Solar Handbags and Back Packs
Solar handbags and back packs are advantageous over solar clothing, in that (of course) you don't have to wear them. Walking or hiking out in the sun, your fabric integrated solar panel can be used to soak up the sun's energy and provide free energy or backup power.
The solar bag from Solar Style, Inc. retails for about $200, but it will pay for itself in a year. It will charge a 600 mA (mega amp) battery in three hours, any sunny day. This is certainly big enough to charge your cell phone but not big enough to charge your laptop.
The solar backpack is another possibility for charging small electronic devices such as a PDA or an iPod. It's the perfect solution for those times when you're biking or hiking for several days and can't do without your e-mail or your tunes.
As with other solar technology, the development of progressively thinner solar cells will make nifty little gadgets like these more versatile and useful in the future.
