You didn't list the other key component on your patent application: What
is this boxed marked "MOH " where electricity goes in at the "gas"
station and methanol comes out?
One of the main problems with an all-electric vehicle is fast charging,
or charging at all. Swapping out a liquid battery is clever, if you can
get it to work. Any fuel cell fuel is great if you can make it and get
it to "gas" stations more efficiently than petrol.
[This spot for a wild and crazy idea.]:
Create tracking intense light projecting zones on streets, highways, and
especially hills. Use grates, mirrors, whatever. As photo-rechargeable
cars drive over the charging zones, focused, high intensity light
illuminates just the receptors on the bottom of cars. The intense pulse
is captured by multi-layer / fractal / nano receivers and the impulse is
stored in capacitor banks that slowly drain into the batteries /
wheels. Presto: an optical (or microwave, or even inductive) "third
rail". Probable power scale mismatch, probably safety issues...
 MOH = Magic occurs here.
