With all the carbon calculators there are today on the internet, you got to wonder what's the purpose of a stand-alone gadget that measures carbon footprint. But, if ever you do need one someday to obsessively compute your carbon footprint on the road or something similar, Japanese company Frepar Networks has one. And guess what? The company went all out--the solar-powered carbon dioxide calculator is even colored green.

There are numerous options to key in that are related to everyday living such as electricity, trash, gas, and recyclables so you'd be able to count every single move you do. The question is, do you really want to buy a gadget that can only compute carbon footprint when there's the computer for that? I think it's such a waste.
