Instead of making EV's quieter, the blind should wear a belt that senses all
objects around them in a circle and gives off a beep when it detects a
moving object. They can carry a backpack that houses their batteries or
maybe the batteries to power the device can be put in the cane they use.

I think they mean Lithium Iron Phosphate, which is the hottest battery so 
far for EVs (Thunder Sky, A123)

I noticed this in the description of the new one laptop per child product.

anyone know about this battery ?
what are it's capabilities for a car?

"In the places where the XO will be used, power is often scarce. So the

I've seen a lot of backup sensors in newer car rear bumpers.  Anybody know 
the range and field of view on something like that?  Maybe turn on a noise 
maker if something is detected in front?  Isn't Volvo or somebody 
advertising a collision warning system that might be used to turn on noise? 
We wouldn't have to listen to the noise all the time.

Dan,

1.
in all the circuits diagrams I have seen the line from the MCU PWM pin 
to the IGBT driver has a pullup resistor to the 5v rail, an inline 
resistor and a couple of caps to ground. (I am no expert so check this 
with someone who is)


2.
is there any reason your not using a single high amp IGBT with something 
like Cornell Dubilier SCD capacitors?

Looks easier to fabricate to me.

Same thing I do in my ICE car. I'll do it in the EV as well once I've
got a pack that'll let me press the not-gas without dimming them. Isn't
the whole world going over to daytime running lights for just this
reason? It's been years since you could buy a motorcycle that didn't
turn the headlight on automatically with the key...

That wouldn't work for the inductive loop type of sensors. I think this 
is actually the most common type.

But from an individual's point of view, all that matters is to find a 
solution for the particular traffic lights that are giving him a 
problem. Maybe the magnets worked for the light near his home.

>>  Hi EVerybody;

   You mean they are just LOOSE ? Without a handler? A dog, a person? Seems 
like this is more the issue than noisy vehicles?Gees! It's bad enough with 
the dummy SIGHTED people running loose out there. After all Darwin's law is 
out of political favour, nowadaze, anyhow. I saw enouigh of that in my train 
driving daze! Of course a locomotive comes with a VERY loud horn and 
,contrary to popular belief, NO steering wheel! On the other end of the 
vehicle spectrem, I have hit enough dunny pedestrians riding a silent pedal 
bike in NYC. In the bike lane knocked them down when they pop out, not 
looking, from behind trucks. Boy are they Pissed! Almost as much as I am. 
Being 6'5" and 300 lbs ,they usually go away!" Now don't get me MAD! " I 
say, usually works. That there are so FEW pedestrians killed in NYC is 
remarkable to me. Other cities this is an issue too. The Portland Max, lite 
rail trains stack 'em up, too. Best method they use is the two train 
trick;( TWO trains operating in Portland that day??!! Duh!) gets them EVery 
time. Walk around the back of a departing train, ANOTHER train coming the 
other way. Remember they are electric, almost silent. BAM! another 2 hour 
delay picking up body parts! Ruins the train drivers' day, too. Nobody 
thinks of that. Maybe Tri-Met should look into those "Scoop" afairs that 
they had 100 years ago on the trolleys, that basketlike thing fitted to the 
front of the cars. A light sorta "fence"thing hung out front. A body would 
push that back, tripping a bedframe like scoop that would sweep you up 
BEFORE you went under the wheels! Simple 19th century technology! I have 
scene many versions of this on our Museum Trolleys

   Gotta agree with David R. NUTS! I like it ,well said! Modern life is 
noisy enough! We NEED more noise? Hell no! One of the most annoying noises, 
on the planet is those godamn backup beepers on trux and busses!A lite tap 
on the horn should do it. Remember YOU are driving the two tons of Led Sled 
electric? If you are going slow you will gently nudge them back to reaity? 
If your RADIO is on fairly loud? Maybe they will hear Your classical tunes? 
" Ride of the Valkries" William Tell Overture<g>!"Or, for you cat fans an 
amplified "MEOW" Like the ones ya get when you step on the cat's foot<g>!

Sure; that will work. In fact, there are of course dozens of circuits 
that can do the job.

I was trying to point out that you don't pick the circuit first, and 
then warp the application so you can use it. (We're building a toaster. 
OK, let's pick the microcomputer and operating system...) Most of the 
"design idea" circuits found in electronics magazines like this one are 
written by the marketing department of an IC manufacturer to sell their 
chips.

The right way to do it is to figure out what performance you need FIRST, 
and THEN find the best circuit to to it.

I tell the kids in my BEST class, "The first solution is the worst 
solution." It's the one you arrived at without thinking; by doing 
whatever seems easy or expedient or fashionable at the moment. But take 
some time to *think* about the problem. How *many* ways can you find to 
solve it? Often, your second or third or fourth ideas turn out to be 
better choices!

If you think about a problem long enough, you will frequently arrive at 
a "best" solution; one that is so obviously right that once you've found 
it, you'll slap yourself on the forehead and say, "Of course! That's it!"

Good idea - all of that may be a bit much, but a pull-up is definitely
necessary, and some filtering is probably a good idea.

It also costs a lot more. A 400A IGBT can easily cost hundreds of
dollars, or you can use a bunch of small IGBTs for much cheaper.

Ferro-phosphate *is* iron phosphate. To be more precise, it's ferric
phosphate. Ferrum is the Latin word for iron; ferric is Fe3+.
Phosphate is PO4 and has a charge of -3, so Fe3+ bonds to it to make
FePO4, ferric phosphate. Since ferric can change to ferrous if it had
a different charge, if the person didn't know the chemistry involved
or the charge on the atoms, they could just say ferro phosphate.

The number of poles/windings is just a tradeoff between speed and
torque; it seems like you're both saying that. For the same size, you
get the same power, whether with low torque at high RPMs or high
torque at low RPMs.

I have a similar theory, but mine consists of thinking things through until I 
have come up with what I term an elegant solution.  Not only does it get the 
job done, but it's clean and simple.  Sometimes for expediency sake I do go 
with the first solution, but I am never more satisfied and proud than when I 
put in enough thought time up front to come up with the elegant solution.  
Sometimes it takes days or weeks of chewing on a problem until it finally comes.

I may be missing something, but all I see are ship propulsion systems
that use solar or generators to charge the batteries, or move via sale
and collect power regeneratively for low-wind conditions. There's
still outside power being contributed to the system in some way,
either wind, solar, or fossil fuels.

Back to our original topic, I wrote an email to the inventor's company
(couldn't find a personal email, but it sounds like a small enough
operation that he should see the letter) requesting some more info,
and inviting him to join the discussion here on EVDL.

I asked a few questions that came to me while I was writing, but I'm
fairly new here so maybe I missed something obvious. If anyone else
wants to try their luck, I wrote to [EMAIL PROTECTED]

Tried my best to honestly express our skepticism without being rude -
hope I get a response.

---------------------
Hello,

The members of the Electric Vehicle Distribution List (EVDL --
http://www.evdl.org ) have had some pretty lively discussions this
past week trying to make some sense just what you've accomplished with
your new electric drive system. Obviously we are some of the last
people who would naysay about an electric drive solution, but there
obviously has been a little doubt about the claims -- you are stating
a rather incredible range from a rather small collection of common
lead acid batteries.

We were wondering if you would be willing to answer a few questions
and give some general information about your system (as you know, the
media often gets the facts wrong). I understand that you have some
patents on the associated technologies, and probably hope to
capitalize on this -- we really just want some general descriptions of
how the system operates, not the proprietary details.

Few thoughts off the top of my head:

1. Under what conditions did you achieve the 150 mile range? Speed,
terrain, depth of discharge at the end of the trip, etc.

2. What details can you share on your battery pack? Battery type,
voltage, capacity, etc

3. It sounds like the constant velocity transmission is key to your
claims -- How does this help you realize a longer range than you would
accomplish driving the EV through a standard transmission or directly
coupled to the drive shaft?

I'd appreciate any additional information you can provide. I'll pass
anything along to the EVDL, but it would also be wonderful if you'd be
willing to join our list for some open discussion about your EV.

We also have a site for the registration of electric vehicles, to
share information with peers and people interested in EVs - feel free
to register your prototype: http://www.austinev.org/evalbum/

Thanks for your time,

Ben Robeson

I suppose we'll all need to buy new T-Shirts now with your new Record, eh?

On the new one you should leave the old printing and line it out, then put the 
new record under it. :-)

A 60w light bulb in series with the precharge limits the inrush effectively.
