would the sky satellites batteries run out?

http://www.darvill.clara.net/altenerg/solar.htm\n\nThis is a favorite source of future energy for many people, comforted by the thought that it is unlimited. But, quite the contrary is true. The Sun will exist for a long time, but at any given place on the Earth's surface the amount of sunlight received is limited--only so much is received. And at night, or with overcast skies, or in high latitudes where winter days are short and for months there may be no daylight at all, the sunlight received is very limited at times. Direct conversion of sunlight to electricity by solar cells is a promising field, but the amount of electricity that can be generated by that method is not great compared with demand. The conversion efficiency is low, about 12 percent with present technology.\n\nSolar energy in quantity requires huge installations. It has been estimated that an area of 60 square miles in relatively clear central Oregon would have to be covered with solar cells in order to meet the present electric needs of that State. About 10% of the cells have to be replaced each year. But the big problem is how to store significant amounts of electricity when the Sun is not available to produce it. That problem remains unsolved. The statement that "solar energy will not make next century's electricity" is probably right. And the end product is electricity--a very limited replacement for oil.

this is an 11 year cycle of our sun. it will start revving up around 2008 and should peak around 2012.  we have had them in the past say about 22 years ago. If it dose happen the thing we need IS solar panels.  because the transformers on the planet will be taken out by power surges of the sun and we will be without power for as much as 10 years while they rebuild them. (we really need alternative energy then) but i really don't think it is something we really need to worry about.

Well, if you can't even spell "solar" I doubt you would have the skills to mount and solder more than 2,000 4"x4" solar cells together, add blocking diodes, and wire the whole thing up in a weatherproof frame without breaking about half of the delicate little buggers.  If you need that much power, you're not going to save much of anything by trying to build your own.  Buy some ready made.

Yes, for a short time. There are various materials and elements here on Earth that give off their own luminosity. However, very shortly, thereafter, we would freeze to death.

satellites.\n\nfor sure

If we were batteries, sleep would be our recharge.

I would guess it would include old solar panels and various pipes, etc. that no longer function.  There would also be industrial waste from the manufacturing of this material (air pollution, water pollution, etc.)

No. However, it will make the battery last a tad longer than if you left it out at room temperature. \n\nBasically, your battery is storage for electrons. If you just leave a battery out, those electrons will try to ground themselves (leave) from the battery. The more you lose, the less enegy there is in the battery. Most smaller batteries are dry cells. The free elctrons are formed from chemical reactions within the battery itself. \n\nPutting batteries in the freezer will not re charge it, but it will slow down the chemical reactions so that not s many electrons are wasted. \n\nSUMMARY: Freezing your batteries won't recharge it, it will help them retain its charge if left un-used.

More dependent on it!\n\nAlso, I imagine it available EVERYWHERE...satellite like and CHEAPER!

That's not renewable. You just demonstrated that perpetual motion is feasible! Hello Nobel! Can I get in on this?

The sun does go through an eleven year cycle where sunspots and electromagnetic storm activity peaks every 11 years or so.  I don't know if it's getting stronger every time, though.  It does affect mankind more every cycle, but thats because we have more and more satellites in orbit all the time, so there's more hardware to be affected.  It won't cause too much trouble on the ground, though.  The Van Allen radiation belts and the ozone layers block most of it.  Mostly it would affect communications, and cause radio static, etc.  I wouldn't get your knickers in a knot over it.

Yes, absolutely. No binoculars or telescopic equipment needed. They normally look like fast-moving lights - a bit like a plane except (normally) no flashes. When they reach the Earth's shadow they disappear quickly, so it's normally best to look for them after dusk or an hour or so before the dawn. Log into the website below with your current latitude and longitude coordinates and you will be able to predict where and when a satellite will be visible in the sky. It's not unusual to be able to spot 5 or 10 satellites on any one night. \n\nThe International Space Station is particularly bright when it passes over. \n\nSpecial satellites cause what is known as an "Iridium Flare" which is so bright you can see it during the day. You'll find more details about Iridium flares in the website below.

They are light which has obvious advantages, but they do not do well in cycling temperatures and have a lifetime that is independent of how often they cycle. As such they would not be useful for any long life (> a year or two) space application (which most are since launch costs are so large), though I suppose a system that would need to cycle the batteries frequently (say periodic bursts of power fairly often) they might be useful.\n\nI guess they would be useful in a launcher because of the weight savings.\n\nThey are pretty new to the flight qualified scene and I don't know much about them so the above is speculation.

Negative.  The more minutes used, the weaker the battery.

WASHINGTON -- While astronomers predict only a minimal blast of dust debris from comet Tempel-Tuttle for the Leonid meteor shower this week, some spacecraft controllers are on standby alert.\n\nFor the past two years, measures have been taken to protect Earth-circling satellites from the Leonids. High-velocity particles can wreak havoc with spacecraft, damaging solar panels, as well as delicate sensors. \n\nHits of speeding comet debris can also spark electrical effects in a satellite, possibly causing control thrusters to accidentally fire.\n\n[uplink]\n\nThe potential severity of the Leonid shower in 1998 and 1999 spurred a number of precautionary action items for satellite ground controllers. \n\nSelected satellites and components were powered down. "A team" personnel took over consoles during the showers. And a number of spacecraft solar panels were adjusted to minimize exposure to incoming storm debris
