last month,my 1BR apartment used 330 KWH. add 10KWH every night(worst case

then there are multiple car families.Dad's car,mom's,1 or 2 kids cars...
and most apartment complexes aren't going to be able to add charging
stations,without great costs.

He's a radical thru and thru. IOW, he's ONE OF the envirowackos. And
we don't need a freakin' storage facility. We need to reprocess our
waste and use it over. We're doing virutally everything wrong that we
can. The envirowackos want it that way, because they're
anti-capitalists, and are attempting to wreck capitalistic economies.
And they're succeeding, because virtually no one recognizes the threat
for what it really is.

We have vast oceans of natural gas. It is really amazing how much we
have. We just have to drill it. There's at least 100 years of known
natural gas in the US, and then of course there's coal gassification.

OK, how much is that gonna cost ya? How much gasoline expense goes
away because of it? My electric for last month, at about 600 KwH if I
remember right, was something like $70. If it doubled, that'd be
$140. A tank of gas is about $35 - $40 in my car, and I bought about
12 tanks of gas last month. (I get around...) That'd be a whale of a
savings for me.

I don't see the problem. Sure they are - the electric company is just
going to have to wire up the place for more service delivery.
Fortunately, the day of everyone having an electric is far in the
future, so they have alot of time to do that.

We have to defeat them, its that simple. The 1st step is making the
public aware that the envirowackos aren't about the environment,
they're about harming capitalism. That's their true goal. While I
often entertain pessimism on some things, I'm optimistic that these
people can be foiled in their attacks on America.

>The concept is being tested by several states RIGHT NOW.


"The right of the people to be secure in their persons, houses,
papers, and effects against unreasonable searches and seizures, shall
not be violated..." Amendment 4. Tracking someone is an unreasonable
search, and would require a judge's approval. So far, the ninth
circuit court doesn't think so, but it is expected that the supreme
court will formally say that the cops can't come on private property
and attach a GPS to a suspect's car without a court order. To do it
to non-suspect citizens should be even easier to refute.

And, of course, it just doesn't work, because it is too dangerous to
allow the information to exist in some cases. My buddy was working on
the A-12 attack aircraft before it was canceled. Even the meetings
were secret as to when and where. He couldn't afford to have such
tracking info exist, lest the Russian spies of the time were able to
access it and learn what contractors may be involved and so be able to
target their spying.

You just can't be tracking people, for lots of reasons.

Tolls are being collected at full speed, no slowing down on several

Not me. I'm for electric vehicles, which will make the nation's
transportation costs plummet. Electric vehicles are about 3X more
efficient than their internal combustion counterparts. Our great
distances that we must move things are one of our inefficiencies that
make the US at some disadvantages to dense anc compact places like
Europe. To mitigate that costs is to mitigate our disadvantage.

So, make sure you have enough when you start. Its like filling a tank
with gasoline.

You'd be surprised what can be done when a buck is to be made. Sure
they can do that. And, these service stations will likely be operated
by your power company, which will use a portion of those batteries to
feed power back into the grid when it is needed. They will likely
have 3X or more batteries than they need to service electric cars and
trucks. The ones that aren't going to be needed immediately are going
to be mitigating the big bug-a-boo of solar and wind power, which is
the sun not shining and the wind not blowing. At those times, these
batteries will be filling in for home electricity.

Probably robotized. The cost of electricity is a whale of a lot less
than the cost of gasoline, or alcohol for that matter.

The original post of this thread appears to have solved the "far"
part. Its only a matter of formuating a standard for being able to
change out batteries quickly and easily. The batteries might even be
agreed to be cylinders the size shape of a very large D cell, at, say,
30 lbs. You could change it yourself at home if it came to that.
Maybe there are 20 of them in your vehicle. You'd just have to be
able to jack up the vehicle at home to get at the batteries.

>EVERY electric vehicle made today and for the near future is being designed
>with a built-in pack,not designed for quick-change.


One thing at a time. That sort of standarization is in the future,
where it makes the most sense to be. We don't have enough electrics in
existence to be thinking about doing this yet. Most are still
hybrids. We're just now getting cars that are made as electric-only,
and they mostly only go 100 miles or so, and are not really candidates
for long-distance cross-country travel where this mode of recharging
would be most in demand.

They'll just have to change that.

A LOT of their freedoms. Good healthcare, for one. Yeah, they get
so-so healthcare to ALL the people, and the ones that are poor here
and can't afford it here and die here make their AVERAGE numbers look
better than our AVERAGE numbers. But if you have a life-threatening
disease, and CAN PAY FOR IT, you want to be here, not there.

For instance, there is a surgical machine known as a Da Vinci machine,
used to remove small cancers in breasts, prostates, and other internal
sites. These have a great advantage of very quick recovery time and
way less trauma and a smaller set of scars than regular operating
techniques. I live in Virginia, and can tell you that there are 88
surgeons in the state of Virginia that can operate one of these
machines. In all of Canada, one of these socialized medicine utopias,
there are only 66 surgeons in that whole country that can operate that
machine. Where do you want to get your cancer removed? Here, or
Canada, or maybe Europe? I got a prostate cancer removed on a
Tuesday, and went to "Indiana Jones and the Crystal Skull" on Friday.
Try that with an "open" surgical technique.

That's a lotta envirowacko BS. There's PLENTY of oil. There's 3X the
amount of the Saudi reserves in the shale out west, and there's an
unknown, and likely vast amount in places where anti-capitalist
envirowackos have blocked access to exploration in Alaska. The
envirowackos who are trying to destroy the USA as a capitalistic
country are also attempting to get the shale oil so that it can't be
mined or drilled either. They are currently winning, and the country
is in danger of collapse. We just have to defeat the envirowackos,
and things can get a lot better.

Oh, really. There are 250 million privately owne firearms in this
country, and, well, we're just going to have to see about any

be a lot of foolish invaders. There will be a point where the

More envirowacko BS. This has already been shown to be wrong and

350 years. Hey, the climate changes, all by itself. Learn to live
with it, or die.

OK, but I'd like a little more technical explanation that I can read,
that says how they're actually doing it. Nanowire battery? Both
anode and cathode? There's a team from Stanford that is supposedly
working on this, but is this their battery, or some other battery.
Inquiring minds want to know....

200 kWh? For a practical automotive environment with 1000+ cycles,
rapid charge and discharge? No "maybe" about it. It's BULL****.

200 kWh is hardly comparable to the energy available in the fuel tank
of a conventional motor car. You're looking at the nett energy from
about 45 litres of diesel fuel being used in a modern, turbocharged,
direct-injection diesel engine. 200 kWh that in that form takes a
minute to "re-charge" and weighs about 36kg.

Batteries with that nominal capacity will be at least 10 times the
mass and volume; making man-handling unfeasible.

Electric motor vehicles need to be functionally and financially
competitive with existing technology before they are accepted.

It is highly unlikely that the mode of energy storage to make it
viable will be electrolytic. Cathode and anode materials are at the
limits of potential. There aren't going to be huge leaps in
performance; just tweaking.

You prove once again that you have no sense of proportion.
That is a common problem with fanatics.

Wind and solar aren't viable to begin with. So no question of being
"more viable". That's like asking which of the ugly sisters is more
beautiful.

I have previously demonstrated that the amount of energy required by
such "filling stations". Each will need to have a small power
stations; probably nuclear because a grid connection supplying the
required energy means a whole new grid infrastructure.
