" Energy Star The FreeCharge Weza ($269) is a portable battery and generator that relies on elbow grease. Make that ankle grease-stomping a step pedal cranks the generator and charges the battery. (It also can be juiced up with an AC or DC adapter.) The unit&amp;#039;s 400-amp max output is enough to jump a car, but, with a cigarette-lighter adapter, it can power dainty devices like cellphones and laptops too. As an emergency power source for the home or a backup generator for camping or boating, the Weza is a step in the right direction. INPUT  Step pedal:  100 steps per minute generates 25 to 40 watts.  AC/DC:  Charges from a wall outlet, a car battery, a solar panel or a wind turbine. OUTPUT  DC adapter:  A 12-volt DC cigarette-lighter adapter delivers power to devices such as laptops.  Jumper cables:  66-in.-long cables deliver the juice.  Weight: 17.75 pounds  Battery: 7 ampere-hours (Ahr) sealed lead-acid  Discharge rate:  400 amps, cables;  10 amps, adapter If you&amp;#039;ve seen one box cutter you&amp;#039;ve seen them all, right? But you probably haven&amp;#039;t yet glimpsed the Lenox Gold Utility Knife ($15), which uses a titanium coating on the nose and the blades. Sure, it&amp;#039;s gaudy and expensive. But, it also keeps the knife housing intact and the blade sharp enough for many hours spent cutting cardboard boxes and thick carpet. lenoxsaw.com "^^<http://www.w3.org/2001/XMLSchema#string>
