RE: GM clings to hydrogen, 2015 set for launch
The onboard hydrogen splitter is a lot smaller and lighter than an array of batteries, and the weight/power ratio of the entire system is much better as well. For all the anti GM types, perhaps they can explain why Nissan is a huge proponent of the system as well.
For those who wonder where the electricity will come from - we already have an off-peak surplus, where sources like hydro and nuclear are in over abundance at night. Using this will be considerably cheaper than conventional fuels which are burned during the day to make up for the peak loads.
