Robert,

You may have *tried* to answer my question, but you did not do so, because
you did not have the knowledge to answer the question.  Instead you offered
your own opinions and speculation on peripheral matters.  Chip Gribben, on
the other hand, *did* answer my simple question, simply and directly, as he
had the specific knowledge to do so and was good enough to share it with us.
No disrespect intended to you, however.  And nothing personal, although you
seemed to take it personally.  If you choose to leave this list, that's your
choice.  Whether you blame that on me, as you seemed to imply, is of no
concern to me, certainly nothing I would give a second thought to.
Hopefully you will choose to stay around a while and continue the learning
process that all of us are engaged in.

Merry Christmas,

Charles Whalen

Oh yes, the compound engine. I saw interest by the millitary in a compound engine version of the rotary for tanks.
 
I had also asked about that one and Moller said that it wasn't thier submission to the miltitary.

Very Interesting.
 
Likely totally useless for a 700lb car needing less than 10kw to run on the freeway.

Please, folks, enough of the bickering.  Stick to discussing EVs and stop
making personal comments.  That includes responding to personal attacks,
either real or perceived.  If someone insults you, the best response is none
at all - put him or her in your mail filter and forget him.

Bad enough that I'm wasting bandwidth on this, and you shouldn't be either.

Thanks.

Since we have not seen the contract that *they* received
from GM, we can't judge if the "do not even use on private
roads" is really in the contract.
That seems odd, though. How are you supposed to test if the
modification of a car is working if you can't take it to a
(private) road or track?
Only drive it off-road????
Serious - there is no fun in running a car only indoor or
even simulate its track capabilies on a dyno.
Note that the recent discussion about the EV1 contract
brought me to dig our Chelsea's email pointing to another
contract that does not mention "roads" at all.
Just that they do not sell or transfer ownership and that
they do not try to make it run as the original EV1.
And the offer that GM will help them in scrapping it, yes,
I believe they have some experience.

I just spoke with Eric from the WWU EV1 resurrection team. He stated that they have not been threatened with a lawsuit. They did receive a phone call from GM reminding them of the agreement they signed when they received the gift not to run the car on any public or private road . They also mentioned that part of the agreement was not to mar GM's image. So It appears that Dave Barthmuss of GM was telling the truth when he stated: "No legal threats at all.  I know what our reaction was to the Western Washington University's vehicle being trucked to LA and making a brief drive at a local enviro event and in no way did it involve and threat of litigation." Anyway, I thought I would look into the truth of this matter a little more and squelch a possible fire storm against our buddies at GM ;-)

With a micorturbine though you are putting out horrible pollution. Kind
of defeats purpose of ev's or hybrids if you will pollute that much.

Remember as a general rule the faster and hotter the combustion chamber
dwell time the more pollutants emited.

That's why the old gas powered steam cars were such low polluters - the
oil fire was at uncompressed pressure and it dwelled in the combustion
chamber with the water steam flash pipes for a long time so complete
combustion occured.

this issue seems to suffer from the same niche vs mass production
problem where any available products are hard to get, extremely
expensive or non existent. at least turbine generators.
maybe a construction generator could be used if small in size. maybe
modified a bit to run higher rpm.
maybe you have to make one from an efficient turbocharged scooter or
motorcycle motor coupled to a rewound alternator or even AC Etek.

if strained a bit 10kW should be possible to do small. doesn't have to
last 100000 km. only once in a while.

Depends alot on what fuel you use, what cycle you use, and what you
define as pollutants....  alot of the microturbines use natural gas
which tends to burn alot cleaner than gasoline -- but is a brayton
cycle with natural gas cleaner than an otto cycle or diesel cycle with
natural gas?  Dunno.

The Capstone Microturbine is the readily available microturbine right now.

Its emissions are excellent, its noise level is supposed to be reasonable, something like a loud box fan rather than a jet engine.  It's got a build-in generator head and control system.  The Hybrid Vehicle version was used for a fleet of hybrid buses that were scrapped and some of the turbines went onto the surplus market.

At first it appears to have crazy high efficiency, then you see they're talking cogen, heating hot water with the exhaust.  Well, I could put an elaborate water jacket on any piston engine exhaust and get close to 100% efficiency too!  Bottom line is it's pretty good efficiency to electrical output, once you consider that its figures already include generator head losses which might be around 10% or more if you just hooked a generator head up to an internal combustion engine to make a series hybrid.

It appears it could make a decent series hybrid, well, it might be a few more mpg at best, or maybe a few mpg less than the original vehicle's mpg.  It'd be quite a novelty to have a turbine vehicle but it's not gonna stun the world with its mpg.

Well, so far I'm finding from the inputs that in the 10kw range, I'm only marginally better with something other than a Honda Genset or something equal to it.
 
I can find a Honda or equal new for $200 to $500 USD on Ebay and elsewhere.
 
At the balance of power/weight/Efficiency/Cost is there anything out there right now I should consider? I have about 3cu ft of space to work with.

> this issue seems to suffer from the same niche vs mass production
 
Yes every part of the vehicle I'm interested in suffers from that. It's a 'tween machine. To big for a Classic Velomobile or Cabinscooter, to small for a mini-car. Closer to a micro-car but too different to use those old style parts, if I could even find any to suit.
 
I am finding candidate parts in other industries. I just have to find them.
 
AT the moment, motors I want are used on Bikes, or Power tools or even those tread mill motors.
Same for the controllers, athough I'm having more issues with cost than availablity. What woud work is equal to about 2 or 3 DC Etek motors. And I could go with that.
 
The genset likely will be adpted from low cost home power units. I just need to adapt it for the voltage required.
 
Trannies used on LawnMowers or ATV seems possible, unless I use one motor for each front wheel.
 
My bigest limit seems to be a suitible CV joint. Most all automotive are too big except what is on a Zenn. I have no idea where they got thiers, and I'm affraid to ask what a Zenn CV assembly would cost.
 
Any ideas on that one?

the Zenn is a french made city car. you can presumably get parts for those.
how heavy is the vehicle and how frisky do you want it to be? the ADC6.7
L91 can push around a 1000kg car and I figure the Etek is about half
that power. so those two should cover a spectrum for your need for a
small car.

as for a honda generator, it's my impression that that kind of generator
has horrible efficiency. maybe because they run in near idle rpm where
the efficiency of the ICE is even worse than normal. worth doing the
math on if you intend it to run more than emergency use. I mean so bad
that it makes an 8L big block look efficient.
maybe it can be modified slightly to go higher rpm and give more power
at greater efficiency but might require alteration of the electronics too

The CV's on my Insight were pretty small compared to other cars I've worked on.

Also, you might ask these guys what they used?

Thanks for all the help!.
 
I'll look into these things in January.
 
As far as Gensets are concerned, I'll likely get something temporarilly. The best chance at the moment to improve sems to be the InfrRed, YZCrystal converter that WWU experimented with on thier Viking 23.
 
I'll have to contact them to find supplier contacts and designs etc. At least that concept is multifuel capible. It is compact, very light and overall that point may be the clincher. After all I can view it as only a range extender, so light weight is best for a deadweight emergency-only system.

Yeah, we've been over this many times, including running the numbers.

Basically, a consumer generator is an inefficient, noisy, dirty beast.  No sensors, fuel injection system, or emissions system.  No catalytic converter!  Much smaller than a car engine but that's not important- what is is how many hp-hr you get out of a lb of fuel.  And the genny's not really better.  Once you figure in the battery cycle, controller, and electric motor losses, it's gonna be worse mpg than a normal car engine.  But the emissions are the kicker.  It's basically on par with a 70's car engine; the emissions per gallon (or per mile) may be 10x or more worse than a 2007 car engine.

So, one has to ask what the goal is here.  If a "range extender" is only used 10% of the miles but produces 10x the emissions per mile, was a "green vehicle" achieved?

It is almost certainly illegal to run the genny on the street; it's the motive power and doesn't meet emissions by any stretch of the imagination.  Running it in the parking lot may hide your sin from the cops but not from your own conscience.

The 30kw unit I had sounded a little like a small quiet shop vac during
startup.  Not totally quiet, but not annoying, once it goes up in power the
frequency goes over hearing range and then it's just an "air" noise.

The units are designed for cogen, but can also have the recuperator running
which halves the heat and increases the electrical output.

There is one moving part, and it uses foil (air) bearings.  Once started
there is no wear.

The 3-phase gen head is also the starter, and the on-board inverter can turn
the 3-phase into any reasonable voltage or frequency from 0 (dc) to 3 phase
ac at 500hz (if I remember right).

It will only do full power at around 400-500v, but can run much lower. at
reduced output.

I definitely have thought of putting one in my van!

So are there any similar sized Genset with all the proper bells and wistles?
I like valid complaints but I love viable solutions.

Not really.  The Capstone Microturbine is the only one I found as appropriate (efficient, low emissions, not noisy as hell).  A 10KW isn't even big enough really.  For one, consider that you can't get 10KW of DC charging off of a 10KW AC generator, there's a power factor derating here.  And if it's supposed to average out as you start and stop, the energy's flowing through the batts so batt cycle losses apply thus you won't get 10KW average to the controller.

So unless your kwh/mi usage is very low, this may only maintain the batt's SOC at under 30 mph.  You will have to use it to charge while parked so it won't enable you to drive across the state for example.  I don't know your kwh/mi but I suspect a 20KW may be necessary as a minimum if you wanna use this as an unlimited-range series hybrid.

What must be kept in mind is 10KW-20KW gas or diesel worksite-type generator running at full throttle is a noisy, smelly beast that will DEFINITELY attract the attention of anyone within 100 ft as you drive by.  The noise you might have heard from such a genny at idle is not what you're gonna hear at full tilt.  You will need hearing protection at 5-10 ft for a prolonged period.  It is also probably illegal to drive a vehicle off such a gen because it's equivalent (probably worse) to taking off the cat and emissions system off the original engine.  

Now people convert their trucks to carb and remove the cat sometimes to beef them up and it's still legal in some locations.  But you're sure gonna get noticed as a more obvious case- and not the good kind of attention.
