It looks like the world's first rotary hydrogen vehicle will soon be available for lease, courtesy of Mazda. True to its nature as a hybrid, the Premacy Hydrogen RE relies on a hydrogen rotary engine to create the electricity that powers the motor. The system is said to boost the fuel range of the vehicle to around 125 miles, twice the range of the RX-8 Hydrogen RE, and maximum output is 110 kilowatts. We look forward to seeing the cars start rolling off the lots and into the hands of local authorities and energy-related companies this year. Finally, it looks like you'll be able to put that hydrogen generator you installed in the garage to good use.
