I remember seeing something on TV about each home having a hydrogen generator that would provide power for the home and vehicles.
Wonderful! Now you just need to power the hydrogen generator...
It's been quite some time since I saw it but, if I recall correctly, a generator was powered by hydrogen and used to generate electricity for the home and vehicles. Maybe I shouldn't post immediately after waking up and maybe I am closer than I care to admit to being old and forgetful.
