Can anyone suggest an alternative to energy from a battery?
I'd like a system to replace my deep cycle leisure battery, I currently use this 110 AH leisure battery with a 1200W inverter. I run my computer, lighting and sound system off it while I'm "out in the sticks", It works just perfect, there's more than enough energy to get a couple of days usage between charges, I just wanted to know if there's a greener way of storing the energy - instead of using ye olde plastic box full of acid and corroding metal.
I'm not interested in using a diesel or petrol generator, I'm looking for something a bit cleaner and greener than that, was thinking about the possibility of running a dynamo off a bottle of pressurized gas or air? - I'd probably need an unfeasibly large tank for this tho!
