If you want to see loads of eco products, I recommend you buy 'the eco-design handbook (thames & Hudson) ISBN 0-500-28521-7 I’ve found it an amazing resource for loads of things green. In the back is a website resource. If you just want to see products then Inhabitat is cool, but if you want info for designing your own stuff, then It breaks everything down into specific categories. It’s difficult to give reccomendations but you could try some of these to get you started:
