I saw a news story or show, can't remember which now, that showed a 
country, New Zealand, Iceland or someplace like that, who've determined to go 
totally green when it comes to electric cars. Instead of gas stations they 
have battery stations. The country requires that the batteries be standardized? 
I don't remember exactly how it works. But instead of stopping and recharging 
your battery, you swap out your battery with a fresh one. Much like you'd swap 
your propane tank for your back yard barbecue. 
I think this is a great idea. You're only there long enough to swap 
batteries. Hopefully that only takes as long as it would take you to fill your 
tank anyway. Probably would create jobs as well. Teenagers running back and 
forth swapping out batterie

 Yes that has been worked out. It was discovered that charging takes so long
 because the electrons have to cross a porous barrier and most of the time
 they bounce back because they fail to align with the opening in the barrier.
 Some guys figured out how to eliminate most of the misses so charging can
 take just a few minutes. Their new problem is figuring out how to supply so
 much current is such a short time interval.

 Coleman, among others, has a rapid charge screw driver that uses a big
capacitor in place of a battery.  IMS the trick here is having a similar
capacitor in the base charging all the time.  They trade the charge in
something like 90 seconds.  The down side is capacitors aren't as stable as
batteries.

Re: [CGUYS] Better than a UPS

I thinK this is a good time for some creative thinking about energy. As we 
change how we get and manage portable energy many old assumptions will need to 
be reexamined. If our cars start to run on big battery packs we need to 
consider how those get charged...


The  Peugeot 888 by Oskar Johansen in the 2009 Peugeot Design Contest is 
a small electric car that converts from small and high to larger and low 
depending on whether it's in the city or suburbs. It has solar panels on 
the roof to recharge the batteries. Batteries are getting smaller while 
PV panels are more efficient that they were even a year ago.


There can be battery exchange stations for electric cars that are mostly 
powered by solar cells [both stations and cars]. Home charging stations 
can also be powered by PV cells. For those not familiar with solar 
photovoltaic technology, you don't have to live in a sunny location for 
them to be effective, although efficiency declines in higher latitudes 
in the winter. During the winter, the energy can be stored in salt ponds 
until the sun returns.


Main problem with generating your own electricity is the power 
companies. When you need more power, you pay retail to the power 
company, and you must pay your bill monthly. When you generate excess 
power, you sell it to the electric company at wholesale, and the power 
company pays you whenever--could be six months later, because you're not 
big enough for them to be bothered. Getting paid wholesale price is 
business, but so is receiving payment on the same schedule as the power 
company charges you.

Unfortunately, solar panels on the roof are not anywhere near efficient 
enough to provide electricity sufficient to charge cars on a reasonable

garage, rain, snow and the like, all solar panels can do is supplement 
battery charging.  Of course if you for example drive to an outdoor 
parking lot and leave on a 2 week trip, my claims go out the window, but 
for daily driving, some other source is likely needed.


I also note that it's not size that's the problem, it's reliable 
capacity and ease of charging.  A battery the size of let's say a 
stacked washer-dryer would be quite useful for many households as long 
as the battery doesn't need special protection from heat, cold or a 
location to vent gases while being rapidly charged.  It would be more 
problematic for a car to have batteries that size.

the exchange might normally work, it would raise the cost of dealing 
with large capacity batteries.
The truth is that we need some method of rapid charging said batteries 
on the go.  Ten minutes charging for let's say 200 minutes of driving 
would be reasonable presently (not much longer than filling up with 
gasoline), but we as a nation don't have the electrical distribution for

We have many problems that re not going to go away right away.

Part of the reasons is that we have built infrastructures that are 
quite costly, and took time to develop.


Most of the off the grid power generation methods developed up to 
today are stand alone.


20+ years ago one of my members bought a brand new car and had it 
changed over to NG.  20+ years ago.


Problem is where are they going to refill their car on trips?

Schwans frozen foods delivery trucks run on propane.  Except for 
filling up at the shop where else are they going to fill up?


In order to have a system of transportation running off of alternate

Garden lights have cheap, usually poorly made, solar cells. If you bought them more than a 
year or two ago, they have NiCad batteries--cheap ones that are less than 500 milliamps, 
and low quality. The NiMH batteries in the new ones are cheaper and low quality. If you 
change the batteries in your garden lights to Duracell/Eveready/Rayovac 2000+ mA your 
lights will charge better and last longer, even on cloudy days [but the batteries might 
cost more than the lights.


Lithium batteries for heavy use are entirely different from NiCad and NiMH anyway--no 
comparison. Aside from cell phones and other electronics, they're used in cars and for 
storing power generated by solar PV shingled roofs.


We've been following the development of PV power and storage for over 20 years, but only 
recently has it become more affordable, thanks in part to the investment by the German 
government that encourages homeowners to install the solar shingles. Similar projects are 
in progress in Japan. In the US? For now, open your wallet and pay for it, unless you live 
in a state that can afford the tax credit.
