Numbers Just Aren't There To Continue With Internal Combusti

Hybrids provide false efficiencies. You still have to burn
something, cut across the power grid, charge a fuel cell/battery...

Much electrical power in the US is green hydroelectric. ďż˝(Indonesia is
pure red, though.)
High efficiency requires the economies of scale of large power plants.

Small adiabatic engines are inherently dirty and inefficient.


Bret Cahill
 
The most efficient power plant on the planet is a natural gas fired
industrial gas turbine made by GE -- 60% efficient.

It's down hill from there as far as efficiency is concerned so a few
points increase is a farce when compared to the impending 1000+%
increase in fuel prices.

The only way to go is hybrid electric with electrification of major
highways.

Do _not_ give automakers any bailout money unless they agree to go
completely hybrid.

Bret Cahill

Hybrids are uneconomic. You'll push them even faster into
bankruptcy. Liquid fossil fuels win on *weight*. Energy per
unit mass is the lowest.
Hydrogen is the best fuel, and the best way to store hydrogen is to
stick it to carbon.

John

Absolutely.
I suppose LNG is the ideal low-carbon fuel, assuming you have
something against carbon. C(n)H(2n+2) works best when C=1.

John

The only problem is the distribution network.

And the storage problem...

I'd think it tractable. After all, we use it
today for home use.

And the efficiency issue (ICEs still run with low efficiency on nat gas)

They do about as well as ICEs will ever do. A diesel turbine
runs about 60% - not bad as these things go. I'm not sure 60%
is a figure that can be sneezed at easily. Gas turbines
approach the same 60% figure.

And the supply issue (we don't have enough nat gas to supply a significant
portion of the vehicle fleet on nat gas.

Not familiar with this as a problem. Gas is - today - quite
cheap. No doubt the demand would shift radically. It seems
to be at least a potential supplemental source.

And the cost of conversion.
And then you still can't do regenerative braking..

Not sure that's all that important...

Maybe hybrids are not that bad after all.

Hybrids provide false efficiencies. You still have to burn
something, cut across the power grid, charge a fuel cell/battery...

If dollar-efficiency per mile is halved, then why wouldn't simply
enforcing $4 per gallon gasoline be simpler and even less painful?

And hybrids cost as much as *ten(ish) times* as much per mile.... a
Scion xB? $0.48 versus a Prius at $3.25...

There's just one whale of a lot of infrastructure invested
already in ICEs. Now, if you're timeline's 20 years, then
lots of technologies must be considered.

But I don't think you can substitute any action for higher
fuel price. It's the only way to inform people of what they
right decision will �be.
I'm not sure how Big Oil continues to distract everyone from the 8000
lb gorilla but everything including vehicle cost and infrastructure is
small spuds when compared to the impending 1000+% increase in fuel
prices.

Hybrids were introduced for reasons that won't be nearly as important
as the fact that they can be powered from the grid, either by
batteries or road electrification.

That's a co-gen one too. �Not very portable either, kinda big too.

At 100 tons maybe on a ship but not for yer pickup or SUV.

Whoops I meant to say Combined Cycle, not cogen
http://en.wikipedia.org/wiki/Combined_cycle

basically it's a steam engine downstream of the gas turbine

sure, if you want heat, collect all you want from the tailpipe

MAN and Warsila-Sulzer do better than that. The heat collected from the
exhaust generates steam which runs turbines that can produce MORE
electricity. Then the remaining 'waste heat' can be put to good use.

If anyone was serious about energy efficiency this would be used in district
heating schemes. They do it in parts of Scandinavia. It's proven technology.

We got more than a heat engine efficiency problem. We got a _no_
energy problem.
Don't be silly. With that level of efficiency, existing oil reserves at least can
be extended to hundreds of years. Plenty of time to work out Plan B.


That's why we need to go electric.
Where's the electricity going to come from ?????

Petrol mode just means that there is a generator supplying
electricity, which is the case in series hybrids of all kinds.

My statement "The wheelmotor platform is the optimal implementation of

works well or not, and it doesn't mean that developing better
batteries isn't necessary. Think in terms of trading their sports car
performance (or Tesla's) for a bit more mileage though.

If you have the control systems and software they describe, and it is
possible to get maximal regenerative braking with supercapacitor
storage, you maximize the amount of energy from the energy source that
gets converted into *motion*, which is the whole point eh.

There are lots of other advantages besides eliminating transmission
losses, like the weight that goes with all the mechanical parts, and
the fluids as well. You will have nice handling and stability, and if
you have an 'engine problem', you will be able to swap it out like
changing a tire. Well, if you are pretty strong of course, but you get
the idea.

But my point is that there is no incentive for any auto company to
build something along these lines because it cuts into their profit
system, and dealer repair business and so on, and so some entity---
maybe a DARPA or maybe Bill Gates or some consortium---has to create a
new 'car company' to develop and market based on this concept.

If there is going to be a 1000% increase in the price of oil and gas then
the output of current algae based biofuel methods would be insanely
profitable. And this does not require a total destruction of the American
way of life or the centralized big brother crap associated with
everything needed for the electric car. I am all for hybrids as a way to
move toward nuclear power. But make no mistake. That is where you are
going.

This topic is going to get you into nothing but serious trouble with
the fossil fuel Mafia cabals and cartels.

Don't forget about green/renewable energy that's making affordable H2
and h2o2, not to mention helping to create nifty synfuels (including
out of CO2). There's also thorium reactors that'll give us clean and
failsafe energy at 10% the birth-to-grave cost of conventional nuclear
energy.

the electric car" has nothing to do with whether this particular thing
works well or not, and it doesn't mean that developing better
batteries isn't necessary. Think in terms of trading their sports car
performance (or Tesla's) for a bit more mileage though.

If you have the control systems and software they describe, and it is
possible to get maximal regenerative braking with supercapacitor
storage, you maximize the amount of energy from the energy source that
gets converted into *motion*, which is the whole point eh.

There are lots of other advantages besides eliminating transmission
losses, like the weight that goes with all the mechanical parts, and
the fluids as well. You will have nice handling and stability, and if
you have an 'engine problem', you will be able to swap it out like
changing a tire. Well, if you are pretty strong of course, but you get
the idea.

But my point is that there is no incentive for any auto company to
build something along these lines because it cuts into their profit
system, and dealer repair business and so on, and so some entity---
maybe a DARPA or maybe Bill Gates or some consortium---has to create a
new 'car company' to develop and market based on this concept.

Well, Darpa certainly isn't going to do it. Since they work with
battlefield technology.
It seems that the military is actually a leader in adopting electric propulsion and hybrid electric vehicles :
