There's no shortage of Bluetooth GPS receivers
out there, but Taiwan's Transystems seems to think there's room for at least one more, hoping to sway would-be users in favor of its i-Blue757 unit by sweetening the deal with some added solar power action. Supposedly, the unit's battery will give you a full 26 hours of juice on its own, or up to 100 hours of use when backed up by the attached solar panel (in direct sunlight, of course), taking just three hours to refill after you've drained it. How much good all that staying power will do you when it's tied to your comparatively less long-lasting laptop or PDA is another matter. Apart from the sun soaking capabilities, the unit appears to be a fairly standard Bluetooth GPS receiver, with a 16 channel Nemerix GPS module at its core and weighing in at a relatively lightweight 3.7 ounces. Exactly when you might be able to get your hands on one, however, (or how much it'll cost) remains to be seen.
