Solar power may be making great strides in mainstream usage, but energy efficiency doesn't necessarily translate to fiscal conservation. The "Ultimate Outdoor Webcam" by DigitalXtractions, for example, runs on the sun's rays but costs $450 plus another $150 or $250 for a solar panel, according to The Raw Feed. But here's the kicker: Not only do you have to pay those exorbitant prices up front, but you also must shell out $60 a year for a "data subscription" that includes Web hosting. We think we'll keep a USB port open for the "Volvex" instead.
