Spanish take the lead

[Gordon Reeder]

OK they will quadruple, but at least less crap will be sent into the
environment. Then there are the silly lead acid batteries they use.
They pollute like mad in the production and disposal. Maybe the PV
cells could rive a compressor that charges an air tank that will be
sued on demand to supply electricity. The store medium will be
non-polluting air.

Wouldn't this be a grid tie system where the excess power
Generated would be feed to the grid, not stored localy??
Ergo, no Lead acid batteries.

Hey Dubya!
Unity means let's try to meet each other halfway

If they are the grid attached ones that feed back into the power supply
network (I've seen a few in various issues of HomePower) then there will be
no need for batteries. IMO grid attached panels are adequate if there is
mains available, the power company will allow you to attach them and power
cuts are rare. I didn't think lead acid battery's were very polluting if
they are recycled properly and not chucked in landfill? The compressed air
idea sounds a bit bizarre...

And exactly what information do you have to back that statement up?

One of the major concerns from eco groups and goverments was that the
so-called pollution-less fuel cell would move pollution elsewhere, as large
lead acid batteries would be needed in 100s of millions of cars. Ever seen
a battery plant. Not a nice site. And then there is the disposal of these
thing which have a short life span. In third world countries, and countries
not so third, the batteries would probably just be dumped - millions of
them.

PV systems use large batteries and inverters. Surplus is fed to the grid.
If the storage medium can be air the whole thing is vastly cleaned up.

Lets get REAL here, Ok? What is the Power density of an Compressed Air
System, in the MASS, and Size domains, as compared to the Power Density
of a Wet Cell Battery? You will find that there really is no comparison.
Batteries or ORDERS of magnitude above Compressed Air.

As has been pointed out to you, the United States has a mature battery
recycling system implemented. If you live in a third world country you
can improve the Earth by agitating for such a system where ever you live.

Have you ever seen a battery plant?

But once again you are not addressing exactly what the environmental
effects of increased steel production to build the "environmental"
devices would be. Please try to stay on topic.

A grid tied system would not need to use (large) batteries. You do know
what a grid-tied system is? Of course your failure to post a link to the
story greatly handicaps your ability to argue this point correctly.

Best not have them in the first place.

Yep. Awful sight.

[Gymmy Bob]

Well at least the last name is correct!

So once again you can't provide any evidence that what you say is true.

 

[Robert Morien]

Pointing out a simple fact to you is not an attempt to make friends with
you. And you have me mistaken for someone else. This isn't surprising as
it's clear you don't pay much attention to any of the posts.

That's cute. but no cigar

 

[Robert Morien]

Best not to replace them with a totally inadequate system that is more
dangerous.

Yep.

Where? Have you seen the recycling system for batteries in the US?

 

[Gymmy Bob]

It is a system that is tied to the commercial electrical grid, with or
without batteries, that generates a voltage syncronized with the grid
voltage.

Lead-acid batteries don't just get dumped. Anybody with a lick of
sense recycles them.

Well, I can see a few getting dumped, if they expire at the far end of
a long supply line, and the cost of transport/collection is too high
relative to their value as raw material. In any area where they wind
up being used in large quantities, though, this would be unlikely.

If lead-acid batteries are handled properly, the lead is in a closed
cycle, and does not leak into the environment.

Look in the header information.
"news.uni-berlin.de"
He is from Berlin

No, that is where news.uni-berlin.de server is from. That could be a
free account on the news.individual.net server. I have one. But I
usually don't post via that account. Too painful.

When I originally got my account several years ago, I read the terms of
use as they pertained to posting and determined it was too painful. I
haven't bothered to check since, and I don't recall the terms, only the
result. I thought it might have had something to do with requiring your
valid account name and/or e-mail addr to show in the headers, but
judging from your post, that must not be true now.
