 Solar panels are getting cheaper and gadgets are getting less power hungry. It's easy to see where this is headed, and Justin's post is only an early example. via TreeHugger

Such an item might seem silly if one is not the camping sort. If it could charge a laptop, then it could also charge cellphones which could be necessary out in the wild. There are times when the weather is too outstanding to spend the day inside. Besides, one can always stick this panel in the window while one stays in the shade.

Solar chargers: If you realize that AA cells are just about taking over the world, and this size charger can charge a couple of AA's in a day's time (mostly)- For the cost of a charger and a couple of sets of Lithium AA's-you might go five years before you need another set of batteries. At the co$t of alkalines, that's cheap.
I wish there was a really good source

You can find this stuff here and there ....on ebay...in home depot...at the grocery store... but I wish there was a really good single source....a Solar Depot...Where best avaiable stuff could be found and prices and quality could be compared. Eco-entrepreneurs where are you??????

Great idea Marti, when it's set-up please make sure to make shipping to UK an option, please!
Solar power heating the globe?
written by Kriss , September 04, 2007
does anyone know if solar panels absord the heat of the sun or reflect it? If I am not mistaken, help me here, reflecting the sun's rays actually increase the surrounding temperature. Trees and other plants, they absorb the sun's enery and that's why without them, as in urban areas, its hotter? Say, if every roof on every house, had solar panels on them, would that increase or decrease the surrounding temperature?

Solar Power Explained
written by solar-sails , October 12, 2007
Power is measured across a gradient. For instance, the opposite ends of a AAA battery. Solar panels accumulate photons which push charge from one part of the panel to another, creating a gradient from the force of the Sun's radiation.
The most efficient solar panels will absorb and transfer to electricity the maximum amount of sunlight. Let's say that is powering a lightbulb. Now, the panel absorbs light and heat and converts it to electricity. The lightbulb uses the electricity and puts out light and heat. Here's the interesting thing. You need lightbulbs mostly when the sun is down. Also, a bright sunny day is an inopportune time for running a color laptop screen off battery power.

Marti, check out http://www.SolarCoupons.com, its a place where you can find all sorts of great deals on every kind of solar product you can imagine! Better than a solar depot if you ask me.

This is a nice thing to hear from the youngsters and I suggest taking advantage of some SBA Loans: http://www.onlinecheck.com/bus...oans.html
, loans can help you buy some expensive solar gear if you think this will help you.

I looked around the site, but I couldn't find an option for getting a panel to charge my laptop. I've been looking for a solar panel to charge my laptop for a while, preferably one that I can easily get from Australia (I live in Perth) - any ideas?
What about cloudy days?
written by Appliance Parts , March 13, 2008
I guess that charger's pretty ok if you live in Cali. Otherwise, might be pretty worthless. Still a brilliant idea and also affordable. Good for camping trips, too.

Solar power may become the next fashion world wide when it will become cheaper and easier to get. I see the future as described in sci-fi movies where you can see large solar panels everywhere.
Free Computing!
written by Uncle B , April 12, 2008
I just have to find a cheap 2nd hand electrically efficient laptop, erase the programs on the hard drive, not to offend the Microsoft licensing agreements, Install Ubuntu, buy a second battery pack, and a solar charger like this one and I should have the cheapest eco-friendly computing possible until the end of time!

Solar power is still expensive and does not provide that much help anyway. It will probably develop in the next 10 to 20 years. After that gas will long be forgotten as a propulsion method.

Solar Small Device Chargers
written by John , June 21, 2008
Several small device solar chargers as solar style, solio Icetech, and Power monkey can be used day and night. They contain on-board batteries that can be charged with the solar panel and with AC.
But, there are big differences in these chargers as pointed out at sunjoules.com/page/47122202

An interesting direction (well to me, anyway) in solar research: The Mars rovers have solar collectors
that are far more efficient per square meter than ones commercially available now because different layers absorb/create energy from different part of light's wavelength. Unfortunately, current production costs are in the millions. Since mirrors are significantly less expensive than solar collectors I'm wondering if anyone has looked into using fewer solar collectors paired with mirrored surfaces? What effect would the added heat on the solar collectors have (e.g., longevity, efficiency, etc.) ?

Science, technology gadgets and...baby seals. We're in a bit of an eco-mess, but we've got the brains to lick any problem. And that's why EcoGeek.org publishes up to ten stories daily about innovations that are saving the planet.
And if that sounds interesting to you, then congratulations, you're an EcoGeek.

It's worth suggesting that this is good for slow charging batteries in bicycles and cars than pitching it to make people stay under the sun using their computers.
