A lot of people get Car batterys and an inverter they can clip on to them.

I've seen them used to power lights, credit card machines, etc... Depending on how much draw you are putting on it the battery should last a whole fair day, or night if you are just using it for some low wattage/draw lights... Though you will need to find a place to recharge it.

Typically my campers lights will run off my battery for a six week run at Northern without needing a recharge as long as I turn them off when I am not at the trailer...

If you're just lighting, try looking for little battery powered push lights. They hide easily and light up fairly well, leaving just enough darkness to not be obtrusive.

At Bristol I saw a permanent shop that had a small overhead fluorescent light over their counter that they just covered with a piece of fabric but they had a regular electrical hook up.

There are also solar trickle charger panels designed to help recharge "deep cycle" batteries for RVs. A car batttery is mainly designed to give a quick jolt to start the car. Deep cycle batteries are used for back-up power, or powering lights in RVs and are intended to be run down and recharged Here's a faq page discussing batteries www.windsun.com/Batteries/...ery_FAQ.htm

There's also some neat backpacks and things being made with solar panels
ecogadget.net/2007/12/12/...d-backpacks/ I wonder if some of these might work to power some of the low wattage LED lights that are coming out.

Yeah, my friend Foxfire told me how he used solar panels he hooked up to marine batteries and ran his electricity off that.

I am going to look into these other suggestions as well!
This is something I need to figure out asap too :)
Thanks
