For those who are interested in greening up their landscaping tools, I read on (an online green social network) that Black and Decker's NST2018 18 Volt 12" Cordless GRASSHOG Weed Eater/Trimmer is a great alternative. Two members just gave it glowing reviews, mentioning that it's light, easy to use and the battery back up extends the time you can use it in your yard by up to 30 extra minutes. If you charge an additional battery, then you'll have continuous weed whacking ability for well over 1 1/2 hours.

There's also an article posted on Greenwala about the fully rechargeable 36 Volt, 10-amp Neuton CE 6 lawn mower. It can tackle 5,000 square feet of grass in one hour of battery time before requiring replacement. Here's the link if anyone wants more info:
