone know if these cars use 3 phase AC induction motors, or huge brush-less DC motors?
The volt is a hybrid just like the prius. GM was touting the car as more like a diesel train than a prius. No need for a mechanical transmission, no need for a few of the other systems that a gas car would need.
How about a low profile low rolling resistance trailer with the ICE/Generator and a cable run up to the body of the car, Heck add in a little bit of cargo room in it.
Seems like a good way to go. Lets see, 2 lines for power and ground, and 1 line for control, seems like you would only need 3 lines and a voltage signal, something like 15V for on, and 0V for off. A small motorcycle battery, and use the generator as the starter. Size the motor and the generator so they both operate at peek output/min gas consumption. Since the car already has the ability to charge it's own batteries, it should be easy to add a second mode "turn on ICE for as long as possible only when absolutely needed" Then all you need to do is size your ICE/generator so that it provides enough to power the motor and charge the batteries at the same time. A largish bank of super caps can provide power for acceleration.
I'm not sure how many cycles super caps are good for but...
The Prius is a parallel hybrid as well, the gas engine can charge the battery and move the car or simply charge the batteries.
The reason i'm upset(i use that lightly) is that 1) They have been billing and advertising the car as a serial hybrid, 2) The inclusion of all the extra drive train components is a big pile of more stuff that I'll need to maintain. I was looking forward to a car without a transmission, but this one has an extra complicated one.
hmm I thought parts of montana had un restricted areas. Also if I export the car to Europe with as part of a move the autobahn is an option. Also it's not cut and dry the over 70 is illegal even if the speed limit is 70, overtaking a car for example, or other such "emergency" maneuvers. Most people have a race track nearby that they may take the car to.
The issue for me here, is I was informed that the Volt was a serial hybrid, and not a parallel one. I know I was considering the Volt over the Prius for the simplified drive train, and mechanical systems; as well as the increased efficiency that a serial hybrid should provide.
last i knew multicast did not work for sending video with multiple starting times, like say youtube. Also using multicast for a video with 20 viewers in 20 different locations of the globe won't do anything to solve bandwidth issues in the trunks. To help out the trunks we need to start providing massive caching just before the last mile, and make it easy for providers to drop off a rack there. That way google can drop off a "youtube rack" near you and save trunk bandwidth.
The issue which is pointed out above is that multiple users exist at the same time. Even in my home in a few years there could be up to 4 netflix HD streams, 2-4 World of warcraft 6.0.1 patches(623GB each) regular browsing, Facebook 2.0(with a full size picture option for those 35megapixel images), we'll ignore iTunes, any other games/content. I could see my house consuming a "massive" amount of bandwidth during peek times, after dinner for example. Now bump up HD video to 2k4k, and basicly make those 4 HD netflix streams into 16 (2k4k video is 4x as many pixels).
I'd simply tell the shop after looking at it for a while that it looks like road debris to me and ask if they could dispose of it for me. or simply dumpster it at a local walmart.
http://www.deleet.de/projekte/daap/daapd/ any NAS box that is open enough to let you run linux on it. I'm not sure DAAPD works well anymore, or for videos, i have no idea if it does videos or anything, i hvan't needed to talk to an apple only client in years now.
Slashdot Mirror
ondemand content works from my TV without any cable box? thats news to me...
PPV, and other on demand content. From the looks of the FCC thing there is no provision to require the ability to be able to communicate 2 ways.

I sort of did for a whole class. Granted laptops were already allowed, so i just used orpie. Shame it seems to have a dead upstream though.
doesn't openWRT ship with no wireless by default?

so you scripted your printjobs to be 19 pages each then.... right right?

sure, but 75> 70 anyways.

51% depends as well, simply have 51% may not get you what ever you want. Some companies have internal rules that say a 75% vote is needed.
