The ultimate green touring would be not to use an ipod, computer, etc..... All water is natural, I'm assuming the OP means he won't be using plastic "natural" water. And does this rule out no ice or refrigerated water (considering ice takes electricity to make and resources to store). Also the guy appears to have no problem using electricity when it suits him, like standing behind a microphone or using someone's computer like he blogged about so #2 is already shot out the window.
