I'm just telling you how it is done for ones that
will get good emissions results. While you are correct
that most small motors do make a fair to large amount
of pollution, it doesn't have to be that way. It's
like saying all cars are slow because VW bugs are!!

I do it because it is doable. I'm a fairly lazy
person and don't do things that might fail as it's too
much work.
But luckily I have experience in many fields that
allows me to see, do things others can't. A product of
not working 9 to 5 but instead on what I wanted when I
wanted, mostly building cool things ahead of their
time. I never settled for normal which is good as a
normal person would never try to produce EV's!!
Like when I started building multihulls I was told
they were unsafe, couldn't go to windward and couldn't
be built from 2 flat 6'x32' sheets of plywood into a 3
dimensional compound fair curved hull. Yet I've built
over 50 of that style boats and most beat racing
monohulls to the windward mark easily. And 2-3 times
the speed of them on other points of sail with a
liveaboard cruising weight load onboard!!
They said I couldn't build a windgen blade from a
single thickness and not only did I but it worked
better putting out more power and was quieter than any
other.
And that I couldn't make electric power from tidal
flow without dams but did and was so powerful it had
to be turned off 22hrs/day so not to overcharge the
liveaboard boat's batts.

If you have a spare $1-2k I will get you the
numbers and a unit, otherwise you'll just have to wait
until I get to that point as first I have to do the EV
part.
But I have studied this since a kid many yrs ago
and I understand it quite well and what makes a
difference.
I was fasinated by Detroit trying to make low
emission cars in the 70's and couldn't until they
finally figured out hotrodding, eff, tight
control,tolerances was the answer as is used now and
what I proposed.

So you 'prove' your case with gross generalities
and I give specific methods long known to science,
engineers and I get no credit for that? How do you
think low emission engines are made, Magic?
There is a bit of double standard here.
As for the eff, MPG, there are strong numbers to
back it up.
My E woody uses about 100wt-hrs/mile from the
plug measured costing $.01/mile. That translates to
10kw/100miles which also is what a fairly eff
generator makes from a gal of gas conservatively. With
top of the line small ICE and gen, it comes to about
13kw/gal so 130mpg equivilent.
If diesel top of the line with 90% eff gen, about
16-17kw thus 160+mpg equivilent. Lee says 20kw/gal in
the Prius but I'm more conservative and I don't think
he included gen eff.
And as the E woody was no where near optimized,
in fact, down right funky, I expect my Freedom EV to
do even better but conservatively will use those
proven numbers now.

To be honest, you don't seem to understand
combustion at all, instead seem to rely on gov
satistics of motors that I wouldn't use without
modifying a lot.
Have you ever noticed that when racers modify their
engines they can get twice or more power from them? It
is no different if you tune for low emissions but you
refuse to recognize that for some reason. All getting
lower emissions is is tightening up the tolerances so
everything gets burned correctly.
Maybe someone else can.

You are just like the other 'experts' who are stuck
on their ideas that something can't be done and refuse
to acknowledge the glaring flaws in your arguement
like the complete waste of a whole other car!! Which I
then go my merry way and do it as I will.
It reminds me of those who say EV's won't work. Not
only can they work, but with a little thought, design
work and being practical, not dogmatic, beat the pants
of a reg car in every way. It's call good engineering,
design.

I put out facts based on science, if you were more
of a scientist, you would understand better.
It's amazing that you put up such an arguement
without knowing anything about the subject of
combustion, emissions and how it works.
> I'm really sorry if this annoys or disturbs you.
Actually I don't mind as it gives me a chance to
educate others on the real facts as I have in many
other cases like smaller, lighter, aero, 50% batt
weight EV's are where it's at. Not leadmine
conversions that use 2 to 4x the energy, costs, to do
the same thing. Now that's eff, low polluting ;-0
All my life there have been people like you telling
me it won't work and I just shake my head and chuckle
knowing you, they will find out soon enough.

With science, physics, you don't need luck, just

ignore naysayers.
