I just came across this great item on The Unofficial Apple Weblog (TUAW): a solar charging case for the iPad, by Voltaic. It will charge an iPad in about 10 hours. Apple is working hard at making the iPad a “post-PC” device, and with iOS 5, an iPad will no longer need to be tethered to work. Take away the need for electric to recharge the device, and add a 3G enabled iPad, and you can literally go “off the grid.”. The challenge has been the larger power needs of the iPad–but this charger meets that challenge.
At $299, the case/technology is still too expensive–once it reaches the $100 mark, I can see the potential for this product–I’d buy one!
