A very interesting green power solution is the SAM (salt-water, air and magnesium) cell technology. Its almost free electricity from abundantly available sea-water. Read about this cool technology: Greenvolt and MagPowerSystems and press release here with pricing.
What is more interesting it has much higher power density to lead-acid battery and more enviornment friendly as well. A SAM cell 1/10th weight of a typical lead-acid battery can give 100watts of output and can sustain loads upto 35 hours.
