What is the best eco-friendly kitchen gadget?

While there is obviously no one answer to this question I will tell you what one of my unexpected favorites was - a seltzer maker from Soda-Club Home Soda Makers. It does not need to be plugged in, the bottles are reusable and recyclable, and the seltzer tastes great! I liked it so much I bought it for my mom for her birthday. I drink a lot of seltzer and was feeling guilty about all of the plastic and the fuel used to ship water. I did not know that things like this exist and I am totally addicted. While it is an unconventional gift it is a great option for fizz lovers.
