Thank you for sharing the ideas. It's curious and good energy saving system we feel. I would like to propose that is it possible to create more compact generator/battery for hand-carry or use in my home? It's more convenience whether gym users or not. In addition, if you can charge back to my credit card or get money by vending machine for my accumulated energy, it's more convenience way to exchange or keep my motivation.
It's interested to read it. This is my simple question that is it available to take a picture the food like my lunch and send then calculate the calorie automatically? It's very easy way to understand it's the high calorie food or not. or I'm living in Japan and I like to use Amazon. Can it be encourage me to buy http://Amazon.com or http://Amazon.jp to choose the appropriate food in stead?
